Description

Technical Field

[0001] The utility model relates to the technical field of sensor processing, in particular to a clamp for processing a cylindrical shear beam sensor. Background Art

[0002] A beam sensor is actually a device that converts a mass signal into a measurable electrical output. Beam load cells operate as simple shear beams that bend slightly when subjected to force or weight. They are usually fixed at one end and free at the other, behaving much like a diving board, although there are also double-ended designs that are mounted at both ends and mounted in the center, more like a hammock. In addition, beam load cells can usually be seen divided into two subcategories, depending on how they measure force or weight. Bending beam cells measure the amount of shear deformation, while shear beam load cells measure the amount of bending distortion. When processing beam sensors, a fixture is required to clamp the beam sensor.

In view of the problem that it is not convenient to tightly fix the sensor and the sensor probe during the welding process of the existing weighing sensor, which leads to reduced quality and efficiency of the welding process, the following scheme is proposed, which includes a base, a rotating groove is provided on the top of the base, a fixed seat is rotatably installed in the rotating groove, a placement groove is provided on the top of the fixed seat, a vertical rod is fixedly installed on the top of the fixed seat by welding, a first slide groove is provided on one side of the vertical rod, a positioning mechanism is provided in the first slide groove, and two symmetrical second slide grooves are provided on the bottom inner wall of the placement groove. The utility model can facilitate the tight fixation of the sensor and the sensor probe during the welding process of the weighing sensor, thereby improving the quality and efficiency of the welding process, and has a simple structure and is easy to use.

[0004] The existing technology has the following problems:

In addition, when the cylindrical shear beam sensor processing fixture is used for a long time, the clamping components cannot be replaced according to the needs, which makes it inconvenient to promote and use. At the same time, it cannot play a good protective role when fixing the sensor. Utility Model Content

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 , Figure 2 As shown, a fixture for processing a cylindrical shear beam sensor comprises a base 1, an annular fixing plate 3 is fixedly connected to the upper surface of the base 1, an angle adjustment component 2 is slidably connected to the inner wall of the annular fixing plate 3, the outer wall of the lower part of the angle adjustment component 2 is movably sleeved with the inner cavity of the base 1, two symmetrical fixing components 4 are fixedly connected to the left and right sides of the inner wall of the upper part of the angle adjustment component 2, and two symmetrical clamping components 5 are fixedly connected to the opposite surfaces of the two fixing components 4;

[0025] When in use, the two fixing components 4 are used to move the two clamping components 5 toward each other, so that the sensor is clamped and fixed. After fixation, the two fixing components 4 can drive the two clamping components 5 to rotate through the action of the angle adjustment component 2, so as to adjust the angle of the sensor fixedly clamped between the two clamping components 5, thereby facilitating processing.

[0026] like Figure 3 As shown, the angle adjustment assembly 2 includes an annular slide rail 21, the outer wall of the annular slide rail 21 is slidably connected to the inner wall of the annular fixing plate 3, the inner wall of the annular slide rail 21 is fixedly connected to an annular connecting plate 22, and the upper and lower sides of the annular connecting plate 22 are respectively fixedly connected to the inner walls of the lower parts of the two fixing assemblies 4;

[0027] Through the action of the annular slide rail 21, the annular connecting plate 22 can stably and quickly drive the sensor to perform rotational adjustment, thereby ensuring the precision of sensor processing.

[0028] A motor 26 is fixedly connected to the bottom of the inner cavity of the base 1, and a gear 25 is fixedly connected to the output end of the motor 26. A ring gear 24 is meshed on the right side of the outer wall of the gear 25, and an annular sealing plate 23 is fixedly connected to the upper surface of the annular gear 24. The outer walls of the annular sealing plate 23 and the annular gear 24 are movably sleeved with the inner cavity of the base 1 respectively, and the upper surface of the annular sealing plate 23 is fixedly connected to the lower surface of the outer side of the annular slide rail 21;

[0029] The motor 26 rotates the gear 25, thereby rotating the annular sealing plate 23 and the annular gear 24. Under the action of the annular sealing plate 23, the annular connecting plate 22 can drive the two L-shaped fixing blocks 41 to rotate under the action of the annular slide rail 21, so that the fixed sensor can be adjusted in angle, which is convenient for processing.

[0030] like Figure 4As shown, the fixing assembly 4 includes an L-shaped fixing block 41, the inner wall of the lower part of the L-shaped fixing block 41 is fixedly connected to the outer wall of the annular connecting plate 22, the inner cavity of the upper part of the L-shaped fixing block 41 is fixedly connected to the hydraulic rod 42, the output end of the hydraulic rod 42 is fixedly connected to the mounting block 43, the outer wall of the left part of the mounting block 43 is respectively slidably connected to the inner cavity of the upper part of the L-shaped fixing block 41, and two clamping blocks 44 are fixedly connected to one side of the middle part of the mounting block 43 close to the L-shaped fixing block 41, and the two clamping blocks 44 are respectively located at the front and rear sides of the hydraulic rod 42;

[0031] Through the action of the hydraulic rod 42 , the installation block 43 is pushed by the L-shaped fixing block 41 to move the U-shaped clamping plate 51 and the second clamping block 52 , thereby clamping and fixing the sensor.

[0032] like Figure 5 As shown, the clamping assembly 5 includes a rubber sleeve 55, the inner wall of the rubber sleeve 55 is clamped with the outer wall of the mounting block 43, and the inner cavity of the rubber sleeve 55 is fixedly connected with a U-shaped clamping plate 51;

[0033] Through the action of the rubber sleeve 55, the U-shaped clamp 51 will not collide with the mounting block 43 when it is fixedly clamped on the outer wall of the mounting block 43, thereby reducing wear and tear and increasing service life. At the same time, the rubber sleeve 55 can also provide buffering protection when the U-shaped clamp 51 fixes the sensor, thereby ensuring that the sensor is stably clamped without causing damage to it.

[0034] Two second clamping blocks 52 are fixedly connected to one side of the upper and lower parts of the U-shaped clamping plate 51 close to the L-shaped fixing block 41, and the four second clamping blocks 52 are respectively located on the upper and lower sides of the two first clamping blocks 44, and the inner walls of the four second clamping blocks 52 are clamped with a U-shaped limiting frame 54, and the middle parts of the outer walls of the front and rear parts of the U-shaped limiting frame 54 are respectively clamped with the inner walls of the two first clamping blocks 44, and the inner cavity of the middle part of the upper part of the U-shaped limiting frame 54 is movably sleeved with a threaded rod 53, and the lower surface of the threaded rod 53 is fixedly connected to the upper surface of a part of the U-shaped clamping plate 51 close to the L-shaped fixing block 41;

[0035] By clamping the U-shaped clamp 51 and the second clamping block 52 to the outer wall of the mounting block 43, and then passing the U-shaped limit frame 54 through the inner walls of the second clamping block 52 and the first clamping block 44 respectively, the second clamping block 52 and the U-shaped clamp 51 are restricted to the outer walls of the mounting block 43 and the first clamping block 44. At this time, the inner cavity of the upper part of the U-shaped limit frame 54 passes through the outer wall of the threaded rod 53. By rotating the nut, the U-shaped limit frame 54 is restricted between the threaded rod 53 and the U-shaped clamp 51, so that the U-shaped clamp 51 and the mounting block 43 are fixedly connected together, so that the U-shaped clamp 51 can be replaced according to the clamping requirements during use, and it can also be easily disassembled for maintenance or replacement after long-term use.

[0036] The working principle of the utility model is as follows: first, the U-shaped clamping plate 51 and the second clamping block 52 are clamped to the outer wall of the mounting block 43, and then the U-shaped limiting frame 54 passes through the inner walls of the second clamping block 52 and the first clamping block 44 respectively, so that the second clamping block 52 and the U-shaped clamping plate 51 are restricted to the outer walls of the mounting block 43 and the first clamping block 44. At this time, the inner cavity of the upper part of the U-shaped limiting frame 54 passes through the outer wall of the threaded rod 53, and the U-shaped limiting frame 54 is restricted between the threaded rod 53 and the U-shaped clamping plate 51 by rotating the nut, so that the U-shaped clamping plate 51 and the mounting block 43 are fixedly connected together. After being fixed, the mounting block 43 is fixed under the action of the L-shaped fixing block 41 through the action of the hydraulic rod 42. The U-shaped clamp 51 is pushed to move, so that the sensor is clamped and fixed under the action of the two U-shaped clamps 51, wherein the rubber sleeve 55 can provide buffering protection when the U-shaped clamp 51 fixes the sensor. After fixation, the gear 25 is rotated by the action of the motor 26, so that the annular sealing plate 23 and the annular gear 24 are rotated. Under the action of the annular sealing plate 23, the annular connecting plate 22 can drive the two L-shaped fixing blocks 41 to rotate under the action of the annular slide rail 21, so that the fixed sensor can be adjusted in angle, thereby facilitating processing. When the U-shaped clamp 51 needs to be replaced, the nut is turned.
