Description

Technical Field

[0001] This utility model relates to the field of welding processing, and more specifically, to a new type of welding fixture. Background Technology

[0002] Cooling pipes are pipes used for heat dissipation, usually made of metal. They play a very important role in various industrial or production processes, effectively reducing temperature and ensuring the normal operation of machines or equipment. Therefore, cooling pipes are now an indispensable component in hydraulic machinery and CNC machine tools.

[0003] When cooling pipes need to be welded, they are currently held manually or positioned on one side using simple clamps. However, cooling pipes are generally quite long, and this clamping method can easily cause the cooling pipe to wobble during maintenance or welding, resulting in poor welding quality and reduced service life.

[0004] Therefore, it is necessary to propose a new type of welding fixture to solve the above problems. Utility Model Content

[0005] To overcome at least one of the defects (deficiencies) of the prior art, this utility model provides a novel welding fixture.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a new type of welding fixture, including a fixture base plate, a locking component, a fixed clamping plate and a movable clamping plate for clamping the cooling pipe;

[0007] The tooling base plate is provided with multiple parallel positioning holes along the X-axis direction, and the movable clamping plate is fixed on the positioning holes of the tooling base plate by means of locking components that can adjust the position along the X-axis.

[0008] The fixing clamp plate is located in the middle of the tooling base plate;

[0009] The fixed clamp plate is provided with a first workpiece pressure plate;

[0010] The movable clamping plate has a stepped structure along the Y-axis, and a second workpiece pressure plate is provided on the stepped structure. The first and second workpiece pressure plates clamp the cooling pipe. Because the tooling base plate has multiple parallel positioning holes along the X-axis, the movable clamping plate can be installed on the tooling base plate laterally as needed. The stepped structure of the movable clamping plate in the Y-axis direction can fix both sides of the wrapped cooling pipe. In addition, the fixed clamping plate in the middle of the tooling base plate and the first workpiece pressure plate fix the middle of the cooling pipe. Since the entire cooling pipe is fixed from multiple directions, the cooling pipe will not shake, which facilitates the maintenance or welding of the cooling pipe.

[0011] Furthermore, the steps of the movable clamping plate are provided with limiting grooves and positioning mounting holes;

[0012] The second workpiece pressure plate includes a second pressure plate body, a second pressure plate locking post, a cooling pipe locking hole, a cooling pipe clamping screw, a second workpiece connecting hole, a second workpiece positioning screw, and a limiting block that is locked in the limiting groove;

[0013] The second pressure plate body is connected to the second pressure plate locking post, and the limiting block is located at the bottom of the second pressure plate body;

[0014] The cooling pipe locking hole is located on the second pressure plate body, and the cooling pipe clamping screw passes through the cooling pipe locking hole to clamp the cooling pipe;

[0015] The second workpiece connecting hole is located on the second pressure plate locking post. The second workpiece positioning screw passes through the second workpiece connecting hole and is fixed on the positioning mounting hole of the step of the movable fixture plate. Since the step of the movable fixture plate is provided with a limiting groove and a positioning mounting hole, when the second workpiece pressure plate is fixed, the bottom of the second pressure plate body is locked in the limiting groove of the step by the limiting block, and the second pressure plate locking post is locked on the positioning mounting hole of the step. When the cooling pipe needs to be pressed, the cooling pipe can be pressed by passing the cooling pipe pressing screw through the cooling pipe locking hole.

[0016] Furthermore, a buffer pad is provided on the inner side of the second pressure plate body. By setting the buffer pad, direct friction between the cooling pipe and the second pressure plate body can be avoided, thereby protecting both the second pressure plate body and the cooling pipe.

[0017] Furthermore, there are two movable clamping plates, which are symmetrically arranged on the tooling base plates on both sides of the fixed clamping plate. The arrangement of the two movable clamping plates and the two second workpiece pressure plates can clamp both sides of the cooling pipe, resulting in more uniform force distribution and facilitating subsequent welding of the cooling pipe.

[0018] Furthermore, the first workpiece pressure plate includes a pressure plate body, a locking threaded hole, and a clamping screw;

[0019] The pressure plate body is mounted on the fixed clamp plate, and the locking thread hole is located on the pressure plate body;

[0020] The cooling pipe is provided with a cooling pipe holder. The clamping screw passes through the locking thread hole and is clamped onto the cooling pipe holder. The cooling pipe holder can be positioned by the clamping screw passing through the locking thread hole.

[0021] Furthermore, the movable fixture plate has positioning blocks with through holes at both ends, and the tooling base plate has a positioning plate with through holes. The locking member passes through the through holes of the positioning plate and the positioning blocks in sequence and is fixed in the positioning hole of the tooling base plate. The positioning blocks facilitate the easy fixing of the movable fixture plate to the tooling base plate.

[0022] Furthermore, the tooling base plate is also provided with a second positioning hole and a workpiece positioning pin;

[0023] The cooling pipe holder is provided with a connecting piece with a communicating hole, and the connecting piece is fixed to the second positioning hole by screws;

[0024] The workpiece positioning pin limits the two sides of the cooling pipe holder. The second positioning hole can be locked with the connecting piece of the cooling pipe holder, which facilitates the fixing of the cooling pipe holder. The workpiece positioning pin can limit the two sides of the cooling pipe holder, thereby ensuring that the cooling pipe can be firmly set on the tooling base plate.

[0025] Furthermore, the tooling base plate is provided with a handle, which facilitates the handling of the tooling base plate.

[0026] Furthermore, both the base plate and the movable fixture plate are provided with weight-reduction holes. The weight-reduction holes make the new welding fixture lighter and easier to handle, allowing it to be moved to any workstation for welding work as needed.

[0027] Furthermore, the tooling base plate, fixed clamping plate, movable clamping plate, first workpiece pressure plate and second workpiece pressure plate are all made of aluminum alloy. The tooling base plate, fixed clamping plate, movable clamping plate, first workpiece pressure plate and second workpiece pressure plate made of aluminum alloy can effectively reduce the weight of the new welding tooling, making it easier to clamp the cooling pipe and also easier to transport.

[0028] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0029] The novel welding fixture disclosed in this utility model has multiple parallel positioning holes along the X-axis of the fixture base plate. Therefore, the movable clamping plate can be installed on the fixture base plate laterally as needed. The movable clamping plate has stepped steps in the Y-axis direction, which can fix the two sides of the winding cooling pipe. In addition, the middle part of the cooling pipe is fixed by the fixing clamping plate in the middle of the fixture base plate and the first workpiece pressure plate. Since the entire cooling pipe is fixed from multiple directions, the cooling pipe will not shake, which facilitates the maintenance or welding of the cooling pipe. Attached Figure Description

To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0040] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can be described as the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0041] like Figure 1-3 As shown, a novel welding fixture includes a fixture base plate 1, a locking element 2, a fixed fixture plate 4 for clamping a cooling pipe 3, and a movable fixture plate 5. The fixture base plate 1 has multiple parallel positioning holes 6 along the X-axis. The movable fixture plate 5 is fixed to the positioning holes 6 of the fixture base plate 1 by adjusting its position along the X-axis through the locking element 2. The fixed fixture plate 4 is located in the middle of the fixture base plate 1. A first workpiece pressure plate 7 is provided on the fixed fixture plate 4. The movable fixture plate 5 has a stepped step 8 along the Y-axis, and a second workpiece pressure plate 9 is provided on the step 8. The first workpiece pressure plate 7 and the second workpiece pressure plate 9 clamp the cooling pipe 3. The cooling pipe 3 is clamped by multiple parallel positioning holes 6 along the X-axis of the tooling base plate 1. Therefore, the movable clamping plate 5 can be installed on the tooling base plate 1 laterally as needed. The movable clamping plate 5 has a stepped step 8 in the Y-axis direction, so the two sides of the winding cooling pipe 3 can be fixed. In addition, the middle part of the cooling pipe 3 is fixed by the fixing clamping plate 4 in the middle of the tooling base plate 1 and the first workpiece pressure plate 7. Since the entire cooling pipe 3 is fixed by multiple directions, the cooling pipe 3 will not shake, which makes it easy to repair or weld the cooling pipe 3.

[0042] like Figure 4-6As shown, the step 8 of the movable fixture plate 5 is provided with a limiting groove 10 and a positioning mounting hole 11; the second workpiece pressure plate 9 includes a second pressure plate body 12, a second pressure plate locking post 13, a cooling pipe locking hole 14, a cooling pipe clamping screw 15, a second workpiece connecting hole 16, a second workpiece positioning screw 17, and a limiting block 18 locked in the limiting groove 10; the second pressure plate body 12 is connected to the second pressure plate locking post 13, and the limiting block 18 is located at the bottom of the second pressure plate body 12; the cooling pipe locking hole 14 is located on the second pressure plate body 12, and the cooling pipe clamping screw 15 passes through the cooling pipe locking hole 14 to clamp the cooling pipe 3; the second workpiece connecting hole 16 is located on the second pressure plate locking post 13, and the second workpiece positioning screw 17 passes through the second workpiece connecting hole 16 and is fixed to the positioning mounting hole 11 on the step 8 of the movable fixture plate 5. Because the step 8 of the movable fixture plate 5 is provided with a limiting groove 10 and a positioning mounting hole 11, Therefore, when the second workpiece pressure plate 9 is fixed, the bottom of the second pressure plate body 12 is engaged in the limiting groove 10 of the step 8 by the limiting block 18, and the second pressure plate locking post 13 is locked on the positioning mounting hole 11 of the step 8. When the cooling pipe 3 needs to be pressed, the cooling pipe 3 can be pressed by passing the cooling pipe pressing screw 15 through the cooling pipe locking hole 14. A buffer pad 19 is provided on the inner side of the second pressure plate body 12. The buffer pad 19 can prevent the cooling pipe 3 from directly rubbing against the second pressure plate body 12, thus protecting both the second pressure plate body 12 and the cooling pipe 3. In this utility model, there are two movable clamping plates 5. The two movable clamping plates 5 are symmetrically arranged on the tooling base plate 1 on both sides of the fixed clamping plate 4. The arrangement of the two movable clamping plates 5 and the two second workpiece pressure plates 9 can make both sides of the cooling pipe 3 clamped, so that the force is more even and it is convenient for the subsequent welding of the cooling pipe.

[0043] like Figure 7 As shown, the first workpiece pressure plate 7 includes a pressure plate body 33, a locking threaded hole 20, and a clamping screw 21. The pressure plate body 33 is set on the fixed fixture plate 4, and the locking threaded hole 20 is set on the pressure plate body 33. The cooling pipe 3 is provided with a cooling pipe holder 22. The clamping screw 21 passes through the locking threaded hole 20 and is clamped on the cooling pipe holder 22. The clamping screw 21 can be positioned by passing through the locking threaded hole 20. The movable fixture plate 5 is provided with positioning blocks 24 with through holes 23 at both ends. The tooling base plate 1 is provided with a positioning plate 25 with through holes 23. The locking member 2 passes through the through holes 23 of the positioning plate 25 and the positioning block 24 in sequence and is fixed in the positioning hole 6 of the tooling base plate 1. The positioning block 24 facilitates the movable fixture plate 5 to be easily fixed on the tooling base plate 1.

[0044] like Figure 8As shown, the tooling base plate 1 is also provided with a second positioning hole 26 and a workpiece positioning pin 27; the cooling pipe holder 22 is provided with a connecting piece 29 with a communicating hole 28, and the connecting piece 29 is fixed to the second positioning hole 26 by screws 30; the workpiece positioning pin 27 limits the two sides of the cooling pipe holder 22. Through the setting of the second positioning hole 26, it can be locked with the connecting piece 29 of the cooling pipe holder 22, which is convenient for fixing the cooling pipe holder 22. The workpiece positioning pin 27 can limit the two sides of the cooling pipe holder 22, thereby ensuring that the cooling pipe 3 can be firmly set on the tooling base plate 1. The tooling base plate 1 is provided with a handle 31. The fixture base plate 1 is easy to move. Both the fixture base plate 1 and the movable clamping plate 5 are provided with weight reduction holes 32. The weight reduction holes 32 make the new welding fixture lighter and easier to move. It can be moved to any workstation for welding work as needed. In this utility model, the fixture base plate 1, the fixed clamping plate 4, the movable clamping plate 5, the first workpiece pressure plate 7 and the second workpiece pressure plate 9 are all made of aluminum alloy. The fixture base plate 1, the fixed clamping plate 4, the movable clamping plate 5, the first workpiece pressure plate 7 and the second workpiece pressure plate 9 made of aluminum alloy can effectively reduce the weight of the new welding fixture, making it easier to clamp the cooling pipe 3 and also easier to move.

[0045] Example

[0046] In this embodiment, a fixed fixture plate is placed in the middle of the tooling base plate, and a movable fixture plate is placed on both sides of the tooling base plate. Since the tooling base plate has multiple parallel positioning holes along the X-axis, the movable fixture plate can be horizontally adjusted and installed on the tooling base plate according to the clamping requirements of the cooling pipe. The movable fixture plate has stepped steps in the Y-axis direction, so the cooling pipe can be adjusted in the X-axis or Y-axis direction of the movable fixture plate as needed to position and lock the cooling pipe, thereby achieving precise welding.

[0047] When positioning the cooling pipe, the clamping screws on the fixing clamp plate are pressed onto the cooling pipe holder. After the cooling pipe clamping screws pass through the cooling pipe locking hole, the cooling pipe is clamped. In this way, the cooling pipe is fixed, which facilitates the maintenance and welding of the cooling pipe.

[0048] The positional relationships described in the figures are for illustrative purposes only and should not be construed as limiting this patent. Clearly, the above embodiments of this utility model are merely examples to clearly illustrate the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
