Description

Technical Field

[0001] This utility model relates to the field of grinding fixtures, specifically to a multi-station high-efficiency grinding fixture. Background Technology

[0002] Currently, most parts of many machines require mold processing, and some molds require both square feet and round feet (cylindrical feet). To ensure mold accuracy, the round feet must be processed to ensure that their height is within ±0.1mm of the square feet to ensure levelness.

[0003] Currently, when processing the two types of feet, the larger square feet are ground on a large grinding machine, while the cylindrical feet need to be processed on a smaller grinding machine. This process may result in the height of the two types of feet exceeding ±0.1 mm, compromising mold quality. If both types of feet are processed on a large grinding machine, the round feet tend to wobble during grinding, making it difficult to fix them firmly on the grinding table. This prevents both types of feet from being processed in a single operation, impacting the overall mold manufacturing efficiency.

[0004] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0005] The purpose of this invention is to provide a multi-station, high-efficiency grinding fixture.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A multi-station high-efficiency grinding fixture, as a component for clamping multiple round pads, is placed on the magnetic table of a grinding machine for processing square pads. The grinding fixture includes a positioning frame, which has at least one frame groove penetrating its own upper and lower surfaces. The height of the frame groove and the positioning frame are the same as the height of the square pad.

[0008] The frame groove includes a square groove, one end of which extends outward and gradually tapers inward to form a triangular groove. The width of the square groove and the triangular groove is an integer multiple of the diameter of the round pad. The square groove and the triangular groove serve as components for positioning at least three round pads.

[0009] A foot fixing block is provided at the other end of the square groove. The foot fixing block is driven linearly to push each round foot towards the triangular groove side, so that the round foot located at the rear end of the push abuts against the triangular groove wall of the triangular groove, and each round foot is limited in the horizontal direction.

[0010] Preferably, the shape and size of the positioning frame are the same as those of the square pad.

[0011] Preferably, the inner corners of both the triangular groove and the square groove are rounded.

[0012] Preferably, the foot fixing block includes at least one pointed support portion, one end face of which at the center of the frame groove is a triangular face, which corresponds to the gap between two adjacent circular feet, and the triangular face of the foot fixing block driven by a linear motion abuts against the cylindrical face of the two adjacent circular feet.

[0013] Preferably, the linear drive includes a screw, one end of which passes through the positioning frame and extends into the frame groove, and the screw is threadedly connected to the positioning frame.

[0014] More preferably, the screw is disposed separately from the foot fixing block, and the foot fixing block includes a flat surface that fits against the inner wall of the square groove for abutting the screw.

[0015] More preferably, the screw and the foot fixing block are rotatably connected as one unit through a bearing.

[0016] The working principle and advantages of this utility model are as follows:

[0017] This utility model utilizes a positioning frame with the same height as the square pad to frame each round pad. The positioning frame has a square groove and a triangular groove. The triangular groove and the pad fixing block with a pointed support can clamp several round pads on the inner side from both ends, preventing the round pads from shaking during grinding and ensuring stable grinding. Moreover, the round pads and square pads can be processed to the same height at the same time, which not only improves the mold accuracy but also greatly improves the processing efficiency.

[0018] This utility model has a simple structure. The positioning frame can be obtained by directly slotting a pre-made square pad, which is locally sourced, easy to process, and reduces the cost of fixtures. Attached Figure Description

[0035] See appendix Figure 1-7As shown, a multi-station high-efficiency grinding fixture is used as a component for clamping multiple round pads. The grinding fixture is placed on the magnetic table of a grinding machine for processing square pads. The grinding fixture includes a positioning frame 1, which has at least one frame groove 2 that runs through its upper and lower surfaces. The height of the frame groove 2 and the positioning frame 1 are the same as the height of the square pad.

[0036] The frame groove 2 includes a square groove 21, one end of which extends outward and gradually tapers inward to form a triangular groove 22. The width of the square groove 21 and the triangular groove 22 is an integer multiple of the diameter of the round pad foot to prevent the round pad foot from swaying left and right in the groove. The square groove 21 and the triangular groove 22 serve as components for positioning at least three round pad feet.

[0037] A foot fixing block 3 is provided at the other end of the square groove 21. The foot fixing block 3 is driven linearly to push each round foot towards the triangular groove 22, so that the round foot located at the rear end of the push abuts against the triangular groove wall of the triangular groove 22, and each round foot is limited in the horizontal direction.

[0038] In this embodiment, the round pads are placed in the slot 2 of the positioning frame 1, and the pad fixing block 3, in conjunction with the triangular groove wall of the triangular groove 22, can simultaneously fix and limit several round pads. During grinding, the positioning frame 1 with the round pads fixed can be placed together with the square pads on the magnetic table of the large grinding machine. The magnetic table will attract and fix the square pads, the positioning frame 1, and the round pads in the positioning frame 1. At this time, the lower end surfaces of the square pads and the round pads are coplanar, thereby ensuring that the upper ends of the square pads and the round pads are ground flat to the same height, ensuring that the height of the pads is consistent.

[0039] In this embodiment, the positioning frame 1 has the same shape and size as the square pad. Specifically, the positioning frame 1 can be directly cut into the pre-processed square pad, making it easy to use locally and reducing costs. This arrangement facilitates use on a large grinding machine. Specifically, the positioning frame 1 and the square pad can be arranged in sequence against the magnetic table of the large grinding machine. The square pad and the positioning frame 1 can abut against each other and limit each other, resulting in higher stability and facilitating the movement of the grinding disc for grinding.

[0040] In addition, when there is only one type of clamping device on the grinding machine magnetic table, when the positioning frame 1 and the square pad with the same appearance and size are clamped, there is no need to adjust the clamping stroke of the clamping device to adapt to the positioning frame 1 and the square pad, thus improving versatility.

[0041] In this embodiment, to avoid wear on the cylindrical surface of the round pad, the inner corners of the triangular groove 22 and the square groove 21 are both rounded.

[0042] In this embodiment, the foot fixing block 3 includes at least one pointed support portion 31. One end face of the pointed support portion 31 located at the center of the frame groove 2 is a triangular face, which corresponds to the gap between two adjacent circular feet. The triangular face of the foot fixing block 3, driven linearly, abuts against the cylindrical surfaces of the two adjacent circular feet. The pointed support portion 31 can secure the circular feet more firmly.

[0043] like Figure 4-6 The image shows three round pads placed inside the frame groove 2. One of the round pads is in contact with the two walls of the triangular groove 22, and the other two round pads are in contact with the two side walls of the square groove 21. At this time, there is one tip support 31, which corresponds to the gap between the two round pads in the square groove 21.

[0044] like Figure 7 The image shows five round pads placed inside the frame groove 2. Two of the round pads are in contact with the two walls of the triangular groove 22, and the other three round pads are arranged in a straight line with the round pads on both sides in contact with the two walls of the square groove 21. At this time, there are two tip support parts 31, which correspond to the two gaps between the three round pads in the square groove 21.

[0045] In this embodiment, as Figure 1-7 As shown, the linear drive includes a screw 4, one end of which passes through the positioning frame 1 and extends into the frame groove 2. The screw 4 is threadedly connected to the positioning frame 1. The screw 4 is separately disposed from the foot fixing block 3. The foot fixing block 3 includes a flat surface 32 that conforms to the inner wall of the square groove 21 for abutting against the screw 4.

[0046] When adjusting the foot fixing block 3, simply tighten the screw 4 to push the foot fixing block 3, which will push several round feet against the side of the triangular groove 22.

[0047] The foot fixing block 3 and screw 4 are set separately, which facilitates processing and assembly.

[0048] In other embodiments, to prevent the foot fixing block 3 from being lost, the screw 4 and the foot fixing block 3 are rotatably connected as one unit through a bearing, so as not to affect the screw 4 driving the foot fixing block 3 to move linearly.

[0049] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
