Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic gripping mechanism technology, specifically to a hydraulic gripping mechanism for a machining tool used in automotive bushing processing. Background Technology
[0002] In the manufacturing of automotive parts, rubber bushings need to be pressed into multiple locations on the vehicle axle. These rubber bushings are mainly used to support the vehicle's suspension components, and through elastic deformation, they achieve functions such as vibration reduction, shock absorption, and buffering, thereby ensuring the vehicle's driving safety and handling stability.
[0003] Press-fitting of automotive axle bushings is a crucial step in automotive suspension assembly. Axle bushings are typically pressed using hydraulic presses or pneumatic presses. Before pressing, the bushings need to be inspected and identified, including their code, model, shape, and placement. Different axle specifications have specific processing regulations. Currently, this inspection and identification is usually done manually, which is prone to errors and inefficient. While hydraulic gripping mechanisms are used, the different gripping forces required for rubber and metal bushings necessitate changing the grippers when gripping bushings of different materials, thus impacting processing efficiency.
[0004] Therefore, it is necessary to invent a hydraulic gripping mechanism for a machining tool used for processing automotive bushings to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a hydraulic gripping mechanism for a machining tool used in automotive bushing processing. By cooperating with the mounting table and the self-adaptive hydraulic gripping mechanism, the gripper can adapt to different materials, thereby solving the problem in the prior art that the gripping force required for rubber bushings and metal bushings is different, and that the gripper needs to be changed when gripping bushings of different materials, thus affecting the processing efficiency.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic gripping mechanism for a machining tool used for automotive bushing processing, comprising a mounting table, three sets of self-adaptive hydraulic gripping mechanisms arranged on the outer side of the mounting table, each self-adaptive hydraulic gripping mechanism including three sets of first connecting rods hinged to the outer wall of the mounting table, the bottom end of each first connecting rod being hinged to a non-circular connecting rod, the bottom end of each non-circular connecting rod being fixedly connected to a first assembly shell, the bottom end of each first assembly shell being fixedly connected to a clamping shell, the inner side wall of each clamping shell being fixedly connected to a rubber clamping sleeve, the interior of each clamping shell having an installation groove, the top wall of each first assembly shell being fixedly connected to a built-in electromagnet, the output end of which is provided with a magnetic filling block, activating the built-in electromagnet causes the magnetic filling block to fill the clamping shell downwards, changing the hardness of the clamping shell to increase the clamping force, thereby adapting to bushings of different materials.
[0007] Preferably, the inner wall of the clamping housing is provided with a first sliding groove and a second sliding groove. The magnetic filling block is slidably connected inside the first sliding groove and the mounting groove. The path and orientation of the magnetic filling block are restricted by the cooperation of the first sliding groove and the second sliding groove.
[0008] Preferably, a magnetic pole converter is fixedly connected to the outside of the first assembly shell. The magnetic pole converter is electrically connected to the built-in electromagnet and changes the magnetic pole of the built-in electromagnet through the magnetic pole converter.
[0009] Preferably, the inner wall of the rubber clamping sleeve is fixedly connected with several sets of protrusions, and the surface of the rubber clamping sleeve is engraved with friction texture, thereby further improving the clamping force of the rubber clamping sleeve.
[0010] Preferably, a hydraulic cylinder is fixedly connected to the top of the mounting platform, and a lifting block is fixedly connected to the output end of the hydraulic cylinder. Activating the hydraulic cylinder drives the lifting block to move up and down.
[0011] Preferably, the outer wall of the lifting block is fixedly connected with three sets of connecting blocks. The connecting blocks are hinged to the end of the irregular connecting rod away from the first connecting rod. The lifting block and the connecting blocks work together to drive the self-adaptive hydraulic gripping mechanism to move inward or outward.
[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0013] By cooperating with the mounting platform and the self-adaptive hydraulic gripping mechanism, when it is necessary to clamp the metal bushing, the magnetic pole converter is activated to switch the magnetic poles of the built-in electromagnet. Under the constraint of the first and second sliding grooves, the magnetic filling block slides downward in a fixed posture, thereby filling the interior of the clamping shell. When the hydraulic cylinder drives the lifting block to retract upward, the connecting block drives the irregular connecting rod to rotate inward. This, in conjunction with the first connecting rod and other parts, causes the rubber clamping sleeve to move inward, thereby achieving the clamping of the bushing. Because the magnetic filling block fills the clamping shell, the clamping force of the rubber clamping sleeve is increased. When it is necessary to clamp the rubber bushing, the above operation is repeated in reverse to increase the deformation space of the rubber clamping sleeve, thereby avoiding damage to the rubber bushing due to over-clamping.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0022] This utility model provides, for example Figure 1-4The hydraulic gripping mechanism of a machining tool for automotive bushing processing, as shown, includes a mounting platform 1. Three sets of self-adaptive hydraulic gripping mechanisms 2 are arranged on the outer side of the mounting platform 1. Each self-adaptive hydraulic gripping mechanism 2 includes three sets of first connecting rods 201 hinged to the outer wall of the mounting platform 1. A shaped connecting rod 202 is hinged to the bottom end of each first connecting rod 201. A first assembly shell 203 is fixedly connected to the bottom end of the shaped connecting rod 202. A clamping shell 204 is fixedly connected to the bottom end of the first assembly shell 203. A rubber clamping sleeve 205 is fixedly connected to the inner wall of the clamping shell 204. An installation groove 211 is provided inside the clamping shell 204. A built-in electromagnet 207 is fixedly connected to the top wall of the first assembly shell 203. The output end of the built-in electromagnet 207 is equipped with a magnetic... The filling block 208, when activated by the built-in electromagnet 207, moves the magnetic filling block 208 downward to fill the clamping shell 204, changing the hardness of the clamping shell 204 to increase the clamping force, thereby adapting to bushings of different materials. The inner wall of the clamping shell 204 has a first sliding groove 209 and a second sliding groove 210. The magnetic filling block 208 is slidably connected to the interior of the first sliding groove 209 and the mounting groove 211. The cooperation of the first sliding groove 209 and the second sliding groove 210 restricts the path and orientation of the magnetic filling block 208. A magnetic pole converter 206 is fixedly connected to the outer side of the first assembly shell 203. The magnetic pole converter 206 is electrically connected to the built-in electromagnet 207, changing the... The inner wall of the rubber clamping sleeve 205 is fixedly connected to several sets of protrusions, and the surface of the rubber clamping sleeve 205 is engraved with friction textures to further improve the clamping force of the rubber clamping sleeve 205. A hydraulic cylinder 3 is fixedly connected to the top of the mounting platform 1, and a lifting block 4 is fixedly connected to the output end of the hydraulic cylinder 3. Activating the hydraulic cylinder 3 drives the lifting block 4 to move up and down. Three sets of connecting blocks 5 are fixedly connected to the outer wall of the lifting block 4. The connecting blocks 5 are hinged to the end of the irregular connecting rod 202 away from the first connecting rod 201. Through the cooperation of the lifting block 4 and the connecting blocks 5, the self-adaptive hydraulic gripping mechanism 2 moves inward or outward. Through the cooperation of the mounting platform 1 and the self-adaptive hydraulic gripping mechanism 2, when it is necessary to clamp the metal bushing, the magnetic poles are activated. The converter 206 reverses the magnetic poles of the built-in electromagnet 207, causing the magnetic filling block 208 to slide downwards in a fixed posture under the constraint of the first sliding groove 209 and the second sliding groove 210. This fills the interior of the clamping shell 204 with the magnetic filling block 208. When the hydraulic cylinder 3 drives the lifting block 4 to retract upwards, the connecting block 5 drives the irregular connecting rod 202 to rotate inwards. This, in conjunction with the first connecting rod 201 and other parts, causes the rubber clamping sleeve 205 to move inwards, thereby clamping the bushing. Because the magnetic filling block 208 fills the clamping shell 204, the clamping force of the rubber clamping sleeve 205 is increased. When clamping the rubber bushing, the above operation is repeated in reverse to increase the deformation space of the rubber clamping sleeve 205.This prevents damage to the rubber bushing caused by excessive clamping of the rubber clamping sleeve 205.
[0023] The working principle of this practical application is as follows:
[0024] Refer to the instruction manual appendix Figure 1-4 When it is necessary to clamp the metal bushing, the magnetic pole converter 206 is activated to switch the magnetic poles of the built-in electromagnet 207, causing the magnetic filling block 208 to slide downward in a fixed posture under the constraint of the first sliding groove 209 and the second sliding groove 210. This allows the magnetic filling block 208 to fill the interior of the clamping shell 204. When the hydraulic cylinder 3 drives the lifting block 4 to retract upward, the connecting block 5 drives the irregular connecting rod 202 to rotate inward. This, in conjunction with the first connecting rod 201 and other parts, causes the rubber clamping sleeve 205 to move inward, thereby clamping the bushing. Because the magnetic filling block 208 fills the clamping shell 204, the clamping force of the rubber clamping sleeve 205 is increased. When it is necessary to clamp the rubber bushing, the above operation is repeated in reverse to increase the deformation space of the rubber clamping sleeve 205, thereby avoiding damage to the rubber bushing caused by excessive clamping.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
