Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically a multi-angle positioning fixture for cylinder production. Background Technology

[0002] A fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for inspection or processing. Also known as a clamp, a fixture, broadly speaking, can be any device used to quickly, conveniently, and safely install a workpiece at any stage of the manufacturing process.

[0003] According to the patent application CN 217965874U, "A positioning and machining fixture for a hydraulic breaker cylinder body is described as follows: 'A positioning and machining fixture for a hydraulic breaker cylinder body includes a base, a support seat fixedly mounted on the base, an electromagnetic chuck mounted above the support seat, clamping devices symmetrically arranged on the left and right sides of the electromagnetic chuck, a positioning device on the rear side of the electromagnetic chuck, and a drilling device on the front side of the electromagnetic chuck.' The purpose of this utility model is to provide a positioning and machining fixture for a hydraulic breaker cylinder body, solving the technical problems of cumbersome operation and displacement during machining. The base is equipped with an electromagnetic chuck and a positioning component; the electromagnetic chuck can firmly adhere the workpiece to the worktable base, and the positioning component assists in making the workpiece more stable during machining; this fixture also has a drilling device, which is simple to operate and has a high safety factor.'"

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In use, this utility model involves placing the cylinder on a base and using a cylinder to push the clamping plate, causing the slide cylinder to move in the slide groove and push the cylinder to the center position of the electromagnetic chuck. At the front of the base, a scale marking ensures the positioning block is precisely positioned in the positioning slide groove, pushing the cylinder to the designated position. However, in actual use, because the device requires manual placement of the cylinder on the electromagnetic chuck for clamping, it cannot effectively clamp cylinders of different sizes along the same centerline. Furthermore, the fixed clamping position prevents effective multi-angle clamping of the cylinder. Additionally, the cylinders processed by this device need to be manually removed from the chuck. Therefore, a multi-angle positioning fixture for cylinder production is needed to solve these problems. Utility Model Content

This embodiment provides a multi-angle positioning fixture for cylinder body production. Please refer to [link / reference]. Figure 1-5 This utility model provides a technical solution: a multi-angle positioning fixture for cylinder production, including a worktable 1, with mounting bolts 2 threaded inside the worktable 1, a support plate 3 fixedly connected to the bottom of the worktable 1, a buffer pad 4 fixedly connected to the bottom of the support plate 3, a clamping and processing mechanism 5 inside the worktable 1, and an auxiliary limiting mechanism 6 on the top of the worktable 1.

Example

[0035] Based on Embodiment 1, in the prior art, the processed cylinder body needs to be manually removed from inside the suction cup by a worker. Therefore, this utility model provides Embodiment 2 to solve the above-mentioned technical problem. Please refer to Embodiment 2. Figure 6-7 Furthermore, in conjunction with Embodiment 1, the auxiliary limiting mechanism 6 includes a connecting platform 61, which is fixedly connected to the top of the workbench 1. A first bevel gear 62 is rotatably connected inside the connecting platform 61, and a threaded rod 67 is rotatably connected inside the connecting platform 61. A second bevel gear 68 is fixedly connected to the outside of the threaded rod 67. A limiting rod 69 is fixedly connected inside the connecting platform 61, and a movable block 63 is slidably connected to the outside of the limiting rod 69. A bellows baffle 610 is fixedly connected to the outside of the movable block 63. A clamping cylinder 64 is fixedly connected to the end of the movable block 63 away from the connecting platform 61. A connecting plate 65 is fixedly connected to the end of the clamping cylinder 64 away from the movable block 63. A second clamping plate 66 is provided at the end of the connecting plate 65 away from the clamping cylinder 64. A locking bolt is provided between the connecting plate 65 and the second clamping plate 66 to facilitate the adjustment of the height of the clamping cylinder 64, thereby meeting the needs of using cylinders of different heights.

[0037] In actual operation, when this device is used, the operator first places the cylinder to be processed inside the clamping table 511. The operator adjusts the height according to the cylinder. The operator rotates the first bevel gear 62. The rotation of the first bevel gear 62, in conjunction with the second bevel gear 68, causes the threaded rod 67 to rotate inside the connecting table 61. In conjunction with the limiting rod 69, the movable block 63 slides inside the connecting table 61, thereby moving the clamping cylinder 64. The operator then rotates the worm gear 514. The rotation of the worm gear 514, in conjunction with the worm wheel 516, causes the gear column 515 to rotate inside the support frame 513, thereby causing the cover plate 512 to rotate outside the clamping table 511. In conjunction with the limiting post 518, the first clamping plate 512 rotates. 17 slides inside the clamping table 511 to satisfy the clamping and limiting of cylinders of different diameters. The clamping cylinder 64 works to move the connecting plate 65, which, in conjunction with the locking bolt, moves the second clamping plate 66 to fully clamp the cylinder. After clamping, the cylinder is processed by the external equipment. After processing, the clamping cylinder 64 works to reverse the worm gear 514, thereby removing the limiting of the processed cylinder. The electromagnet 522 works, which, in conjunction with the spring 525, moves the adsorption block 526, which, in conjunction with the slider 523, moves the top plate 524, thereby allowing the processed cylinder inside the clamping table 511 to be ejected for easy handling by the operator.
