[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0030] Reference Figure 1 and Figure 2 The utility model provides an embodiment of a ball head grinding jig for parts production, comprising a base 1, which is fixedly mounted on a workbench by bolts to position the device. The top of the base 1 is provided with slots and multiple groups for inserting fixed blocks 1 2 and fixed blocks 2 3, so that they can be quickly positioned. A fixed block 1 2 is provided on the right side of the top of the base 1, and a fixed block 2 3 is provided on the left side of the top of the base 1. The fixed block 1 2 and the fixed block 2 3 work together to clamp and fix the parts that need to be ball head ground. A threaded rod is threadedly connected to the left side of the fixed block 2 3, and a movable block is rotatably connected to the right side of the threaded rod. The movable block slides on the inner wall of the fixed block 2 3, and the ball head is clamped by cooperating with the threaded rod and the movable block and the fixed block 1 2. A fixing assembly is provided on the inner wall of the base 1, and the fixing assembly includes a fixing rod 41. The fixing rod 41 is inserted into the inner wall of the slot at the top of the base 1 to provide support and positioning for the fixed block 2 3. The top of the fixing rod 41 is fixedly connected to the bottom end of the fixed block 2 3. A slot 42 is provided on the right side of the lower part of the fixing rod 41 to cooperate with the limit block 44. When the left side of the limit block 44 is inserted into the inner wall of the slot 42, the fixing rod 41 is fixed, thereby fixing the fixed block 2 3 and the fixed block 1 2 to the base 1.
[0031] The two-way threaded rod 43 is connected to the inner wall of the slot by rotation, and the inner wall of the base 1 is rotatably connected to the two-way threaded rod 43. The outer side of the two-way threaded rod 43 passes through a threaded limit block 44, and the limit block 44 is provided with two groups, which are symmetrically arranged. By rotating the two-way threaded rod 43, the two groups of limit blocks 44 can be driven to move left and right, so that they can be inserted into or disengaged from the slot 42, thereby achieving rapid fixation and unlocking of multiple groups of fixing rods 41. The left side of the limit block 44 is inserted into the inner wall of the slot 42, and the bottom end of the fixing block 2 3 is fixedly connected to the right side of the fixing rod 41 near the fixing rod 41. The positioning pin 45 is inserted into the inner wall of the slot to further enhance the stability and accuracy of the connection between the fixing block 2 3 and the base 1. An anti-loosening component is provided on the rear side of the two-way threaded rod 43, and the anti-loosening component includes a pull sleeve 51. By pulling the pull sleeve 51, the limit tooth 52 can be inserted into or disengaged from the limit groove 53 on the base 1, thereby achieving anti-loosening locking and unlocking of the two-way threaded rod 43, and the inner wall of the pull sleeve 51 is slidably connected to the outer side of the two-way threaded rod 43.
[0032] Furthermore, the left side of the limit block 44 is set to a concave shape, which increases the release area with the slot 42, enables it to better cooperate with the slot 42, and improves the stability of the fixation. There are multiple groups of fixing rods 41 and positioning pins 45, and the multiple groups of fixing rods 41 and positioning pins 45 are symmetrically arranged at the bottom end of the fixing block 2, which can fix the fixing block 2 and the fixing block 3 at the same time, thereby improving the installation or maintenance efficiency. The rear side of the two-way threaded rod 43 is fixedly connected to the limiting plate 46 for limiting the pull sleeve 51.
[0033] Reference Figure 2 and Figure 3 The anti-loosening component also includes a limiting tooth 52, which is provided with multiple groups. When inserted into the inner wall of the limiting groove 53 on the base 1, the rotation of the two-way threaded rod 43 is restricted to prevent the two-way threaded rod 43 from loosening due to vibration or other external forces, thereby ensuring the stability of the fixing component. The limiting tooth 52 is fixedly connected to the front side of the pull sleeve 51, and a limiting groove 53 is provided on one side of the base 1 close to the pull sleeve 51. There are multiple groups of limiting teeth 52 that cooperate with the limiting teeth 52 to limit the rotation of the two-way threaded rod 43. The limiting tooth 52 is inserted into the inner wall of the limiting groove 53, and the rear inner wall of the pull sleeve 51 slides on the outside of the limiting plate 46. The top of the limiting plate 46 is provided with a guide groove 56, which cooperates with the protrusion. When the protrusion slides out of the guide groove 56, the pull sleeve 51 is rotated to make the protrusion slide on the outside of the limiting plate 46, thereby limiting the pull sleeve 51, making it convenient for the operator to rotate the two-way threaded rod 43.
[0034] Furthermore, a protrusion is provided on the inner wall of the pull sleeve 51 for limiting the position of the pull sleeve 51. The protrusion slides on the inner wall of the guide groove 56. A baffle 54 is slidably connected to the outer side of the bidirectional threaded rod 43. The baffle 54 is driven by the pull sleeve 51 to squeeze the compression spring 55, providing elastic force for the pull sleeve 51 so that the pull sleeve 51 can be reset. At the same time, the limiting tooth 52 on the pull sleeve 51 is stably inserted into the inner wall of the limiting groove 53, thereby improving the stability of the pull sleeve 51. The baffle 54 slides on the inner wall of the pull sleeve 51. The baffle 54 and the limiting plate 46 are elastically connected by the compression spring 55. The elastic force of the compression spring 55 makes the compression spring 55 push the baffle 54 to reset the pull sleeve 51, and the limiting tooth 52 is disengaged from the inner wall of the limiting groove 53. An anti-slip strip is provided on the outside of the pull sleeve 51 to increase friction and facilitate the operator to pull the pull sleeve 51.
[0035] Working principle: During use, when it is necessary to maintain or install the fixed block 2 3 and the fixed block 1 2, pull the pull sleeve 51 to make the protrusion slide out of the guide groove 56. When pulling the pull sleeve 51, the pull sleeve 51 drives the baffle 54 to move, squeezing the compression spring 55, and then rotate the pull sleeve 51 to make the protrusion slide on the outside of the limit plate 46, thereby limiting the pull sleeve 51 and making the limit tooth 52 disengage from the inner wall of the limit groove 53, making it convenient for the operator to rotate the two-way threaded rod 43.
[0036] At this time, the two-way threaded rod 43 is rotated to drive the two sets of limit blocks 44 to move in opposite directions, so that the two sets of limit blocks 44 are inserted into the slots 42 of the fixed rod 41, or disengaged from the slots 42, thereby limiting or releasing the limit of the fixed rod 41. At this time, the limit of the fixed block 2 3 and the fixed block 1 2 is released or released, and the fixed block 2 3 and the fixed block 1 2 can be taken out of or installed from the slots on the base 1, and the fixed block 2 3 and the fixed block 1 2 can be maintained or installed, thereby improving the maintenance efficiency of the device.
[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
