Description

Technical Field

[0001] The utility model relates to the technical field of woodworking knife production, in particular to a welding jig and welding equipment. Background Art

[0002] With the development of woodworking carving technology, the application of woodworking tools is also increasing. Conventional woodworking tools include a handle section and a blade section. One end of the handle section is connected to the power tool, and the other end is coaxially connected to the blade section. The blade section is connected to a blade. Under the action of the power tool, the tool can be rotated, thereby driving the blade to rotate to process the workpiece. In order to ensure the strength of the woodworking knife, the handle section and the blade section are often fixed by welding.

[0003] Usually, before welding, the tool handle segment needs to be placed in a preset posture to facilitate welding the blade segment to the tool handle segment. However, in the process of clamping the tool handle segment with an existing welding jig, the staff needs to place the tool handle segment in the jig in a preset posture, and then lock the tool handle segment by controlling the locking mechanism of the welding jig. However, during the locking process, the tool handle segment is easily offset, resulting in a deviation between the tool handle segment and the blade segment during welding. Therefore, during the locking process, the staff needs to correct the posture of the tool handle segment. The whole process is relatively cumbersome, resulting in a decrease in overall production efficiency.

[0004] Therefore, the above problems need to be solved urgently. Utility Model Content

[0039] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0040] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] In the present utility model, unless otherwise clearly specified and limited, the first feature being "above" or "below" the first feature may include the first and first features being in direct contact, and may also include the first and first features being in contact not directly but through another feature between them. Moreover, the first feature being "above", "above" and "above" the first feature includes the first feature being directly above and obliquely above the first feature, or simply indicates that the first feature is higher in level than the first feature.

In addition, the terms "first" and "first" are only used to distinguish in the description and have no special meaning.

[0043] Usually, before welding, the tool handle segment needs to be placed in a preset posture to facilitate welding the blade segment to the tool handle segment. However, in the process of clamping the tool handle segment with an existing welding jig, the staff needs to place the tool handle segment in the jig in a preset posture, and then lock the tool handle segment by controlling the locking mechanism of the welding jig. However, during the locking process, the tool handle segment is easily offset, resulting in a deviation between the tool handle segment and the blade segment during welding. Therefore, during the locking process, the staff needs to correct the posture of the tool handle segment. The whole process is relatively cumbersome, resulting in a decrease in overall production efficiency.

[0044] Based on the above, please refer to Figure 1 to Figure 2 In the embodiment, a welding device is provided, which includes a welding mechanism and a welding jig. Before the welding mechanism is used to weld the handle segment 200 and the blade segment, the handle segment 200 is first fixed by the welding jig. Under the action of the welding jig, the handle segment 200 can be quickly clamped, thereby improving the welding efficiency between the handle segment 200 and the blade segment during the production process of the tool.

[0045] To this end, the present embodiment also proposes a clamping welding jig for the shank segment 200, which includes a positioning mechanism 1 and a clamping mechanism 2. The positioning mechanism 1 includes a positioning member 11, which can abut against the outer peripheral wall of the shank segment 200; the clamping mechanism 2 includes a clamping member 21, a first reset member 22 and a first limit member 23. The positioning member 11 is arranged opposite to the clamping member 21, and the positioning member 11 and the clamping member 21 can form a clamping structure adapted to the shank segment 200. The first limit member 23 is arranged on the side of the clamping member 21 away from the positioning member 11. The length direction of the first reset member 22 is along the first direction. The first reset member 22 is placed between the clamping member 21 and the first limit member 23, and can undergo elastic deformation when the clamping member 21 is away from the positioning member 11, so as to have elastic potential energy for restoring the deformation and pushing the clamping member 21 to approach the positioning member 11.

[0046] It can be understood that before clamping the handle segment 200, a force is applied to the clamping member 21, so that the clamping member 21 can be moved in a direction away from the positioning member 11, thereby compressing the first resetting member 22, and then the handle segment 200 is placed between the positioning member 11 and the clamping member 21 in a preset posture, and then the force acting on the clamping member 21 is withdrawn. Under the action of the first resetting member 22, the clamping member 21 can be moved closer to the positioning member 11, thereby completing the clamping of the handle segment 200. Under the action of this welding jig, it is not only easy to operate, but also can improve the clamping efficiency of the woodworking knife.

[0047] The clamping member 21 includes a first clamping body 211 and two first clamping portions 212. The two first clamping portions 212 are convexly arranged on one side of the first clamping body 211 close to the clamping member 21, and the outer peripheral walls of the two first clamping portions 212 can be tangent to the outer peripheral wall of the handle segment 200. It can be understood that the two first clamping portions 212 are respectively located on both sides of the handle segment 200, and under the action of the first reset member 22, they can be tangent to the outer peripheral wall of the handle body, so as to prevent the handle segment 200 from deviating to the two sides of the clamping during the clamping process. In addition, the shape of the first clamping portion 212 is preferably cylindrical.

[0048] The clamping mechanism 2 further includes a first guide rod 24 and a first guide block 25. The length direction of the first guide rod 24 is consistent with the first direction. The first guide block 25 is slidably arranged on the first guide rod 24, and the clamping member 21 is arranged on the top of the first guide block 25. The clamping member 21 can drive the first guide block 25 to slide on the first guide rod 24 during the movement. This arrangement allows the clamping member 21 to deviate during the movement, thereby ensuring the accuracy of the clamping member 21 when clamping the tool handle segment 200. The first reset member 22 is preferably a spring, and the spring is sleeved on the outer periphery of the first guide rod 24.

[0049] When the clamping member 21 is clamping the handle segment 200, the positioning member 11 can also exert a reaction force on the handle segment 200 to keep the handle segment 200 in a stationary state. At this time, the positioning member 11 can be fixed or movable, and the moving direction of the positioning member 11 is opposite to the moving direction of the clamping member 21. In this embodiment, the positioning member 11 is preferably movable to ensure that the handle segment 200 can be kept in a stable state during the clamping process.

[0050] Specifically, the positioning mechanism 1 further includes a second reset member 12 and a second limit member 13. The second limit member 13 is arranged on the side of the positioning member 11 away from the clamping member 21. The second reset member 12 is arranged between the clamping member 21 and the second limit member 13, and can be elastically deformed when the clamping member 21 is away from the positioning member 11, so as to have elastic potential energy to restore the deformation and push the clamping member 21 to approach the positioning member 11. It can be understood that before clamping the handle segment 200, while the clamping member 21 moves in a direction away from the positioning member 11, the positioning member 11 can move in a direction away from the clamping member 21. The movable clamping member 21 and the positioning member 11 can not only meet the clamping of different types of handle segments 200, but also ensure that the handle segment 200 is subjected to the action of two directions when being clamped, so as to ensure the stability of the handle segment 200.

[0051] Furthermore, the positioning member 11 includes a second clamping body 111 and two second clamping parts 112. The two second clamping parts 112 are convexly arranged on one side of the second clamping body 111 close to the clamping member 21, and the outer peripheral walls of the two second clamping parts 112 can be tangent to the outer peripheral wall of the handle segment 200; the two first clamping parts 212 and the two second clamping parts 112 together constitute a clamping structure. It can be understood that the two first clamping parts 212 and the two second clamping parts 112 are respectively arranged correspondingly, and in the process of clamping the handle segment 200, the two first clamping parts 212 and the two second clamping parts 112 can respectively apply clamping force to the body of the handle segment 200 to keep the handle segment 200 in a stable state.

[0052] The positioning mechanism 1 also includes a second guide rod 14 and a second guide block 15. The length direction of the second guide rod 14 is consistent with the direction in which the second reset member 12 recovers its deformation. The second guide block 15 is slidably arranged on the second guide rod 14, and the clamping member 21 is arranged on the top of the second guide block 15. The positioning member 11 can drive the second guide block 15 to slide on the second guide rod 14 during the movement. This arrangement allows the positioning member 11 to deviate during the movement, thereby ensuring the accuracy of the positioning member 11 when clamping the tool handle segment 200. The second reset member 12 is preferably a spring, and the spring is sleeved on the outer periphery of the second guide rod 14.

[0053] In some other feasible embodiments, the first guide rod 24 is integrally provided with the second guide rod 14. And the number can be determined according to actual working conditions.

[0054] Before clamping the tool handle segment 200, the clamping member 21 needs to be separated from the positioning member 11 by an external driving mechanism. The driving mechanism may include one power source 100 or two power sources 100. When one power source 100 is provided, a force can be applied to the clamping member 21 and the positioning member 11 to move away from each other at the same time. When two power sources 100 are provided, the two power sources 100 can apply forces to the clamping member 21 and the positioning member 11 respectively, and the directions of the two forces are opposite, so that the clamping member 21 and the positioning member 11 move away from each other. It should be noted that the power source 100 is preferably a linear driving mechanism such as a cylinder.

[0055] In this embodiment, one power source 100 is preferred. For this purpose, the welding jig further includes a connecting mechanism 3, which is disposed between the positioning mechanism 1 and the clamping mechanism 2, and the connecting mechanism 3 is configured to enable the positioning member 11 and the clamping member 21 to move in opposite directions at the same time. It can be understood that under the action of the connecting mechanism 3, the clamping member 21 and the positioning member 11 can be moved in opposite directions. Compared with two power sources 100 that can apply forces to the clamping member 21 and the positioning member 11 respectively to move the clamping member 21 and the positioning member 11 away from each other, one power source 100 can ensure a reduced input amount to improve the stability of the welding jig when clamping the tool handle segment 200.

[0056] In this embodiment, the connection mechanism 3 includes a first connection block 31, a first connection rod 32 and a second connection rod 33. The first connection block 31 is arranged on one side of the positioning member 11 along the second direction, and the first connection block 31 can move along the second direction, and the first direction is arranged perpendicular to the second direction; one end of the first connection rod 32 is rotatably connected to the first connection block 31, and the other end is rotatably connected to the clamping member 21; one end of the second connection rod 33 is rotatably connected to the first connection block 31, and the other end is rotatably connected to the positioning member 11. It can be understood that the external power source 100 acts on the first connection block 31, so that the first connection block 31 can be pushed to move closer in the second direction, and then the clamping member 21 can be pushed to move in the direction away from the positioning member 11 under the action of the first connection rod 32, that is, the first reset member 22 can be compressed under the action of the first connection rod 32.

[0057] Further, in order to ensure the stability of the clamping member 21 during the movement with the positioning member 11, the connecting mechanism 3 also includes a second connecting block 34, a third connecting rod 35 and a fourth connecting rod 36. The second connecting block 34 is arranged on the other side of the positioning member 11 along the second direction, and the second connecting block 34 can move along the second direction; one end of the third connecting rod 35 is rotatably connected to the second connecting block 34, and the other end is rotatably connected to the clamping member 21; one end of the fourth connecting rod 36 is rotatably connected to the second connecting block 34, and the other end is rotatably connected to the positioning member 11. It can be understood that the first reset member 22 can drive the second connecting block 34 to move along the second direction through the third connecting rod 35 during the compression process. Similarly, the second reset member 12 can drive the second connecting block 34 to move along the second direction through the fourth connecting rod 36 during the compression process. The second connecting block 34, the third connecting rod 35 and the fourth connecting rod 36 can improve the stability of the clamping member 21 during the movement with the positioning member 11. In addition, the first connecting block 31 , the first connecting rod 32 and the second connecting rod 33 on one side of the clamp 21 and the second connecting block 34 , the third connecting rod 35 and the fourth connecting rod 36 on the other side of the clamp 21 are symmetrically arranged with respect to the clamped tool handle segment 200 .

[0058] In addition, the connecting mechanism 3 further comprises a plurality of guide columns, the length direction of all the guide columns is consistent with the second direction, and the first connecting block 31 and the second connecting block 34 are both slidably connected to the guide columns. It can be understood that the guide columns are convenient for preventing the first connecting block 31 from deflecting during movement.

[0059] The welding jig further includes a support seat 4 and a positioning plate 5, wherein the positioning plate 5 is disposed on the top of the support seat 4, and the positioning plate 5 includes a positioning hole, and the positioning member 11 and the clamping member 21 are symmetrically disposed about the axis of the positioning hole. It can be understood that the positioning mechanism 1 and the clamping mechanism 2 are both disposed on the support seat 4, wherein the first limiting member 23 and the second limiting member 13 are respectively disposed on the two side walls of the support seat 4 opposite to each other along the first direction, and the two ends of the guide column are connected to fixed seats, and the two fixed seats are respectively connected to the two side walls of the support seat 4 opposite to each other along the second direction.

[0060] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
