Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of welding of a view mirror and a solenoid valve pipeline, in particular to a welding and fixing tool for a view mirror and a solenoid valve pipeline. BACKGROUND

[0002] A view mirror and a solenoid valve pipeline are installed in a semiconductor temperature control device. Before the view mirror and the solenoid valve pipeline are installed, the view mirror, the solenoid valve and a copper pipe need to be pre-welded. After the view mirror, the solenoid valve and the copper pipe are welded together, the welded view mirror and the solenoid valve pipeline are assembled into the semiconductor temperature control device.

[0003] At present, the pre-welding step is to assemble the view mirror, the solenoid valve and the copper pipe together to form a set of the view mirror, the solenoid valve and the copper pipe, then the bench vice clamps the two sides of the copper pipe at the welding area to fix the copper pipe, and then the welding area is welded one by one.

[0004] The inventor of the present application finds that in the welding process, the high temperature of the welding flame softens the copper pipe at the welding area. The bench vice clamps the copper pipe to generate a clamping force on the copper pipe. The copper pipe under high temperature deforms under the action of the clamping force. The different clamping positions and clamping forces each time result in different shapes of the copper pipe after each welding. Therefore, such a pre-welding method causes the outer dimensions of the copper pipe after welding of the view mirror, the solenoid valve and the copper pipe to be inconsistent, which further affects the smooth installation of the view mirror and the solenoid valve pipeline into the semiconductor temperature control device. Moreover, the bench vice can damage the view mirror, the solenoid valve and the copper pipe. The single welding one by one is slow and has low welding efficiency.

[0005] The content of the background section merely represents the known technology of the discloser, and does not necessarily represent the state of the art in this field. CONTENT OF THE PRESENT DISCLOSURE

[0006] To solve at least one of the above technical problems, the present application provides a welding and fixing tool for a view mirror and a solenoid valve pipeline.

[0007] According to one aspect of the present application, a welding and fixing tool for a view mirror and a solenoid valve pipeline is disclosed, comprising a base and a view mirror fixing part.

The valve head fixing part is provided with at least two valve head limiters. The shape of the valve head limiters matches the shape of the valve head to fix the valve head. The support part comprises a first support plate and a second support plate. The first support plate and the second support plate are arranged in the vertical direction and are arranged on both sides of the valve head fixing part and connected with the base plate to support the fixing tool. The view mirror fixing part is arranged at the top end of the second support plate. The view mirror fixing part is provided with at least two view mirror limiters to fix the view mirror.

[0008] Optionally, the middle part of the first support plate and / or the second support plate is a through hole. The bottom of the through hole has at least two valve seat limiters. The shape of the valve seat limiters matches the shape of the valve seat to fix the valve seat.

[0009] Optionally, the valve head limiter is a trapezoidal groove. The trapezoidal groove matches the valve head to fix the valve head.

[0010] Optionally, the valve seat limiter is a trapezoidal groove. The trapezoidal groove matches the valve seat to fix the valve seat.

[0011] Optionally, the view mirror limiter is a square groove. The square groove matches the view mirror limiter to fix the view mirror.

[0012] Optionally, the height of the first support plate is less than the height of the second support plate.

[0023] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order.

[0024] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] like Figure 2 As shown, the sight glass and solenoid valve pipeline includes a sight glass 12 and a solenoid valve 13. The solenoid valve 13 includes a valve head 15 and a valve seat 14. The sight glass 12 and the solenoid valve 13 are connected together by a copper pipe.

[0026] Implement according to the example, for exampleFigure 1 As shown, the welding and fixing fixture for the sight glass and solenoid valve pipeline includes a base 1 and a sight glass fixing part 2. The base 1 includes a base plate 3, a valve head fixing part 6, and a support part 11. (As shown...) Figure 1 In the three-dimensional coordinate system shown, the x-axis and y-axis are horizontal, and the z-axis is vertical. The base plate 3 is arranged horizontally. The valve head fixing part 6 is disposed on the base plate 3 and arranged along the z-axis. The valve head fixing part 6 has at least two valve head limiting members 7. The shape of the valve head limiting members 7 matches the shape of the valve head 15 to fix the valve head 15. The support part 11 includes a first support plate 4 and a second support plate 5. The first support plate 4 and the second support plate 5 are arranged along the z-axis and are located on both sides of the valve head fixing part 6, connected to the base plate 3 to support and fix the fixture.

[0027] The sight glass fixing part 2 is located at the top of the second support plate 5. The sight glass fixing part 2 is provided with at least two sight glass limiting members 9 to fix the sight glass 12. The at least two sight glass limiting members 9 correspond to the center of at least two valve head limiting members 7.

[0028] For example, the base 1 and the sight glass fixing part 2 can be made of materials with good stability and high temperature resistance, such as metal materials, such as aluminum, stainless steel, etc. The bottom ends of the first support plate 4 and the second support plate 5 can be kept horizontal to improve the stability of the base 1.

[0029] For example, the valve head fixing part 6 can be fixedly connected to the base plate 3 in various ways, such as welding, riveting, bolting, etc. For example, Figure 1 As shown, the valve head fixing part 6 can be disposed at the center of the substrate 3 and perpendicular to the substrate 3. The valve head fixing part 6 can be provided with at least two valve head limiting members 7. Five valve head limiting members 7 are shown in the figure, but this application does not limit the specific number of valve head limiting members 7.

[0030] The shape of the valve head limiting member 7 matches the shape of the valve head 15 to fix the valve head 15. For example, the valve head limiting member 7 can be a trapezoidal groove that matches the valve head 15 to fix the valve head 15 to the trapezoidal groove.

[0031] For example, before welding the sight glass and solenoid valve piping, the sight glass 12, solenoid valve 13, and copper pipe are assembled together, and then the valve head 15 is placed into the valve head limiting member 7. The bottom surface of the valve head 15 is brought into contact with the surface of the valve head limiting member 7 to fix the valve head 15. Then, the sight glass 12 is placed into the sight glass limiting member 9 to fix the sight glass 12. After fixing the valve head 15 and the sight glass 12, the connection between the sight glass 12 and the copper pipe, and the connection between the solenoid valve 13 and the copper pipe are welded.

[0032] Through the above embodiment, at least two sets of valve head limiters and valve seat limiters are arranged. At least two sets of sight glasses and solenoid valve pipelines can be fixed at the same time to weld at least two sets of sight glasses and solenoid valve pipelines at the same time, thereby improving the welding efficiency. The fixing position is at the valve head and the sight glass, which reduces the clamping force on the valve head and the sight glass, and does not need to clamp the copper pipe. In this way, the copper pipe will not deform under the action of the clamping force during welding, improving the consistency of the size of the copper pipe in the welded sight glass and solenoid valve pipeline, thereby facilitating the smooth installation of the sight glass and solenoid valve pipeline to the semiconductor temperature control equipment.

[0033] According to an example embodiment, as shown in Figure 1 The first support plate 4 can be connected with one side of the base plate 3. The second support plate 5 can be connected with the other side of the base plate 3. The other side is the opposite side of the base plate 3 from the one side. The first support plate 4 and the second support plate 5 are arranged in parallel along the z-axis direction. The first support plate 4 and the second support plate 5 are both arranged perpendicularly to the base plate 3.

[0034] The first support plate 4 and / or the second support plate 5 can be detachably connected with the base plate 3. For example, the first support plate 4 and / or the second support plate 5 can be connected with the base plate 3 by bolt connection, clamping, riveting, etc. The first support plate 4 and / or the second support plate 5 can also be fixedly connected with the base plate 3, such as welding. The first support plate 4 and / or the second support plate 5 can also be integrally formed with the base plate 3.

[0035] The middle part of at least one of the first support plate 4 and the second support plate 5 can be provided with a through hole 10. As shown in Figure 1 The middle part of the second support plate 5 is provided with a through hole 10. The bottom of the through hole 10 can be provided with at least two valve seat limiters 8. In the case that the first support plate 4 and the second support plate 5 are both provided with a through hole 10, at least one of the through hole 10 of the first support plate 4 and the through hole 10 of the second support plate 5 is provided with at least two valve seat limiters 8.

[0036] For example, the cross section of the valve seat 14 is circular. The shape of the valve seat limiter 8 can be semicircular or trapezoidal. The shape of the valve seat limiter 8 matches the shape of the valve seat 14 to fix the valve seat 14.

[0037] By providing a through hole in the middle part of the first support plate and / or the second support plate, the welding flame and sparks generated during welding can pass through the through hole, reducing the ejection of the welding flame and sparks generated during welding, thereby reducing the probability of the welding flame and sparks generated during welding hitting the welder. And welding can be done on the side of the through hole during welding. By providing a through hole, the welding operation space is improved.

[0038] For example, the valve seat limiter 8 can be a square groove. The square groove matches the valve seat limiter 8 to fix the sight glass 12 to the square groove.

[0039] For example, the height of the first support plate 4 is smaller than the height of the second support plate 5. Welding is performed from the side of the first support plate 4, and the welding operation space can be increased.

[0040] Finally, it should be noted that the above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Although the present application is described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions of the foregoing embodiments or make equivalent replacements to some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
