Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to an automotive parts grinding fixture. Background Technology

[0002] Ring-shaped automotive parts are a type of automotive component. After initial production, the surface of ring-shaped automotive parts has extremely fine microscopic metal particles, which are called burrs. These burrs need to be removed from the surface of the ring-shaped automotive parts. Existing grinding machines are only suitable for ring-shaped automotive parts of specific specifications, and have poor versatility. When grinding ring-shaped automotive parts of various specifications, multiple grinding machines are required, which is costly.

[0003] Existing patent CN211072943U describes an automotive parts grinding machine comprising a base and a turntable and a grinding wheel horizontally mounted on the base. The turntable is rotatably connected to the base. A groove is provided at the center of the turntable, and an annular automotive part is placed on the turntable, positioned above the groove. A fixed positioning block and a movable positioning block are positioned opposite each other within the groove, their upper ends extending vertically upwards from the groove to the inner side of the automotive part. The fixed positioning block is fixedly installed within the groove and abuts against the inner side of the automotive part. The movable positioning block is slidably installed within the groove, moving closer to or away from the fixed positioning block until it separates from or abuts against the inner side of the automotive part, thus loosening or fixing the automotive part. The grinding wheel is horizontally slidably mounted on the base and positioned to move closer to or away from the turntable, its lower surface conforming to the automotive part. The advantages are that it is suitable for grinding annular automotive parts of different specifications, has strong versatility, and saves costs.

[0004] In actual use, the location of burrs on parts is uncertain and may appear on the side of the part. However, the angle of the grinding wheel in existing equipment is fixed, which means that existing equipment cannot grind off the burrs on the side of the part, resulting in low practicality. Utility Model Content

[0005] The purpose of this utility model is to provide a grinding fixture for automotive parts, which solves the problem that the angle of the grinding wheel in existing equipment is fixed, which makes the existing equipment unable to grind off the burrs on the side of the parts and has low practicality.

[0006] To achieve the above objectives, this utility model provides a grinding fixture for automotive parts, including a worktable, a clamp, and a grinding assembly. The clamp is mounted above the worktable. The grinding assembly includes a mounting base, a moving component, a mounting frame, a rotating shaft, a rotating component, a rotating block, and a grinding wheel.

The rotating component is mounted on the rotating shaft and drives the rotating shaft to rotate. The rotating block is fixedly connected to the rotating shaft and located on the side of the rotating shaft closest to the mounting frame. The grinding wheel is fixedly connected to the rotating block and located on the side of the rotating block furthest from the rotating shaft.

[0007] The movable component includes a mounting cylinder and a drive rod. The mounting cylinder is fixedly connected to the mounting base and is located on the side of the mounting base away from the worktable. The drive rod is slidably connected to the mounting cylinder and is located on the side of the mounting cylinder away from the mounting base, and is connected to the mounting frame.

[0008] The rotating component includes a rotating ring, a mounting shell, and a limiting element. The rotating ring is fixedly connected to the rotating shaft and is located on the side of the rotating shaft away from the mounting frame. The mounting shell is fixedly connected to the mounting frame and is located on the side of the mounting frame closer to the rotating ring. The limiting element is mounted on the mounting shell and restricts the rotation of the rotating shaft.

[0009] The limiting element includes a limiting block, a telescopic rod, a locking block, and a driving component. The limiting block is fixedly connected to the rotating shaft and located at one end of the rotating shaft near the mounting housing. The telescopic rod is fixedly connected to the mounting housing and located on the side of the mounting housing away from the limiting block. The locking block is fixedly connected to the telescopic rod and located on the side of the telescopic rod away from the mounting housing, and engages with the limiting block.

[0020] This utility model provides a grinding fixture for automotive parts, including a worktable 100, a clamp 101, and a grinding assembly. The grinding assembly includes a mounting base 102, a moving component, a mounting frame 103, a rotating shaft 104, a rotating component, a rotating block 105, and a grinding wheel 106. The moving component includes a mounting cylinder 107 and a drive rod 108. The rotating component includes a rotating ring 109, a mounting shell 110, and a limiting element. The limiting element includes a limiting block 111, a telescopic rod 112, a locking block 113, and a driving component. The driving component includes a spring 114 and a moving block 115. This solution solves the problem that the angle of the grinding wheel 106 in existing equipment is fixed, which prevents the existing equipment from grinding away burrs on the side of the parts, resulting in low practicality.

[0021] In this specific embodiment, the clamp 101 is installed above the worktable 100. The clamp 101 is a fixing structure described in the existing patent technology CN211072943U, "An Automotive Parts Grinding Machine". The clamp 101 is installed above the worktable 100 to fix the parts to be ground, thereby facilitating the grinding of burrs on the parts. This solution enables the angle of the grinding wheel 106 to be adjusted according to the position of the burrs, thereby facilitating the grinding of burrs at different angles and improving the practicality of the equipment.

[0022] The mounting base 102 is fixedly connected to the worktable 100 and located on the side of the worktable 100 closer to the clamp 101. The mounting frame 103 is connected to the mounting base 102 via the moving component, which drives the mounting frame 103 to move. The rotating shaft 104 is rotatably connected to the mounting frame 103 and located on the side of the mounting frame 103 away from the mounting base 102. The rotating component is mounted on the rotating shaft 104 and drives the rotating shaft 104 to rotate. The rotating block 105 is fixedly connected to the rotating shaft 104. The grinding wheel 106 is fixedly connected to the rotating block 105 and located on the side of the rotating block 105 away from the rotating shaft 104. The mounting base 102 is bolted to the worktable 100. The mounting frame 103 is mounted above the mounting base 102 via the moving component, which drives the mounting frame 103 to move up and down, thereby improving the automation level of the equipment. The rotating shaft 104 is mounted on the mounting frame 103 via bearings, allowing the rotating shaft 104 to move within the mounting frame. The rotating component is mounted on one end of the rotating shaft 104, driving the rotating shaft 104 to rotate and restricting its rotation to prevent rotation during use. The rotating block 105 is bolted to the rotating shaft 104, causing the rotating shaft 104 to rotate. The grinding wheel 106 is the grinding wheel described in the prior art patent CN211072943U, a grinding machine for automotive parts. The grinding wheel 106 is fixedly mounted on the rotating shaft 104. The rotating block 105 is located away from the rotating shaft 104. The grinding wheel 106 grinds burrs on the parts. The rotating component drives the rotating shaft 104 to rotate, which in turn drives the rotating block 105 to rotate, thereby changing the angle of the grinding wheel 106. The moving component drives the mounting bracket 103 to move, so that the grinding wheel 106 comes into contact with the parts and can grind the burrs on the parts. This allows the angle of the grinding wheel to be adjusted according to the position of the burrs, making it easier to grind burrs at different angles and improving the practicality of the equipment.

[0023] Secondly, the mounting cylinder 107 is fixedly connected to the mounting base 102 and is located on the side of the mounting base 102 away from the worktable 100; the drive rod 108 is slidably connected to the mounting cylinder 107 and is located on the side of the mounting cylinder 107 away from the mounting base 102, and is connected to the mounting bracket 103. The mounting cylinder 107 is bolted to the top of the mounting base 102, and the mounting base 102 makes the mounting cylinder 107 more stably mounted on the worktable 100. The drive rod 108 is slidably mounted on the inner side of the mounting cylinder 107, allowing the drive rod 108 to slide up and down within the mounting cylinder 107. One end of the drive rod 108 is connected to the mounting bracket 103 by a bolt, enabling the drive rod 108 to drive the mounting bracket 103 to move up and down. A hydraulic rod is mounted on the inner side of the mounting cylinder 107 to drive the drive rod 108, thereby driving the drive rod 108 to move and in turn enabling the drive rod 108 to drive the mounting bracket 103 to move.

[0024] Meanwhile, the rotating ring 109 is fixedly connected to the rotating shaft 104 and is located on the side of the rotating shaft 104 away from the mounting bracket 103; the mounting shell 110 is fixedly connected to the mounting bracket 103 and is located on the side of the mounting bracket 103 close to the rotating ring 109; the limiting element is installed on the mounting shell 110, and the limiting element restricts the rotation of the rotating shaft 104; the rotating ring 109 is installed on the side of the rotating shaft 104 away from the mounting bracket 103 by bolts, and the rotating ring 109 drives the shaft to rotate. The rotating shaft 104 is rotated, which in turn causes the rotating block 105 to rotate, thereby changing the angle of the grinding wheel 106. The mounting shell 110 is bolted to the mounting bracket 103 on the side near the rotating ring 109, and the rotating shaft 104 passes through the mounting shell 110. The limiting element is installed on the mounting shell 110 to restrict the rotation of the rotating shaft 104, thereby preventing the rotating shaft 104 from rotating during equipment use and ensuring the stability of the equipment.

[0025] Additionally, the limiting block 111 is fixedly connected to the rotating shaft 104 and located at one end of the rotating shaft 104 near the mounting housing 110; the telescopic rod 112 is fixedly connected to the mounting housing 110 and located on the side of the mounting housing 110 away from the limiting block 111; the locking block 113 is fixedly connected to the telescopic rod 112 and located on the side of the telescopic rod 112 away from the mounting housing 110, and engages with the limiting block 111; the driving component is mounted on the locking block 113, and the driving component drives the locking block 113 to move; the limiting block 111 is bolted to the side of the rotating shaft 104 near the mounting housing 110, and the limiting block 111 fixes the rotating shaft 104, thereby allowing the rotating shaft 104 to move. Shaft 104 stops rotating. One end of the telescopic rod 112 is bolted to the side of the mounting housing 110 away from the limiting block 111. The locking block 113 is bolted to the other end of the telescopic rod 112. The locking block 113 abuts against the mounting housing 110, allowing the locking block 113 to slide on the mounting housing 110. The mounting housing 110 has a sliding groove that mates with the locking block 113, so that the locking block 113 can stably engage with the limiting block 111, thereby fixing the limiting block 111 and thus fixing the rotating shaft 104. The driving component is mounted on the locking block 113, and the driving component drives the locking block 113 to move, thereby engaging the locking block 113 with the limiting block 111.

[0026] Finally, the spring 114 is sleeved on the outside of the telescopic rod 112, with its two ends abutting against the locking block 113 and the mounting shell 110, respectively; the moving block 115 is fixedly connected to the locking block 113 and located on the side of the locking block 113 away from the telescopic rod 112, with the spring 114 sleeved on the outside of the telescopic rod 112, and its two ends abutting against the locking block 113 and the mounting shell 110, respectively. The spring 114's elasticity... The force drives the locking block 113 to move, thereby engaging the locking block 113 with the limiting block 111, thus fixing the rotating shaft 104. The moving block 115 is bolted to the locking block 113. The moving block 115 drives the locking block 113 to move against the elastic force of the spring 114, thereby causing the locking block 113 to move away from the limiting block 111. This allows the rotating ring 109 to drive the rotating shaft 104 to rotate, thereby changing the angle of the grinding wheel 106.

[0027] Using the automotive parts grinding fixture of this embodiment, when it is necessary to change the angle of the grinding wheel 106, the moving block 115 drives the locking block 113 to move, causing the locking block 113 to move away from the limiting block 111. At this time, the rotating ring 109 drives the rotating shaft 104 to rotate, which in turn drives the grinding wheel 106 to rotate through the rotating block 105. When the grinding wheel 106 rotates to a suitable angle, the moving block 115 is released, and the spring 114 drives the locking block 113 to move, thereby engaging the locking block 113 with the limiting block 111, thus fixing the rotating shaft 104. This allows the grinding wheel 106 to grind burrs at different angles, thereby enabling the angle of the grinding wheel to be adjusted according to the position of the burr, facilitating the grinding of burrs at different angles, and improving the practicality of the equipment.

[0028] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
