Description

Technical Field

[0001] The utility model belongs to the technical field of fixtures, and particularly relates to a positioning and fixing device for tray welding. Background Art

[0002] A fixture refers to a device used in the mechanical manufacturing process to fix a machining object, make it occupy the correct position, and accept construction or inspection. During the welding process of a workpiece, it is necessary to clamp and fix the workpiece to be welded and enable the workpiece to adjust its position to facilitate the adjustment of the welding angle.

[0003] In the prior art, most of them clamp and fix the workpiece by driving two fixtures to move towards each other through a moving module. During the moving process, it is necessary for the staff to always hold up the workpiece or the manipulator to always grab the workpiece to wait for the two fixtures to be in place and abut and fix the workpiece. This method has a low feeding efficiency and a high equipment cost. Summary of the Utility Model

[0004] In view of the above problems in the prior art, the purpose of the utility model is to provide a positioning and fixing device for tray welding, which clamps and fixes the workpiece through relatively arranged clamping mechanisms and drives the workpiece to rotate by a driving member to facilitate the adjustment of the welding angle.

[0005] A positioning and fixing device for tray welding includes relatively distributed clamping mechanisms for clamping both ends of a workpiece. One of the clamping mechanisms is driven by a driving member to rotate, and the other clamping mechanism rotates with the clamped workpiece; the clamping mechanism includes a rotating disc, a baffle, and a second clamping jaw. The baffle is connected to the rotating disc, the bottom of the baffle is connected with a bottom plate for supporting the workpiece, and a second clamping jaw is installed on the baffle. The second clamping jaw includes a second connecting plate, a third clamping block, and a second locking member. One end of the second connecting plate is connected to the baffle, and the other end is hinged to the third clamping block. The second locking member is installed on the third clamping block.

[0006] Preferably, a groove for the third clamping block to rotate is formed on the second connecting plate. The third clamping block is L-shaped and rotates along the second connecting plate for feeding or clamping and fixing the workpiece.

[0007] Preferably, a first clamping jaw is further installed on the baffle. The first clamping jaw includes a first connecting plate, a first clamping block, a second clamping block, and a first locking member. The first clamping block and the second clamping block are respectively hinged to the first connecting plate, and the first locking member is installed on the second clamping block.

[0008] Preferably, the first connecting plate is Z-shaped, the second clamping block is L-shaped, and the first clamping block and the second clamping block are respectively hinged to both ends of the first connecting plate.

[0009] Preferably, the first locking member and the second locking member are threaded rods. The first locking member rotates on the second clamping block to adjust its position for abutting against the workpiece, and the second locking member rotates on the third clamping block to adjust its position for abutting against the workpiece.

[0010] Preferably, the first clamping jaw is installed at the corner of the baffle. The first clamping block and the second clamping block are respectively located on two adjacent side edges of the baffle, and the first clamping block is used in cooperation with the bottom plate.

[0011] Preferably, the rotating disk is connected to the mounting seat, and the mounting seat is supported on the base through a support frame.

[0012] Preferably, the driving member is a driving motor. The driving motor is installed in the protection box, and the output shaft of the driving motor is drivingly connected to the rotating disk of one of the clamping mechanisms to drive the rotating disk to rotate.

[0013] The beneficial effects of the present utility model are as follows: For this tray welding positioning and fixing device, the distance between the two clamping mechanisms is set according to the workpiece specifications. The first clamping block, the second clamping block, and the third clamping block which are hinged are rotated to create a feeding space, and the workpiece is supported by the bottom plate. Then, the first clamping block, the second clamping block, and the third clamping block are rotated back to the reset position, and the workpiece is abutted and fixed by the force between the first clamping block and the bottom plate. Further, the frame of the workpiece is limited by the L-shaped second clamping block and the third clamping block. Finally, the positions of the first locking member and the second locking member are adjusted to abut and fix the workpiece, realizing the positioning and fixing of the workpiece and avoiding the displacement of the workpiece during welding. In addition, by driving the clamping mechanism and the workpiece to rotate through the driving member, the position and angle of the workpiece can be adjusted to meet different welding requirements.

Among them, the driving member 3 is a driving motor, the driving motor is installed in a protective box, and the output shaft of the driving motor is drivingly connected to the rotating disk 203 of one of the clamping mechanisms 2 to drive the rotating disk 203 to rotate. The two clamping mechanisms 2 clamp and fix both ends of the workpiece 4, and then rely on the driving motor to drive one of the clamping mechanisms 2 to rotate, thereby driving the workpiece 4 and the other clamping mechanism 2 to rotate, facilitating the adjustment of the position of the workpiece 4 during welding to meet the requirements of welding angle and position.

[0023] As Figure 3 、 Figure 5 shown, the clamping mechanism 2 includes a rotating disk 203, a baffle 204 and a second clamping jaw 206. The baffle 204 is connected to the rotating disk 203.

The second clamping jaw 206 includes a second connecting plate 2061, a third clamping block 2062 and a second locking member 2063. One end of the second connecting plate 2061 is connected to the baffle 204, and the other end is hinged to the third clamping block 2062. The second locking member 2063 is installed on the third clamping block 2062. The rotating disk 203 is connected to the mounting base 202, and the mounting base 202 is erected on the base 1 through the support frame 201.

[0024] Specifically, a groove for the third clamping block 2062 to rotate is formed on the second connecting plate 2061. The third clamping block 2062 is L-shaped and rotates along the second connecting plate 2061 for loading or clamping and fixing the workpiece 4.

[0025] The third clamping block 2062 with a rotary hinge setting is rotated to create a loading space. The workpiece 4 is placed between the two clamping mechanisms 2 and supported by the bottom plate 207. Then, the third clamping block 2062 is rotated to limit the frame of the workpiece 4. Finally, the workpiece 4 is abutted and fixed by adjusting the position of the second locking member 2063, realizing the positioning and fixing of the workpiece 4. It should be noted that the workpiece 4 has a frame structure that can be clamped by the third clamping block 2062.

[0026] Embodiment 2

[0027] As Figure 2 、 Figure 3 、 Figure 4 As shown, the structure of this embodiment is basically the same as that in Embodiment 1. The difference lies in that: a first clamping jaw 205 is further installed on the baffle 204 of this embodiment. The first clamping jaw 205 includes a first connecting plate 2051, a first clamping block 2052, a second clamping block 2053, and a first locking member 2054. The first clamping block 2052 and the second clamping block 2053 are respectively hinged to the first connecting plate 2051, and the first locking member 2054 is installed on the second clamping block 2053. The first clamping jaw 205 is installed at the corner of the baffle 204.

The first clamping block 2052 is used in cooperation with the bottom plate 207. The first clamping block 2052 is located above the bottom plate 207, and the workpiece 4 is abutted by the force between the first clamping block 2052 and the bottom plate 207.

[0028] The first connecting plate 2051 is Z-shaped, and the second clamping block 2053 is L-shaped. The first clamping block 2052 and the second clamping block 2053 are respectively hinged to both ends of the first connecting plate 2051, and cooperate with the baffle 204 to clamp the workpiece 4.

[0029] The first locking member 2054 and the second locking member 2063 are threaded rods. The first locking member 2054 rotates on the second clamping block 2053 to adjust the position for abutting the workpiece 4, and the second locking member 2063 rotates on the third clamping block 2062 to adjust the position for abutting the workpiece 4.

[0030] Among them, the number of the first clamping jaws 205 and the second clamping jaws 206 is not fixed and is set according to the structure of the workpiece 4. In this embodiment, two first clamping jaws 205 and two second clamping jaws 206 are provided in one clamping mechanism 2, and one first clamping jaw 205 and three second clamping jaws 206 are provided in the other clamping mechanism 2.

[0031] Working principle: When using this tray welding positioning and fixing device, adjust the distance between the two clamping mechanisms 2 according to the specifications of the workpiece 4, and then rotate the first clamping block 2052, the second clamping block 2053 and the third clamping block 2062 to facilitate the loading of the workpiece 4. Place the workpiece 4 between the two clamping mechanisms 2, rely on the bottom plate 207 to support the workpiece, and then rotate the first clamping block 2052, the second clamping block 2053 and the third clamping block 2062 to the reset position, so that the first clamping block 2052 and the bottom plate 207 abut against the workpiece 4, and the L-shaped second clamping block 2053 and the third clamping block 2062 clamp the border of the workpiece 4. Then, adjust the positions by rotating the first locking member 2054 and the second locking member 2063, so that the first locking member 2054 and the second locking member 2063 abut against and fix the workpiece 4 for welding. During the welding process, the driving motor can be started to drive one of the clamping mechanisms 2 to rotate, thereby driving the workpiece 4 to rotate, so as to adjust the position and angle of the workpiece 4 to meet the welding requirements.
