Abstract
Description
Technical Field
[0001] This utility model relates to the field of guide rail processing technology, specifically a grinding fixture for processing linear guide rail sliders. Background Technology
[0002] The slider of a linear guide is a basic component used to support and guide moving parts to reciprocate linearly in a given direction on the guide rail. The slider is usually made of high-strength, high-hardness materials, such as bearing steel, to ensure its wear resistance and load-bearing capacity.
[0003] In the production process of linear guide sliders, the slider body needs to be ground, especially to remove burrs, unevenness and machining marks on the inner hole of the slider (the inner hole has an opening and the arc angle is greater than 180°). However, most grinding machines at present are designed with traditional structure, which is not convenient for positioning multiple sliders at the same time. Therefore, the grinding head is generally used to grind the inner hole of a single slider at the station. It is not convenient to grind the annular inner wall of multiple sliders at the same time, resulting in low actual grinding efficiency and being detrimental to the production efficiency of enterprises. Utility Model Content
[0004] To address the technical problems existing in the background art, this utility model proposes a grinding fixture for machining linear guide sliders.
[0005] This utility model proposes a grinding fixture for processing linear guide sliders, including a grinding machine, a first pusher, and a support plate. The support plate has a positioning groove adapted to the slider body. The number of positioning grooves is multiple and they are evenly arranged along the length direction of the support plate. The slider body is placed in the positioning groove and fastened by fasteners.
[0006] The support plate is installed on the movable end of the first pusher. The first pusher drives the support plate to move to the grinding machine, so that the grinding machine can grind multiple slider bodies at the same time.
[0007] As a further optimization of this utility model, the grinding machine includes a grinding head, a grinding machine base, and a second pusher. The grinding head is rotatably mounted on the grinding machine base and is driven to rotate by a drive component inside the grinding machine base. The grinding machine base is mounted on the movable end of the second pusher. The second pusher drives the grinding machine base to move, so that the grinding machine base drives the grinding head to insert into the annular inner hole of the slider body for grinding operations.
[0008] As a further optimization of this utility model, the first pusher is disposed on the side of the grinding machine base, and the pushing direction of the first pusher is perpendicular to the pushing direction of the second pusher.
[0009] As a further optimization of this utility model, the number of grinding heads is multiple, and the multiple grinding heads are evenly distributed along the length direction of the grinding machine base and correspond one-to-one with multiple positioning slots.
[0010] As a further optimization of this utility model, the axis of the grinding head coincides with the axis of the inner hole of the slider body in the positioning groove.
[0011] As a further optimization of this utility model, an arc-shaped groove is provided in the middle of the bottom surface of the inner cavity of the positioning groove. The arc-shaped groove is adapted to the annular inner hole opening at the bottom of the slider body. When the slider body is placed in the positioning groove, the annular inner hole of the slider body and the arc-shaped groove form a complete ring.
[0012] As a further optimization of this utility model, the positioning groove has a first opening on the side near the upper surface of the support plate for placing and removing the slider body, and the positioning groove has a second opening on the side near the left and right end faces of the support plate for the grinding machine to insert the workpiece for grinding operations, and the second opening is a fully enclosed structure.
[0013] As a further optimization of this utility model, the inner wall of the positioning groove on both sides of the second opening is divided into three continuous sections. The three sections of the inner wall are respectively set as a first side, a second side, and a third side. The first side is set on the side close to the first opening, the second side is set on the side close to the bottom surface of the positioning groove, and the third side is set between the first side and the second side and forms a stepped shape that matches the top of both sides of the slider body.
[0014] As a further optimization of this utility model, the first pusher is a linear electric slide rail, and the slide groove and the movable end of the linear electric slide rail are both arranged facing upwards. The bearing plate is installed on the movable end of the linear electric slide rail, and a guide block is provided on the outside of the slide groove of the linear electric slide rail. The side of the guide block away from the slide groove is an inclined surface, and the bottom end of the inclined surface is aligned with the edge of the upper end face of the linear electric slide rail.
[0015] As a further optimization of this utility model, a pressure plate is hinged to one end of the bearing plate, the free end of the pressure plate presses over the positioning groove and is fixed to the other end of the bearing plate by fasteners, and an anti-slip pad is installed on the lower end surface of the pressure plate, the anti-slip pad being in close contact with the upper end surface of the slider body.
[0016] The grinding fixture for machining linear guide sliders proposed in this utility model has the following beneficial effects:
[0017] This invention features multiple positioning slots on a support plate that are adapted to the slider body, allowing multiple slider bodies to be placed simultaneously. The support plate is then pushed to the grinding machine by a first pusher. The grinding machine's multiple grinding heads correspond one-to-one with the positioning slots, enabling the grinding of multiple slider bodies simultaneously. Compared to the traditional single-slider grinding method, this significantly improves grinding efficiency and helps enhance enterprise production benefits.
[0018] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0027] Please see Figure 1 A grinding fixture for processing linear guide sliders includes a grinding machine, a first pusher 2, and a support plate 3. The support plate 3 has a positioning groove 4 that is adapted to the slider body 5. There are multiple positioning grooves 4 and they are evenly arranged along the length direction of the support plate 3. The slider body 5 is placed in the positioning groove 4 and fastened by fasteners.
[0028] The support plate 3 is installed on the movable end of the first pusher 2. The first pusher 2 drives the support plate 3 to move to the grinding machine, so that the grinding machine grinds multiple slider bodies 5 at the same time.
[0029] The support plate 3 serves as the base component for placing the slider body 5. Multiple positioning slots 4 on the support plate 3 are adapted to the slider body 5. After the slider body 5 is placed into the positioning slot 4, it is fixed by fasteners to ensure that the slider body 5 is in a stable position on the support plate 3. The movable end of the first pusher 2 is connected to the support plate 3. When the first pusher 2 is started, it generates driving force to drive the support plate 3 to move along a specific direction. During the movement, multiple slider bodies 5 on the support plate 3 move together until they reach the position of the grinding machine. At this time, the grinding machine starts to work and grinds multiple slider bodies 5 at the same time.
[0030] The design of multiple positioning slots 4 allows multiple slider bodies 5 to be placed at one time, enabling multiple sliders to be processed simultaneously, which greatly improves processing efficiency. The positioning slots 4 are compatible with the slider bodies 5 and are fastened by fasteners, ensuring the stability of the sliders during transportation and processing and improving processing accuracy.
[0031] Specifically, such as Figure 1 As shown, the grinding machine includes a grinding head 1, a grinding machine base 8, and a second pusher 9. The grinding head 1 is rotatably mounted on the grinding machine base 8 and is driven to rotate by the driving component inside the grinding machine base 8. The grinding machine base 8 is mounted on the movable end of the second pusher 9. The second pusher 9 drives the grinding machine base 8 to move, so that the grinding machine base 8 drives the grinding head 1 to insert into the annular inner hole of the slider body 5 for grinding operations.
[0032] After the drive unit inside the grinding machine base 8 is started, it generates power to make the grinding head 1 rotate around its own axis. At the same time, the second pusher 9 starts to work, and its movable end drives the grinding machine base 8 mounted on it to move. As the grinding machine base 8 moves, the rotating grinding head 1 also moves and finally accurately inserts into the annular inner hole of the slider body 5. During the process of the grinding head 1 being inserted into the inner hole, its high-speed rotation grinds the burrs, unevenness and machining marks on the inner wall of the slider body 5.
[0033] This structural design enables automatic insertion and grinding of the grinding head 1, reducing manual intervention and improving the accuracy and stability of grinding. Furthermore, the simultaneous grinding of multiple slider bodies 5 further enhances processing efficiency.
[0034] Specifically, such as Figure 1 As shown, the first pusher 2 is disposed on the side of the grinding machine base 8, and the pushing direction of the first pusher 2 is perpendicular to the pushing direction of the second pusher 9.
[0035] The first pusher 2 is responsible for pushing the support plate 3 and the slider body 5 longitudinally to the left side of the grinding machine. The second pusher 9 moves in a direction perpendicular to the first pusher 2, pushing the grinding machine base 8 with the grinding head 1 installed to the left to the position corresponding to the inner hole of the slider body 5. This layout makes the movements of the two pushers independent yet coordinated, accurately controlling the relative position of the slider body 5 and the grinding head 1.
[0036] The design of two pushers pushing in different directions avoids interference between moving parts, improves the stability and reliability of equipment operation, and precise position control helps to improve grinding accuracy.
[0037] Specifically, such as Figure 1 As shown, there are multiple grinding heads 1, which are evenly distributed along the length of the grinding machine base 8 and correspond one-to-one with multiple positioning slots 4.
[0038] When the bearing plate 3 is pushed to the grinding machine by the first pusher 2, and the second pusher 9 drives the grinding machine base 8 to move, each grinding head 1 can accurately align with and insert into the annular inner hole of the slider body 5 in the corresponding positioning groove 4. Multiple grinding heads 1 rotate simultaneously to perform grinding operations, processing the inner holes of multiple slider bodies 5 at the same time, realizing simultaneous grinding of multiple sliders, which greatly improves grinding efficiency. The uniformly distributed design ensures that each slider can obtain the same quality of grinding processing, ensuring the consistency of the inner wall size and shape of each slider, thereby improving production quality.
[0039] Furthermore, the axis of the grinding head 1 coincides with the axis of the inner hole of the slider body 5 in the positioning groove 4;
[0040] During the equipment installation and commissioning phase, precise measurements and adjustments are made to ensure that the axis of the grinding head 1 coincides with the axis of the inner hole of the slider body 5 in the positioning groove 4. When the second pusher 9 moves the grinding machine base 8 to bring the grinding head 1 close to the inner hole of the slider body 5, the grinding head 1 can smoothly and accurately insert into the annular inner hole of the slider body 5 due to the axis coincidence. During the grinding process, because the axis coincides, the grinding head 1 grinds the inner wall of the slider body 5 more evenly and will not have uneven grinding. This ensures that the grinding head 1 is subjected to uniform force during the grinding process, greatly improves the grinding accuracy, reduces the processing error caused by the misalignment of the grinding head 1 and the inner hole, and ensures the grinding quality of the inner hole of the slider body 5.
[0041] Specifically, such as Figures 2-4 As shown, an arc-shaped groove 10 is provided in the middle of the bottom surface of the inner cavity of the positioning groove 4. The arc-shaped groove 10 is adapted to the annular inner hole opening at the bottom of the slider body 5. When the slider body 5 is placed in the positioning groove 4, the annular inner hole of the slider body 5 and the arc-shaped groove 10 form a complete ring.
[0042] The fit between the arc groove 10 and the inner hole at the bottom of the slider body 5 helps the grinding head 1 to better grind the entire inner hole wall, enhances the stability of the slider body 5 during the grinding process, improves grinding accuracy, and enhances grinding quality.
[0043] Specifically, such as Figure 4 As shown, the positioning groove 4 has a first opening on the side near the upper end face of the support plate 3 for placing and removing the slider body 5. The positioning groove 4 has a second opening on the side near the left and right end faces of the support plate 3 for the grinding machine to insert the workpiece for grinding. The second opening is a fully enclosed structure.
[0044] The first opening facilitates the operator to place the slider body 5 into the positioning groove 4, and to remove the slider body 5 from the positioning groove 4 after grinding, thus improving the convenience of operation.
[0045] The second opening is used for the grinding head 1 of the grinding machine to extend into for grinding operations. Its fully enclosed structure means that there is still a portion of the supporting plate 3 between the second opening and the first opening, which facilitates the insertion and positioning of the slider body 5, improves the convenience and safety of operation, and ensures that the grinding head 1 can accurately perform grinding operations.
[0046] Furthermore, the inner wall of the positioning groove 4 on both sides of the second opening is divided into three continuous sections. The three sections of the inner wall are respectively set as a first side 41, a second side 42, and a third side 43. The first side 41 is located on the side close to the first opening, the second side 42 is located on the side close to the bottom surface of the positioning groove 4, and the third side 43 is located between the first side 41 and the second side 42 and forms a stepped shape that matches the top of both sides of the slider body 5.
[0047] When the slider body 5 is placed in the positioning groove 4, the top of both sides of the slider body 5 fits tightly with the stepped structure of the third side 43. The first side 41 and the second side 42 limit the slider body 5 from different directions. During the grinding process, this special inner wall structure design can effectively limit the position of the slider body 5 in the positioning groove 4, prevent the slider body 5 from shifting or shaking, ensure the grinding accuracy, further improve the positioning accuracy and stability of the slider body 5 in the positioning groove 4, ensure the quality of the grinding process, and reduce the processing error caused by slider displacement.
[0048] Specifically, such as Figure 1 As shown, the first pusher 2 is a linear electric slide rail, and the slide groove and the movable end of the linear electric slide rail are both set upwards. The bearing plate 3 is installed on the movable end of the linear electric slide rail, and a guide block 7 is provided on the outside of the slide groove of the linear electric slide rail. The side of the guide block 7 away from the slide groove is an inclined surface, and the bottom end of the inclined surface is aligned with the edge of the upper end face of the linear electric slide rail.
[0049] After the linear electric slide rail is powered on, the internal drive device causes the movable end to move in a specific direction within the slide groove, thereby driving the bearing plate 3 installed on the movable end to move. The guide block 7 is set outside the slide groove and symmetrically distributed so as to discharge the grinding waste outward.
[0050] It should be noted that after grinding is completed, after the grinding head 1 is pulled out of the inner hole of the slider body 5, the inner hole of the slider body 5 needs to be blown by the air blowing assembly in order to remove grinding waste.
[0051] Specifically, such as Figure 1 and Figure 2 As shown, a pressure plate 6 is hinged to one end of the bearing plate 3. The free end of the pressure plate 6 presses over the positioning groove 4 and is fixed to the other end of the bearing plate 3 by fasteners. An anti-slip pad 11 is installed on the lower end face of the pressure plate 6. The anti-slip pad 11 is in close contact with the upper end face of the slider body 5.
[0052] After placing the slider body 5 in the positioning groove 4, rotate the pressure plate 6 so that its free end covers the top of the positioning groove 4. Then use fasteners to fix the pressure plate 6 to the other end of the bearing plate 3. At this time, the anti-slip pad 11 on the lower end face of the pressure plate 6 is in close contact with the upper end face of the slider body 5. The anti-slip pad 11 increases the friction between the pressure plate 6 and the slider body 5, preventing the slider body 5 from moving upward or displacing due to grinding force or vibration during the grinding process.
[0053] This further enhances the fixing effect on the slider body 5, ensures the stability of the slider body 5 during the grinding process, improves the grinding accuracy, and the anti-slip pad 11 can also prevent damage caused by direct contact between the pressure plate 6 and the slider body 5.
[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
