Mechanical parts are not only a discipline for researching and designing mechanical basic parts in various equipment, but also a general term for parts and components.

[0003] For the current grinding device, there is a prior art edge grinding device for mechanical part production disclosed in the patent number "CN215147568U". By starting the second motor and winding up the traction rope, the traction rope pulls the second runner upward through the first runner, so as to drive the grinding device to move upward. Then loosen the traction rope of the second motor to make the second runner move downward, and the grinding device moves downward accordingly, thus achieving the effect of adjusting the height of the grinding device as needed. This device lifts and lowers its grinding device through the traction rope. After long-term use, the traction rope continuously rubs against the two transmission wheels, which will cause the traction rope to wear and break, and there is a risk of falling. Accordingly, the present application proposes a mechanical part edge grinding device in the utility model content. Utility Model Content

The output end of the cylinder 2 is fixedly connected to a slide plate 3. A support block 4 is fixed on the top of the slide plate 3. A rotating rod 5 is rotatably connected in the middle of the support block 4. A placing plate 6 is fixedly sleeved outside the rotating rod 5.

A support 9 is fixed on the top of the grinding table 1. A telescopic rod 10 is fixed on the top of the support 9. A lifting frame 11 that can slide up and down is installed at the bottom of the telescopic rod 10. An electric grinding head 12 is installed at the bottom of the lifting frame 11. It should be noted that the electric grinding head 12 is composed of a driving machine, an output shaft and a grinding head. The driving machine drives the conveying shaft to drive the grinding head to rotate and slide along the surface of the mechanical part to perform grinding treatment on it. This technical solution uses the existing technology in the field. The specific model specifications need to be selected according to the actual specifications of the device, etc. The specific selection calculation method uses the existing technology in the field, so it will not be elaborated.

[0021] The bottom of the slide plate 3 is convexly arranged. A chute 101 is opened on the surface of the grinding table 1. The convex part at the bottom of the slide plate 3 slides horizontally in the chute 101. It should be noted that convex blocks are symmetrically arranged at the bottom of the slide plate 3, and the convex blocks are embedded in the chute 101 and slide horizontally. When the cylinder 2 is driving, it is guided and limited, so that the placing plate 6 slides stably horizontally.

[0022] A fixing block 61 is fixed to the top of the placing plate 6. There are two fixing blocks 61. A threaded rod 62 is rotatably connected between the two fixing blocks 61. A rocker 63 is fixed to the end side of the threaded rod 62. A slider 64 is threadedly sleeved on the outer part of the threaded rod 62. A connecting rod 65 is hinged to the end side of the slider 64. The connecting rod 65 is hinged to the placing plate 6. A double-headed screw rod 81 is rotatably connected inside the groove 7. A rotating rod 82 is fixed to the end side of the double-headed screw rod 81. A sliding block 83 is threadedly sleeved on the outer part of the double-headed screw rod 81. The sliding block 83 is fixedly connected to the clamping plate 8. It should be noted that two sliding blocks 83 are sleeved on the outer part of the double-headed screw rod 81, and the two sliding blocks 83 slide horizontally synchronously to achieve the clamping effect.

[0023] A motor 1101 is fixed to the top of the bracket 9. A coupling 1102 is fixedly connected to the output end of the motor 1101. A worm 1103 is fixed to the bottom of the coupling 1102. An installation seat 1106 is fixed to the top inner wall of the bracket 9. A support shaft 1105 is fixed in the middle of the installation seat 1106. A worm gear 1104 is rotatably sleeved on the outer part of the support shaft 1105. The worm gear 1104 meshes with the worm 1103. A crank 1107 is fixedly sleeved on the end side of the worm gear 1104. An annular groove 1108 is formed inside the crank 1107. A convex rod 1109 is slidably connected inside the annular groove 1108. The convex rod 1109 is fixedly connected to the lifting frame 11.

[0024] In the present utility model, when grinding mechanical parts, first place them on the placing plate 6, manually rotate the rotating rod 82 to drive the double-headed screw rod 81 to rotate. When the double-headed screw rod 81 rotates, the two sliding blocks 83 symmetrically installed on its outer part will drive the clamping plate 8 to slide in the same direction, so as to clamp and fix the mechanical parts, so that they will not shake and shift during the grinding process, and avoid deviation and defects in grinding;

[0025] Then start the cylinder 2 to drive the sliding plate 3 to slide horizontally along the sliding groove 101 to the bottom of the electric grinding head 12. Start the motor 1101 to drive the coupling 1102 to drive the worm 1103 to rotate. When the worm 1103 rotates, it meshes with the worm gear 1104. The worm gear 1104 rotates around the support shaft under the force. The crank 1107 on its end side also rotates around the support shaft accordingly. As the crank 1107 rotates, the convex rod 1109 is forced to slide in the annular groove 1108 of the crank 1107, thereby driving the lifting frame 11 installed through the convex rod 1109 to lift and stretch the telescopic rod 10, so that the lifting frame 11 drives the electric grinding head 12 to lift and fit the surface of the mechanical parts for grinding treatment;

[0026] When it is necessary to adjust the grinding angle of mechanical parts during the grinding process, manually rotate the rocker 63 to drive the threaded rod 62 to rotate within the fixed block 61. When the screw rotates, the slider 64 sleeved on its external thread slides horizontally immediately, and at the same time drives the connecting rod 65 to rotate, causing the placement plate 6 to tilt, thereby finely adjusting the grinding angle, so that during the grinding process, it can be adjusted according to the grinding position required by the corners of the mechanical parts, improving the flexibility of its use.

[0027] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent replacements or changes, should be covered within the protection scope of the present invention.
