Abstract
Description
Technical Field
[0001] This utility model relates to the field of crystal rod processing technology, specifically to a batch clamping fixture for crystal rods. Background Technology
[0002] In the precision machining of crystal materials, both ends of the crystal rod need to be ground sequentially to obtain flat and parallel end faces. Traditional grinding processes typically involve manual operation, grinding one end of each crystal rod one by one before flipping it over to grind the other end. This results in a long overall processing cycle, low production efficiency, and, due to its reliance on manual operation, is easily affected by the operator's experience and skill level, leading to deviations in the parallelism of the two end faces of the same crystal rod or inconsistent grinding quality between different crystal rods, thus affecting product yield and batch stability.
[0003] To improve processing efficiency, some clamping fixtures are designed with multiple holes to accommodate crystal rods, allowing them to hold multiple crystal rods simultaneously for batch grinding. However, each crystal rod in such fixtures typically needs to be individually fastened with a separate fastener, making the clamping process cumbersome and time-consuming, and hindering the achievement of fast and synchronous batch clamping.

[0019] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0020] A batch clamping fixture for crystal rods includes a support frame 1. The support frame 1 has a mounting plate 2 arranged along the left-right direction. The mounting plate 2 has multiple clamping slots 3 on both the front and rear sides, and the multiple clamping slots 3 are arranged at intervals along the length direction of the mounting plate 2. The mounting plate 2 also has multiple clamping mechanisms 4. The clamping mechanism 4 includes a first clamping plate 41 located on the front side of the mounting plate 2 and a second clamping plate 42 located on the rear side of the mounting plate 2. The first clamping plate 41 corresponds to at least two clamping slots 3 on the front side of the mounting plate 2, and the second clamping plate 42 corresponds to at least two clamping slots 3 on the rear side of the mounting plate 2. The clamping mechanism 4 also includes a linkage mechanism 43 that can drive the first clamping plate 41 and the second clamping plate 42 to move towards each other, thereby clamping and fixing the crystal rod in its corresponding clamping slot 3.
[0021] The support frame 1 stably supports the mounting plate 2 on the worktable of the grinding equipment. The mounting plate 2 is horizontally mounted on the support frame 1 and extends in the left-right direction. Multiple clamping slots 3 are provided on both the front and rear sides of the mounting plate 2. The clamping slots 3 can accommodate the crystal rod and abut against its outer circumferential surface. Figure 1 and Figure 2 As shown in the embodiment, multiple clamping positions 3 are arranged symmetrically on the front and rear sides of the mounting plate 2 along its length, and clamping mechanisms 4 are arranged side-by-side on the mounting plate 2 along its length. A first clamping plate 41 is located on the front side of the mounting plate 2, and a second clamping plate 42 is located on the rear side. Both the first clamping plate 41 and the second clamping plate 42 have inner surfaces corresponding to the clamping positions 3 and used to press against the outer surface of the crystal rod. The crystal rod is clamped by the cooperation of the pressing surfaces and the clamping positions 3. A linkage mechanism 43 drives the first clamping plate 41 and the second clamping plate 42 to move synchronously in opposite directions, thereby clamping and releasing the crystal rod.
[0022] In one embodiment, when using the fixture, the operator first places multiple crystal rods into the corresponding clamping slots 3 on the front and rear sides of the mounting plate 2. Then, by driving the linkage mechanism 43 in each clamping mechanism 4, the first clamping plate 41 and the second clamping plate 42 move inward synchronously until the inner surfaces of the first clamping plate 41 and the second clamping plate 42 are in contact with the outer surface of the crystal rod and a clamping force is applied. Since each first clamping plate 41 and the second clamping plate 42 corresponds to at least two clamping slots 3, each clamping mechanism 4 can fix the crystal rods on multiple clamping slots 3. Then, the fixture is sent to a grinding equipment, which performs batch grinding on the upper surface of all the crystal rods. After grinding is completed, the linkage mechanism 43 is driven in reverse to retract the two clamping plates, and all the crystal rods are taken out as a whole. The crystal rods are then flipped over, re-clamped and fixed according to the aforementioned method, and the fixture is sent back to the grinding equipment to grind the other end surface of the crystal rods.
[0023] The first clamping plate 41 and the second clamping plate 42 cover multiple clamping positions 3, and the linkage mechanism 43 drives the first clamping plate 41 and the second clamping plate 42 to move towards each other to clamp and fix the crystal rods in the multiple clamping positions 3, thereby improving the clamping efficiency.
[0024] The linkage mechanism 43 includes a slide rod 431. The first clamping plate 41 and the second clamping plate 42 are sleeved on the slide rod 431 and can slide along the axial direction of the slide rod 431. The front end of the slide rod 431 is provided with a pressing part 432, which is disposed opposite to the outer side of the first clamping plate 41. The rear part of the slide rod 431 is threaded with a linkage nut 433, which is disposed opposite to the outer side of the second clamping plate 42.
[0025] The pressing part 432 can be a stop block located at the front end of the slide rod 431, or it can be a head integrally formed with one end of the slide rod 431. The slide rod 431 is machined with an external thread section, and the linkage nut 433 has an internal thread that matches the external thread of the slide rod 431. In one embodiment, the slide rod 431 is specifically a screw rod, and the pressing part 432 is a nut fixedly installed at the front end of the screw rod. The first clamping plate 41 and the second clamping plate 42 are respectively provided with a first sliding hole 413 and a second sliding hole 423 for the slide rod 431 to pass through, so that the first clamping plate 41 and the second clamping plate 42 can slide along the axial direction of the slide rod 431. In the initial state, the pressing part 432 is located on the front side of the first clamping plate 41 and faces the front end face of the first clamping plate 41; the linkage nut 433 is located on the rear side of the second clamping plate 42 and faces the rear end face of the second clamping plate 42.
[0026] When the linkage nut 433 is rotated, it moves forward under the drive of the thread and presses against the rear end face of the second clamping plate 42, forcing the second clamping plate 42 to slide forward along the slide rod 431, thereby clamping the crystal rod in its corresponding rear clamping position 3. At this time, if the linkage nut 433 is tightened further, it will apply a reverse axial pulling force to the slide rod 431 through the threaded connection, forcing the slide rod 431 to move backward, and causing its front pressing part 432 to push the front end face of the first clamping plate 41 to drive the first clamping plate 41 to move backward, thereby clamping the crystal rod in the corresponding front clamping position 3 of the first clamping plate 41.
[0027] The first clamping plate 41 and the second clamping plate 42 are both elongated plates capable of covering two adjacent clamping positions 3. The first clamping plate 41 has a first clamping part 411 and a second clamping part 412 formed on its left and right sides, respectively, and the first clamping plate 41 has a first sliding hole 413 between the first clamping part 411 and the second clamping part 412. The second clamping plate 42 has a third clamping part 421 and a fourth clamping part 422 formed on its left and right sides, respectively, and the second clamping plate 42 has a second sliding hole 423 between the third clamping part 421 and the fourth clamping part 422. The sliding rod 431 is arranged to pass through the first sliding hole 413 and the second sliding hole 423 in sequence.
[0028] The first clamping plate 41 and the second clamping plate 42 are elongated plates, allowing a single clamping plate to cover two adjacent clamping positions 3, reducing the number of clamping elements, enabling batch clamping, and improving clamping efficiency. In one embodiment, the first sliding hole 413 and the second sliding hole 423 on the clamping plate are both machined as smooth holes. When the slide rod 431 of the linkage mechanism 43 passes through, it ensures that a sliding pair relationship is formed between the clamping plate and the slide rod 431, allowing the clamping plate to be smoothly pushed and slid. The two clamping parts are respectively located on the left and right sides of the clamping plate, and the sliding hole is located in the middle of the two clamping parts, so that when the linkage nut 433 is tightened, the driving force can be evenly distributed to the left and right clamping parts, which helps to maintain the balance of clamping force.
[0029] The clamping position 3 is a V-shaped groove opened on the side wall of the mounting plate 2 and extending in the vertical direction. The two positioning inclined surfaces of the V-shaped groove form two lines of contact with the outer circular surface of the crystal rod. When the first clamping plate 41 and the second clamping plate 42 move from the outside towards the mounting plate 2, they can press the crystal rod into the V-shaped groove, thereby completing the clamping of the crystal rod.
[0030] like Figure 1 and Figure 2 As shown in the embodiment, the clamping position 3 is a right-angled V-shaped groove, and the bottom of the V-shaped groove is provided with a relief groove extending in the vertical direction, which facilitates processing.
[0031] The thickness of the first clamping plate 41 and / or the second clamping plate 42 gradually decreases from the middle to the left and right ends, thereby concentrating the mass of the clamping plate in the middle, reducing the lever arm length, and improving the attitude stability of the clamping plate during the sliding process along the slide bar 431.
[0032] The mounting plate 2 has multiple through mounting holes 21 along its width direction. The slide rod 431 passes through the mounting holes 21 and can slide along the axial direction of the mounting holes 21. In this embodiment, the mounting holes 21 are machined as smooth holes, providing a stable guide path for the slide rod 431 and ensuring linearity of movement.
[0033] The mounting plate 2 is provided with a weight reduction hole 22 in the vertical direction, which is connected to the mounting hole 21. The weight reduction hole 22 is used to reduce the contact area between the wall of the mounting hole 21 and the slide rod 431.
[0034] The mounting plate 2, as the core load-bearing component of the entire clamping fixture, needs to simultaneously support multiple crystal rods, clamping plates, and the linkage mechanism 43, and withstand vibration and clamping forces during the grinding process. Therefore, it must possess sufficient structural strength and rigidity. To meet the strength requirements, the mounting plate 2 needs to be machined from a single piece of thick metal sheet, resulting in a large overall weight. This significant weight affects the operator's ease of clamping. The weight-reducing holes 22 allow material to be removed from areas that do not affect the main load-bearing path, effectively reducing the total weight of the mounting plate 2. Figure 3 and Figure 4 As shown in the embodiment, the weight reduction hole 22 is connected to the mounting hole 21 to reduce the actual contact area between the sliding pairs, thereby reducing wear and improving the smoothness and flexibility of the slide rod 431 sliding along the axial direction of the mounting hole 21.
[0035] The top surface of the mounting plate 2 is flat, and the operator can place the top surface of the mounting plate 2 as a base on a horizontal workbench to install the crystal rod, thereby improving the ease of crystal rod installation.
[0036] Two support frames 1 are respectively arranged on the left and right sides of the mounting plate 2, and each support frame 1 is provided with a detachable connection structure 5 between itself and the mounting plate 2. In this embodiment, the detachable connection structure 5 includes a first insertion hole on the support frame 1, a second insertion hole corresponding to the first insertion hole on the mounting plate 2, and a pin passing through the first and second insertion holes between the support frame 1 and the mounting plate 2. The detachable connection structure 5 facilitates maintenance of the mounting plate 2.
