Description

Technical Field

[0001] The present invention relates to the technical field of positioning devices, and in particular to a positioning fixture. Background Art

[0002] A resonator is an electronic device that generates a resonant frequency. Commonly used ones include quartz crystal resonators and ceramic resonators. They are stable and have good anti-interference performance. They are widely used in various electronic products. The resonator mainly includes a main body and a first leg and a second leg electrically connected to the main body. During production, a positioning fixture is usually used to clamp and fix the resonator.

[0003] A traditional positioning fixture includes a carrier bar, which is provided with a first clamping groove and a second clamping groove. The first clamping groove and the second clamping groove are both provided with elastic pressure members. The first support leg and the second support leg are respectively inserted into the first clamping groove and the second clamping groove, and the elastic pressure member is used to clamp the first support leg and the second support leg to achieve clamping and fixing of the resonator.

[0004] However, the traditional positioning fixture has the following problems: First, due to the unreasonable structural setting of the elastic pressure piece and the stiff elastic force, the first leg and the second leg are easily bent and deformed when inserted; second, because the carrier strip is made of plastic material, the first leg and the second leg are easily plugged and pulled out for a long time, which easily causes serious wear of the inner walls of the first clamping groove and the second clamping groove, resulting in poor durability of the positioning fixture, and also increases the resistance when the first leg and the second leg are inserted, causing insertion obstruction and easy bending and deformation; third, the depth to which the first leg and the second leg can be freely inserted is only 1 / 6 of their total length, and the remaining 5 / 6 of the length needs to overcome the clamping force to be inserted into the first clamping groove and the second clamping groove. Such a structure also easily causes the first leg and the second leg to bend and deform. Summary of the Invention

When the first support leg and the second support leg are inserted, the lower ends of the first support leg and the second support leg respectively press the spring sheet, so that the spring sheet is elastically deformed outward with the supporting portion as a fulcrum. The spring sheet has a longer elastic deformation range and a softer elastic force, so that the first support leg and the second support leg can smoothly pass through the abutting portion downward and then be inserted into the first clamping space and the second clamping space, thereby preventing the first support leg and the second support leg from bending and deforming; at the same time, the spring sheet will not be fatigued and deformed after long-term use, and has a strong elastic retention ability and good reliability.

[0048] A third accommodating groove 25 is connected between the first accommodating groove 21 and the second accommodating groove 22, and the partition 40 can be removably installed in the third accommodating groove 25. The carrier bar 10 is provided with a mounting opening 251 connected to the third accommodating groove 25, and the partition 40 is inserted into or removed from the third accommodating groove 25 from the mounting opening 251. Specifically, the mounting opening 251 is provided on the upper surface of the clamp seat 11, and the partition 40 can be inserted into or removed from the third accommodating groove 25 in the up and down directions through the mounting opening 251; by providing the third accommodating groove 25 and the partition 40 being removably installed in the third accommodating groove 25, the partition 40 can be replaced regularly according to the use time or number of times of the positioning fixture, thereby avoiding excessive wear of the partition 40, which causes an increase in resistance to the first leg 52 or the second leg 53 during insertion, making the insertion of the first leg 52 and the second leg 53 smooth, and preventing the first leg 52 and the second leg 53 from bending, deforming or even being scrapped.

[0050] There are multiple positioning grooves 20, and the multiple positioning grooves 20 are arranged in the front-to-back direction. The third accommodating groove 25 extends in the front-to-back direction, and one side of the third accommodating groove 25 is connected with the multiple first accommodating grooves 21, and the other side of the third accommodating groove 25 is connected with the multiple second accommodating grooves 22. The partition 40 is arranged in a flat long strip shape; by setting the third accommodating groove 25 to be connected with the multiple first accommodating grooves 21 and the multiple second accommodating grooves 22, and the partition 40 is arranged in a long strip shape, an entire partition 40 can be inserted into or removed from the third accommodating groove 25 at one time, and the assembly and disassembly efficiency is high.

[0051] Specifically, a first glass surface 41 that can abut against the side wall surface of the first support leg 52 is formed on the side of the partition 40 facing the first clamping space 23, and a second glass surface 42 that can abut against the side wall surface of the second support leg 53 is formed on the side of the partition 40 facing the second clamping space 24. The first glass surface 41 and the second glass surface 42 are arranged in parallel, and the first glass surface 41 and the second glass surface 42 are both vertical planes. Specifically, the partition 40 is a crystal glass partition 40, the first glass surface 41 is a first crystal glass surface, and the second glass surface 42 is a second crystal glass surface. By respectively arranging the first glass surface 41 and the second glass surface 42 on both sides of the partition 40, since the friction coefficient of the first glass surface 41 and the second glass surface 42 is extremely low and has the excellent characteristic of being highly smooth, when the first support leg 52 and the second support leg 53 are respectively inserted into the first clamping space 23 and the second clamping space 24, the first support leg 52 moves along the first glass surface 41 to Sliding down, the second leg 53 slides downward along the second glass surface 42, thereby effectively reducing the wear between the first leg 52 and the partition 40, as well as reducing the wear between the second leg 53 and the partition 40, extending the service life of the partition 40, and increasing the durability of the positioning fixture. The first leg 52 and the second leg 53 slide down more smoothly, preventing the first leg 52 from bending and deforming, reducing the loss of the product 50, and using a partition 40 made of crystal glass has a better effect; by adopting a first glass surface 41 and a second glass surface 42 that are arranged in parallel, and the first glass surface 41 and the second glass surface 42 are both vertical planes, so that the first leg 52 and the second leg 53 are respectively attached to the first glass surface 41 and the second glass surface 42, the straightness of the first leg 52 and the second leg 53 in the up and down directions can be maintained, thereby avoiding the bending and deformation of the first leg 52 and the second leg 53, and the use of the first glass surface 41 and the second glass surface 42 makes the partition 40 durable and electrically insulating.

[0052] It should be noted that the partition 40 of the present invention can be entirely formed of crystal glass; or a structure in which a first crystal glass plate and a second crystal glass plate are respectively provided on both sides of the partition 40, and the partition 40 can be made of materials other than glass.

[0053] The upper end of the spring piece 31 is bent downward to form a support plate 34, and the support portion 32 is provided at the connection between the support plate 34 and the spring piece 31. The side of the support plate 34 away from the partition 40 abuts against the inner wall of the first accommodating groove 21: by providing a downward-bent support plate 34 at the upper end of the spring piece 31, the side of the support plate 34 away from the partition 40 abuts against the inner wall of the first accommodating groove 21 to provide a stable supporting effect, so that the spring piece 31 is elastically deformed and stretched out in the process of elastic deformation, and the elastic force is soft.

[0054] A guiding slope 311 is formed on the side of the spring piece 31 facing the partition 40, and the lower end of the guiding slope 311 extends to the abutment portion 33. Specifically, the angle θ between the guiding slope 311 and the partition 40 is 8°~20°, and preferably θ is 13°; by setting the guiding slope 311, when the first leg 52 is inserted, the guiding effect of the guiding slope 311 is utilized to make the lower end of the first leg 52 slide smoothly to the abutment portion 33, and be inserted into the first clamping space 23 for clamping, and the positioning and clamping efficiency is high.

[0055] The height h1 of the spring piece 31 is greater than or equal to 1 / 2 of the vertical distance h2 between the abutting portion 33 and the positioning groove 20. Specifically, the height h1 of the spring piece 31 is greater than or equal to 2 / 3 of the vertical distance h2 between the abutting portion 33 and the positioning groove 20. By setting the height h1 of the spring piece 31 to be greater than or equal to 1 / 2 of the vertical distance h2 between the abutting portion 33 and the positioning groove 20, the position of the abutting portion 33 relative to the positioning groove 20 is lowered, the elastic deformation range of the spring piece 31 is longer, the elastic force is softer, and the first leg 52 and the second leg 53 are respectively inserted into the first clamping space 23 and the second clamping space 24 to a greater depth before contacting the abutting portion 33, thereby preventing the first leg 52 and the second leg 53 from bending and deforming during the insertion process, thereby protecting the first leg 52 and the second leg 53. 3, and the product 50 can be inserted into the positioning fixture without the assistance of a transfer fixture; if the height h1 of the spring piece 31 is ≥ 2 / 3 of the vertical distance h2 between the abutting portion 33 and the positioning groove 20, it can not only meet a certain elastic force to clamp the first leg 52 and the second leg 53, but also make the first leg 52 and the second leg 53 more smoothly inserted and removed, and the effect is better; in actual application, the depth of the first leg 52 and the second leg 53 that can be freely inserted can exceed 5 / 6 of its own length, and only 1 / 6 of the length needs to overcome the clamping force of the spring piece 31 for insertion, plus the soft elastic force and the glass-surfaced partition make the positioning fixture not easily damaged, and will not form an insertion obstacle, and the first leg 52 and the second leg 53 are not easily deformed during insertion.

The support seat 35, the support plate 34 and the spring piece 31 are integrally formed, so that the elastic pressure member 30 can be manufactured by stamping, which is easy to produce and reduces costs. The elastic pressure member 30 can be installed in the first accommodating groove 21 at one time, and the installation efficiency is high.

[0057] Baffles 351 are provided on opposite sides of the lower end of the support seat 35, and the baffles 351 abut against the opening edge of the lower end of the first accommodating groove 21 to limit the upward movement of the support seat 35. Guide plates 352 are provided on opposite sides of the upper end of the support seat 35, and the guide plates 352 extend inward from bottom to top. By providing the baffles 351, during assembly, the baffles 351 abut against the opening of the lower end of the first accommodating groove 21, so that the elastic pressing member 30 can be assembled into place, which is convenient for assembly. By providing the guide plates 352, the guiding effect can be utilized to facilitate the support seat 35 to be inserted into the first accommodating groove 21 from bottom to top, which is convenient for assembly.

[0058] The lower surface of the carrier bar 10 is recessed with a mounting groove 26, and the first accommodating groove 21 and the second accommodating groove 22 are both provided on the top wall surface of the mounting groove 26. Specifically, the mounting groove 26 is provided on the lower surface of the clamping seat 11; by providing the mounting groove 26, it is convenient for the elastic pressing member 30 to be inserted upward from the mounting groove 26 into the first accommodating groove 21 or the second accommodating groove 22, respectively, thereby improving assembly efficiency.

[0059] It should also be noted that the present invention is applicable to positioning and clamping electronic devices, such as quartz crystal resonators, and is also applicable to other products 50 having a main body 51, a first leg 52 and a second leg 53, and is not limited to electronic devices.

[0060] The method of using the present invention is as follows: first align the first leg 52 and the second leg 53 of the product 50 with the first clamping space 23 and the second clamping space 24, and then move the product 50 downward. After the first leg 52 and the second leg 53 move downward to a certain depth along the first glass surface 41 and the second glass surface 42 of the partition 40 respectively, the lower end of the first leg 52 and the lower end of the second leg 53 respectively press downward against the first elastic member and the second elastic member, so that the spring piece 31 elastically deforms outward and stretches open, and continue to move the product 50 downward so that the abutting portion 33 clamps the first leg 52 and the second leg 53, and the main body 51 is embedded in the positioning groove 20 to complete the positioning and clamping of the product 50. Finally, the detection unit or the welding unit is used to detect or weld the product 50.

[0061] To sum up, the present invention arranges a spring piece 31 on the elastic pressure piece 30, and the spring piece 31 extends obliquely from top to bottom toward the partition 40, and a support portion 32 is arranged at the upper end of the spring piece 31, and an abutment portion 33 is arranged at the lower end of the spring piece 31, and the abutment portion 33 is arranged below the support portion 32.
