Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, and more specifically, to a gear processing gripping device. Background Technology

[0002] A gear is a mechanical component with teeth on its rim that can continuously mesh to transmit motion and power. In gear manufacturing, gears need to go through multiple processes. When a gear goes through different processes, it needs to be gripped by a gripping device. Then, the gripped gear is transferred by the gripping device to the corresponding process for further processing.

[0003] For example, the gear processing gripper disclosed in patent CN218964261U, while facilitating the simultaneous movement of multiple clamping plates through the cooperation of components such as a motor, a first gear, and a threaded rod to clamp the gears being processed, thus reducing the operational difficulty and increasing work efficiency, and with the clamping plates fixed to the mounting plate by bolts for easy disassembly and replacement, and for clamping gears of different specifications, has significant drawbacks in actual use. When the clamping plates need to be replaced, multiple bolts must be removed sequentially from the corresponding mounting plates before the clamping plates on the mounting plates can be replaced. After the replacement, the clamping plates are then fixed back onto the corresponding mounting plates using multiple bolts. This process of removing and installing the clamping plates on the mounting plates is cumbersome, making clamping plate replacement inconvenient, and therefore requires improvement.

[0033] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0034] The following is in conjunction with the appendix Figures 1-5 This embodiment will be described in further detail.

[0035] like Figure 1 As shown, a gear processing gripping device in this embodiment includes a mounting frame, on which a lifting plate 100 is provided. A horizontal plate 110 is provided at one end of the lifting plate 100, and a fixed plate 111 is provided at both ends of the horizontal plate 110. A rotatable mounting plate 120 is provided between the two fixed plates 111. Opposing moving blocks 200 are provided on the lower end surface of the mounting plate 120. A cavity 301 is provided inside the mounting plate 120, and a driving assembly is provided inside the cavity 301. The driving assembly is used to drive the two moving blocks 200 to move closer or further away from each other.

[0036] Each movable block 200 is provided with a clamping plate 210 and an installation component. The installation component is used to install and remove the clamping plate 210 on the movable block 200.

[0037] The mounting frame is equipped with a flipping mechanism, which includes a lifting component on the mounting frame and a rotating component on the corresponding fixed plate 111. The lifting component is used to drive the mounting plate 120 to lift and lower, and the rotating component is used to drive the mounting plate 120 to rotate.

[0038] In this embodiment, by mounting the mounting frame on the moving device (existing structure), when the gear to be processed needs to be transferred to another process for processing, the moving device drives the mounting frame to move to a suitable position. The mounting frame drives the two fixed plates 111 to move via the lifting plate 100, so that the mounting plate 120 can move directly above the gear to be processed. At this time, the lifting assembly drives the mounting plate 120 to descend, so that the two moving blocks 200 drive the corresponding clamping plates 210 to be located on both sides of the gear to be processed. At this time, the driving assembly in the cavity 301 drives the two moving blocks 200 to move closer to each other, so that the two clamping plates 210 move closer to each other. When the two clamping plates 210 clamp against both sides of the gear to be processed, they grip the gear. At this time, the mounting plate 120 is driven to move upward by the lifting component, and the gear to be processed is moved upward by the two clamping plates 210. Then, the mounting frame is moved to another process by the moving device. Then, the mounting plate 120 is driven to move downward to a suitable position by the lifting component, and the two moving blocks 200 are driven to move away from each other by the driving component, so that the two clamping plates 210 release their grip on the gear to be processed, and the gear to be processed can fall into another process for subsequent processing.

[0039] When the moving device transfers the gear to be processed to another process via the mounting plate 120, the gripped gear to be processed is located on the lower end surface of the mounting plate 120. At this time, the gear to be processed may fall between the two clamping plates 210 due to its own weight, which may cause damage to the gear to be processed. In order to avoid the above situation, after the lifting component drives the mounting plate 120 to move upward, the rotating component drives the mounting plate 120 to rotate, so that when the two clamping plates 210 clamp and fix the gear to be processed, the gear to be processed can also be attached to one of the two clamping plates 210. This can prevent the gear to be processed from falling between the two clamping plates 210 due to its own weight when it is transferred to another process.

[0040] When the moving device drives the mounting frame to move to another process, the mounting plate 120 needs to be rotated and reset by the rotating component. After the mounting plate 120 completes the reciprocating motion and the gear to be processed is located on the lower end surface of the mounting plate 120, the lifting component can drive the mounting plate 120 to move down to a suitable position. Then, the driving component drives the two moving blocks 200 to move away from each other so that the two clamping plates 210 release the gripping of the gear to be processed, so that the gear to be processed can fall into another process for subsequent processing.

[0041] In order to ensure that the two clamping plates 210 can stably grip the gears to be processed, when the two clamping plates 210 need to grip gears of different diameters, it is necessary to replace the clamping plates 210 with different sizes. The clamping plates 210 can be removed from the moving block 200 by using the mounting component, and then the replaced clamping plates 210 can be installed on the corresponding moving block 200 by using the mounting component. Compared with the existing equipment, this gear processing gripping equipment is more convenient to disassemble and assemble the clamping plates 210 on the moving block 200 in actual use, thus facilitating the replacement of clamping plates 210 with different sizes.

[0042] The two clamping plates 210 have arc-shaped grooves on their opposite sidewalls. The clamping plates 210 can better fit with the sidewalls of the gear to be processed through the arc-shaped grooves so that the two clamping plates 210 can grip the gear to be processed. Rubber pads (not shown in the figure) are fixedly installed on the sidewalls of the arc-shaped grooves to make the gripping effect of the two clamping plates 210 on the gear to be processed better.

[0043] In actual use, the mounting frame includes a base 150, on which an L-shaped base plate 151 is fixedly installed. The base 150 is used to fix the moving device. A horizontal plate 110 is fixedly installed on the lifting plate 100, and two fixing plates 111 are fixedly installed on both sides of the horizontal plate 110.

[0044] like Figure 1-4 As shown, in this embodiment, the lower end surface of the mounting plate 120 is provided with a sliding groove 302 that is opposite to and communicates with the cavity 301. Each of the moving blocks 200 is provided with a connecting plate 401 with one end passing through the sliding groove 302 and extending into the cavity 301. Each of the connecting plates 401 located in the cavity 301 is provided with a moving plate 310. Each of the two moving plates 310 is provided with a first toothed rack 311 that is staggered from each other.

[0045] The drive assembly includes a first gear 320 disposed in the cavity 301 and meshing with the two first racks 311. A first motor 140 is disposed on the upper end surface of the mounting plate 120. The output shaft of the first motor 140 extends into the cavity 301 and is fixedly connected to the first gear 320. The first motor 140 drives the first gear 320 to rotate, thereby driving the two first racks 311 to move closer or further away from each other, so as to realize that the two moving blocks 200 move closer or further away from each other.

[0046] In this embodiment, the arrangement of the slide groove 302, connecting plate 401, moving plate 310, first rack 311, first gear 320, and first motor 140 ensures that the slide groove 302 is positioned along the moving direction of the moving block 200, the lower end of the connecting plate 401 is fixedly connected to the moving block 200, the moving plate 310 is fixedly mounted on the upper surface of the connecting plate 401, the first rack 311 is fixedly mounted on the corresponding moving plate 310, the first motor 140 is fixedly mounted on the mounting plate 120, and the first gear 320 is fixedly mounted on the first motor 140. On the output shaft, when the first motor 140 drives the first gear 320 to rotate, the rotation of the first gear 320, through its cooperation with the two first racks 311, enables the rotation of the first gear 320 to drive the two first racks 311 to move closer or further apart. The movement of the two first racks 311, through the corresponding moving plate 310, enables the connecting plate 401 to move along the slide groove 302. That is, the two connecting plates 401 drive the two moving blocks 200 to move closer or further apart, so that the two moving blocks 200 drive the corresponding clamping plate 210 to grip the gear to be processed.

[0047] In actual use, the side wall of the movable plate 310 slides and fits against the side wall of the cavity 301, so that the movable plate 310 can slide stably in the cavity 301, that is, the movable block 200 can move stably.

[0048] like Figure 1-4 As shown, in this embodiment, each side wall of the clamping plate 210 is provided with an insert plate 211 that is opposite to and penetrates the corresponding moving block 200, and the lower end of each moving block 200 is bent to form a bent portion 201.

[0049] The mounting assembly includes a movable plate 220 located on the lower end face of the bending portion 201. The lower end face of the movable plate 220 is provided with a plurality of movable rods 410 that penetrate the bending portion 201. The penetrating ends of the plurality of movable rods 410 are connected by a limiting plate 230. The limiting plate 230 is provided with opposing insert rods 420. Each movable rod 410 located between the limiting plate 230 and the bending portion 201 is fitted with a spring 411. The spring 411 is used to push the insert rod 420 into the corresponding insert plate 211, thereby realizing the installation of the clamping plate 210 on the moving block 200.

[0050] In this embodiment, the arrangement of the insert plate 211, the bending portion 201, the movable plate 220, the movable rod 410, the limiting plate 230, the insert rod 420, and the spring 411 ensures that the insert plate 211 is fixedly installed on the clamping plate 210, the two ends of the movable rod 410 are respectively fixedly connected to the movable plate 220 and the limiting plate 230, and the insert rod 420 is fixedly installed on the limiting plate 230. When the movable plate 220 is pulled away from the bending portion 201, the movable plate 211... 20. The limiting plate 230 is moved by the movable rod 410. At the same time, the limiting plate 230 compresses the spring 411. At this time, the insert plate 211 on the clamping plate 210 passes through the corresponding moving block 200. Then, the pull on the movable plate 220 is released, so that the spring 411 is released from compression, pushing the limiting plate 230 to move towards the insert plate 211, and inserting the rod 420 into the insert plate 211, so as to realize the installation of the clamping plate 210 on the moving block 200.

[0051] When it is necessary to remove the clamping plate 210 from the moving block 200, by pulling down the movable plate 220, the movable plate 220 drives the limiting plate 230 away from the insert plate 211 through the movable rod 410, and the insert rod 420 slides out from the insert plate 211. Then, by sliding the clamping plate 210, the insert plate 211 on the clamping plate 210 slides out from the moving block 200, thereby removing the clamping plate 210 from the moving block 200.

[0052] Damping pads are fitted on both ends of the movable rod 410 and located at both ends of the spring 411. The damping pads can reduce the shaking of the spring 411.

[0053] In actual use, the movable plate 220 is provided with a pull hole for pulling the movable plate 220, which makes it easy to pull the movable plate 220 away from the bending part 201.

[0054] like Figure 1 As shown, in this embodiment, a lifting block 101 is provided on the opposite side wall of the lifting plate 100, and a limiting rod 102 is provided on the mounting frame that is opposite to and passes through the corresponding lifting block 101.

[0055] The lifting assembly includes a rotatable threaded rod 103 mounted on a mounting frame. The threaded rod 103 is threaded through the lifting plate 100. The rotation of the threaded rod 103 drives the lifting plate 100 to lift and lower, thereby realizing the lifting and lowering of the mounting plate 120.

[0056] In this embodiment, by setting up the lifting block 101, the limiting rod 102 and the threaded rod 103, the lifting block 101 is fixedly installed on the lifting plate 100, and the upper and lower ends of the limiting rod 102 are respectively fixedly installed on the base plate 151 and the base 150. The limiting rod 102 passes through the corresponding lifting block 101 to limit the lifting plate 100. The upper and lower ends of the threaded rod 103 are rotatably installed on the base plate 151 and the base 150 through bearings. When the threaded rod 103 rotates, it can drive the lifting plate 100 to rise and fall. The rise and fall of the lifting plate 100 can drive the two fixed plates 111 to rise and fall through the horizontal plate 110, that is, the mounting plate 120 to rise and fall.

[0057] In actual use, a second motor 104 is fixedly installed on the base plate 151. The output shaft of the second motor 104 is fixedly connected to the threaded rod 103, so that the threaded rod 103 can be driven to rotate by the second motor 104.

[0058] like Figure 1-5 As shown, in this embodiment, the upper surface of the mounting plate 120 is provided with opposing supports 121, and each support 121 is provided with a mounting shaft 122 that penetrates the corresponding fixing plate 111. The penetrating end of the mounting shaft 122 is fitted with a second gear 123.

[0059] The rotating assembly includes an electric push rod 130 disposed on one side wall of the fixed plate 111. The output end of the electric push rod 130 is provided with a second rack 131 that meshes with the second gear 123. The electric push rod 130 drives the second rack 131 to move, thereby enabling the second gear 123 to drive the mounting plate 120 to rotate.

[0060] In this embodiment, the arrangement of the support 121, mounting shaft 122, second gear 123, electric push rod 130, and second rack 131 allows the support 121 to be fixedly mounted on the mounting plate 120, the mounting shaft 122 to be fixedly mounted on the support 121, the mounting shaft 122 to be connected to the fixed plate 111 via a bearing, the second gear 123 to be fixedly mounted on the mounting shaft 122, and the second rack 131 to be fixedly mounted on the second gear 123. When the electric push rod 130 drives the second rack 131 to move, the second rack 131 can drive the mounting shaft 122 to rotate via the second gear 123. The mounting shaft 122 then drives the mounting plate 120 to rotate via the support 121, thereby allowing the gear to be processed on the lower end face of the mounting plate 120 to be engaged on one of the two clamping plates 210.

[0061] Among them, L-shaped positioning plates 500 are fixedly installed on the other side wall of the fixing plate 111. A positioning rod 501 with one end inserted into the corresponding second rack 131 is fixedly installed on the positioning plate 500. The positioning rod 501 limits the second rack 131, so that the second rack 131 can move more stably, thereby better driving the second gear 123 to rotate.

[0062] A positioning frame 132 is fixedly installed on one side wall of the fixing plate 111, and an electric push rod 130 is fixedly installed on the positioning frame 132 to realize the installation of the electric push rod 130 on the fixing plate 111.

[0063] In actual use, the rotation angle of the mounting plate 120 is greater than 90 degrees and less than 180 degrees.

[0064] In practical use, the mounting bracket is moved to a suitable position by a moving device, positioning the mounting plate 120 directly above the gear to be processed. At this point, the second motor 104 drives the threaded rod 103 to rotate, causing the lifting plate 100 to move downwards, which in turn drives the mounting plate 120 downwards. Once the mounting plate 120 has moved to the suitable position, the first motor 140 drives the first gear 320 to rotate, causing the two moving plates 310 to move closer together. The two moving plates 310 are then moved by the connecting plate 401 driving the moving block 200 to move, allowing the two clamping plates 210 to grip the gear to be processed. Then, the second motor 104 drives the threaded rod 103 to rotate, raising the lifting plate 100 and the mounting plate 120 to a suitable height. The second rack 131 is moved by the electric push rod 130, causing the mounting plate 120 to rotate. After the mounting plate 120 has rotated to a certain angle, the moving device moves the mounting frame to another process. After the gear to be processed has moved to another process, the second rack 131 is moved by the electric push rod 130 to reset the rotation of the mounting plate 120. Then, the threaded rod 103 is rotated by the second motor 104, driving the mounting plate 120 to move downward. After the mounting plate 120 moves downward, the first gear 320 is rotated by the first motor 140, causing the two moving blocks 200 to move away from each other and releasing the gripping of the gear to be processed by the two clamping plates 210. At this time, the gear to be processed falls into another process for subsequent processing.

[0065] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
