Description

Technical Field

[0001] The utility model relates to the technical field of industrial production, in particular to a tooling mechanism. Background Art

[0002] In industrial production, in order to achieve the maximum compatibility function of the processing floor production line, a production line often needs to produce multiple types of products. In this process, it is necessary to change the tooling on the production line. In the welding production of electric bicycle frames, due to the large variety of new products produced every year, the production line changes products of different types according to orders every day. Therefore, different types of tooling need to be replaced. However, currently, after the tooling is changed, bolts are generally used to fasten the tooling. Frequent use of bolts for fastening during tooling change results in serious wear of the threads on the bottom tooling fixing plate. It is often necessary to cut off the original tooling fixing plate and replace it, consuming costs. Moreover, the bolts need to be screwed in and out, consuming a lot of time.

[0003] Patent CN 212946624 U discloses a tooling rapid change mechanism, which uses wing bolts with semi-circular pressing blocks to fix the tooling and the floor. However, only when the thickness of the replaced tooling is the same can it be ensured that when the wing bolts are turned, only the semi-circular pressing blocks rotate. In actual situations, the thicknesses of different toolings are not exactly the same. Therefore, during installation, the screwing depth of the wing bolts also needs to be continuously adjusted to adapt to toolings of different thicknesses. It can be seen that it also needs to adjust the screwing depth of the bolts into the bolt holes, which will also cause wear of the bolt holes on the floor. Similarly, repeatedly adjusting the screwing height of the bolts to clamp the tooling also consumes a lot of time.

[0004] Therefore, a tooling mechanism is needed that can quickly lock and unlock the tooling main body and is beneficial for long-term use. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0025] The purpose of the present utility model is to provide a tooling mechanism to solve the problems existing in the prior art, which can quickly lock and unlock the main body of the tooling and is beneficial for long-term use.

[0026] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] As Figures 1 - 3 shown, the present utility model provides a tooling mechanism, which includes a tooling main body 1 and a base. The base is used to fix the tooling main body 1. The base includes a lifting mechanism 6, a pressing plate 5, and a support seat. The support seat is arranged below the pressing plate 5. The lifting mechanism 6 is connected to the pressing plate 5 and is used to drive the pressing plate 5 to rise or fall. The lifting mechanism 6 is arranged close to the support seat and is located at the edge of the tooling main body 1. Driving the pressing plate 5 to rise or fall by the lifting mechanism 6 can unlock or lock the tooling main body 1 relative to the support seat. Using the lifting mechanism 6 to drive the pressing plate 5 to realize the pressing or loosening of the tooling main body 1 saves a lot of time compared with repeatedly screwing bolts. Roughly calculated, the fastening time can be reduced from the original 210 seconds to about 15 seconds, which can quickly lock and unlock the tooling main body 1, greatly improving the tool change fastening efficiency. And compared with bolts, there is no need to repeatedly screw, avoiding the wear of bolts and screw holes, which is beneficial for long-term use.

[0028] In this embodiment, a positioning guide sleeve 2 is arranged on the tooling main body 1. The base also includes a positioning pin. The positioning pin is arranged on the support seat and is used to extend into the positioning guide sleeve 2 to realize the positioning of the tooling main body 1 when installed on the base. Among them, there is a gap of 0.06 - 0.08 mm, preferably 0.08 mm, between the positioning pin and the guide sleeve 2 to prevent the positioning pin from jamming the tooling main body 1. The positioning pin is a standard part. Grooves and four bolt holes are machined on the support seat for fixing the positioning pin on the support seat. The cooperation of the positioning pin and the guide sleeve 2 realizes precise positioning. The cooperation gap between the two parts is 0.08 mm, which can largely realize the precise positioning of the tooling main body 1 and will not cause over-positioning resulting in the jamming of the tooling main body 1 and the positioning pin.

[0029] In this embodiment, the positioning pin includes a diamond-shaped positioning pin 11 and a circular positioning pin 9 arranged diagonally. The circular positioning pin 9 is used for the preliminary positioning of the tooling main body 1, and the diamond-shaped positioning pin 11 is used to fix the tooling main body 1 to prevent the tooling main body 1 from rotating. When installing the tooling main body 1, first roughly position it with the circular positioning pin 9, and then align the guide sleeve 2 with the diamond-shaped positioning pin 11 to realize the precise positioning and anti-rotation of the tooling main body 1. It should be noted that the positioning pins can also be set to other numbers, for example, arranged in the diagonal direction of the tooling main body 1, with a total of two. The positioning pins can also all be circular positioning pins 9 or diamond-shaped positioning pins 11 or any combination of circular positioning pins 9 and diamond-shaped positioning pins 11.

[0030] In this embodiment, the support base includes a support frame 3 and a fixed base 4. The support frame 3 is used to support the tooling main body 1, and the fixed base 4 is used to fix the positioning pins. The support frame 3 is set as a cylinder and there are four of them, which are respectively arranged at the positions near the four corners of the tooling main body 1. The fixed base 4 is determined according to the number of positioning pins. When two positioning pins are set, only two fixed bases 4 need to be set. The support frame 3 plays a main supporting role, but the supporting effect of this method is not as stable as that of setting at the four corners. When four positioning pins are set, four fixed bases 4 are required, and the fixed bases 4 are arranged adjacent to the support frame 3 and are arranged at the four corners of the tooling main body 1.

[0031] In this embodiment, the base further includes a limit baffle 7. The limit baffle 7 is fixedly connected to the fixed base 4 and extends out of the edge of the tooling main body 1, and is used to limit the tooling main body 1. And a slope is provided on the side of the limit baffle 7 close to the tooling main body 1, and it gradually becomes wider from top to bottom, which can guide the installation of the tooling main body 1. The limit baffle 7 is used for the hoisting limit of the tooling main body 1 and to prevent the tooling main body 1 from pressing on the lifting mechanism 6. When the tooling main body 1 sways during hoisting and falling, the limit block is processed into a slope to facilitate the auxiliary guiding of the tooling main body 1. There is one limit baffle 7 at the upper left corner and the lower right corner of the tooling main body 1 respectively. When installing the tooling, it can approach and then fall and install.

[0032] In this embodiment, the lifting mechanism 6 is a lifting cylinder, and it is fixed on the cylinder support plate 8, and the pressing plate 5 is rotatably connected to the air rod of the lifting cylinder. When installing the tooling main body 1, first rotate the pressing plate 5 so that the pressing plate 5 leaves the path of the falling tooling main body 1. When the tooling main body 1 falls onto the support base, rotate the pressing plate 5 back to the position above the support base and lower it to press the tooling main body 1 tightly.

[0033] In this embodiment, the tooling main body 1 includes a tooling part 101 and a lifting lug 102. The lifting lug 102 is arranged on the tooling part 101 for the hoisting of the tooling part 101. In order to ensure the balance of the tooling main body 1 during hoisting, the lifting lugs 102 are arranged at the four corners of the tooling main body 1.

[0034] In this embodiment, the tooling main body 1 further includes a tooling detection column 10. A cross-shaped groove is provided at the top of the tooling detection column 10. The width of each side of the cross-shaped groove is 2 - 3 mm, preferably 2 mm. The cross-shaped groove is used for the welding torch to pass through and can detect the welding effect. When the welding torch passes through the cross-shaped groove without contact, the welding is not deviated. When the welding torch contacts the side wall of the cross-shaped groove when passing through, the welding is deviated and the position of the welding torch needs to be adjusted. This way of quick verification can avoid using the entire welding procedure to verify the welded product as a whole, saving time.

[0035] In this embodiment, the tooling main body 1 further includes a distinguishing member 103 which is arranged on the tooling part 101 and is used to distinguish different tooling parts 101. The distinguishing member 103 can be set as a nameplate, and different tooling main bodies 1 are assembled with different nameplates for easy distinction.

[0036] In the present utility model, specific examples are used to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
