Description

Technical Field

[0001] This invention belongs to the field of clamping fixture technology, and particularly relates to a quartz bracket clamping fixture and its usage method. Background Technology

[0002] Fixtures, also known as jigs, are indispensable tools in industrial manufacturing. Their main function is to fix and stabilize workpieces to ensure precise machining and assembly.

[0003] Quartz supports are devices used to hold and support quartz products or related materials, and are widely used in photovoltaics, semiconductors, laboratories, and many other fields. A typical quartz support structure is as follows: Figure 1 As shown, it includes a main body and a support. The main body has a tubular structure, and the support consists of multiple support feet spaced circumferentially at one end of the main body. When existing clamps hold quartz holders, they often fix one side or a certain point of the quartz holder. This will cause uneven stress on the quartz holder and may easily lead to the breakage of multiple support feet. Therefore, it is necessary to improve the existing quartz holder clamps. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a quartz holder clamping fixture and its usage method. This clamping fixture provides a relatively uniform clamping force on the quartz holder when clamping it, and can accurately clamp quartz holders of different specifications. The clamping process is simple to operate and the structure is stable.

[0005] In view of this, the present invention provides a quartz holder clamping fixture, comprising:

[0006] The support ring has multiple support grooves at its end for positioning the support feet on the quartz bracket.

[0007] Multiple radial clamping blocks are spaced circumferentially on the inner side of the support ring. The radial clamping blocks can move radially along the support ring. The proximal ends of the multiple radial clamping blocks cooperate to clamp the main body of the quartz bracket.

[0008] A radial drive mechanism is used to adjust the position of these radial clamping blocks in the radial direction of the support ring;

[0009] The positioning seat is located at the end of the support ring away from the support groove. The positioning seat can pre-position the main body of the quartz holder.

[0010] In this technical solution, the end of the quartz holder furthest from the support foot is placed on the positioning seat, and then the support foot of the quartz holder is inserted into multiple support grooves on the support ring to position one end of the support foot of the quartz holder. Then, the radial drive mechanism drives multiple radial clamping blocks to approach the quartz holder radially along the support ring, so that the multiple radial clamping blocks cooperate to clamp the main body of the quartz holder. After clamping, the main body of the quartz holder is coaxially distributed with the support ring. In this way, the contact points of each support foot and the corresponding support groove coincide in the circumferential direction, so that the quartz holder is subjected to uniform force.

[0011] Furthermore, the above technical solution also includes a base, a support ring and a positioning seat, all of which are located on the base. The support ring can be height-adjusted on the base, and the positioning seat can be horizontally adjusted on the base.

[0012] In the above technical solution, a height adjustment mechanism is further provided between the support ring and the base, the height adjustment mechanism including:

[0013] Multiple sets of telescopic rods are arranged in an array, with each end of the telescopic rod connected to a support ring and a base, respectively.

[0014] The upper end of the fixing rod is connected to the support ring, and the lower end of the fixing rod has threads on its outer wall.

[0015] The rotating sleeve has its lower end rotatably connected to the base, and its upper surface has a threaded hole. The lower end of the fixing rod is threadedly connected to the rotating sleeve.

[0016] In the above technical solution, a fixed seat is provided on the base and on one side of the support ring. The fixed seat is provided with a limiting slide rail. A limiting slide groove is provided at the bottom of the positioning seat. The positioning seat is slidably connected to the limiting slide rail through the limiting slide groove.

[0017] In the above technical solution, the positioning seat is further provided with a locking screw hole that connects to the limiting slide groove, and the positioning seat is provided with a locking screw. The threaded end of the locking screw is threadedly connected to the locking screw hole and extends into the limiting slide groove.

[0018] In the above technical solution, the radial drive mechanism further includes:

[0019] Multiple drive slots are spaced apart circumferentially on the outer wall of the support ring, and the drive slots penetrate the inner wall of the support ring. The distal end of the radial clamping block extends into the drive slot.

[0020] Multiple guide frames are spaced circumferentially on the inner wall of the support ring, and the radial clamping block is slidably connected to the guide frames;

[0021] The elastic element has two ends connected to the guide frame and the radial clamping block, respectively.

[0022] A driving arc is provided in each driving slot. The proximal side of the driving arc is inclined in the circumferential direction and contacts the distal end of the radial clamping block.

[0023] The drive ring is rotatably sleeved outside the support ring, and the inner wall of the drive ring is connected to the distal side of the drive arc.

[0024] In the above technical solution, the upper surface of the positioning seat is V-shaped.

[0025] In the above technical solution, the proximal end surface of the radial clamping block is further arc-shaped.

[0026] This invention also discloses a method for using the aforementioned quartz holder clamping fixture, comprising the following steps:

[0027] Step 1: After passing the main body of the quartz holder through the support ring, place it on the positioning seat and insert the multiple support feet of the quartz holder into the multiple support slots;

[0028] Step 2: Adjust the height of the support ring to make the main body of the quartz holder horizontal;

[0029] Step 3: The rotating drive ring moves in an arc around the support ring in the corresponding drive groove, causing the drive arc to push the radial clamping blocks toward the center. Multiple radial clamping blocks simultaneously approach the quartz holder and clamp the main body of the quartz holder.

[0030] The beneficial effects of this invention are:

[0031] 1. By setting multiple support grooves and multiple radial clamping blocks at intervals in the circumferential direction of the support ring, the main body of the quartz holder and multiple support feet can be clamped with uniform force in the circumferential direction, which improves the uniformity of force when the quartz holder is clamped and makes the quartz holder less prone to local breakage. In addition, the positioning seat can be set to pre-position the quartz holder before clamping, which facilitates the clamping of the quartz holder.

[0032] 2. By designing the support ring with an adjustable height relative to the base, even if the quartz holder is not kept horizontal after pre-positioning, simply adjusting the height of the support ring will bring the quartz holder to a horizontal position, which is beneficial for coaxial clamping of the quartz holder and the support ring. By designing the positioning seat with an adjustable horizontal position, when clamping quartz holders of different lengths, the horizontal position of the positioning seat can be adjusted as needed to accommodate quartz holders of different lengths.

[0033] 3. The height between the support ring and the base is adjusted by the cooperation of multiple sets of telescopic rods, fixed rods, and rotating sleeves. Simply apply force to rotate the rotating sleeve to move the support ring vertically relative to the base, thereby adjusting the height of the support ring. The operation is simple.

[0034] 4. The horizontal position of the positioning seat is moved by the cooperation of the limiting slide rail and the limiting slide groove, which ensures the flexibility of the positioning seat movement. Then, the positioning seat is locked and unlocked by the cooperation of the locking screw hole and the locking screw, which ensures the stability of the positioning seat during use.

[0035] 5. By cooperating with multiple drive slots, multiple guide frames, elastic elements, drive arcs, and drive rings, the radial position of multiple radial clamping blocks can be adjusted simultaneously. The movement of the radial clamping blocks can be achieved simply by rotating the drive ring at a certain angle. The operation is simple and the drive efficiency is high. Attached Figure Description

[0051] Quartz support

[0052] The quartz support in this invention is as follows Figure 1 As shown, the quartz holder has a cylindrical main body 100 and a plurality of support feet 200 disposed at the ends of the main body 100, the plurality of support feet 200 being distributed at intervals along the circumference of the main body 100.

[0053] Example 1

[0054] like Figures 2-4 As shown in the figure, this application provides a quartz holder clamping fixture, including: a base 5, a support ring 1, multiple radial clamping blocks 2, a radial drive mechanism 3, and a positioning seat 4.

[0055] Please see Figure 2 The end of the support ring 1 is provided with a plurality of support grooves 101 for the support feet 200 on the positioning quartz bracket. The number of support grooves 101 can be the same as the number of support feet 200, or it can be a multiple of the number of support feet 200. Each support foot 200 can be inserted into a support groove 101.

[0056] Please see Figure 4 Multiple radial clamping blocks 2 are circumferentially spaced on the inner side of the support ring 1. The radial clamping blocks 2 can move radially along the support ring 1. The proximal ends of the multiple radial clamping blocks 2 cooperate to clamp the main body 100 on the quartz bracket. In this embodiment, the proximal end surface of the radial clamping blocks 2 is arc-shaped. The radial drive mechanism 3 is used to adjust the position of these radial clamping blocks 2 in the radial direction of the support ring 1. In the prior art, any structure that can adjust the position of these radial clamping blocks 2 in the radial direction of the support ring 1 can be used as the radial drive mechanism 3 in this embodiment.

[0057] Please see Figure 3 The positioning seat 4 is located at the end of the support ring 1 away from the support groove 101. The positioning seat 4 can pre-position the main body 100 on the quartz bracket. In this embodiment, the upper surface of the positioning seat 4 is V-shaped, which facilitates the support of the outer circumference of the main body 100 of the quartz bracket.

[0058] Both the support ring 1 and the positioning seat 4 are located on the base 5, which is used to support the support ring 1 and the base 5.

[0059] It should be noted that in this embodiment, the proximal end refers to the end closer to the axis of the support ring 1, and the distal end refers to the end farther away from the axis of the support ring 1.

[0060] In this embodiment, the end of the quartz bracket away from the support foot 200 is placed on the positioning seat 4, and then the support foot 200 of the quartz bracket is inserted into multiple support grooves 101 on the support ring 1 to position one end of the support foot 200 of the quartz bracket. Then, the radial drive mechanism 3 drives multiple radial clamping blocks 2 to approach the quartz bracket radially along the support ring 1, so that the multiple radial clamping blocks 2 cooperate to clamp the main body 100 of the quartz bracket. After clamping, the main body 100 of the quartz bracket is coaxially distributed with the support ring 1. In this way, the contact points of each support foot 200 and the corresponding support groove 101 coincide in the circumferential direction, so that the quartz bracket is subjected to uniform force.

[0061] Example 2

[0062] This embodiment provides a quartz bracket clamping fixture. The difference from Embodiment 1 is that in this embodiment, both the support base and the positioning base 4 are adjustable on the base 5.

[0063] In this embodiment, both the support ring 1 and the positioning seat 4 are mounted on the base 5. The support ring 1 can be height-adjusted on the base 5, and the positioning seat 4 can be horizontally adjusted on the base 5.

[0064] Specifically, a height adjustment mechanism 6 is provided between the support ring 1 and the base 5. The height adjustment mechanism 6 includes: multiple sets of telescopic rods 601, a fixed rod 602, and a rotating sleeve 603.

[0065] Please see Figure 2 Multiple sets of telescopic rods 601 are arranged in an array. The rectangular array distribution means that multiple sets of telescopic rods 601 are arranged in a rectangular, rhomboid, or other array below the support ring 1. The two ends of the telescopic rods 601 are connected to the support ring 1 and the base 5, respectively. The telescopic rods 601 can be extended and shortened. The multiple sets of telescopic rods 601 play a guiding and limiting role in adjusting the height of the support ring 1.

[0066] Please see Figure 4 The upper end of the fixing rod 602 is connected to the support ring 1, and the lower end of the fixing rod 602 is threaded on the outer wall; the lower end of the rotating sleeve 603 is rotatably connected to the base 5, and the upper surface of the rotating sleeve 603 is threaded with a threaded hole 6031, and the lower end of the fixing rod 602 is threadedly connected to the rotating sleeve 603.

[0067] In this embodiment, when it is necessary to adjust the height of the support ring 1, the operator can rotate the rotating sleeve 603 to drive the fixed rod 602 to move vertically through the threaded transmission, thereby adjusting the height of the support ring 1. Some quartz holders do not maintain a horizontal state after pre-positioning. If the quartz holder is clamped in this way, the contact points between the clamped quartz holder and the clamp may be unevenly stressed, affecting the structural stability of the quartz holder. In this embodiment, at this time, it is only necessary to adjust the height of the support ring 1 to adjust the quartz holder to a horizontal state, which is conducive to the coaxial clamping of the quartz holder and the support ring 1.

[0068] Please see Figure 3 A fixed seat 7 is provided on the base 5 and located on one side of the support ring 1. The fixed seat 7 is connected to the base 5 by fasteners. A limiting slide rail 701 is provided on the fixed seat 7. The longitudinal section of the limiting slide rail 701 is a trapezoid with a wider top and a narrower bottom. A limiting slide groove 401 is provided at the bottom of the positioning seat 4. The longitudinal section of the limiting slide groove 401 is also a trapezoid with a wider top and a narrower bottom. The positioning seat 4 is slidably connected to the limiting slide rail 701 through the limiting slide groove 401. A locking screw hole 402 is provided on the positioning seat 4 and communicates with the limiting slide groove 401. A locking screw 8 is provided on the positioning seat 4. The threaded end of the locking screw 8 is threadedly connected to the locking screw hole 402 and extends into the limiting slide groove 401.

[0069] In this embodiment, when it is necessary to adjust the horizontal position of the positioning seat 4, the operator loosens the locking screw 8 so that the threaded end of the locking screw 8 is away from the limiting slide rail 701. At this time, the positioning seat 4 can slide flexibly horizontally on the limiting slide rail 701. When it is necessary to lock the positioning seat 4 in the current position, the operator tightens the locking screw 8 so that the threaded end of the locking screw 8 is tightly abutted against the surface of the limiting slide rail 701. This restricts the horizontal sliding of the positioning seat 4 on the limiting slide rail 701. This ensures both the flexibility of the positioning seat 4 in movement and the stability of the positioning seat 4 during use.

[0070] Example 3

[0071] like Figures 5-8 As shown, this embodiment provides a quartz bracket clamping fixture, and based on embodiment 2, it also discloses a structure of the radial drive mechanism 3;

[0072] The radial drive mechanism 3 includes: multiple drive slots 301, multiple guide frames 302, an elastic element 303, a drive arc 304, and a drive ring 305.

[0073] Please see Figure 8Multiple drive slots 301 are circumferentially spaced on the outer wall of the support ring 1, and the drive slots 301 penetrate the inner wall of the support ring 1. The distal end of the radial clamping block 2 extends into the drive slot 301. Multiple guide frames 302 are circumferentially spaced on the inner wall of the support ring 1. The radial clamping block 2 is slidably connected to the guide frame 302. The figure shows three drive slots 301 as an example. At this time, there are also three radial clamping blocks 2 and three guide frames 302.

[0074] Please see Figure 6 The two ends of the elastic element 303 are connected to the guide frame 302 and the radial clamping block 2 respectively. When these radial clamping blocks 2 are far apart from each other, the elastic element 303 is slightly compressed. At this time, the elastic element 303 has elastic force. When these radial clamping blocks 2 clamp the main body 100 of the quartz holder, the elastic element 303 is in a more compressed state. At this time, the elastic element 303 has greater elastic force.

[0075] Please see Figure 7 Each drive groove 301 is provided with a drive arc 304. The proximal side of the drive arc 304 is inclined in the circumferential direction. The proximal side of the drive arc 304 contacts the distal end of the radial clamping block 2. As the contact point between the radial clamping block 2 and the drive arc 304 moves from the proximal position to the distal position, the elastic element 303 gradually relaxes and the elastic force causes the radial clamping block 2 to move in the distal direction. As the contact point between the radial clamping block 2 and the drive arc 304 moves from the distal position to the proximal position, the radial clamping block 2 moves in the proximal direction, and the elastic element 303 is squeezed to a greater extent. The drive ring 305 is rotatably sleeved on the outside of the support ring 1, and the inner wall of the drive ring 305 is connected to the distal side of the drive arc 304.

[0076] In this embodiment, before placing the quartz holder, the drive ring 305 is rotated to drive the three drive arcs 304 to make arc movements in the corresponding drive grooves 301, so that the three radial clamping blocks 2 move away from each other, leaving enough space in the middle of the inner side of the support ring 1. After the quartz holder is placed and pre-positioned, the drive ring 305 is rotated again to drive the three drive arcs 304 to make arc movements in the corresponding drive grooves 301, so that the three radial clamping blocks 2 move closer to each other, and finally clamp the main body 100 of the quartz holder.

[0077] Example 4

[0078] This embodiment discloses a method for using a quartz bracket clamping fixture, which is applicable to the quartz bracket clamping fixture in Embodiment 3.

[0079] In this embodiment, the method of using the quartz support clamping fixture includes the following steps:

[0080] Step 1: After passing the main body 100 of the quartz holder through the support ring 1, place it on the positioning seat 4, and insert the multiple support feet 200 of the quartz holder into the multiple support slots 101;

[0081] Step 2: Adjust the height of the support ring 1 so that the main body 100 of the quartz holder is horizontal;

[0082] Step 3: The rotating drive ring 305, along with the drive arc 304, moves in an arc around the support ring 1 in the corresponding drive groove 301, causing the drive arc 304 to push the radial clamping block 2 toward the center. Multiple radial clamping blocks 2 simultaneously approach the quartz bracket and clamp the main body 100 of the quartz bracket.

[0083] In this embodiment, in step one, before placing the quartz holder, the drive ring 305 is rotated to make the multiple radial clamping blocks 2 move away from each other by a certain distance, so that the main body 100 of the quartz holder can easily pass through the inner center of the support ring 1; in step two, the judgment of adjusting the quartz holder to a horizontal state can be made by visual inspection or by using measuring tools for observation.

[0084] By using the quartz bracket clamping fixture of this embodiment, the main body 100 of the quartz bracket can be coaxially clamped with the support ring 1 when clamping the quartz bracket. The clamping force of the multiple radial clamping blocks 2 on the main body 100 of the quartz bracket is directed towards the axis of the main body 100 of the quartz bracket. The multiple support feet 200 of the quartz bracket can also be supported at intervals along the circumference of the support ring 1. The contact points of each support foot 200 and the corresponding support groove 101 coincide in the circumferential direction. In this way, the force is evenly distributed at each clamping position when the quartz bracket is clamped, and it is not easy to break locally.

[0085] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
