[0001] The utility model relates to the field of grinding devices, in particular to a forging piece grinding device which is convenient for adjusting the grinding angle. Background Art

[0002] Forgings refer to workpieces or blanks obtained by forging and deforming metal billets. Forgings have the following advantages: First, forging processing can improve the grain structure of the metal and improve its mechanical properties such as strength, toughness and wear resistance. Second, forging processing can eliminate defects inside metal materials and reduce pores and inclusions in parts, thereby improving the precision and surface quality of parts. Third, forging processing is characterized by high efficiency and can complete large-scale parts production in a shorter time. Therefore, forgings are widely produced on the market.

When a different grinding angle is required, the workpiece needs to be moved to achieve it. However, forgings are heavy and bulky, so this is very inconvenient and time-consuming and labor-intensive. Based on this, a forging grinding device that is easy to adjust the grinding angle is provided. Utility Model Content

The rotating rack 209 is meshed with the transmission gear 208. A first spring 2010 is fixedly connected to the outer wall of the rotating rack 209. One end of the first spring 2010 is fixedly connected to the inner wall of the workbench 201.

[0027] A limit assembly 4 is provided at the other end of the transmission gear 208 on the top of the workbench 201. The limit assembly 4 includes:

[0028] A third spring 401 is fixedly connected to the inner wall of the workbench 201, one end of the third spring 401 is fixedly connected to a limit rack 402, the limit rack 402 is distributed on one side of the workbench 201 close to the base 101 and is slidably connected to the workbench 201, and the limit rack 402 is meshed with the other end of the transmission gear 208;

[0029] An L-shaped baffle plate 403 is slidably connected to the outer wall of the limiting rack 402 away from the transmission gear 208, and a fixing plate 404 extending to the inside of the convex slide groove 202 is fixedly connected to the bottom wall of the L-shaped baffle plate 403. A fourth spring 405 is fixedly connected to one end of the outer wall of the fixing plate 404, and one end of the fourth spring 405 is fixedly connected to the inner wall of the workbench 201;

[0030] The upper wall of the transmission gear 208 is provided with a clamping assembly 3, and the clamping assembly 3 includes:

[0031] A connecting plate 301 fixedly connected to the upper wall of the transmission gear 208, wherein a horizontal slide groove 302 extending to the top of the connecting plate 301 is provided inside the connecting plate 301, a second spring 303 is fixedly connected to the inner wall of the horizontal slide groove 302, and one end of the second spring 303 is fixedly connected to a limiting block 304;

[0032] The outer wall of the bottom plate 203 is fixedly connected with an electric push rod 2011 for driving the bottom plate 203 to slide, the outer wall of the electric push rod 2011 is fixedly connected with a connecting block 2012, and the bottom wall of the connecting block 2012 is fixedly connected with the upper wall of the workbench 201;

[0033] The top of the workbench 201 is provided with a T-slot for the rotating rack 209 and the limiting rack 402 to slide in a limited manner, and the bottoms of the rotating rack 209 and the limiting rack 402 are formed with a T-slot sliding block that matches the T-slot.

[0034] In this embodiment: when it is necessary to grind the forged piece, first pull the limit block 304 along the outside of the horizontal slide 302, and then put the forged piece between the two limit blocks 304. At this time, release the hand pulling the limit block 304. The second spring 303 drives the two limit blocks 304 to move towards each other to clamp and fix the forged piece. At this time, start the electric push rod 2011, and the electric push rod 2011 pushes the transmission component 2 and the clamping component 3 to move along the outer wall of the grinding disc 103 as a whole. In this process, the ratchet 206 restricts the rotation of the ratchet wheel 205 and the transmission gear 208, so the transmission gear 208 rotates in the process of moving forward. The movable rack 209 is squeezed so that the rotating rack 209 moves along the end of the workbench 201 until the bottom plate 203 contacts and squeezes the fixed plate 404, so that the fixed plate 404 moves toward the base 101 and squeezes the fourth spring 405 to contract. In this process, the fixed plate 404 gradually squeezes the limiting rack 402, so that the limiting rack 402 approaches along the transmission gear 208, until the limiting rack 402 is engaged with the transmission gear 208, so as to limit the clamping assembly 3 and prevent the grinding sheet 103 from causing the clamping assembly 3 and the casting to shake when the casting is ground.

[0035] After the grinding disc 103 finishes grinding the casting, the electric push rod 2011 drives the transmission assembly 2 and the clamping assembly 3 to move as a whole along the side away from the base 101. At this time, the bottom plate 203 gradually moves away from the fixed plate 404, releasing the squeeze on the fixed plate 404. At this time, the fourth spring 405 drives the fixed plate 404 to move and reset along the side away from the base 101. At this time, the moving fixed plate 404 drives the L-shaped baffle 403 to move synchronously along the side away from the grinding disc 103. At this time, the fixed plate 404 is not squeezed. The third spring 401 drives the limiting rack 402 to move and reset along the end of the workbench 201 until the limiting rack 402 is separated from the transmission gear 208. At this time, the rotation lock of the transmission gear 208 is released.

[0036] After that, the transmission gear 208 continues to move and meshes with the rotating rack 209. Since the locking direction of the ratchet 206 on the ratchet 205 is unidirectional, the ratchet 206 does not have the ability to lock the ratchet 205 at this time. Therefore, the ratchet 205 and the transmission gear 208 can rotate at this time, and the transmission gear 208 will rotate under the limiting effect of the rotating rack 209 when moving. At this time, the rotating transmission gear 208 drives the clamping assembly 3 and the casting to rotate to achieve the angle adjustment of the casting.

[0037] Afterwards, the electric push rod 2011 extends again to drive the clamping assembly 3 and the casting to move toward the grinding sheet 103 again, and the grinding sheet 103 grinds the casting at different angles. Through the cooperation of the above parts, the purpose of grinding the casting at different angles is achieved.

[0038] Please refer to Figures 1-2 The upper wall of the workbench 201 is provided with a slide rail 406 for the fixed plate 404 to slide, and the width of the slide rail 406 matches the sliding track of the fixed plate 404 .

[0039] In this embodiment: In order to achieve rotational locking of the clamping assembly 3, a slide rail 406 for the fixed plate 404 to slide is provided on the upper wall of the workbench 201, so that the fixed plate 404 can drive the L-shaped baffle 403 to move, thereby achieving the purpose of squeezing the limiting rack 402 and releasing the squeezing of the limiting rack 402, thereby achieving the purpose of rotational locking and rotation locking of the clamping assembly 3.

[0040] Please refer to Figures 1-2 The L-shaped baffle 403 is close to the limiting rack 402, and one end surface is an arc structure. The closer it is to the base 101, the thinner its thickness is. The rotating rack 209 and the limiting rack 402 are staggered along the moving direction of the transmission gear 208 and there is a gap between them.

[0041] In this embodiment: In order to achieve the extrusion of the limit rack 402 so that the limit rack 402 can move outward to achieve the rotation locking of the clamping component 3, the outer wall of the L-shaped baffle 403 is set to an arc surface structure to facilitate the L-shaped baffle 403 to squeeze the limit rack 402 outward, thereby achieving the rotation locking of the clamping component 3.

[0042] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
