Description

Technical Field

[0001] This utility model relates to the field of clamping equipment technology, and in particular to a clamping device. Background Technology

[0002] Nowadays, during workpiece processing, clamping equipment typically uses two drive components to drive two clamping components to move relative to each other in order to clamp the workpiece.

[0003] However, the two drive components occupy a large space, which will obscure part of the workpiece's structure, making it more difficult to process parts of the workpiece's structure, and the cost of using the two drive components is high. Utility Model Content

[0004] In view of the above situation, it is necessary to provide a clamping device to optimize the layout and reduce the cost of use.

[0005] This application provides a clamping device, including: Base; A clamping assembly includes a first gripper, a second gripper, and two elastic members. The first gripper and the second gripper are disposed opposite to each other and are slidably connected to the base. One of the elastic members is connected to both the base and the first gripper, and the other elastic member is connected to both the base and the second gripper. A driving assembly includes a driving component, a linkage component, and a pushing component. The driving component is disposed on the base. The linkage component is connected to the driving component and the first gripper, respectively. The linkage component is configured to drive the first gripper to move closer to the second gripper under the drive of the driving component. The pushing component is slidably connected to the base in a direction perpendicular to the movement direction of the second gripper. The pushing component abuts against the linkage component and the second gripper, respectively, and is used to push the second gripper under the push of the linkage component, so that the second gripper and the first gripper move synchronously relative to each other to clamp the workpiece.

[0006] When the aforementioned clamping device clamps a workpiece, the linkage, driven by the drive unit, moves the first gripper closer to the second gripper and pushes the abutment to move, causing the abutment to push against the second gripper. This allows the first and second grippers to move synchronously relative to each other to clamp the workpiece. Simultaneously, the first and second grippers compress their corresponding elastic elements to the base. When releasing the workpiece, the drive unit cancels the drive of the linkage to move the first gripper. The two elastic elements provide elastic force to drive the first and second grippers to move synchronously in opposite directions to release the workpiece. Thus, the clamping device, through the drive unit driving the linkage to push the abutment, causes the first and second grippers to move synchronously relative to each other to clamp the workpiece. This allows for clamping operations using a single drive source, avoiding obstruction of the workpiece for easier processing, optimizing the layout, and preventing the use of too many drive sources for clamping operations, thereby reducing operating costs.

[0007] In some embodiments, both the first gripper and the second gripper include: A sliding body is slidably connected to the base along the movement direction of the first gripper; the sliding body is connected to the corresponding elastic element; and the sliding body of the first gripper is connected to the linkage element. A clamping body is perpendicularly connected to the sliding body, and the clamping body of the second gripper abuts against the pushing member, the clamping body being configured to abut against the workpiece.

[0008] In some embodiments, both the first gripper and the second gripper further include: A support body is located at the end of the clamping body away from the sliding body and is perpendicularly connected to the clamping body. The support body is configured to support the workpiece.

[0009] In some embodiments, the support body has an elastic positioning portion on the side facing the base, the elastic positioning portion being configured to elastically abut the workpiece against the base.

The substrate is also connected to the two elastic members, respectively. The substrate is provided with a through hole. A support member is disposed on one side of the substrate and connected to the substrate and the drive member respectively, and the support member is configured to support the drive member.

[0012] In some embodiments, the linkage includes: A linkage body, one end of which is connected to the first gripper, and the other end of which abuts against the pusher; A connecting body protrudes from the side wall of the linkage body and is connected to the driving member. The connecting body is configured to drive the linkage body to push the pushing member under the drive of the driving member.

[0013] In some embodiments, the linkage body has a pushing part at one end near the pushing member. The pushing part is inclined relative to the movement direction of the second gripper. The pushing part abuts against the pushing member and is configured to push the pushing member.

[0014] In some embodiments, the pushing member includes: The movable body is slidably connected to the base in a direction perpendicular to the direction of movement of the second gripper; A rolling element is disposed at one end of the movable body near the linkage and rotatably connected to the movable body.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0022] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0023] Please see Figure 1 This application provides a clamping device 100, which includes a base 10, a clamping component 20 and a driving component 30. The clamping device 100 is used to clamp a workpiece.

[0024] Please see Figure 1The clamping assembly 20 includes a first gripper 21, a second gripper 22, and two elastic members 23. The first gripper 21 and the second gripper 22 are disposed opposite to each other and are slidably connected to the base 10. One elastic member 23 is connected to both the base 10 and the first gripper 21, and the other elastic member 23 is connected to both the base 10 and the second gripper 22. The driving assembly 30 includes a driving member 31, a linkage member 32, and a pushing member 33. A driving member 31 is disposed on the base 10. A linkage member 32 is connected to the driving member 31 and the first gripper 21 respectively. The linkage member 32 is configured to drive the first gripper 21 to move closer to the second gripper 22 under the drive of the driving member 31. A pushing member 33 is slidably connected to the base 10 in the direction perpendicular to the movement direction of the second gripper 22. The pushing member 33 abuts against the linkage member 32 and the second gripper 22 respectively, and is used to push the second gripper 22 under the push of the linkage member 32, so that the second gripper 22 and the first gripper 21 move synchronously relative to each other to clamp the workpiece. For example, the elastic member 23 can be a spring, and the driving member 31 can be a cylinder.

[0025] When the clamping device 100 clamps a workpiece, the linkage 32, driven by the drive member 31, moves the first gripper 21 closer to the second gripper 22 and pushes the pusher 33 to move, so that the pusher 33 pushes the second gripper 22, causing the first gripper 21 and the second gripper 22 to move synchronously relative to each other to clamp the workpiece. At the same time, the first gripper 21 and the second gripper 22 respectively compress the corresponding elastic members 23 to the base 10. When the clamping device 100 releases the workpiece, the drive member 31 cancels the drive of the linkage 32 to move the first gripper 21, and the two elastic members 23 provide elastic force to drive the first gripper 21 and the second gripper 22 to move synchronously in opposite directions to release the workpiece.

[0026] Thus, the clamping device 100 drives the linkage 32 to push the pusher 33 through the drive member 31, so that the first gripper 21 and the second gripper 22 move synchronously relative to each other to clamp the workpiece. This enables the clamping operation to be completed using a single drive source, avoids obstructing the workpiece so as to facilitate the processing of the clamped workpiece, thereby optimizing the layout and preventing the use of too many drive sources to complete the clamping operation, thereby reducing the cost of use.

[0027] Please see Figure 1 and Figure 2 In some embodiments, both the first gripper 21 and the second gripper 22 include a sliding body 221 and a clamping body 222. The sliding body 221 is slidably connected to the base 10 along the movement direction of the first gripper 21, and is connected to a corresponding elastic member 23. The sliding body 221 of the first gripper 21 is connected to the linkage member 32. The clamping body 222 is perpendicularly connected to the sliding body 221, and the clamping body 222 of the second gripper 22 abuts against the pushing member 33. The clamping body 222 is configured to abut against the workpiece.

[0028] Thus, through the above configuration, the sliding body 221 and the clamping body 222 are vertically connected, which optimizes the structure of the first clamping jaw 21 and the second clamping jaw 22, reduces the space occupancy rate of the first clamping jaw 21 and the second clamping jaw 22, and ensures that the sliding body 221 stably drives the clamping body 222 to hold the workpiece, thereby improving the clamping stability.

[0029] Please see Figure 2 In some embodiments, both the first gripper 21 and the second gripper 22 further include a support body 223. The support body 223 is located at the end of the clamping body 222 away from the sliding body 221 and is perpendicularly connected to the clamping body 222. The support body 223 is configured to support the workpiece.

[0030] Thus, through the above-mentioned arrangement, the support body 223 can support the bottom of the workpiece to prevent the workpiece from shaking or shifting significantly during the clamping process, thereby ensuring that the first jaw 21 and the second jaw 22 can stably clamp the workpiece and thus improving the clamping stability.

[0031] Please see Figure 1 and Figure 2 In some embodiments, the support 223 has an elastic positioning portion 2231 on the side facing the base 10, and the elastic positioning portion 2231 is configured to elastically hold the workpiece against the base 10. Exemplarily, the elastic positioning portion 2231 can be any positioning ball, positioning element, or positioning part capable of elastically holding the workpiece against the base 10, such as a steel ball connected to a spring.

[0032] Thus, through the above arrangement, the elastic positioning part 2231 can elastically hold the workpiece against the base 10 to position the workpiece in the direction from the base 10 to the support 223, thereby further improving the positioning stability.

[0033] Please see Figure 1 and Figure 2 In some embodiments, the clamping body 222 of the second gripper 22 includes a clamping portion 2221 and a rotating portion 2222. The clamping portion 2221 is perpendicularly connected to the sliding body 221 of the second gripper 22, and the rotating portion 2222 is disposed at one end of the clamping portion 2221 near the sliding body 221 of the second gripper 22 and is rotatably connected to the clamping portion 2221. The rotating portion 2222 abuts against the pushing member 33.

[0034] Thus, through the above arrangement, the second gripper 22 can form a rolling contact with the pushing member 33 through the rotating part 2222, thereby reducing the friction between the pushing member 33 and the second gripper 22, which is conducive to the smooth pushing of the second gripper 22 by the pushing member 33, thereby improving the clamping stability.

[0035] Please see Figure 1In some embodiments, the base 10 includes a base plate 11 and a support member 12. The base plate 11 is slidably connected to the first gripper 21, the second gripper 22, and the pusher 33, respectively. The base plate 11 is connected to two elastic members 23, respectively. The base plate 11 has a through hole 111. The support member 12 is disposed on one side of the base plate 11 and is connected to the base plate 11 and the drive member 31, respectively. The support member 12 is configured to support the drive member 31.

[0036] Thus, through the above arrangement, the through hole 111 can provide a larger processing space for the workpiece, making it easier for external processing equipment to process the clamped workpiece. At the same time, the drive member 31 is set on the support member 12 to separate the drive member 31 from the working area of ​​the clamping assembly 20, so as to avoid the drive member 31 from affecting the clamping and processing of the workpiece, and further optimize the structural layout of the clamping device 100.

[0037] Please see Figure 1 In some embodiments, the linkage 32 includes a linkage body 321 and a connecting body 322. One end of the linkage body 321 is connected to the first gripper 21, and the other end of the linkage body 321 abuts against the pusher 33. The connecting body 322 protrudes from the side wall of the linkage body 321 and is connected to the drive member 31. The connecting body 322 is configured to drive the linkage body 321 to push the pusher 33 under the drive of the drive member 31.

[0038] Thus, through the above arrangement, the connecting body 322 and the linkage body 321 can be reasonably arranged, avoiding the linkage body 32 from interfering with the workpiece clamping and processing operations, while ensuring that the connecting body 322 stably drives the linkage body 321 to push the pusher 33 under the drive of the drive member 31, thereby improving the stability of the operation.

[0039] Please see Figure 1 In some embodiments, the linkage 321 is provided with a pushing part 3211 at one end near the pushing member 33. The pushing part 3211 is inclined relative to the movement direction of the second gripper 22. The pushing part 3211 abuts against the pushing member 33 and is configured to push the pushing member 33.

[0040] Thus, through the above configuration, the linkage 321 can push the pusher 33 through the inclined pusher 3211, so as to stably and quickly push the pusher 33 to push the second gripper 22, thereby improving the clamping efficiency.

[0041] Please see Figure 1In some embodiments, the pushing member 33 includes a movable body 331, a rolling body 332, and a pushing member 333. The movable body 331 is slidably connected to the base 10 in a direction perpendicular to the movement direction of the second gripper 22. The rolling body 332 is located at one end of the movable body 331 adjacent to the linkage member 32 and is rotatably connected to the movable body 331. The rolling body 332 abuts against the linkage member 32 and is configured to drive the movable body 331 to move under the push of the linkage member 32. The pushing member 333 is located on the side of the movable body 331 facing the second gripper 22 and is connected to the movable body 331. The pushing member 333 abuts against the second gripper 22 and is used to push against the second gripper 22.

[0042] Thus, through the above arrangement, the pushing member 33 can form a rolling contact with the linkage member 32 through the rolling body 332, thereby reducing the friction between the pushing member 33 and the linkage member 32. This facilitates the linkage member 32 to stably push the moving body 331 and the pushing member 333 through the rolling body 332, thereby enabling the pushing member 333 to smoothly and stably push the second gripper 22, thereby improving the gripping smoothness.

[0043] Please see Figure 1 In some embodiments, the pusher 333 is provided with a pusher ramp 3331 on the side facing the second gripper 22, and the pusher ramp 3331 is inclined relative to the movement direction of the second gripper 22.

[0044] Thus, through the above configuration, the pushing body 333 pushes the second gripper 22 through the pushing inclined surface 3331, thereby achieving the pushing of the second gripper to move closer to the first gripper 21.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
