Description

Technical Field

[0001] This invention relates to a quartz processing technology, and more specifically, to a quartz support processing fixture. Background Technology

[0002] Quartz products are widely used in many fields due to their superior performance. Quartz supports are mainly used in four-axis machining centers for grinding, primarily serving to support silicon wafers. Therefore, high requirements are placed on the flatness and parallelism between quartz supports. Secondly, quartz supports have several positioning holes, with a positional accuracy requirement of 0.02. Furthermore, the overall structure of the quartz support is complex, with a large height difference, and is characterized by its thinness, height, and brittleness, making it difficult to process. The quartz support has three support arms and one rod. From a manufacturing perspective, the three support arms and the rod are machined separately, then welded and subjected to precision annealing. Due to the characteristics of the process, the product is prone to deformation during precision annealing and precision annealing, resulting in dimensional deviations. If the support arms and rod are first welded and precision annealed before being assembled together for cold working, the structural characteristics of the entire product pose risks of inaccurate positioning, difficulty in dimensional control, and damage / breakage during processing. Summary of the Invention

[0003] To overcome the above shortcomings, the present invention provides a quartz holder processing fixture, which realizes the clamping and positioning of the quartz holder with accurate and reliable positioning, ensuring the processing accuracy of the quartz holder and preventing damage or breakage during processing.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a quartz bracket processing fixture, comprising a reference ring and a fixing plate, the fixing plate being installed on the reference ring and connected to a positioning seat; the quartz bracket comprising a rod body and a plurality of support arms connected to the rod body; the positioning seat having a support surface corresponding to the support arms, the support arms abutting against the support surface, the positioning seat having a circumferential fixing post and a circumferential movable block, the circumferential fixing post and the circumferential movable block abutting against both sides of the support arm to circumferentially position the support arm; the fixing plate having a positioning groove, the rod body being adapted to the positioning groove, and a pressure plate connected to the fixing plate, the pressure plate pressing against the rod body.

[0005] The quartz holder is mounted on the fixture. Positioning grooves on the fixing plate support and position the rod of the quartz holder, while a pressure plate clamps the rod. The support arm of the quartz holder rests against the support surface on the positioning seat, providing a large support area and stable, reliable support, thus preventing vibration during product processing. The fixing plate is mounted on a reference ring, which is then installed on the processing equipment for easy centering, reducing manual calibration time.

[0006] The quartz holder processing fixture of this application enables the clamping and positioning of the quartz holder with precise and reliable positioning, ensuring the processing accuracy of the quartz holder and preventing damage or breakage during processing.

[0007] Preferably, bosses are provided at both ends of the fixing plate, and positioning grooves are provided on the two bosses.

[0008] The protrusions at both ends of the fixing plate leave a gap in the middle section, reducing errors caused by contact with the rod and also reducing the weight of the fixing plate.

[0009] Preferably, a V-shaped groove is provided on the lower surface of the pressure plate.

[0010] The V-shaped groove reduces the contact area between the pressure plate and the rod, thereby reducing the risk of scratching the surface of the rod.

[0011] Preferably, the positioning base and each support arm are provided with several clearance slots.

[0012] The clearance groove provides space for machining countersunk holes on the support arm, thus avoiding interference.

[0013] Preferably, a fixed block is provided on the positioning seat corresponding to the circumferential movable block, and an adjusting screw is provided on the fixed block to connect with the circumferential movable block. The distance between the fixed block and the circumferential movable block is adjusted by rotating the adjusting screw.

[0014] After the quartz bracket is in place, turn the adjusting screw to move the circumferential movable block, so that the circumferential movable block is pressed against the side wall of the support arm to achieve circumferential positioning of the support arm.

[0015] Preferably, the positioning seat is provided with a through hole, through which the rod passes.

[0016] The through hole facilitates the loading of the rod.

[0017] Preferably, the positioning base and the fixing plate are provided with corresponding slots, and the end of the fixing plate is fitted into the slot.

[0018] The end of the fixing plate is inserted into the slot on the positioning seat, making the connection convenient and reliable.

[0019] Preferably, a positioning groove is provided on the lower surface of the fixing plate, the side wall of the positioning groove has an arc structure, the upper end of the reference ring is adapted to the positioning groove, and the side wall of the positioning groove is adapted to fit the outer wall of the reference ring.

[0020] The reference ring and the positioning groove are matched to ensure the accuracy of the connection position between the fixing plate and the reference ring.

[0021] Preferably, a threaded sleeve is provided around the through hole on the positioning seat, and several clearance notches are provided on the threaded sleeve corresponding to the support arm. A sliding sleeve is installed inside the through hole, and several push rods are evenly distributed on the sliding sleeve, extending into the threaded sleeve. A return spring is installed between the sliding sleeve and the positioning seat. Several adjusting rods are evenly hinged on the inner wall of the through hole, with one end of the adjusting rod located near the outer wall of the rod body. The adjusting rod has a long groove, and a connecting post is provided on the push rod, connecting the connecting post to the long groove. A rotating post is threadedly connected to the threaded sleeve, and a pressure post is connected to the rotating post. A buffer spring is installed between the pressure post and the rotating post. The end of the rotating post rests on the push rod, and the end of the pressure post rests on the end face of the rod body.

[0022] After the quartz holder's rod passes through the through hole, it is supported in the positioning groove. Then, the rotating column is installed into the threaded sleeve. As the rotating column rotates, the end of the pressure column presses against the end face of the rod, thereby adjusting the axial position of the rod and ensuring that the support arm reliably fits against the support surface. Simultaneously, the rotating column presses against the top rod, and the top rod moves, driving the adjusting rod to rotate. This causes the ends of several evenly distributed adjusting rods to simultaneously press against the outer wall of the rod, precisely positioning the rod and ensuring the accuracy of its axial position. Finally, the pressure plate and circumferential movable block are connected to achieve reliable clamping of the quartz holder. This structural design makes the clamping of the quartz holder by the fixture more precise and reliable.

[0023] Compared with the prior art, the beneficial effects of the present invention are: (1) The quartz bracket processing fixture of this application realizes the clamping and positioning of the quartz bracket, the positioning is accurate and reliable, the processing accuracy of the quartz bracket is guaranteed, and it is not easy to be damaged or broken during the processing; (2) During the clamping process of the bracket, the rotating column is tightened into the screw sleeve, so that the end face of the rod is pressed by the pressure column, ensuring that the support arm is reliably attached to the support surface. At the same time, the push rod is pushed and moved so that the ends of several adjusting rods are simultaneously pushed against the outer wall of the rod, accurately positioning the rod and ensuring the accuracy of the axial position of the rod.

[0030] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0031] Example 1: A quartz support processing fixture (see attached) Figure 1 To be continued Figure 3 The system includes a reference ring 1 and a fixing plate 2. The reference ring has a ring-shaped columnar structure. The fixing plate is installed on the reference ring, and its width is smaller than the diameter of the reference ring. A positioning groove 3 is provided on the lower surface of the fixing plate. The side walls at both ends of the positioning groove are arc-shaped. The upper end of the reference ring is adapted to connect with the positioning groove, and the side wall of the positioning groove is adapted to fit the outer wall of the reference ring. Fastening screws are connected between the fixing plate and the reference ring. The fixing plate is connected to a positioning seat 4. The quartz support includes a rod 5 and several support arms 6 connected to the rod. In this embodiment, three support arms are arranged circumferentially at intervals. The three support arms are connected to the rod in a Y-shaped structure, and the positioning seat is also Y-shaped. The positioning seat and the support arm are respectively provided with a support surface 7. The support arm abuts against the support surface. The positioning seat is provided with a circumferential fixed column 8 and a circumferential movable block 9. The circumferential fixed column and the circumferential movable block abut against both sides of the support arm to position the support arm circumferentially. The positioning seat and the circumferential movable block are respectively provided with a fixed block 10. The fixed block is provided with an adjusting screw that connects to the circumferential movable block. The adjusting screw rotates to adjust the distance between the fixed block and the circumferential movable block. The adjusting screw is threaded to the fixed block, and the end of the adjusting screw is rotatably connected to the circumferential movable block. A guide rod is connected to the circumferential movable block, and a guide hole 11 is provided on the fixed block. The guide rod is fitted into the guide hole. The circumferential fixed column is provided on one of the support surfaces, and three circumferential fixed columns are provided on this support surface. The three circumferential fixed columns are arranged radially at intervals. A circumferential movable block is installed on each support surface. The positioning seat and each support arm are respectively provided with several clearance grooves 12. The clearance grooves correspond to the positions on the support arm where countersunk holes need to be machined, leaving space for the machining of countersunk holes and avoiding interference.

[0032] A positioning groove 13 is provided on the fixed plate, and the rod body is adapted to connect with the positioning groove. A pressure plate 14 is connected to the fixed plate, and the pressure plate presses firmly onto the rod body. Bosses 15 are provided at both ends of the fixed plate, and the positioning groove is located on the two bosses. The bosses at both ends of the fixed plate leave a gap in the middle section, reducing errors caused by contact with the rod body and also reducing the weight of the fixed plate. A V-shaped pressure groove 16 is provided on the lower surface of the pressure plate, and the V-shaped pressure groove abuts against the rod body. A through hole 17 is provided on the positioning seat, through which the rod body passes. A slot 18 is provided on the positioning seat corresponding to the fixed plate, and the end of the fixed plate is adapted to be inserted into the slot. The fixed plate and the positioning seat are fastened together with screws. All screws in this patent are made of stainless steel, which will not rust or contaminate the product when immersed in water-based or oil-based cutting fluids. The reference ring, fixed plate, positioning seat, pressure plate, circumferential fixed column, circumferential movable block, and fixed block are all made of quartz.

[0033] The quartz holder is mounted on the fixture. Positioning grooves on the fixing plate support and position the rod of the quartz holder, while a pressure plate clamps the rod. The support arm of the quartz holder rests against the support surface on the positioning seat, providing a large support area and stable, reliable support, thus preventing vibration during product processing. The fixing plate is mounted on a reference ring, which is then installed on the processing equipment for easy centering, reducing manual calibration time.

[0034] Example 2: A quartz support processing fixture (see attached) Figure 4 Appendix Figure 5 Its structure is similar to that of Embodiment 1, the main difference being that in this embodiment, a threaded sleeve 19 is provided around the through hole on the positioning seat, and several clearance notches 20 are provided on the threaded sleeve and corresponding to the support arm. Three clearance notches are provided on the support arm and the support arm are provided. The support arm passes radially through the clearance notches. A sliding sleeve 21 is installed in the through hole, and several push rods 22 are evenly distributed on the sliding sleeve. The push rods extend into the threaded sleeve. A return spring 23 is installed between the sliding sleeve and the positioning seat. Several adjusting rods 24 are evenly distributed and hinged on the inner wall of the through hole. One end of the adjusting rod is located close to the outer wall of the rod body. A long groove 25 is provided on the adjusting rod. A connecting post 26 is provided on the push rod. The connecting post is connected to the long groove. A rotating post 27 is threadedly connected to the threaded sleeve. A pressure post 28 is connected to the rotating post. A buffer spring 29 is installed between the pressure post and the rotating post. The end of the rotating post abuts against the push rod, and the end of the pressure post abuts against the end face of the rod body. A mounting hole 30 is provided inside the rotating column. The buffer spring and one end of the pressure column are both installed in the mounting hole. A protruding ring 31 is provided on the outer wall of the pressure column. A limiting ring 32 is connected to the inner end of the rotating column. The limiting ring is used to limit the end face of the protruding ring and prevent the pressure column from dislodging from the mounting hole. Other structures are the same as in Embodiment 1.

[0035] After the quartz holder's rod passes through the through hole, it is supported in the positioning groove. Then, the rotating column is installed into the threaded sleeve. As the rotating column rotates, the end of the pressure column presses against the end face of the rod, thereby adjusting the axial position of the rod and ensuring that the support arm reliably fits against the support surface. Simultaneously, the rotating column presses against the top rod, and the top rod moves, driving the adjusting rod to rotate. This causes the ends of several evenly distributed adjusting rods to simultaneously press against the outer wall of the rod, precisely positioning the rod and ensuring the accuracy of its axial position. Finally, the pressure plate and circumferential movable block are connected to achieve reliable clamping of the quartz holder. This structural design makes the clamping of the quartz holder by the fixture more precise and reliable.

[0036] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Other variations and modifications may be made without departing from the technical solutions described in the claims.
