Description

Technical Field

[0001] This utility model relates to quartz boat welding, and more specifically to a positioning and clamping device for quartz boat support processing. Background Technology

[0002] Quartz boats, also known as quartz glass, are used as carriers for semiconductor materials and devices due to their excellent optical, electrical, and high-temperature properties. In the production of quartz boats, the connection between structures is mainly achieved by welding. The quality of the welding directly affects the quality of the finished quartz boat. In order to ensure the welding quality, positioning and clamping devices are used to fix the quartz boat to avoid relative displacement during the welding process, which would result in compromised welding quality. Utility Model Content

[0003] The purpose of this invention is to provide a positioning and clamping device for machining quartz boat supports, in order to solve the above-mentioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A positioning and clamping device for quartz boat support processing includes a base, on which symmetrically arranged guide rails are fixedly mounted and a stepper motor is located between two of the guide rails and on one side of the base. The output end of the stepper motor is connected to a transmission lead screw rotatably disposed on the base.

[0006] Two guide rails are symmetrically slidably provided with clamping components to maintain relative movement. The clamping components include a vertical plate and two trapezoidal support plates. The trapezoidal support plates are symmetrically fixed and installed on the outer wall of one side of the vertical plate and flush with its two sides.

[0007] The upper bottom of the trapezoidal plate of the support leg maintains a predetermined distance from the top of the vertical plate, and the top corners of the upper bottom and the hypotenuse are rounded.

[0008] The inclined surfaces of the trapezoidal plates of the two clamping assemblies are adjacent to each other;

[0009] The trapezoidal plate of the support leg is a hard rubber component.

[0010] Preferably, the clamping assembly further includes a base plate, the bottom of the vertical plate and the lower base of the leg trapezoidal plate are both located on the base plate, and the lower base of the leg trapezoidal plate and the apex of the inclined surface are flush with the side of the base plate;

[0011] A sliding seat is symmetrically fixedly arranged on the base plate, and the sliding seat is slidably assembled on the guide rail component;

[0012] The base plate and the transmission lead screw are connected by threads.

[0013] Preferably, a telescopic motor is fixedly installed on the base plate, and the output end of the telescopic motor is connected to the mounting back plate fixedly installed on the back of the vertical plate.

[0014] Preferably, the two vertical plates move toward each other under the drive of the telescopic motor.

[0015] Preferably, a corner plate is fixedly installed on the top of the telescopic motor, and the corner plate has a vertical part.

[0016] Preferably, the vertical part is provided with an elastic plate on the side opposite to the vertical plate.

[0017] Preferably, a protrusion is provided at one end of the elastic plate, and the length of the protrusion is equal to the width of the mounting back plate.

[0018] Preferably, the base plate has a first circular hole located within the space enclosed by the two trapezoidal plates of the support legs and the vertical plate;

[0019] The side wall of the trapezoidal plate of the support leg has two second circular holes arranged vertically.

[0020] In the above technical solution, the positioning and clamping device for processing quartz boat support provided by this utility model has the following beneficial effects: by driving the transmission screw through the stepper motor, the two clamping components are brought closer to each other. Because the entire support trapezoidal plate is a hard rubber part, when the two clamping components are close, the support trapezoidal plate deforms due to contact with the quartz boat support, thereby achieving the fixation of the quartz boat support.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-2 As shown, a positioning and clamping device for quartz boat support processing includes a base 1, on which symmetrically arranged guide rails 2 are fixedly installed, and a stepper motor 3 is located between the two guide rails 2 and on one side of the base 1. The output end of the stepper motor 3 is connected to a transmission screw 4 rotatably arranged on the base 1.

[0028] Two guide rails 2 are symmetrically slidably provided with clamping components 5 to maintain relative movement. The clamping components 5 include a vertical plate 51 and a support trapezoidal plate 52. There are two support trapezoidal plates 52, which are symmetrically fixed and installed on the outer wall of one side of the vertical plate 51 and flush with its two sides.

[0029] The upper bottom of the trapezoidal plate 52 of the support leg maintains a predetermined distance from the top of the vertical plate 51, and the top corners of the upper bottom and the inclined side are rounded corners 521.

[0030] The inclined surfaces of the trapezoidal plates 52 of the two clamping components 5 are adjacent to each other;

[0031] The trapezoidal plate 52 of the support leg is a hard rubber part.

[0032] Specifically, in the embodiment, the inclined surface of the trapezoidal plate 52 of the support leg is a hollow structure and is rectangular by default. When the trapezoidal plate 52 of the support leg abuts against the side wall of the quartz boat support, the trapezoidal plate 52 of the support leg is squeezed and deformed, and the gas in the hollow structure is squeezed into the rounded corner 521, causing the rounded corner 521 to inflate and expand, thereby abutting against the side wall of the quartz boat support, thus achieving an anti-slip effect.

[0033] In the above technology, the stepper motor 3 drives the transmission screw 4, causing the two clamping components 5 to move closer to each other. Since the entire foot trapezoidal plate 52 is made of hard rubber, when the two clamping components 5 are close together, the foot trapezoidal plate 52 deforms due to contact with the quartz boat support, thereby fixing the quartz boat support.

[0034] As a further embodiment of this utility model, the clamping assembly 5 also includes a base plate 53, a vertical plate 51, and the lower base of the support trapezoidal plate 52 is located on the base plate 53, and the lower base and the apex of the inclined surface of the support trapezoidal plate 52 are flush with the side of the base plate 53; a sliding seat 531 is symmetrically fixed on the base plate 53, and the sliding seat 531 is slidably assembled on the guide rail 2; furthermore, the base plate 53 and the transmission screw 4 are threadedly connected.

[0035] Specifically, the base plate 53 is moved by the transmission screw 4. In this embodiment, the trapezoidal support plate 52 is located on the base plate 53 and is arranged adjacent to it.

[0036] As a further embodiment of this utility model, a telescopic motor 56 is fixedly installed on the base plate 53, and the output end of the telescopic motor 56 is connected to the mounting back plate fixedly installed on the back of the vertical plate 51. The two vertical plates 51 move towards each other under the drive of the telescopic motor 56.

[0037] Specifically, when the stepper motor 3 drives the transmission screw 4, causing the two clamping components 5 to move closer to each other, the telescopic motor 56 continues to drive the trapezoidal plate 52 of the support leg to continue to apply force to the side wall of the quartz boat support. When the trapezoidal plate 52 of the support leg abuts against the side wall of the quartz boat support, the trapezoidal plate 52 of the support leg is squeezed and deformed, and the gas in the hollow structure is squeezed into the rounded corner 521, causing the rounded corner 521 to inflate and expand, thereby abutting against the side wall of the quartz boat support, thus achieving an anti-slip effect.

[0038] As a further embodiment of this utility model, a corner plate 57 is fixedly installed on the top of the telescopic motor 56, and the corner plate 57 has a vertical part. An elastic plate 58 is provided on the side of the vertical part opposite to the vertical plate 51. Furthermore, a protrusion 581 is provided at one end of the elastic plate 58, and the length of the protrusion 581 is equal to the width of the mounting back plate.

[0039] Specifically, the elastic plate 58 in the embodiment provides soft contact.

[0040] As a further embodiment of the present invention, the base plate 53 is provided with a first circular hole 532 located in the space enclosed by the two support trapezoidal plates 52 and the vertical plate 51; while the side wall of the support trapezoidal plates 52 is provided with two second circular holes 522 arranged vertically.

[0041] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
