Description

Technical Field

[0001] This application belongs to the technical field of heat shrink tool holder inspection, specifically relating to an inspection device for heat shrink tool holders. Background Technology

[0002] Heat shrink tool holders are heat-fitting systems that use the difference in thermal expansion coefficients between the tool holder and the tool to clamp the tool with power and high precision. Heat shrink tool holders are generally made of special stainless steel materials with a high thermal expansion coefficient, which can achieve low-temperature heat fitting up to 300°C. They can handle all machining processes from high-speed finishing to heavy cutting, such as milling, drilling, and reaming.

[0003] Before the heat shrink tool holder leaves the factory or after a period of use, the clamping force of the heat shrink tool holder needs to be tested to ensure the clamping safety of the heat shrink tool holder for the tool and to ensure the stable operation of the tool. Currently, when testing the clamping force of heat shrink tool holders, the usual method is to first install a testing rod in the tool holder hole of the heat shrink tool holder, then connect a tension gauge to the testing rod, and then apply a tension force to the tension gauge away from the heat shrink tool holder. If the tension force on the tension gauge is greater than the set value, the testing rod has disengaged from the tool holder hole, or the displacement of the testing rod relative to the heat shrink tool holder is greater than the standard value, then the heat shrink tool holder is unqualified and cannot be used to clamp tools. Conversely, if the tension force on the tension gauge is greater than the set value, the testing rod has not displaced relative to the heat shrink tool holder, or the displacement of the testing rod relative to the heat shrink tool holder is less than the standard value, then the heat shrink tool holder is qualified and can be used to clamp tools. However, because it is difficult to control the tension force applied to the tension gauge precisely, it is impossible to ensure that the tension force on the tension gauge and the testing rod are coaxial, thus affecting the accuracy of the test results when testing the clamping force of the heat shrink tool holder, and consequently, making it impossible to accurately determine whether the heat shrink tool holder is qualified. Utility Model Content

[0004] This application provides a testing device for heat shrink tool holders to improve the accuracy of the test results when testing the clamping force of heat shrink tool holders, so as to accurately determine whether the heat shrink tool holders are qualified.

[0005] The technical solution adopted in this application is as follows:

[0006] A detection device for heat-shrink tool holders, comprising:

[0007] frame;

[0008] The detection component includes a pressure sensor disposed on the frame and a detection rod disposed on the pressure sensor, wherein the pressure sensor is capable of detecting the pressure applied to the detection rod;

[0009] A movable assembly includes a movable base slidably connected to the frame and a drive member disposed on the frame. The movable base has a mounting position for mounting a heat shrink tool holder. The drive member is used to drive the movable base to move toward or away from the detection rod, so that the detection rod can extend into or disengage from the tool holder hole of the heat shrink tool holder mounted at the mounting position.

[0010] By adopting the above technical solution, when using the detection device of this application to detect the clamping force of the heat shrink tool holder, the heat shrink tool holder is first installed in the mounting position, and then the drive unit is started, which then drives the moving seat, causing the moving seat to move the heat shrink tool holder towards a position closer to the heat shrink tool holder, thereby making the distance between the heat shrink tool holder and the detection rod smaller and smaller. When the heat shrink tool holder contacts the detection rod, the detection rod is subjected to pressure, so that the pressure sensor receives the pressure transmitted through the detection rod, and the position of the moving seat at this time is recorded as the first position; the drive unit continues to drive the moving seat, and the moving seat drives the heat shrink tool holder to continue moving towards the side where the detection rod is located, thereby making the pressure on the detection rod gradually increase. When the pressure sensor detects that the pressure on the detection rod reaches the set value, the drive unit stops driving the moving seat and records the position of the moving seat at this time as the second position. Then, the distance between the first position and the second position is calculated, which is the depth of the detection rod inserted into the tool holder hole. The distance between the first position and the second position is compared with the standard value range. If the distance between the first position and the second position is greater than the standard value range, it means that the clamping force of the heat shrink tool holder is unqualified, and it can be concluded that the heat shrink tool holder is unusable. If the distance between the first position and the second position is less than the standard value range, it means that the clamping force of the heat shrink tool holder is qualified, and it can be concluded that the heat shrink tool holder is usable.

[0011] After the heat shrink tool holder is inspected, the drive unit drives the moving seat to move away from the inspection rod, so that the moving seat moves the heat shrink tool holder away from the inspection rod, thereby gradually separating the heat shrink tool holder from the inspection rod. After the heat shrink tool holder is separated from the inspection rod, the heat shrink tool holder can be removed from the mounting position.

[0012] When using the detection device of this application to detect the clamping force of a heat shrink tool holder, the pressure on the detection rod is always coaxial with the axis of the heat shrink tool holder. The detection rod is located on a pressure sensor, which can accurately determine the pressure on the detection rod. This avoids situations where the force on the detection rod is at an angle to the axis of the heat shrink tool holder, which would prevent accurate detection of the force on the detection rod. This improves the accuracy of the detection results when detecting the clamping force of the heat shrink tool holder.

[0013] Furthermore, when using the detection device in this application to detect the clamping force of the heat shrink tool holder, it is only necessary to install the heat shrink tool holder into the mounting position, and the remaining steps can be completed automatically, thereby improving the efficiency of detecting the clamping force of the heat shrink tool holder and reducing the labor input cost when detecting the clamping force of the heat shrink tool holder, thus reducing the cost of detecting the clamping force of the heat shrink tool holder.

[0014] Optionally, the movable seat is provided with a support body, the support body having a positioning hole into which at least a portion of the heat-shrinking handle can extend.

[0015] By adopting the above technical solution, when installing the heat shrink tool holder, the heat shrink tool holder is placed on the support body, and at least a portion of the heat shrink tool holder extends into the positioning hole. The portion of the heat shrink tool holder extending into the positioning hole abuts against the hole wall, thereby using the positioning hole to support and position the heat shrink tool holder. This increases the stability of the heat shrink tool holder, ensuring the accuracy of the clamping force detection results. Furthermore, it enables automatic positioning of the heat shrink tool holder by utilizing the cooperation between the positioning hole and the heat shrink tool holder, thereby reducing the installation difficulty of the heat shrink tool holder and further improving the efficiency of clamping force detection.

[0016] Optionally, the movable seat is provided with a clamping structure, which is located on the side of the support and is capable of applying a clamping force toward the side of the support to the heat shrink handle located at the mounting position.

[0017] By adopting the above technical solution, after the heat shrink tool holder is installed in the mounting position, the clamping structure begins to move, eventually contacting the heat shrink tool holder and applying a clamping force on the side where the support body is located, thereby fixing the heat shrink tool holder in the mounting position. This further increases the stability of the heat shrink tool holder and improves the accuracy of the clamping force test results. In addition, by setting the clamping structure to fix the heat shrink tool holder in the mounting position, it also avoids the situation where the heat shrink tool holder cannot follow the movement of the moving seat when it moves away from the detection rod, thus improving the efficiency of removing the heat shrink tool holder from the detection rod and further improving the detection efficiency of clamping force test results.

[0018] Optionally, the clamping structure includes a rotary cylinder, the piston rod of which has a downward pressing arm that can abut against the cylindrical portion of the heat shrink handle.

[0019] By adopting the above technical solution, after the heat shrink tool holder is installed in the mounting position, the piston rod of the corner cylinder drives the lower pressure arm to rotate, thereby causing at least a portion of the lower pressure arm to be positioned opposite the cylindrical portion of the heat shrink tool holder. Then, the piston rod of the corner cylinder retracts, ultimately causing the lower pressure arm to contact the cylindrical portion of the heat shrink tool holder and apply pressure to the cylindrical portion of the heat shrink tool holder on the side where the support body is located, thus completing the fixation of the heat shrink tool holder in the mounting position. By setting the clamping structure as a corner cylinder, the cost of the clamping structure is reduced on the one hand, and the fixation stability of the heat shrink tool holder is increased on the other hand.

[0020] Optionally, the detection device further includes a position sensor capable of detecting the position of the movable seat.

[0021] By adopting the above technical solution, since the position sensor can detect the position of the moving seat, it is possible to use the position sensor to detect the location of the moving seat, so as to facilitate the calculation of the distance between the first position and the second position, thereby further improving the efficiency of the clamping force detection of the heat shrink tool holder and further improving the accuracy of the detection result of the clamping force detection of the heat shrink tool holder.

[0022] Optionally, the position sensor includes a ranging sensor, which is located on the side of the movable seat facing the detection rod or on the side of the movable seat away from the detection rod.

[0023] Alternatively, the position sensor may include a photoelectric transmitter disposed on the frame and a receiver disposed on the movable base, with the photoelectric transmitter located on the side of the movable base.

[0024] By adopting the above technical solution, since the position sensor includes a ranging sensor, the distance between the moving seat and the ranging sensor when the moving seat is in the first position can be directly measured through the ranging sensor, and the distance between the moving seat and the ranging sensor when the moving seat is in the second position can also be directly measured through the ranging sensor, so as to further achieve the effect of facilitating the calculation of the distance between the first position and the second position.

[0025] Since the position sensor includes a photoelectric transmitter and a receiver, it is possible to set the initial position when the photoelectric transmitter and receiver are relative to each other, set the first position as the distance to the initial position, and set the second position as the distance to the initial position. Thus, the distance between the first position and the initial position can be calculated using the time it takes for the moving base to move from the initial position to the first position and in combination with other parameters of the driving component. Similarly, the distance between the second position and the initial position can be calculated using the time it takes for the moving base to move from the initial position to the second position and in combination with other parameters of the driving component.

[0026] Optionally, the detection rod has a central hole, a connecting rod is provided between the detection rod and the pressure sensor, the connecting rod has a communicating hole communicating with the central hole, and a tracheal connector communicating with the communicating hole is provided on the side of the connecting rod.

[0027] By adopting the above technical solution, before testing the clamping force of the heat shrink tool holder, the external air supply device is connected to the air pipe connector so that the high-pressure gas produced by the external air supply device can be delivered to the central hole through the air pipe connector and the connecting hole. Then, when testing the clamping force of the heat shrink tool holder, the high-pressure gas can flow out through the central hole and enter the tool holder hole of the heat shrink tool holder to achieve purging of the tool holder hole, thereby avoiding the situation where dust in the tool holder hole affects the test results, and further improving the accuracy of the test results of the clamping force of the heat shrink tool holder.

[0028] Optionally, the driving component includes a servo motor and a lead screw assembly. The lead screw assembly includes a lead screw and a nut threaded to the lead screw. The output shaft of the servo motor is driven to the lead screw, and the nut is fixedly connected to the movable base.

[0029] By adopting the above technical solution, when driving the moving seat, the output shaft of the servo motor drives the lead screw to rotate, which in turn causes the lead screw and nut to rotate relative to each other. Simultaneously, the nut moves along the lead screw axis, thereby driving the moving seat to move. By combining the driving component with a servo motor and a lead screw pair, the stability and smoothness of the moving seat's movement are ensured, while the cost of the driving component is reduced, thus lowering the manufacturing cost of the detection device.

[0030] Optionally, the frame is provided with a slide rail, and the movable seat is provided with a slider that is slidably connected to the slide rail.

[0031] By adopting the above technical solution, when the moving seat moves under the action of the driving component, the moving seat drives the slider to move, which in turn causes the slider and the slide rail to slide relative to each other. On the one hand, the sliding cooperation between the slider and the slide rail can guide the movement of the moving seat to increase the stability of the moving seat during movement. On the other hand, the cooperation between the slider and the slide rail can also increase the stability of the moving seat, thereby further increasing the accuracy of the detection results when performing clamping force detection on the heat shrink tool holder.

[0032] Optionally, the detection device further includes a display that can display the pressure received by the pressure sensor and the depth to which the detection rod is inserted into the tool holder hole;

[0033] And / or, the frame has a shielding side and an operating side in its circumference, the shielding side is provided with a protective plate, and the operating side is provided with a light curtain, the light curtain being able to send a stop signal to the drive unit.

[0034] By adopting the above technical solution, the display can show the pressure received by the pressure sensor and the depth of the detection rod inserted into the tool holder hole, thereby making the pressure received by the detection rod and the depth of the detection rod inserted into the tool holder hole visible, so that the staff can more accurately judge whether the heat shrink tool holder is qualified.

[0035] Because a protective plate is installed on the shielding side, the safety of using the detection device to detect the clamping force of the heat shrink tool holder is increased. Furthermore, because a light curtain is installed on the operating side, when the infrared light emitted by the light curtain is blocked, the light curtain can send a stop signal to the drive unit, thereby further increasing the safety of using the detection device to detect the clamping force of the heat shrink tool holder.

[0036] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0037] 1. The detection device of this application includes a frame, a detection component, and a moving component. The detection component includes a pressure sensor mounted on the frame and a detection rod mounted on the pressure sensor. The pressure sensor can detect the pressure on the detection rod. The moving component includes a movable seat slidably connected to the frame and a drive component mounted on the frame. The movable seat has a mounting position for mounting a heat shrink tool holder. The drive component drives the movable seat to move towards or away from the detection rod, so that the detection rod can extend into or disengage from the tool holder hole of the heat shrink tool holder mounted at the mounting position. Therefore, when using the detection device of this application to detect the clamping force of the heat shrink tool holder, the pressure on the detection rod is always coaxial with the axial direction of the heat shrink tool holder. Since the detection rod is mounted on the pressure sensor, the pressure on the detection rod can be accurately obtained through the pressure sensor, avoiding the situation where the force on the detection rod is at an angle with the axial direction of the heat shrink tool holder, which would prevent accurate detection of the force on the detection rod. This improves the accuracy of the detection results when detecting the clamping force of the heat shrink tool holder.

[0038] 2. In this application, the movable base is provided with a support body, and the support body is provided with a positioning hole into which at least a portion of the heat shrink tool holder can extend. When installing the heat shrink tool holder, the heat shrink tool holder is placed on the support body, and then at least a portion of the heat shrink tool holder extends into the positioning hole, so that the portion of the heat shrink tool holder extending into the positioning hole abuts against the hole wall of the positioning hole, thereby using the positioning hole to support and position the heat shrink tool holder. This increases the stability of the heat shrink tool holder, ensuring the accuracy of the clamping force detection results of the heat shrink tool holder. On the other hand, it realizes automatic positioning of the heat shrink tool holder by using the cooperation of the positioning hole and the heat shrink tool holder, thereby reducing the installation difficulty of the heat shrink tool holder and further improving the efficiency of clamping force detection of the heat shrink tool holder.

[0039] 3. In this application, the movable seat is provided with a clamping structure. The clamping structure is located on the side of the support body and can apply a clamping force towards the side of the support body to the heat shrink tool holder at the mounting position. After the heat shrink tool holder is installed in the mounting position, the clamping structure starts to move, eventually making the clamping structure contact the heat shrink tool holder and apply a clamping force towards the side of the support body to the heat shrink tool holder, thereby fixing the heat shrink tool holder in the mounting position. This further increases the stability of the heat shrink tool holder and further improves the accuracy of the detection results when performing clamping force detection on the heat shrink tool holder. In addition, by setting the clamping structure to fix the heat shrink tool holder in the mounting position, it also avoids the situation where the heat shrink tool holder cannot follow the movement of the movable seat when it moves away from the detection rod, thereby improving the efficiency of removing the heat shrink tool holder from the detection rod and further improving the detection efficiency when performing clamping force detection on the heat shrink tool holder.

[0047] Many specific details are set forth in the following description in order to provide a full understanding of this application.

[0049] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0050] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "implementation," "example," "a particular embodiment," "example," or "specific example," etc., indicate that the specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0051] Reference Figures 1 to 3 A detection device for heat shrink tool holders is disclosed, comprising a frame 1, a detection component 2, and a moving component 3. The detection component 2 includes a pressure sensor 21 disposed on the frame 1 and a detection rod 22 disposed on the pressure sensor 21. The pressure sensor 21 can detect the pressure on the detection rod 22. The moving component 3 includes a moving seat 31 slidably connected to the frame 1 and a driving member 32 disposed on the frame 1. The moving seat 31 has a mounting position for mounting a heat shrink tool holder 7. The driving member 32 is used to drive the moving seat 31 to move toward or away from the detection rod 22, so that the detection rod 22 can extend into or disengage from the tool holder hole of the heat shrink tool holder 7 mounted at the mounting position.

[0052] Understandably, after the heat shrink tool holder 7 is installed in the mounting position, the tool holder hole of the heat shrink tool holder 7 is coaxial with the detection rod 22, and the moving seat 31 can move along the axial direction of the detection rod 22 under the action of the driving member 32.

[0053] It should be noted that when the moving seat 31 moves toward the direction of the detection rod 22 under the action of the driving member 32, the detection rod 22 gradually extends into the tool holder hole of the heat shrink tool holder 7 as the moving seat 31 continues to move; while when the moving seat 31 moves away from the direction of the detection rod 22 under the action of the driving member 32, the detection rod 22 gradually disengages from the tool holder hole as the moving seat 31 continues to move.

[0054] When using the detection device of this application to detect the clamping force of the heat shrink tool holder 7, the heat shrink tool holder 7 is first installed in the mounting position. Then, the drive unit 32 is activated, which drives the moving seat 31 to move the heat shrink tool holder 7 closer to the heat shrink tool holder 7. This reduces the distance between the heat shrink tool holder 7 and the detection rod 22. When the heat shrink tool holder 7 contacts the detection rod 22, the detection rod 22 is subjected to pressure, causing the pressure sensor 21 to receive the pressure transmitted through the detection rod 22. The position of the moving seat 31 at this time is then recorded as the first position. The drive unit 32 continues to drive the moving seat 31, which drives the heat shrink tool holder 7 to continue moving towards the side where the detection rod 22 is located, thus reducing the pressure on the detection rod 22. As the pressure gradually increases, when the pressure sensor 21 detects that the pressure on the detection rod 22 reaches the set value, the drive component 32 stops driving the moving seat 31 and records the position of the moving seat 31 at this time as the second position. Then, the distance between the first position and the second position is calculated, that is, the depth of the detection rod 22 inserted into the tool holder hole is calculated, and the distance between the first position and the second position is compared with the standard value range. If the distance between the first position and the second position is greater than the standard value range, it means that the clamping force of the heat shrink tool holder 7 is unqualified, that is, it can be concluded that the heat shrink tool holder 7 cannot be used; if the distance between the first position and the second position is less than the standard value range, it means that the clamping force of the heat shrink tool holder 7 is qualified, that is, it can be concluded that the heat shrink tool holder 7 can be used.

[0055] After the heat shrink handle 7 is inspected, the drive unit 32 drives the moving seat 31 to move away from the detection rod 22, so that the moving seat 31 drives the heat shrink handle 7 to move away from the detection rod 22, thereby gradually separating the heat shrink handle 7 from the detection rod 22. After the heat shrink handle 7 is separated from the detection rod 22, the heat shrink handle 7 can be removed from the installation position.

[0056] When using the detection device of this application to detect the clamping force of the heat shrink tool holder 7, the pressure on the detection rod 22 is always coaxial with the axis of the heat shrink tool holder 7. The detection rod 22 is located on the pressure sensor 21, so the pressure on the detection rod 22 can be accurately obtained through the pressure sensor 21. This avoids the situation where the force on the detection rod 22 is at an angle with the axis of the heat shrink tool holder 7, which would prevent the force on the detection rod 22 from being accurately detected. This improves the accuracy of the detection results when detecting the clamping force of the heat shrink tool holder 7.

[0057] Furthermore, when using the detection device of this application to detect the clamping force of the heat shrink tool holder 7, it is only necessary to install the heat shrink tool holder 7 into the mounting position, and the remaining steps can be completed automatically, thereby improving the efficiency of detecting the clamping force of the heat shrink tool holder 7 and reducing the manpower input cost when detecting the clamping force of the heat shrink tool holder 7, thereby reducing the cost of detecting the clamping force of the heat shrink tool holder 7.

[0058] This application does not specify the method of forming the mounting position; preferably, refer to... Figure 1 and Figure 2 The movable seat 31 is provided with a support body 312, and the support body 312 is provided with a positioning hole into which at least a portion of the heat-shrinking handle 7 can extend.

[0059] Understandably, the shape of the positioning hole is adapted to the shape of the part of the heat shrink tool holder 7 that can extend into the positioning hole. The support body 312 is fixedly connected to the movable seat 31, and the support body 312 forms a mounting position. After the heat shrink tool holder 7 is installed on the support body 312, the part of the heat shrink tool holder 7 that extends into the positioning hole abuts against the hole wall of the positioning hole, and the cylindrical part of the heat shrink tool holder 7 abuts against the support body 312, so that the support body 312 supports the heat shrink tool holder 7.

[0060] When installing the heat shrink tool holder 7, the heat shrink tool holder 7 is placed on the support body 312, and at least a portion of the heat shrink tool holder 7 extends into the positioning hole, so that the portion of the heat shrink tool holder 7 extending into the positioning hole abuts against the hole wall of the positioning hole, thereby using the positioning hole to support and position the heat shrink tool holder 7. This increases the stability of the heat shrink tool holder 7, ensuring the accuracy of the clamping force detection results of the heat shrink tool holder 7, and also realizes automatic positioning of the heat shrink tool holder 7 by using the cooperation between the positioning hole and the heat shrink tool holder 7, thereby reducing the installation difficulty of the heat shrink tool holder 7 and further improving the efficiency of clamping force detection of the heat shrink tool holder 7.

[0061] Furthermore, refer to Figure 1 and Figure 2 The movable seat 31 is provided with a clamping structure 313, which is located on the side of the support body 312 and can apply a clamping force to the heat shrink handle 7 located in the mounting position toward the side of the support body 312.

[0062] After the heat shrink tool holder 7 is installed in the mounting position, the clamping structure 313 begins to move, eventually contacting the heat shrink tool holder 7 and applying a clamping force on the side where the support body 312 is located, thereby fixing the heat shrink tool holder 7 in the mounting position. This further increases the stability of the heat shrink tool holder 7 and improves the accuracy of the clamping force test results. In addition, by fixing the heat shrink tool holder 7 in the mounting position with the clamping structure 313, the situation where the heat shrink tool holder 7 cannot follow the movement of the moving seat 31 when it moves away from the detection rod 22 is avoided is prevented. This improves the efficiency of removing the heat shrink tool holder 7 from the detection rod 22 and further improves the detection efficiency of clamping force test results.

[0063] This application does not specifically limit the clamping structure 313; preferably, refer to... Figure 1 and Figure 2 The clamping structure 313 includes a rotary cylinder, the piston rod of which has a downward pressing arm that can abut against the cylindrical portion of the heat shrink handle 7.

[0064] After the heat shrink tool holder 7 is installed in the mounting position, the piston rod of the corner cylinder drives the lower pressure arm to rotate, so that at least a part of the lower pressure arm is opposite to the cylindrical part of the heat shrink tool holder 7. Then the piston rod of the corner cylinder retracts, and finally the lower pressure arm contacts the cylindrical part of the heat shrink tool holder 7 and applies pressure to the cylindrical part of the heat shrink tool holder 7 on the side where the support 312 is located, thereby completing the fixation of the heat shrink tool holder 7 in the mounting position. By setting the clamping structure 313 as a corner cylinder, the cost of the clamping structure 313 is reduced on the one hand, and the fixation stability of the heat shrink tool holder 7 is increased on the other hand.

[0065] Preferably, there are two corner cylinders, which are located on opposite sides of the positioning hole. This increases the number of fixing points for the heat shrink tool holder 7 located in the mounting position and ensures the force balance of the heat shrink tool holder 7, thereby further increasing the stability of the heat shrink tool holder 7.

[0066] Preferably, a pressure rod is provided at the end of the lower pressure arm away from the piston rod. The pressure rod is located on the side of the lower pressure arm facing the support body 312. An elastic sleeve is provided at the end of the pressure rod away from the lower pressure arm so that the lower pressure arm applies pressure to the cylindrical part of the heat shrink tool holder 7 through the elastic sleeve, so as to avoid possible damage to the heat shrink tool holder 7.

[0067] In other embodiments, the clamping structure 313 may also include a cylinder and an annular structure. The annular structure is fixedly connected to the piston rod of the cylinder and can be sleeved on the outside of the heat shrink handle 7 and can abut against the cylindrical portion of the heat shrink handle 7 to apply a clamping force toward the side where the support body 312 is located. Alternatively, the clamping structure 313 includes an annular structure and a bolt passing through the annular structure. The annular structure can be sleeved on the outside of the heat shrink handle 7, and the bolt can be threaded to the support body 312 or the movable seat 31 to apply a clamping force toward the side where the support body 312 is located using the bolt, thereby fixing the heat shrink handle 7.

[0068] In other embodiments, the mounting position may also be formed by a hole structure directly provided on the movable base 31.

[0069] In a preferred embodiment, refer to Figure 2 The detection device also includes a position sensor 4, which can detect the position of the movable seat 31.

[0070] Since the position sensor 4 can detect the position of the moving seat 31, the position of the moving seat 31 can be detected by the position sensor 4, so as to facilitate the calculation of the distance between the first position and the second position, thereby further improving the efficiency of the clamping force detection of the heat shrink tool holder 7 and further improving the accuracy of the detection result of the clamping force detection of the heat shrink tool holder 7.

[0071] This application does not impose specific limitations on the structure of the position sensor 4, which can adopt any of the following embodiments:

[0072] Example 1: In this example, the position sensor 4 includes a ranging sensor, which can detect the position of the movable seat 31.

[0073] Since the position sensor 4 includes a distance sensor, the distance between the moving seat 31 and the distance sensor when the moving seat 31 is in the first position can be directly measured by the distance sensor, and the distance between the moving seat 31 and the distance sensor when the moving seat 31 is in the second position can also be directly measured by the distance sensor, so as to further facilitate the calculation of the distance between the first position and the second position.

[0074] This application does not specify the location of the ranging sensor. It can be fixed on the frame 1 and located on the side of the movable seat 31 facing the detection rod 22 or on the side of the movable seat 31 away from the detection rod 22; or, the ranging sensor is fixedly connected to the movable seat 31 with the detection direction parallel to the moving direction of the movable seat 31, so as to use the ranging sensor to detect the distance from the movable seat 31 to the end of the frame 1.

[0075] Example 2, in this example, refer to Figure 2 The position sensor 4 includes a photoelectric transmitter 41 disposed on the frame 1 and a receiver 42 disposed on the movable base 31, and the photoelectric transmitter 41 is located on the side of the movable base 31.

[0076] It is understandable that when the receiver 42 is located opposite the photoelectric transmitter 41, the receiver 42 is able to receive the signal emitted by the photoelectric transmitter 41.

[0077] It should be noted that if the position of the movable seat 31 when the receiver 42 is opposite to the photoelectric transmitter 41 is defined as the initial position, then when the movable seat 31 moves toward the direction of the detection rod 22, it will pass through the initial position and the first position in sequence before reaching the second position.

[0078] Since the position sensor 4 includes a photoelectric transmitter 41 and a receiver 42, it is possible to set the photoelectric transmitter 41 and the receiver 42 relative to each other as the initial position, set the first position as the distance to the initial position, and set the second position as the distance to the initial position. Thus, the distance between the first position and the initial position can be calculated using the time it takes for the moving base 31 to move from the initial position to the first position and in combination with other parameters of the driving member 32. Similarly, the distance between the second position and the initial position can be calculated using the time it takes for the moving base 31 to move from the initial position to the second position and in combination with other parameters of the driving member 32.

[0079] Of course, in other embodiments, the position sensor 4 may also be a proximity switch or other electrical component capable of detecting the position of the movable seat 31.

[0080] In a preferred embodiment, the detection device further includes a programmable logic controller (PLC), and the drive unit 32 and the position sensor 4 are all electrically connected to the PLC, so that the PLC can control the start and stop of the drive unit 32, and the position sensor 4 can send a signal to the PLC to calculate the distance between the first position and the second position, so as to further improve the accuracy of the detection result when detecting the clamping force of the heat shrink tool holder 7.

[0081] In a preferred embodiment, refer to Figure 1 and Figure 2 The detection rod 22 has a central hole, and a connecting rod 221 is provided between the detection rod 22 and the pressure sensor 21. The connecting rod 221 has a connecting hole that communicates with the central hole, and a tracheal connector that communicates with the connecting hole is provided on the side of the connecting rod 221.

[0082] Understandably, the detection rod 22 is connected to the pressure sensor 21 via the connecting rod 221.

[0083] Before testing the clamping force of the heat shrink tool holder 7, the external air supply device is connected to the air pipe connector so that the high-pressure gas produced by the external air supply device can be delivered to the central hole through the air pipe connector and the connecting hole. Then, when testing the clamping force of the heat shrink tool holder 7, the high-pressure gas can flow out through the central hole and enter the tool holder hole of the heat shrink tool holder 7 to purge the tool holder hole, thereby avoiding the situation where dust in the tool holder hole affects the test results, and further improving the accuracy of the test results of the clamping force of the heat shrink tool holder 7.

[0084] Furthermore, the end of the detection rod 22 away from the pressure sensor 21 is chamfered to ensure that the end of the detection rod 22 away from the pressure sensor 21 can extend into the tool holder hole, thereby improving the purging effect of high-pressure gas on the tool holder hole and further improving the accuracy of the detection result of the clamping force of the heat shrink tool holder 7.

[0085] This application does not specifically limit the structure of the drive component 32; preferably, refer to... Figure 2 and Figure 3 The drive unit 32 includes a servo motor 321 and a lead screw pair 322. The lead screw pair 322 includes a lead screw and a nut threaded to the lead screw. The output shaft of the servo motor 321 is driven to the lead screw, and the nut is fixedly connected to the moving base 31.

[0086] It is understandable that the servo motor 321 is fixedly connected to the frame 1, the lead screw is rotatably connected to the frame 1, and the lead screw is set parallel to the central axis of the detection rod 22.

[0087] When the moving base 31 is driven to move, the output shaft of the servo motor 321 drives the lead screw to rotate, which in turn causes the lead screw and the nut to rotate relative to each other. At the same time, the nut moves along the axial direction of the lead screw, thereby driving the moving base 31 to move, thus realizing the driving of the moving base 31. By setting the driving component 32 as a combination of the servo motor 321 and the lead screw pair 322, on the one hand, the stability of driving the moving base 31 is ensured, and the smoothness of the movement of the moving base 31 is guaranteed. On the other hand, the cost of the driving component 32 is reduced, thereby reducing the manufacturing cost of the detection device.

[0088] It should be noted that in the above-mentioned position sensor 4 including photoelectric transmitter 41 and receiver 42, the programmable logic controller can calculate the distance between the first position and the initial position by combining the time taken for the moving base 31 to move from the initial position to the first position, the rotation speed of the servo motor 321 during this time, and the displacement of the nut when the lead screw rotates one revolution. The programmable logic controller can calculate the distance between the second position and the initial position by combining the time taken for the moving base 31 to move from the initial position to the second position, the rotation speed of the servo motor 321 during this time, and the displacement of the nut when the lead screw rotates one revolution, and then calculate the distance between the first position and the second position.

[0089] This application does not specify a particular method for the transmission connection between the output shaft of the servo motor 321 and the lead screw. Preferably, the output shaft of the servo motor 321 is connected to the lead screw via a coupling to ensure the stability of the transmission connection. In other embodiments, the output shaft of the servo motor 321 can also be connected to the lead screw via welding or other methods.

[0090] In other embodiments, the drive unit 32 may also be a linear motor, cylinder, hydraulic cylinder, electric actuator, or other structure capable of driving the movable seat 31 to perform linear motion.

[0091] In a preferred embodiment, refer to Figures 1 to 3 The frame 1 is provided with a slide rail 11, and the movable seat 31 is provided with a slider 314 that is slidably connected to the slide rail 11.

[0092] It is understood that the movable base 31 is slidably connected to the frame 1 via the slider 314 and the slide rail 11, the slide rail 11 is fixedly connected to the frame 1, and the slider 314 is fixedly connected to the movable base 31.

[0093] When the movable seat 31 moves under the action of the driving member 32, the movable seat 31 drives the slider 314 to move, which in turn causes the slider 314 to slide relative to the slide rail 11. On the one hand, the sliding cooperation between the slider 314 and the slide rail 11 can guide the movement of the movable seat 31 to increase the stability of the movable seat 31 during movement. On the other hand, the cooperation between the slider 314 and the slide rail 11 can also increase the stability of the movable seat 31, thereby further increasing the accuracy of the detection results when performing clamping force detection on the heat shrink tool holder 7.

[0094] Preferably, there are two slide rails 11, and the two slide rails 11 are located on both sides of the nut. The slider 314 is provided with two slide rails 11 to further increase the stability of the moving seat 31.

[0095] In a preferred embodiment, refer to Figures 1 to 3The detection device also includes a display 5, which can display the pressure received by the pressure sensor 21 and the depth to which the detection rod 22 is inserted into the tool holder hole.

[0096] It is understandable that the programmable logic controller (PLC) is electrically connected to the display 5, thereby enabling the pressure signal sent by the pressure sensor 21 to the PLC to be processed by the PLC and displayed on the display 5, and the depth of the detection rod 22 inserted into the tool holder hole obtained by the PLC using the first position and second position information to be displayed on the display 5.

[0097] Since the display 5 can display the pressure received by the pressure sensor 21 and the depth of the detection rod 22 inserted into the tool holder hole, it can visualize the pressure received by the detection rod 22 and the depth of the detection rod 22 inserted into the tool holder hole, so that the staff can more accurately judge whether the heat shrink tool holder 7 is qualified.

[0098] In a preferred embodiment, refer to Figures 1 to 3 The frame 1 has a shielding side and an operating side in its circumference. The shielding side is provided with a protective plate 12, and the operating side is provided with a light curtain 13. The light curtain 13 can send a stop signal to the drive unit 32.

[0099] Specifically, the frame 1 has an internal installation space, and the movable base 31, the detection rod 22, and the pressure sensor 21 are located inside the installation space.

[0100] It should be noted that the light curtain 13 is a safety protection device based on the photoelectric sensing principle. It forms a detection area by emitting infrared rays. When the infrared rays are blocked, a stop signal is triggered. The light curtain 13 is electrically connected to the programmable logic controller. After the infrared rays emitted by the light curtain 13 are blocked, the light curtain 13 sends a signal to the programmable logic controller, so that the programmable logic controller sends a stop signal to the drive unit 32.

[0101] Because the shielding side is equipped with a protective plate 12, the safety of using the detection device to detect the clamping force of the heat shrink tool holder 7 is increased. Furthermore, because the operating side is equipped with a light curtain 13, when the infrared light emitted by the light curtain 13 is blocked, the light curtain 13 can send a stop signal to the drive unit 32, thereby further increasing the safety of using the detection device to detect the clamping force of the heat shrink tool holder 7.

[0102] Preferably, the light curtain 13 is located at the bottom of the installation space and emits infrared rays upward.

[0103] This application does not specifically limit the relative positional relationship between the detection rod 22 and the movable seat 31. Preferably, the detection rod 22 is located above the movable seat 31, so that the movable seat 31 needs to move upward when the clamping force of the heat shrink handle 7 is tested, thereby reducing the difficulty of fixing the heat shrink handle 7 and increasing the stability of the heat shrink handle 7.

[0104] Preferably, the servo motor 321 is located outside the mounting space and at the bottom of the mounting space, and the top of the frame 1 has multiple legs, with the servo motor 321 located between the multiple legs.

[0105] In other embodiments, the detection rod 22 may also be located on the left or right side of the movable seat 31 so that the movable seat 31 needs to be moved in the horizontal direction when the clamping force of the heat shrink handle 7 is detected.

[0106] In a preferred embodiment, refer to Figure 1 and Figure 2 The detection device also includes a cleaning assembly 6 located inside the installation space. The cleaning assembly 6 includes a drive rod motor fixedly connected to the frame 1 and a cleaning rod 62 coaxially fixedly connected to the output shaft of the drive motor 61. The outer peripheral surface of the cleaning rod 62 away from the drive motor 61 is provided with bristles, and the cleaning rod 62 is coaxially arranged with the detection rod 22. The moving base 31 has a support plate 311, and the support body 312 is fixedly connected to the support plate 311. The support plate 311 is provided with a through hole coaxially arranged with the positioning hole. The cleaning rod 62 can extend into the handle hole of the heat shrink handle 7 installed in the installation position through the through hole, so that the output shaft of the drive motor 61 drives the cleaning rod 62 to rotate, thereby causing the bristles on the cleaning rod 62 to clean the hole wall of the handle hole, thereby increasing the cleanliness of the handle hole and avoiding the situation where dust adhering to the handle hole affects the accuracy of the detection results, thereby further increasing the accuracy of the detection results when detecting the clamping force of the heat shrink handle 7.

[0107] Specifically, the cleaning component 6 is located on the side of the support plate 311 away from the detection rod 22. As a result, when the clamping force of the heat shrink handle 7 is tested, the moving seat 31 first drives the heat shrink handle 7 to move towards the side closer to the cleaning component 6 so that the bristles clean the handle hole first. After the bristles have cleaned the handle hole, the moving seat 31 then drives the heat shrink handle 7 to move towards the direction closer to the detection rod 22.
