Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and more specifically to a rotary testing device, and more particularly to a multi-angle graduated rotary testing device. Background Technology

[0002] Currently, industrial products still require testing after production to determine their quality. Rotary tables are typically used during testing to rotate the product for comprehensive inspection. Existing rotary indexing tables generally include pneumatic and electric indexing tables.

[0003] I. Using a pneumatic indexing plate allows for precise stopping at equal indexing intervals, but there are some problems:

[0004] 1. The pneumatic indexing plate adopts a ratchet structure, which can only stop precisely at the specified index (such as 30°, 60°, etc.) and cannot stop in the middle position. Therefore, due to some reasons, there is a blind zone in the rotation indexing during operation.

[0005] 2. The ratchet structure allows the pneumatic indexing plate to rotate only in one direction and not in the opposite direction;

[0006] 3. Each manual operation causes the indexing plate to move once. If there are many indexes, it may take multiple operations to reach the designated position, which is time-consuming.

[0007] Second, while using an electric indexing plate allows for precise stopping with equal indexing intervals and high accuracy, the following problems still exist:

[0008] 1. The CNC indexing plate is used. According to the preset parameters of the motor, the indexing plate stops precisely at the specified division (such as 30°, 60°, etc.) and cannot stop in the middle position. Therefore, due to some reasons, there is a blind zone of rotation indexing during operation.

[0009] 2. If a servo motor or stepper motor is used for driving, it can stop continuously and accurately, but because the π value cannot be accurately set when manually setting parameters, the cumulative error is too large over a long period of time.

[0010] 3. If a power outage occurs during operation, it is necessary to recalibrate the origin, which is a complicated operation;

[0011] 4. The product price is high, and the repair and maintenance costs are also high. Summary of the Invention

[0012] In view of this, the present invention aims to provide a multi-angle indexing rotation detection device to at least solve the technical problem in the prior art that the pneumatic or electric rotating indexing plate can only stop at a specific angle, resulting in limited rotation and difficulty in operation.

[0013] To achieve the above objectives, the present invention adopts the following technical solution:

[0014] A multi-angle indexing rotation detection device, comprising:

[0015] Base;

[0016] An annular turntable is rotatably mounted on the top of the base, and multiple positioning slots are evenly provided on the inner ring wall of the annular turntable along its circumferential direction.

[0017] A locking and positioning mechanism includes an ejection component and a locking and positioning block. The ejection component is fixed on the top of the base corresponding to the inner ring side of the annular turntable. The pushing direction of the ejection component is arranged along the radial direction of the annular turntable. The locking and positioning block is fixed to the ejection end of the ejection component and is in rolling connection with the inner ring wall of the annular turntable.

[0018] An elastic positioning mechanism includes an ejection mechanism and a rotating positioning block. The ejection mechanism is fixed to the top of the base corresponding to the inner ring side of the annular turntable, and its ejection direction is arranged along the radial direction of the annular turntable. The rotating positioning block is rotatably mounted on the ejection end of the ejection mechanism parallel to the axial direction of the annular turntable and is in rolling contact with the inner ring wall of the annular turntable. The rotating positioning block and the locking positioning block can be respectively positioned and connected to any two of the positioning slots.

[0019] A pressure-operated mechanical valve is fixed to the top of the base and its pressure end contacts the ejection end of the ejection mechanism. It is connected to the ejection assembly to control the ejection assembly to extend or retract.

[0020] A foot pedal valve, the control end of which is connected to the ejection assembly to control the ejection assembly to retract.

[0021] The beneficial effects achievable by this invention are as follows: When the rotating positioning block is rotated to a certain positioning slot by manually rotating the annular turntable, the ejector mechanism ejects the rotating positioning block into the positioning slot. At the same time, the ejector mechanism contacts the contact point of the touch-sensitive mechanical control valve to open it, thereby causing the ejection component to push the locking positioning block into the corresponding other positioning slot, thus completing the fixation of the annular turntable. The foot valve is used to retract the pushing component, so that the locking positioning block cannot be fixed to the annular turntable. The rotating positioning block is connected to the annular turntable in a rotating and rolling manner, at which point the annular turntable can be pushed to rotate in any direction and at any angle.

[0022] The base includes a base and an annular support plate. The annular support plate is fixed on the base, and the annular turntable is rotatably connected to the outer ring wall of the annular support plate.

[0023] The positioning slot is arc-shaped, and both the locking positioning block and the rotating positioning block are cylindrical blocks that can be fitted and engaged with the arc-shaped slot.

[0024] The ejection assembly includes a cylinder, a first slide rail, and a push block. The cylinder is fixed to the top of the base. The first slide rail is arranged along the radial direction of the annular turntable and fixed to the top of the base. The push block is fixed to the piston rod of the cylinder and slides in cooperation with the first slide rail. The locking positioning block is fixed to the push block.

[0025] The ejection mechanism includes a fixed plate, a compression spring, a slider, and a second slide rail. The fixed plate is fixed to the top of the base. The compression spring is arranged in the radial direction of the annular turntable and one end of the spring is connected to the fixed plate. The slider is fixed to the other end of the spring. The second slide rail is fixed to the top of the base below the compression spring and is slidably connected to the slider. The touch-sensitive mechanical control valve is fixed to the top of the base and its input end abuts against the side of the slider away from the compression spring.

[0026] It also includes an air source, which supplies air to the cylinder through the touch-operated mechanical control valve to control the piston rod of the cylinder to extend, and supplies air to the cylinder through the foot pedal valve to control the piston rod of the cylinder to retract.

[0027] The pressure-sensitive mechanical control valve includes a first valve body, a first valve core spring, and a first valve core. The first valve body is fixed to the top of the base. The first valve body has a first valve core mounting hole, an air inlet, an air outlet, and a pressure relief port. The first valve core mounting hole is a blind hole, and its opening faces the slider. One end of the air inlet is connected to the first valve core mounting hole, and the other end is connected to the air source. One end of the air outlet is connected to the first valve core mounting hole, and the other end is connected to the rodless chamber of the cylinder. The first valve core spring is placed in the first valve core mounting hole. One end of the first valve core is slidably connected in the first valve core mounting hole and connected to the first valve core spring. The other end of the first valve core is the pressure-sensitive end, and its other end can extend outside the first valve core mounting hole and abut against the side of the slider away from the compression spring.

[0028] The first valve core has a first position and a second position. In the first position, the first valve core spring is extended, the air inlet is blocked by the first valve core, the air outlet is connected to the pressure relief port, the air source cannot supply air to the rodless chamber of the cylinder, and the rodless chamber of the cylinder can release air through the pressure relief port. In the second position, the first valve core spring is compressed, the air inlet is connected to the air outlet, and the air source supplies air to the rodless chamber of the cylinder.

[0029] The foot valve includes a base plate, a telescopic rod, a pedal, a pedal spring, and a valve body. The telescopic rod is fixed to the top center of the base plate. One end of the pedal is hinged to one side of the top of the base plate, and its bottom center is hinged to the top of the telescopic rod. The pedal spring is fixed to the other side of the top of the base plate, and its top end is connected to the bottom of the other end of the pedal. The valve body is fixed to the top of the base plate between the telescopic rod and the pedal spring, and its control end is connected to the pedal.

[0030] The valve body includes a second valve body, a second valve core spring, and a second valve core. The second valve body is fixed to the base plate, and a second valve core mounting hole is provided on the top of the second valve body. The side wall of the second valve body is provided with a compressed air inlet, a first working port, a second working port, a first vent port, and a second vent port, all of which are connected to the second valve core mounting hole. The compressed air inlet is connected to the air source. The first working port is connected to the rodless chamber of the cylinder, and the second working port is connected to the rod chamber of the cylinder. The second valve core mounting hole is a blind hole. The second valve core spring is placed in the second valve core mounting hole. The bottom end of the second valve core is connected to the second valve core spring, and the top end is connected to the bottom surface of the pedal. A first flow channel and a second flow channel are spaced apart along the axial direction on the side wall of the second valve core.

[0031] The second valve core has a first working position and a second working position. The first working position is when the pedal is not depressed, the first working port is connected to the compressed air inlet through the first flow channel, and the second working port is connected to the second vent port through the second flow channel. The air source supplies air to the rodless chamber of the cylinder. The second working position is when the pedal is depressed, the first working port is connected to the first vent port through the first flow channel, and the second working port is connected to the compressed air inlet through the second flow channel. The air source supplies air to the rod chamber of the cylinder.

[0032] It is also provided with multiple positioning posts for connecting the workpiece fixture to be tested. The workpiece fixture to be tested has multiple positioning holes at its bottom. The multiple positioning posts are arranged at intervals along the circumferential direction of the annular turntable and fixed on the top of the annular turntable. The positioning posts can be inserted into the positioning holes.

[0033] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a multi-angle indexing rotation detection device, which has the following beneficial effects:

[0034] 1. The ring turntable can be fixed by the cooperation of the positioning slot and the locking positioning block, so as to realize positioning detection at different angles.

[0035] 2. Through the cooperation of the ejection mechanism and the touch-sensitive mechanical control valve, the cylinder can be automatically controlled to push out, so as to achieve accurate positioning of the locking positioning block and the annular turntable.

[0036] 3. By controlling the retraction of the cylinder piston rod through the foot pedal valve, the annular turntable can be rotated in any direction and positioned at any angle.

[0037] 4. The rotating positioning block can rotate and roll with the annular turntable, reducing the friction when the annular turntable rotates, and can also smoothly disengage from the positioning slot under the rotation of the annular turntable.

[0062] Please see Figures 1-8 This invention discloses a multi-angle indexing rotation detection device, comprising:

[0063] Base 1;

[0064] An annular turntable 2 is rotatably mounted on the top of the base 1. Multiple positioning slots 21 are evenly opened on the inner ring wall of the annular turntable 2 along its circumferential direction.

[0065] The locking and positioning mechanism 3 includes an ejection component 31 and a locking and positioning block 32. The ejection component 31 is fixed on the top of the base 1 on the inner ring side of the corresponding annular turntable 2. The pushing direction of the ejection component 31 is arranged along the radial direction of the annular turntable 2. The locking and positioning block 32 is fixed on the ejection end of the ejection component 31 and is in rolling connection with the inner ring wall of the annular turntable 2.

[0066] The elastic positioning mechanism 4 includes an ejection mechanism 41 and a rotating positioning block 42. The ejection mechanism 41 is fixed on the top of the base 1 on the inner ring side of the corresponding annular turntable 2, and its ejection direction is arranged along the radial direction of the annular turntable 2. The rotating positioning block 42 is rotatably installed at the ejection end of the ejection mechanism 41 in the axial direction parallel to the annular turntable 2 and is in rolling connection with the inner ring wall of the annular turntable 2. The rotating positioning block 42 and the locking positioning block 32 can be respectively positioned and connected to any two positioning slots 21.

[0067] The touch-sensitive mechanical control valve 5 is fixed on the top of the base 1 and its touch end is in contact with the ejection end of the ejection mechanism 41. Its control end is connected to the ejection assembly 31 to control the ejection assembly 31 to eject.

[0068] Foot valve 6, the control end of foot valve 6 is connected to push-out assembly 31 to control the retraction of push-out assembly 31.

[0069] When using this device, the annular turntable 2 is manually rotated. When the rotating positioning block 42 rotates to a certain positioning slot 21, the ejection mechanism 41 ejects the rotating positioning block 42 into the positioning slot 21. At the same time, the ejection mechanism 41 triggers the touch-sensitive mechanical control valve 5 to open, controlling the push-out component 31 to push the locking positioning block 32 into the corresponding other positioning slot 21, thus completing the fixation of the annular turntable 2. The foot valve 6 is used to retract the push component 31, so that the locking positioning block 32 can no longer be fixed to the annular turntable 2. The rotating positioning block 42 is connected to the annular turntable 2 in a rotating and rolling manner. At this time, the annular turntable 2 can be pushed to rotate in any direction and at any angle.

[0070] The base 1 includes a base 11 and an annular support plate 12. The annular support plate 12 is fixed on the base 11, and the annular turntable 2 is rotatably connected to the outer ring wall of the annular support plate 12 through a bearing.

[0071] See Figures 1-3 The base 11 has multiple support components 9 at its bottom. Each support component 9 includes an adjusting screw 91, an adjusting nut 92, and a support plate 93. The adjusting screw 91 is threaded to the bottom of the base 11, and the adjusting nut 92 is threaded to the adjusting screw 91 below the corresponding base 11. The support plate 93 is installed at the bottom of the adjusting screw 91, which serves to fix and support the base 11.

[0072] See Figures 4-5 The positioning slot 21 is arc-shaped, and the rotating positioning block 42 is a cylindrical block that can be fitted and engaged with the arc-shaped slot. Under the action of the ejection mechanism, the rotating positioning block maintains contact with the inner ring wall of the annular turntable. While the rotating positioning block 42 is in rolling connection with the annular turntable 2, it can rotate itself to reduce the frictional resistance between it and the inner ring wall of the annular turntable 2. At the same time, when the ejection component 31 retracts and the annular turntable 2 rotates, the rotating positioning block 42 can smoothly disengage from the positioning slot 21.

[0073] The locking and positioning block 32 is also a cylindrical block that fits and engages with the arc-shaped slot, so that the locking and positioning block 32 can be tightly connected and positioned with the positioning slot 21.

[0074] The number of positioning slots 21 can be customized according to the needs of the inspection. For example, 4 notches, 8 notches, 12 notches can be made to meet the 90°, 45°, 30° and other angle division positioning.

[0075] The ejection assembly 31 includes a cylinder 311, a push block 312, and a first slide rail 313. The cylinder 311 is fixed to the top of the base 11. The first slide rail 313 is arranged along the radial direction of the annular turntable 2 and fixed to the top of the base 11. The push block 312 is fixed to the piston rod of the cylinder 311 and slides in cooperation with the first slide rail 313. The locking positioning block 32 is fixed to the push block 312. The movement of the piston rod of the cylinder 311 can push the push block 312, pushing or pushing the locking positioning block 32 from the positioning slot 21. The first slide rail 313 can ensure the direction of travel of the push block 312 and prevent the push block 312 from deviating.

[0076] The ejection mechanism 41 includes a fixed plate 411, a compression spring 412, a slider 413, and a second slide rail 414. The fixed plate 411 is fixed to the top of the base 11. The compression spring 412 is arranged in the radial direction of the annular turntable 2, and one end of it is connected to the fixed plate 411. The slider 413 is fixed to the other end of the spring. The second slide rail 414 is fixed to the top of the base 11 below the corresponding compression spring 412 and is slidably connected to the slider 413. The touch-sensitive mechanical control valve 5 is fixed to the top of the base 11, and its input end abuts against the side of the slider 413 away from the compression spring 412. The compression spring 412 drives the slider 413 to slide along the second slide rail 414, allowing the rotating positioning block 42 to rotate in or out of the positioning slot 21.

[0077] It is also equipped with an air source 10, which supplies air to the cylinder 311 through a touch-operated mechanical control valve 5 to control the piston rod of the cylinder 311 to extend, and supplies air to the cylinder 311 through a foot pedal valve 6 to control the piston rod of the cylinder 311 to retract.

[0078] See Figure 6 The touch-sensitive mechanical control valve 5 is a two-position three-way valve, and can be a mechanical control valve with model number VM132-M5-06A. The touch-sensitive mechanical control valve 5 includes at least a first valve body 51, a first valve core spring 52, and a first valve core 53. The first valve body 51 is fixed to the top of the base 11. The first valve body 51 has a first valve core mounting hole 511, an air inlet 512, an air outlet 513, and a pressure relief port 514. The first valve core mounting hole 511 is a blind hole, and its opening faces the slider 413. One end of the air inlet 512 is connected to the first valve core mounting hole 511, and the other end is connected to the air source 10. One end of the air outlet 513 is connected to the first valve core mounting hole 511, and the other end is connected to the rodless chamber of the cylinder 311. The first valve core spring 52 is placed inside the first valve core mounting hole 511. One end of the first valve core 53 is slidably connected inside the first valve core mounting hole 511 and connected to the first valve core spring 52. The other end of the first valve core 53 is a touch-sensitive end, and its other end can extend outside the first valve core mounting hole 511 and abut against the side of the slider away from the compression spring 412.

[0079] The first valve core 53 has a first position and a second position. In the first position, the first valve core spring 52 is extended, the air outlet 513 is connected to the pressure relief port 514, and the air source 10 cannot supply air to the rodless chamber of the cylinder 311. In the second position, the first valve core spring 52 is compressed, the air inlet 512 is connected to the air outlet 513, and the air source 10 supplies air to the rodless chamber of the cylinder 311.

[0080] For details, see Figure 6 A first annular flow channel 531 is formed on the middle side wall of the first valve core 53, and a second annular flow channel 532 is formed on the side wall of the first valve core 53 away from the first valve core spring 52. A first airflow channel 533 is formed at the second annular flow channel 532, arranged radially and communicating with it. A second airflow channel 534 is formed at the bottom of the first valve core 53, arranged axially. The second airflow channel 534 is a blind hole and communicates with the first airflow channel 531. An annular groove 515 is formed on the inner wall of the first valve core mounting hole 511 between its orifice and the air outlet 513. When the first valve core 53 is in the first position, the airflow flows along... Figure 6 The air flows in the direction indicated by the middle arrow. The air outlet 513 discharges the airflow in the rodless chamber of the cylinder sequentially through the annular groove 515, the second annular flow channel 532, the first airflow channel 533, and the second airflow channel 534 to the pressure relief port 514. When the first valve core 53 is in the second position, the airflow provided by the air source enters from the air inlet 512, passes through the first airflow channel 531, and enters the air outlet 513, supplying air to the rodless chamber of the cylinder 311.

[0081] like Figure 7 The foot valve 6 is a two-position five-way valve, which can be a foot valve of model XT34-67. Specifically, it includes a base plate 61, a telescopic rod 62, a pedal 63, a pedal spring 64, and a valve body 65. The telescopic rod 62 is fixed to the top center of the base plate 61. The bottom center of the pedal 63 is hinged to the top of the telescopic rod 62. The bottom end of the pedal spring 64 is fixed to one side of the top of the base plate 61, and the top end is connected to one side of the bottom of the pedal 63. The valve body 65 is fixed to the top of the base plate 61 between the telescopic rod 62 and the pedal spring 64, and its control end is connected to the pedal 63.

[0082] The valve body 65 includes a second valve body, a second valve core spring, and a second valve core. The second valve body is fixed on the base plate 61, and a second valve core mounting hole is provided on the top of the second valve body. The side wall of the second valve body is provided with a compressed air inlet, a first working port, a second working port, a first vent port, and a second vent port, all of which are connected to the second valve core mounting hole. The compressed air inlet is connected to the air source 10. The first working port is connected to the rodless chamber of the cylinder 311, and the second working port is connected to the rod chamber of the cylinder 311. The second valve core mounting hole is a blind hole. The second valve core spring is placed in the second valve core mounting hole. The bottom end of the second valve core is connected to the second valve core spring, and the top end is connected to the bottom surface of the pedal 63. A first flow channel and a second flow channel are spaced apart along the axial direction on the side wall of the second valve core.

[0083] The second valve core has a first working position and a second working position. In the first working position, the pedal 63 is not depressed. The first working port is connected to the compressed air inlet through the first flow channel, and the second working port is connected to the second vent port through the second flow channel. The air source 10 supplies air to the rodless chamber of the cylinder 311. In the second working position, the pedal 63 is depressed. The first working port is connected to the first vent port through the first flow channel, and the second working port is connected to the compressed air inlet through the second flow channel. The air source 10 supplies air to the rod chamber of the cylinder 311.

[0084] It is also provided with multiple positioning pins 8 for connecting the workpiece fixture 7 to be tested. Multiple positioning holes are opened at the bottom of the fixture 7. The multiple positioning pins 8 are arranged at intervals along the circumferential direction of the annular turntable 2 and fixed on the top of the annular turntable 2. The positioning pins 8 can be inserted into the positioning holes.

[0085] Working principle:

[0086] In use, the workpiece to be tested is fixed by a fixture 7, which is fixed to the annular turntable 2 by a positioning pin 8. The foot valve remains in its original position. The annular turntable 2 is rotated manually, and the rotating positioning block 42 rotates to a certain positioning slot 21. The ejection mechanism 41 ejects the rotating positioning block 42 into the positioning slot 21. At this time, the slider 413 presses the first valve core 53 of the touch-type mechanical control valve 5, so that the first valve core 53 is in the second position. The air source 10 supplies air to the rodless chamber of the cylinder 311, pushing the piston rod of the cylinder 311 out and pushing the locking positioning block 32 into its corresponding positioning slot 21, thus completing the positioning of the annular turntable 2. A certain surface to be tested corresponding to the workpiece can be inspected.

[0087] After the test is completed, step on the foot valve 6 to put the second valve core in the second working position. The air source 10 supplies air to the rod chamber of the cylinder 311 through the foot valve 6, and the rodless chamber of the cylinder releases air through the first vent of the foot valve 6, causing the cylinder piston rod to retract. The locking positioning block 32 disengages from the positioning slot 21, and the annular turntable 2 can continue to rotate. As the annular turntable 2 continues to rotate, release the foot valve 6. When it rotates to the next positioning slot 21, the touch-sensitive mechanical control valve 5 continues to drive the cylinder piston rod out under the touch of the ejection mechanism 4 to perform positioning at the next angle.

[0088] During testing, if the annular turntable 2 needs to be rotated at any angle, that is, when it reaches the positioning slot 21, the locking positioning block 32 does not need to be locked. In this case, the foot pedal valve 6 can be kept pressed. Even if the rotating positioning block 42 enters the positioning slot 21 when it reaches the positioning slot, the touch-sensitive mechanical control valve 5 is pressed by the ejection mechanism 4. However, since the second valve core of the foot pedal valve 6 is in the second working position at this time, even if the air source supplies air to the rodless chamber of the cylinder 311 through the touch-sensitive mechanical control valve 5, the cylinder 311 will not move, the piston rod will not extend, and the locking positioning block 32 cannot lock and position. The rotating positioning block 42 can continue to rotate out of the positioning slot 21 until the annular turntable 2 needs to be locked. Then, the foot pedal valve 6 is released, and the locking positioning block 32 can lock and position with the positioning slot 21 under the action of the touch-sensitive mechanical control valve 5.

[0089] The annular turntable 2 of this device can rotate in any direction and be positioned at any angle. This device can realize the rotation of the workpiece under test in any direction and at any angle, which is convenient for manual inspection and observation of any position of the workpiece under test. At the same time, there is no need for the intervention of a motor or other power source, which is convenient for manual operation, low cost and easy maintenance.

[0090] This invention can be used in scenarios such as inspection, observation, deburring, cleaning, and assembly of multiple surfaces of any part to assist manual operations; such as the inspection, assembly, and loading of industrial control valves.
