Description
Technical Field
[0001] The invention relates to the technical field of welding, and in particular to a guiding positioning detection component. Background Art
[0002] When welding, the parts need to be aligned and then welded using a welding gun;
[0003] When welding the sides of some special-shaped parts, the existing alignment method is mostly to manually stack the two parts together and judge whether the sides of the parts are aligned by the naked eye. Since there will be certain errors in manual operation, it is easy to cause a certain misalignment between the two special-shaped parts, resulting in unqualified welded parts. In addition, during welding, due to problems with the production processes of the two parts, the two parts may not be completely aligned, resulting in a certain misalignment. Since the distance of this misalignment is very small and cannot be observed by the naked eye, it is easy to cause unqualified welded parts during welding. Therefore, it is necessary to design a guidance and positioning detection component to solve the above problems. Summary of the invention
[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art, and a guiding positioning detection component is proposed. Through the setting of a positioning pin, a limit column and two push rods, when welding, when two parts are put on the positioning pin, the two push rods can be synchronously moved to the left so that the sides of the two parts can be quickly aligned, thereby improving the welding efficiency of the parts. Moreover, through the setting of the gear rack, when the parts are misaligned up and down, the misalignment distance can be enlarged, thereby timely correcting the position of the parts and ensuring the stability of the welding quality.
[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] Preferably, both the front and rear sides of the rectangular plate are fixedly connected with fixing plates, and the opposite sides of the two fixing plates are commonly fixedly connected with a second shell.
[0010] Preferably, an L-shaped block is fixedly connected to the right side of the rectangular plate, two fixed blocks are fixedly connected to the upper end of the L-shaped block, the opposite sides of the two fixed blocks are fixedly connected to the first rack, the upper ends of the two fixed plates are fixedly connected to the second slide rail, the two second slide rails are slidably connected with sliders, the upper ends of the two sliders are fixedly connected to square blocks, the upper ends of the two square blocks are fixedly connected to sensing blocks, the upper ends of the two fixed plates are fixedly connected to fixed seats, the two fixed seats are fixedly connected with sensors, the upper ends of the two square blocks are fixedly connected to the second rack, the right sides of the two matching linear bearings are commonly fixedly connected to a connecting block, and the opposite sides of the two connecting blocks are rotatably connected with gears.
[0011] Preferably, the two gears are meshed with the corresponding first rack and second rack.
[0012] Compared with the existing technology, the advantages of this device are:
[0013] 1. Compared with the prior art, by setting the positioning pin, the limiting column and the two push rods, when aligning, the two parts are put on the positioning pin, and the two push rods can be moved to the right by the operation of the cylinder, so that the two parts rotate around the positioning pin, so that the sides of the two parts can be quickly aligned;

DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

[0021] The limiting assembly includes a positioning pin 2 fixed to the upper end of the welding seat 1, and the upper end of the welding seat 1 is fixedly connected to a limiting column 3.
[0022] Among them, the outer side of the guide cylinder 26 is fixedly connected to the first shell 6, the left sides of the two positioning blocks are commonly fixedly connected to the guide plate 5, the guide plate 5 is provided with a rectangular opening, and the two push rods 4 pass through the rectangular opening, the front and rear sides of the rectangular plate 14 are fixedly connected to the fixing plates 25, and the opposite sides of the two fixing plates 25 are commonly fixedly connected to the second shell 7.
[0023] Among them, the right side of the rectangular plate 14 is fixedly connected with an L-shaped block, the upper end of the L-shaped block is fixedly connected with two fixed blocks 16, the opposite sides of the two fixed blocks 16 are fixedly connected with the first rack 17, the upper ends of the two fixed plates 25 are fixedly connected with the second slide rail 20, the two second slide rails 20 are slidably connected with sliders 21, the upper ends of the two sliders 21 are fixedly connected with square blocks 28, the upper ends of the two square blocks 28 are fixedly connected with sensing blocks 22, the upper ends of the two fixed plates 25 are fixedly connected with fixed seats 24, the two fixed seats 24 are fixedly connected with sensors 23, and a controller is provided externally. The sensor 23 will move according to the distance of the sensing block 22 into the sensor 23. When the distances entered are the same, the sensor 23 will generate the same electrical signal, indicating that the sides of the two parts are flush. When the signals generated by the sensor 23 are different, the controller will process the signal information to determine whether the parts are aligned. The upper ends of the two square blocks 28 are fixedly connected to the second rack 19, and the right sides of the two matching linear bearings 27 are fixedly connected to the connecting blocks 29. The opposite sides of the two connecting blocks 29 are rotatably connected to the gears 18. The two gears 18 are meshed with the corresponding first rack 17 and the second rack 19, so that the misalignment distance of the parts can be amplified, which is convenient for the sensor 23 to detect.
[0024] The functional principle of the present invention can be explained through the following operation mode: before welding, the two parts are sequentially sleeved on the positioning pin 2, so that the two parts are stacked together, and the staff starts the cylinder 11, so that the U-shaped block 12 drives the rectangular plate 14 to move left, so that the guide cylinder 26, the linear bearing 27, the two positioning blocks, the guide plate 5 and the two push rods 4 move left, so that the two parts rotate around the positioning pin 2, and when the two parts contact the limit column 3, the continued movement of the cylinder 11 will cause the multiple linear bearings 27 to move right, so that the spring 15 is compressed, and the parts are tightly pressed between the push rod 4 and the limit column 3;
[0025] When the linear bearing 27 moves to the right, the two connecting blocks 29 drive the two gears 18 to move to the right. Since the first rack 17 is in a fixed state, the two second racks 19 move to the right, so that the two square blocks 28 drive the two sensing blocks 22 to move to the right, so that the two sensing blocks 22 pass through the sensor 23. At this time, it can be judged whether the side surfaces of the two parts are completely flush according to the electrical signal generated by the sensor 23.
[0026] When the electrical signals generated by the two sensors 23 are exactly the same, it means that the sides of the two parts are flush. When the signals generated by the two sensors 23 are different, the controller will process the signal to remind the staff that the sides of the two parts are not aligned, and the staff needs to correct the position of the parts in time.
[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
