Description

Technical Field

[0001] This invention relates to the field of processing equipment technology, and in particular to a positioning device for cylinder bottom and cylinder bottom processing equipment. Background Technology

[0002] The cylinder bottom, as the connecting component between the cylinder and other parts, requires high strength and machining accuracy, and is often machined from forged blanks.

[0003] Due to the irregular shape of the forging blank and the random placement angle, the robot is guided to grasp it using devices such as vision cameras. However, due to the imaging error of the vision camera and the sliding of the forging blank during the grasping process, there will be accuracy errors. It is impossible to accurately determine the position and angle of the forging blank, which will cause it to collide with the machine tool fixture during the loading and unloading process.

[0004] In existing technologies, operators typically need to manually pick up the forging blank, adjust its position or angle, and then place it on the processing device. This is not conducive to the advancement of fully automated processing, resulting in low production efficiency, high labor intensity, and high operational risks.

[0005] Therefore, how to solve the problem of large manual operation caused by the inability to accurately and automatically identify the position and angle of the forging blank when machining the bottom of the hydraulic cylinder has become an important technical problem to be solved by those skilled in the art. Summary of the Invention

In the releasing position, the projection area of ​​the clamping member along the axial direction of the positioning post is outside the projection area of ​​the positioning post along its own axial direction.

[0016] The second drive assembly is adapted to drive the clamping member to move between the clamping position and the releasing position.

[0017] According to the present invention, a positioning device for the bottom of a cylinder includes an adjustment mechanism comprising:

[0018] A pair of adjusting arms are slidably connected to the base. The pair of adjusting arms can move closer to or further away from each other. The distribution direction of the pair of adjusting arms is perpendicular to the target direction of the axis of the cylinder bottom forging.

[0019] A first drive assembly is adapted to drive the adjusting arm to slide relative to the base.

[0020] According to the positioning device for the cylinder bottom provided by the present invention, the first drive assembly includes:

[0021] A double piston cylinder is disposed between a pair of adjusting arms. The cylinder body of the double piston cylinder is fixedly connected to the base, and the two piston rods of the double piston cylinder are respectively connected to a pair of adjusting arms.

[0022] According to the present invention, a positioning device for a cylinder bottom is provided, wherein the adjusting arm comprises:

[0023] An adjusting arm body extends in a direction away from the base, and a first end of the adjusting arm body is slidably connected to the base;

[0024] An action block is fixedly disposed at the second end of the adjusting arm body. The side of the action block facing the other adjusting arm is in the shape of a V-shaped surface or a cylindrical surface. The axis of the V-shaped surface or the cylindrical surface is parallel to the target direction of the axis of the cylinder bottom forging.

[0025] A positioning device for the bottom of a cylinder according to the present invention further includes:

[0026] A leveling mechanism is provided on the base, and the leveling mechanism is adapted to adjust the levelness of the bearing surface of the base.

[0027] A positioning device for the bottom of a cylinder according to the present invention further includes:

[0028] A collection tray is disposed on the base, and the collection tray is located below the positioning mechanism and the adjustment mechanism. The collection tray is adapted to collect debris attached to the cylinder bottom forging.

[0029] According to the present invention, a positioning device for a cylinder bottom is provided, wherein the base comprises:

[0030] Lower base;

[0031] An upper base is disposed above the lower base, a collection tray is disposed between the upper base and the lower base, and a positioning mechanism and an adjustment mechanism are disposed on the upper base;

The positioning mechanism also allows the cylinder bottom forging to rotate relative to the positioning mechanism about the axis of the lug portion. The adjusting mechanism is movably disposed on the base and has a target position. The adjusting mechanism interacts with the bottom of the cylinder bottom forging.

Moreover, when the robot grasps the cylinder bottom forging on the positioning device provided by this invention, the positioning mechanism and adjustment mechanism can restrict the sliding of the cylinder bottom forging, ensuring that the robot accurately grasps the cylinder bottom forging and transfers it to the processing device. This effectively avoids the problem of the cylinder bottom forging sliding during the grasping process, thereby avoiding the problem of the cylinder bottom forging colliding with machine tool fixtures during loading and unloading. It avoids manual operation, promotes the advancement of fully automated processing, improves production efficiency, reduces labor intensity and operational risks, and solves the problem of large amount of manual operation caused by the inability to accurately and automatically identify the position and angle of the forging blank when processing the cylinder bottom of the hydraulic cylinder in the prior art.

[0047] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0048] The following is combined with Figures 1 to 8 The present invention describes a positioning device for the bottom of a cylinder.

[0049] like Figures 1 to 8 As shown, the positioning device for the cylinder bottom provided in this embodiment of the invention is used to be disposed on one side of the processing device and to adjust the position and angle of the cylinder bottom forging 1 before placing the cylinder bottom forging 1 on the processing device.

[0050] The cylinder bottom forging 1 includes an ear ring portion 3 and a cylinder bottom portion 2. The ear ring portion 3 is annular, and the cylinder bottom portion 2 is disc-shaped. The plane containing the ear ring portion 3 is perpendicular to the cylinder bottom portion 2. (Refer to...) Figure 7 and Figure 8 When machining the cylinder bottom forging 1, it needs to be processed at different workstations in sequence. Specifically, the cylinder bottom 2 away from the lug part 3 needs to be machined, countersunk, and drilled on a lathe first time; then the lug part 3 needs to be milled, bored, milled on the side, drilled, and drilled on the side on a milling machine to form the finished part.

[0051] The positioning devices for the cylinder bottom provided in this embodiment can be respectively installed on one side of the lathe and one side of the milling machine. When machining the cylinder bottom forging 1, a robot first places the cylinder bottom forging 1 on the positioning device for the cylinder bottom on one side of the lathe. After adjusting and positioning the position and angle of the cylinder bottom forging 1 using the positioning device for the cylinder bottom, the robot then transfers the cylinder bottom forging 1 from the positioning device for the cylinder bottom to the fixture of the lathe. After machining on the lathe, the robot first transfers the cylinder bottom forging 1 from the lathe to the positioning device for the cylinder bottom on the side of the milling machine. After adjusting and positioning the position and angle of the cylinder bottom forging 1 using the positioning device for the cylinder bottom, the robot then transfers the cylinder bottom forging 1 from the positioning device for the cylinder bottom to the milling machine.

[0052] The positioning device for the cylinder bottom provided in this embodiment of the invention includes a base, a positioning mechanism, and an adjustment mechanism.

[0053] Specifically, the base has a horizontal bearing surface for supporting the positioning and adjustment mechanisms.

[0054] The positioning mechanism is mounted on the bearing surface of the base. The positioning mechanism interacts with the lug portion 3 of the cylinder bottom forging 1. Through this interaction, the cylinder bottom forging 1 can be positioned. The positioning mechanism also allows the cylinder bottom forging 1 to rotate relative to the positioning mechanism about the axis of the lug portion 3.

[0055] The adjustment mechanism is movably mounted on the bearing surface of the base and has a target position. The adjustment mechanism can interact with the cylinder bottom 2 of the cylinder bottom forging 1. When the adjustment mechanism moves towards the target position, the interaction between the adjustment mechanism and the cylinder bottom 2 can push the cylinder bottom forging 1 to rotate relative to the positioning mechanism about the axis of the ear ring portion 3.

[0056] When the adjustment mechanism is in the target position, the position of the axis of the cylinder bottom forging 1 is consistent with the target position of the axis of the cylinder bottom forging 1, thus completing the adjustment of the position angle of the cylinder bottom forging 1.

[0057] With this configuration, before placing the cylinder bottom forging 1 onto the processing device, the positioning device for the cylinder bottom provided by this invention can adjust the position and angle of the cylinder bottom forging 1. Furthermore, when the robot grips the cylinder bottom forging 1 on the positioning device provided by this invention, the positioning mechanism and adjustment mechanism can restrict the sliding of the cylinder bottom forging 1, ensuring that the robot accurately grips the cylinder bottom forging 1 in a stable posture and transfers it to the processing device. This effectively avoids the problem of the cylinder bottom forging 1 sliding during gripping, thereby preventing collisions between the cylinder bottom forging 1 and machine tool fixtures during loading and unloading. It eliminates the need for manual operation, facilitates the advancement of fully automated processing, improves production efficiency, reduces labor intensity and operational risks, and solves the problem of excessive manual operation in the prior art when processing the cylinder bottom of hydraulic cylinders due to the inability to accurately and automatically identify the position and angle of the forging blank.

[0058] In this embodiment of the invention, the positioning mechanism includes a positioning post 4 and a support part 5.

[0059] The positioning post 4 is fixedly installed on the base, and the axis of the positioning post 4 is perpendicular to the bearing surface of the base. In other words, the axis of the positioning post 4 is set in the vertical direction.

[0060] The positioning post 4 has a circular cross-section, and its outer diameter gradually decreases away from the base. Therefore, the positioning post 4 is truncated cone-shaped. Figure 3 The positioning pin 4 has a large end and a small end, with the large end connected to the base. When the cylinder bottom forging 1 is placed in the positioning mechanism, the small end of the positioning pin 4 enters the ear ring part 3 first, reducing the difficulty of placing the cylinder bottom forging 1 in the positioning mechanism. Moreover, since the cylinder bottom forging 1 is a blank, the dimensional accuracy of the ear ring part 3 is relatively poor, and the ear ring part 3 of the cylinder bottom forging 1 generally has a draft taper of about 3°, the frustum-shaped positioning pin 4 has strong adaptability.

[0061] Three support parts 5 are provided, and the three support parts 5 are distributed at intervals along the circumference of the positioning post 4. The three support parts 5 together support the earring part 3. By utilizing the principle of three-point plane positioning, it is possible to ensure stable support for the earring part 3 and improve the positioning accuracy of the earring part 3.

[0062] A first fixing seat 17 is provided on the base for fixing the positioning post 4. The support part 5 is configured as a columnar structure, the axis of the support part 5 is parallel to the axis of the positioning post 4, the first end of the support part 5 is fixedly connected to the positioning post 4, the second ends of the three support parts 5 are coplanar, and the plane is perpendicular to the axis of the positioning post 4.

[0063] The positioning pin 4 can be detachably connected to the first fixed seat 17. By replacing the positioning pin 4 with different sizes, the positioning of the cylinder bottom forging 1 of different sizes can be achieved.

[0064] When the cylinder bottom forging 1 is rotated relative to the positioning column 4 using the adjustment mechanism, in order to ensure the stability of the cylinder bottom forging 1, the positioning mechanism in this embodiment also includes a clamping member 6 and a second drive assembly 7.

[0065] The clamping element 6 is movably mounted on the base, and the clamping element 6 is located on the side of the positioning post 4 away from the adjustment mechanism, so as to avoid interference between the clamping element 6 and the adjustment mechanism.

[0066] The clamping member 6 is movable between a clamping position and a releasing position, and the second drive assembly 7 is used to drive the clamping member 6 to move between the clamping position and the releasing position.

[0067] When the clamping member 6 moves to the clamping position, it is located on the side of the positioning post 4 away from the base, and directly opposite the end of the positioning post 4 away from the base. When the ear loop portion 3 of the cylinder bottom forging 1 is fitted onto the positioning post 4, the clamping member 6 can contact the ear loop portion 3. Through the interaction between the clamping member 6 and the ear loop portion 3, when the cylinder bottom forging 1 rotates relative to the positioning post 4, the movement of the ear loop portion 3 can be reduced, ensuring the stability of the ear loop portion 3.

[0068] When the clamping member 6 moves to the release position, the clamping member 6 is located on the side of the positioning post 4 away from the base, and the projection area of ​​the clamping member 6 along the axial direction of the positioning post 4 is outside the projection area of ​​the positioning post 4 along its own axial direction. The clamping member 6 is offset from the lug portion 3 of the cylinder bottom forging 1, which allows the cylinder bottom forging 1 to be removed from the positioning post 4.

[0069] Specifically, the second drive assembly 7 includes a swing cylinder, whose piston rod can rotate relative to the cylinder while extending and retracting from the cylinder. The cylinder of the swing cylinder is fixed to the base, and the piston rod of the swing cylinder is fixedly connected to the clamping member 6.

[0070] To reduce the requirements on the extension and retraction of the piston rod of the swing cylinder, the swing cylinder can be mounted on the second fixed seat 18, as shown in the reference. Figure 1 , Figure 2 and Figure 4 .

[0071] To reduce the impact of the clamping component 6 on the cylinder bottom forging 1, a buffer pad is provided on the side of the clamping component 6 near the positioning post 4. The material of the buffer pad can be, but is not limited to, rubber or silicone.

[0072] In this embodiment of the invention, the adjustment mechanism includes an adjustment arm 8 and a first drive assembly.

[0073] A pair of adjusting arms 8 are provided, and the adjusting arms 8 are slidably connected to the base. The sliding direction of the adjusting arms 8 relative to the base is parallel to the distribution direction of the pair of adjusting arms 8, so that the pair of adjusting arms 8 can move closer to or further away from each other. The first drive assembly is used to drive the adjusting arms 8 to slide relative to the base.

[0074] A pair of adjusting arms 8 are located on one side of the positioning mechanism, and the distribution direction of the pair of adjusting arms 8 is perpendicular to the target direction of the axis of the cylinder bottom forging 1. When the adjusting mechanism is in the target position, the pair of adjusting arms 8 cooperate to clamp the cylinder bottom 2 of the cylinder bottom forging 1.

[0075] When placing the cylinder bottom forging 1 on the positioning device for the cylinder bottom provided in this embodiment, it is necessary not only to move the clamping member 6 to the release position, but also to slide the adjusting arm 8 to the position where the distance between the pair of adjusting arms 8 is the largest. At this time, the distance between the pair of adjusting arms 8 is large, which can ensure that the cylinder bottom forging 1 can be smoothly placed on the base.

[0076] In this embodiment, the first driving assembly includes a double piston cylinder 9, which is disposed between a pair of adjusting arms 8, and the axis of the double piston cylinder 9 is parallel to the distribution direction of the pair of adjusting arms 8. The cylinder body of the double piston cylinder 9 is fixedly connected to the base, and the two piston rods of the double piston cylinder 9 are respectively connected to the pair of adjusting arms 8.

[0077] When the dual-piston cylinder 9 is in operation, a pair of adjusting arms 8 can slide simultaneously. At this time, the pair of adjusting arms 8 can be symmetrically arranged on both sides of the target direction of the axis of the cylinder bottom forging 1.

[0078] Both the first drive assembly and the second drive assembly 7 are configured to resemble cylinders. Therefore, the positioning device for the cylinder bottom in this embodiment of the invention also includes a pneumatic triplet, a solenoid valve, an air pump, and other pneumatic systems to provide power to the double piston cylinder 9 and the swing cylinder.

[0079] In this embodiment, the adjusting arm 8 includes an adjusting arm body 16 and an action block 10.

[0080] The adjusting arm body 16 extends away from the base, and its first end is slidably connected to the base. The second end of the adjusting arm body 16 has an extension that extends towards another adjusting arm body 16, as shown in the figure. Figure 5 The second end of the adjusting arm body 16 has a bending structure.

[0081] The action block 10 is fixedly installed at the second end of the adjusting arm body 16. The side of the action block 10 facing the other adjusting arm 8 is in the shape of a V-shaped surface or a cylindrical surface, and the axis of the V-shaped surface or cylindrical surface is parallel to the target direction of the axis of the cylinder bottom forging 1.

[0082] The action block 10 is in line contact with the cylinder bottom 2 of the cylinder bottom forging 1. The contact line extends along the axis of the cylinder bottom forging 1. When the adjusting arm 8 pushes the cylinder bottom forging 1, it can ensure that the cylinder bottom forging 1 is subjected to uniform force.

[0083] Moreover, the force exerted by the V-shaped or cylindrical surface on the cylinder bottom forging 1 has not only a clamping component in the horizontal direction, but also a supporting component in the vertical direction, which can improve the clamping effect of the adjustment mechanism on the cylinder bottom forging 1.

[0084] The actuating block 10 can be detachably connected to the adjusting arm 8. By replacing the actuating block 10 with different sizes, the positioning of cylinder bottom forgings 1 of different sizes can be achieved. Here, when the side of the actuating block 10 facing the other adjusting arm 8 is a V-shaped surface, the included angle of the V-shaped surface of the actuating block 10 with different sizes is different; when the side of the actuating block 10 facing the other adjusting arm 8 is a cylindrical surface, the diameter of the cylindrical surface of the actuating block 10 with different sizes is different.

[0085] The dual piston cylinder 9 can also be detachably connected to the base. By installing the dual piston cylinder 9 at different positions on the base, the distance between the adjusting arm 8 and the positioning column 4 can be adjusted, thereby enabling the positioning of cylinder bottom forgings 1 of different lengths.

[0086] Alternatively, a connecting block can be provided between each piston rod of the dual-piston cylinder 9 and the adjusting arm 8. The connecting block has multiple connection positions that connect to the adjusting arm 8, and the distribution direction of the multiple connection positions is horizontal and perpendicular to the axial direction of the dual-piston cylinder 9. By connecting the adjusting arm 8 to different connection positions of the connecting block, the distance between the adjusting arm 8 and the positioning post 4 can be adjusted, thereby enabling the positioning of cylinder bottom forgings 1 of different lengths.

[0087] In this embodiment of the invention, the positioning device for the cylinder bottom further includes a leveling mechanism, which is disposed at the lower end of the base and is used to adjust the levelness of the bearing surface of the base.

[0088] In a specific embodiment, the leveling mechanism includes a plurality of adjusting feet 15, which are distributed at intervals along the circumference of the base.

[0089] In this embodiment of the invention, the positioning device for the cylinder bottom further includes a collection tray 11, which is disposed on the base and located below the positioning mechanism and the adjustment mechanism.

[0090] After the cylinder bottom forging 1 is processed once, water, oil, iron filings and other debris will be attached to the surface of the cylinder bottom forging 1. After the cylinder bottom forging 1 is placed on the positioning device for the cylinder bottom provided in this embodiment, the collection tray 11 can collect the debris that falls from the cylinder bottom forging 1, ensuring the cleanliness of the processing device area.

[0091] In this embodiment, the base includes an upper base 13, a lower base 12, and a support member 14. The upper base 13 is disposed above the lower base 12, and a collection tray 11 is disposed between the upper base 13 and the lower base 12. The positioning mechanism and the adjustment mechanism are disposed on the upper base 13. The edge of the collection tray 11 extends beyond the area where the upper base 13, the positioning mechanism, and the adjustment mechanism are located, ensuring the collection range and collection effect of the collection tray 11.

[0092] The support member 14 is disposed between the collection tray 11 and the upper base 13 to separate the upper base 13 from the collection tray 11, forming a certain space between the upper base 13 and the collection tray 11, which facilitates the cleaning of the positioning device used at the bottom of the cylinder.

[0093] Multiple support members 14 are provided, and the multiple support members 14 are distributed at intervals along the circumference of the upper base 13, which can improve the stability of the upper base 13.

[0094] In this embodiment of the invention, the positioning device for the cylinder bottom further includes a first detection element 19, a second detection element, and a control system.

[0095] The first detection element 19 is used to detect the contact state between the earring part 3 and the support part 5, so as to determine whether the cylinder bottom forging 1 exists on the positioning mechanism or whether the cylinder bottom forging 1 is placed in place. The first detection element 19 can be a contact sensor and is set on the first fixed base 17.

[0096] The second detection element is used to detect the position of the adjusting arm 8 to determine whether the adjusting mechanism has properly adjusted the position and angle of the cylinder bottom forging 1. The second detection element can be a cylinder stroke sensor.

[0097] The first detection element 19, the second detection element, the first drive assembly, and the second drive assembly 7 are all electrically connected to the control system, which can realize the automated positioning of the cylinder bottom forging 1.

[0098] The robot used to transfer the cylinder bottom forging 1 can also be electrically connected to the control system to further improve the level of automation.

[0099] In summary, the positioning device for the cylinder bottom provided in this embodiment of the invention can achieve precise positioning and high flexibility. It can switch between different sizes of positioning pins 4 and adjust the distance between the adjusting arm 8 and the positioning pins 4 according to the size of the lug part 3 of the cylinder bottom forging 1 and the overall length of the cylinder bottom forging 1, thus exhibiting strong adaptability.

[0100] Furthermore, the positioning device for the cylinder bottom provided in this embodiment of the invention allows the robot to use its external gripper fingers to grasp the cylinder bottom 2 of the cylinder bottom forging 1, and also allows the robot to use its internal gripper hand to grasp the ear loop portion 3 of the cylinder bottom forging 1. This allows the robot to freely change its gripping position, adapts to multi-process loading and unloading, and is highly versatile.

[0101] The positioning device for the cylinder bottom provided in this embodiment of the invention uses common parts available on the market, has a simple structure, good positioning effect, and strong applicability.

[0102] On the other hand, embodiments of the present invention also provide a cylinder bottom processing apparatus, including a processing device, a transfer device, and a positioning device for the cylinder bottom provided in any of the above embodiments. The positioning device is disposed on one side of the processing device and is used to automatically adjust the position angle of the cylinder bottom forging. The processing device is used to process the cylinder bottom forging, and the transfer device is used to transfer the cylinder bottom forging to the positioning device and transfer the cylinder bottom forging on the positioning device to the processing device.

[0103] The positioning device for the cylinder bottom provided in the above embodiments can accurately and automatically position the cylinder bottom forging, ensuring that the robot accurately grasps the cylinder bottom forging 1 and transfers it to the processing device. This effectively avoids the problem of the cylinder bottom forging 1 sliding during the grasping process, thereby avoiding the problem of the cylinder bottom forging 1 colliding with the machine tool fixtures during the loading and unloading process. It avoids manual operation, which is conducive to the advancement of fully automated processing, improves production efficiency, and reduces labor intensity and operational risks.

[0104] Therefore, the cylinder bottom processing equipment in this embodiment has the advantages of high automation and high reliability, and can operate smoothly. The derivation process of the beneficial effects of the cylinder bottom processing equipment in this embodiment is largely similar to the derivation process of the beneficial effects of the positioning device for the cylinder bottom described above, so it will not be repeated here.

[0105] The cylinder bottom processing equipment provided in this embodiment of the invention includes two processing devices, namely a first processing device and a second processing device, and a positioning device for the cylinder bottom provided in the above embodiment is respectively arranged on one side of the first processing device and one side of the second processing device.

[0106] The first working device is a lathe, the second working device is a milling machine, and the transfer device is a robot.

[0107] The cylinder bottom processing equipment provided in this embodiment of the invention has two processes during processing, and the loading and unloading process of each process is as follows:

[0108] Guided by the vision device, the robot picks up the cylinder bottom forging 1 from the material tray and places the cylinder bottom forging 1 on the positioning device for the cylinder bottom, so that the ear ring part 3 of the cylinder bottom forging 1 cooperates with the positioning post 4.

[0109] Switch the clamping part 6 to the clamping position so that the clamping part 6 is pressed against the ear ring part 3 of the cylinder bottom forging 1;

[0110] After the first detection element 19 detects that the ear ring part 3 of the cylinder bottom forging 1 is placed in place, it controls the adjusting arms 8 to move closer to each other in order to adjust the direction of the axis of the cylinder bottom forging 1.

[0111] After the second detection element detects that the adjusting arm 8 has moved into place, the robot grabs the cylinder bottom forging 1 from the positioning device for the cylinder bottom.
