Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, and in particular to an adjustable clutch pressure plate gripper. Background Technology

[0002] The existing technology, application number CN202111630422.3, describes a precision eccentric adjustment device for centerless grinding of bearing rings. It also includes a clutch pressure plate gripper. The clutch pressure plate has a thin wall thickness of only 10-15mm, making it prone to deformation during processing. Due to the poor rigidity of the thin-walled structure, it is susceptible to vibration under the influence of cutting forces, further increasing the risk of deformation. Furthermore, the existing technology uses a single clamping method, making stable clamping difficult. The workpiece is prone to loosening or shifting during processing, affecting machining accuracy and safety. Additionally, the irregular shape of each batch of products necessitates frequent fixture adjustments, increasing preparation time and reducing production efficiency.

[0003] Therefore, it is necessary to design an adjustable clutch pressure plate gripper to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable clutch pressure plate gripper to overcome the aforementioned shortcomings of the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable clutch pressure plate gripper includes a bottom fixed base, a plurality of slide rails disposed on the bottom fixed base, gripper blocks slidably mounted on the slide rails, a positioning disk disposed between the slide rails, and a positioning ring disposed on the positioning disk. An eccentric adjusting gear assembly with adjustable end clamping is disposed on both sides of the gripper blocks. The eccentric adjusting gear assembly includes adjusting teeth with their bottoms located within the upper part of the gripper blocks, a bolt passing through the gripper blocks and partially connected to the adjusting teeth, and an adjusting shim located within the bottom of the gripper blocks and within the bolt. The outer diameter of the upper part of the adjusting teeth is larger than the outer diameter of the lower part of the adjusting teeth, and the upper axis of the adjusting teeth and the lower axis of the adjusting teeth are located at different axes.

[0007] Preferably, the slide rails are evenly distributed around the center of the bottom fixing seat, and a slider is slidably installed inside the slide rail. The gripper block is fixed to the slider by bolts, and the slider has mounting holes for mounting the gripper block.

[0008] Preferably, a protrusion is provided at the rear end of the slide rail.

[0009] Preferably, the gripper block has a fixing hole, and the gripping end of the gripper block has an arc-shaped structure. The eccentric adjustment gear assembly is respectively disposed at both ends of the arc-shaped structure. The bottom of the gripper block has a groove, and the slide rail is embedded in the groove of the gripper block.

[0010] Preferably, the positioning disk has several sets of positioning blocks, and each set of positioning blocks is placed between the gripper blocks. The positioning ring is fixedly installed on the positioning blocks by a fixing member, and both the positioning ring and the positioning disk are installed at the center of the bottom fixing seat.

[0011] Preferably, the top of the positioning disk is configured in a gear-like structure.

[0012] The beneficial effects of this utility model are as follows: This technical solution uses multiple sets of clamping jaws evenly arranged around the bottom fixed base to prevent material from flying out. By adjusting the teeth to fully contact the workpiece, the stability of clamping can be greatly improved, effectively preventing material from flying out during processing, reducing safety risks, and ensuring the smooth progress of the processing. The uniform clamping force and stable clamping state help reduce vibration during processing, improve the cutting stability of the tool, extend tool life, and further improve processing quality. The use of rotatable adjustable teeth makes operation convenient and quick, reduces the technical requirements of operators, and improves work efficiency. At the same time, the adjustable design can quickly adapt to the shape changes of different batches of products without the need for a complicated adjustment process, greatly saving adjustment time and improving production efficiency. Precise clamping and stable processing state reduce the scrap rate, reduce the time and resources wasted due to scrap, and further improve production efficiency. Attached Figure Description

[0017] Reference Figures 1 to 3An adjustable clutch pressure plate gripper includes a bottom fixed base 1, a plurality of slide rails 2 disposed on the bottom fixed base, gripper blocks 3 slidably mounted on the slide rails, a positioning disk 4 disposed between the slide rails, and a positioning ring 5 disposed on the positioning disk. An eccentric adjustment gear assembly 6 with adjustable end clamping is provided on both sides of the gripper blocks.

[0018] The slide rails 2 are evenly distributed around the center of the bottom fixed base. A slider 21 is slidably installed inside the slide rail. The gripper block is fixed to the slider by bolts. The slider has mounting holes for mounting the gripper block. To prevent the gripper block from moving and misaligning, a protrusion 22 is provided at the rear end of the slide rail. The protrusion restricts the gripper block and prevents excessive adjustment.

[0019] The gripper block has a fixing hole and the gripping end of the gripper block has an arc-shaped structure. The eccentric adjustment tooth assembly is respectively set at both ends of the arc-shaped structure. The bottom of the gripper block has a groove and the slide rail is embedded in the groove of the gripper block to facilitate sliding adjustment of the position to adapt to products of different sizes for clamping.

[0020] The positioning disk 4 is provided with several sets of positioning blocks 41, and each set of positioning blocks is placed between the gripper blocks. The positioning ring is fixedly installed on the positioning block by a fastener. The positioning ring and the positioning disk are both installed at the center of the bottom fixed seat. They are all installed with the bottom fixed seat as the center, which facilitates positioning and enables quick installation.

[0021] The top of the positioning disk has a gear-shaped structure. During processing, this structure prevents processing waste from getting stuck in the positioning disk and allows it to be removed through the gear-shaped structure for easy cleaning.

[0022] The gripper blocks are respectively placed on the outside of the positioning disk;

[0023] The eccentric adjusting gear assembly 6 includes an adjusting gear 61 with its bottom located inside the upper part of the gripper block, a bolt 62 that passes through the gripper block and is partially connected to the adjusting gear, and an adjusting shim 63 located inside the bottom of the gripper block and inside the bolt. The outer diameter of the upper part of the adjusting gear is larger than the outer diameter of the lower part of the adjusting gear, and the axis of the upper part of the adjusting gear and the axis of the lower part of the adjusting gear are located at different axes. Therefore, the upper and lower parts of the adjusting gear are eccentric structures. Specifically, by rotating the adjusting gear, the angle of the gripper block can be finely adjusted. With the eccentric adjusting gear assembly 6, if it is for a thin-walled structure: because the adjusting gear can finely adjust the clamping amount, it can apply force more evenly to the thin-walled clutch pressure plate with a thickness of only 15mm, effectively reducing deformation during processing, ensuring dimensional accuracy and surface quality, and improving the overall processing accuracy of the product.

[0024] It also adapts to irregular shapes: Through the eccentrically designed adjustment teeth, it can be precisely adjusted according to each batch of products with irregular shapes, so that the clamping force distribution is more reasonable, avoiding processing errors caused by uneven clamping, thereby significantly improving the consistency and precision of the products.

[0025] In this implementation, the clamping size of the gripper block 3 is adjusted according to the size of the clutch pressure plate. The gripper block 3 is installed with a nut and a slider. Therefore, by adjusting the position of the slider 21 on the slide rail, the distance between the gripper block and the center is moved, thereby adjusting the size. The product is placed on the positioning ring, and the gripper blocks 3 around it wrap around and clamp the clutch pressure plate product. Since some clutch pressure plates may deform after processing, the gripper blocks may not be able to ensure that the product is clamped tightly, resulting in deviation. Therefore, at least three sets of gripper blocks are set, and each set has adjustment components on both sides. By rotating the adjustment teeth on both sides, the eccentricity is controlled, thereby achieving fine adjustment of the side end of the gripper block, thus ensuring that the end can fully contact the product.

[0026] The advantages of this utility model are as follows: This technical solution uses multiple sets of clamping jaws evenly arranged around the bottom fixed base to prevent material from flying out. By adjusting the teeth to fully contact the workpiece, the clamping stability can be greatly improved, effectively preventing material from flying out during processing, reducing safety risks, and ensuring the smooth progress of the processing. The uniform clamping force and stable clamping state help reduce vibration during processing, improve the cutting stability of the tool, extend tool life, and further improve processing quality. The use of rotatable adjustable teeth makes operation convenient and quick, reduces the technical requirements of operators, and improves work efficiency. At the same time, the adjustable design can quickly adapt to the shape changes of different batches of products without the need for a complicated adjustment process, greatly saving adjustment time and improving production efficiency. Precise clamping and stable processing state reduce the scrap rate, reduce the time and resources wasted due to scrap, and further improve production efficiency.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
