Technical Field

[0001] This utility model relates to the field of automotive welding fixtures, and in particular to a fixture switching tooling. Background Technology

[0002] With the development of the automotive industry, the pace of vehicle model updates and iterations is very rapid. Car manufacturers cannot predict the product lifecycle. The tooling used for welding the body-in-white requires a certain amount of time and cost from research and development to production. Therefore, in actual production, it is not uncommon for multiple tooling sets to coexist in automotive welding.

[0003] In existing technologies, welding fixtures can be switched manually by using overhead cranes or forklifts. However, the positioning accuracy of manual overhead cranes is poor, and a suspension structure is required for fixture transfer, making the structure complex and the operation difficult. Alternatively, an automated switching structure can be customized for each type of fixture to switch between fixtures with specific characteristics or types. However, such customized mechanisms have poor adaptability and occupy a large area, resulting in high research and development and production costs.

[0004] Therefore, existing fixture switching solutions for multiple tooling coexistence still suffer from poor adaptability, complex structure, inconvenient maintenance, and high production costs. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, such as high difficulty in operation or inconvenient maintenance and high production cost, and to provide a fixture switching tooling.

[0006] The objective of this utility model can be achieved through the following technical solutions: A fixture switching tooling is used for switching fixtures set on a slide table in a welding process. The tooling includes a moving trolley and a positioning garage.

[0008] Preferably, the fixed base is equipped with a plurality of support rollers and limiting rollers along the moving direction of the clamp, and the support rollers and limiting rollers are distributed at equal intervals and cross each other, and the moving direction of the clamp is perpendicular to the moving direction of the slide.

[0009] Preferably, the mobile trolley is provided with positioning pulleys on both sides, and the positioning garage is provided with positioning plates on both sides. The positioning plates are vertically arranged, the rotation center axis of the positioning pulleys is parallel to the positioning plates, and the positioning pulleys abut against the positioning plates.

[0010] Preferably, the slide is provided with a receiving pulley group corresponding to the transfer pulley group, and the receiving pulley group has the same structure as the transfer pulley group.

[0011] Preferably, the end of the mobile trolley away from the slide table is provided with a clamp positioning component, and an elastic protective pad is fixed on the side of the clamp positioning component facing the clamp.

[0024] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted.

[0025] Example 1 like Figures 1 to 4 As shown, this embodiment provides a fixture switching tooling for switching fixtures set on the slide table 1 in the welding process. The tooling includes a moving trolley 2 and a positioning garage 3. The upper end of the mobile trolley 2 is provided with a transfer pulley group 21, and the lower end of the clamp 5 is provided with a guide rail 4. The clamp is movably mounted on the transfer pulley group 21 via the guide rail 4. The clamp 5 is provided with a positioning mounting hole, and the mobile trolley 2 is provided with a fixing pin. The clamp is detachably mounted on the mobile trolley 2 via the fixing pin. The positioning garage 3 is fixed on one side of the initial position of the slide table 1, and the positioning garage 3 cooperates with the mobile trolley 2. The positioning garage 3 is provided with a fixing component for fixing the mobile trolley 2.

[0026] Working principle: The workpiece fixture to be welded is placed on the mobile trolley 2 and fixed in place by the fixing pin. The mobile trolley 2 is then transferred to the positioning garage 3 and positioned and fixed by the fixing components. The slide table 1 is moved to the initial position, the fixing pin is opened, and the fixture is transferred to the slide table 1 based on the transfer pulley block and guide rail. Then the slide table moves to the corresponding position for welding operation.

[0027] The needle is loaded with different fixtures via a moving trolley and interacts with the same slide table via a positioning garage. The pulley and rail structure allows for easy switching of fixtures on the slide table, making operation convenient and facilitating the maintenance and storage of tooling fixtures, resulting in low maintenance costs. Moreover, the overall tooling structure is simple, enabling the switching of welding fixtures for multiple vehicle models, making it flexible in use and widely applicable.

[0028] Preferred implementation methods, such as Figure 4 As shown, the transfer pulley block 21 includes a fixed base 22 and a support roller 23 and a limiting roller 24 rotatably mounted on the fixed base 22. The guide rail 4 includes a horizontal plate 41 and a vertical plate 42. The rotation center axis of the support roller 23 is perpendicular to the vertical plate 42, the rotation center axis of the limiting roller 24 is perpendicular to the horizontal plate 41, the upper end of the support roller 23 abuts against the horizontal plate 41, and the outer circumference of the limiting roller 24 abuts against the vertical plate 42.

[0029] Two sets of parallel transfer pulleys 21 are installed above the moving trolley. Each transfer pulley 21 has support rollers 23 and limiting rollers 24 with perpendicular rotating shafts. An L-shaped horizontal plate 41 and a vertical plate 42 are installed at the bottom of the moving trolley. The rolling contact between the horizontal plate 41 and the support rollers 23 reduces friction, facilitating easy and time-saving transfer of the clamp. Furthermore, the rolling contact between the vertical plates 42 and the horizontal limiting rollers 24 allows for positioning of the clamp's left and right sides, ensuring accuracy during subsequent clamp switching and movement.

[0030] In this embodiment, the fixed base 22 is equipped with multiple supporting rollers 23 and limiting rollers 24 along the moving direction of the clamp. The supporting rollers 23 and limiting rollers 24 are evenly spaced and intersecting. The moving direction of the clamp is perpendicular to the moving direction of the slide table 1. This ensures the stability of the clamp's movement as the contact between the plate and the rollers gradually decreases during the clamp's movement.

[0031] Furthermore, the mobile trolley 2 is provided with positioning pulleys 25 on both sides, and the positioning garage 3 is provided with positioning plates 31 on both sides. The positioning plates 31 are set vertically, the rotation center axis of the positioning pulleys 25 is parallel to the positioning plates 31, and the positioning pulleys 25 abut against the positioning plates 31.

[0032] By setting horizontal positioning pulleys 25 on both sides of the mobile trolley 2, which abut against the positioning plates 31 on both sides of the positioning garage 3, the left and right positions of the mobile trolley 2 are positioned. The structure is simple, and the trolley can be moved conveniently through rolling friction.

[0033] In this embodiment, as Figure 5As shown, the slide table 1 is equipped with a receiving pulley group 11 corresponding to the transfer pulley group 21. The receiving pulley group 11 and the transfer pulley group 21 have the same structure. The two ends of the clamp during the switching process are supported respectively, and both are based on rolling friction, which makes operation convenient.

[0034] Preferred implementation methods, such as Figure 2 As shown, a clamp positioning component 26 is provided at the end of the mobile trolley 2 away from the slide table 1, and an elastic protective pad 27 is fixed on the side of the clamp positioning component 26 facing the clamp. This is to position the clamp on the trolley, making it easy to fix the clamp on the trolley by fixing pins.

[0035] In this embodiment, as Figure 3 As shown, the positioning garage 3 is equipped with a trolley positioning component 32, and the mobile trolley 2 is equipped with a support beam 28. The trolley positioning component 32 is positioned at the same height as the support beam 28 and is provided with an elastic buffer pad 33 on the side facing the support beam 28.

[0036] Installing elastic protective pads 27 on the positioning components of the mobile trolley and the fixture, and installing elastic buffer pads 33 on the trolley positioning component 32 in the positioning garage, can effectively ensure soft contact during the movement and positioning of the trolley, avoid damage to the trolley or other structures, and extend the service life of the tooling.

[0037] Furthermore, a trolley fixing component 34 is provided on one side of the trolley positioning component 32. The trolley fixing component 34 includes a drive cylinder and a limiting arm. The drive cylinder drives the limiting arm, and the limiting arm abuts against the side of the support beam 28 away from the slide table 1.

[0038] The positioning garage is equipped with corresponding trolley positioning components to ensure the relative position between the trolley and the slide. At the same time, the trolley fixing components can reliably fix the trolley on the trolley positioning components, so that the clamp can move accurately onto the slide and ensure the stability of the trolley during the movement. Compared with manual switching, the positioning accuracy is higher and it is more time-saving and labor-saving.

[0039] In this embodiment, the slide table 1 is equipped with a telescopic motor that mates with the positioning mounting holes on the furniture, and the telescopic rod of the motor is vertically arranged. The positioning garage 3 includes a positioning base, which is fixed to the ground and can provide mounting and fixing for the positioning plate. The telescopic motor accurately fixes the clamp on the slide table, ensuring the stability and accuracy of subsequent welding.

[0040] Specifically, the mobile trolley consists of a pushable trolley and a loading fixture. The trolley and fixture are manually positioned and fixed by pins. The fixing device consists of a positioning garage and a sliding platform. The positioning garage is fixed to the ground with chemical bolts. In the process, the worker pushes the trolley into the storage position, removes the pin connecting the fixture and the trolley, pushes the fixture into the sliding platform, and then manually inserts the pin. The sliding platform automatically slides the fixture to the working position, where the robot performs welding. AGVs can also be used to improve automation. The above tooling can be quickly switched, is easy to operate, and can respond quickly to malfunctions on the production site. The sliding platform is driven by an electric motor, greatly reducing the overall footprint. The high-precision positioning structure allows for precise control of the fixture position, also reducing maintenance costs for the OEM.

[0041] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
