Description

Technical Field

[0001] The utility model relates to the technical field of chain connection positioning molds, in particular to a positioning mold for chain links.

Background Art

[0002] A chain generally has a metal link or ring shape, which is mainly composed of a plurality of chain links connected together, and is mainly used for mechanical movement and traction, etc. There are many types of chains, but their basic structure is mainly of this kind. For different application scenarios of the chain, scrapers, guide bearings or push plates, etc. will be installed on the chain. These are all for modifying the chain to be used in different scenarios. Some of these external accessories are fixed to the link by bolts, and some are directly welded to the chain link by welding. For example, for the chain used in a grain harvester, a push plate is welded on the chain so that it can push the grain for transmission. The existing chain link positioning mold is mainly composed of a base and a clamping block connected together. By placing the chain link on the base in advance and moving the clamping block relatively, the chain link is clamped. At this time, the operator places the external accessory on the chain link and holds a welding torch to weld the external accessory to the chain link, thereby realizing the fixation of the chain link and the external accessory.

[0003] Although the above solution can position and weld the chain link and the external accessory, there are still the following problems: First, after the chain link is positioned and clamped, the operator needs to hold the external accessory and a welding torch to fix the external accessory on the chain link. However, since a thrust will be generated during the welding of the external accessory, this thrust is likely to cause an offset between the external accessory and the chain link. Once the external accessory is offset, it is very likely to cause a significant decrease in the welding accuracy.

Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems in the prior art, and propose a positioning mold for chain links, which can reduce the offset during the welding of external accessories.

[0005] To achieve the above purpose, the utility model proposes a positioning mold for chain links, including: a base,

[0006] It further includes:

[0007] A fixed rod, the fixed rod is slidably connected to the base in a relatively driven manner;

[0008] A support seat, the support seat is slidably connected to the base in a driven manner;

[0009] A first pressing block, the first pressing block is slidably connected to the bottom surface of the support seat in a driven and lifting manner, and the first pressing block can be arranged opposite to the chain link;

[0010] A first fixing block, the first fixing block is slidably connected to the support seat in a relatively driven manner.

[0011] Preferably, a second pressing block is driven to lift and slide on the bottom surface of one side of the first pressing block, and the second pressing block can be disposed opposite to the external accessory.

[0012] Preferably, anti-scratch sponges are fixedly connected to the bottom surfaces of the first pressing block and the second pressing block, and the anti-scratch sponges are disposed opposite to the base.

[0013] Preferably, a plurality of chain positioning rods are fixedly connected to the base.

[0014] Preferably, a sprocket is rotatably connected to the chain positioning rod, and the chain is located between the sprockets.

[0016] Advantages of the present utility model: Compared with the prior art, the external accessory is pressed by the first pressing block provided on the support seat in the present utility model. After the external accessory is pressed, the first fixing block moves relatively. By using the relative movement of the first fixing block, the external accessory is clamped, so as to achieve the fixation of the external accessory. By positioning and clamping the external accessory on the link, the situation that the external accessory is offset during the welding process can be reduced, and at the same time, the situation that the external accessory scalds people due to excessive temperature during welding can also be reduced.

[0025] As Figures 1 to 2 , the present utility model discloses a positioning die for chain links, including: a base 1,

[0026] It further includes: a fixed rod 2, a support seat 3, a first pressing block 4 and a first fixing block 5;

[0027] Wherein the fixed rod 2 is driven to be slidably connected to the base 1, and is mainly used for clamping the chain link;

[0028] The support base 3 is driven to be slidably connected to the base 1. The support base 3 is mainly driven by the first electric push rod 13. The first electric push rod 13 is fixedly connected to the base 1 and one end thereof is fixedly connected to the support base 3, so that the movement of the support base 3 can be realized. When the support base 3 approaches the external accessory, the first pressing block 4 which is driven to be slidably connected to the bottom surface of the support base 3 moves. The external accessory is pressed onto the link by the first pressing block 4. It is worth mentioning that the driving mode of the first pressing block 4 is driven by the second electric push rod 14. The second electric push rod 14 is fixedly connected to the support base 3 and one end thereof is fixedly connected to the first pressing block 4, so that the movement of the first pressing block 4 can be realized. When the external accessory is pressed against the link, the first fixing block 5 which is relatively driven to be slidably connected to the support base 3 moves. The fixation of the external accessory is realized through the movement of the first fixing block 5, and the fixation effect of the external accessory is further improved. It is worth mentioning that the first fixing block 5 is driven by the third electric push rod 15. The third electric push rod 15 is fixedly connected to the support base 3 and one end thereof is fixedly connected to the first fixing block 5, so that the movement of the first fixing block 5 can be realized.

[0029] Specifically, since the bottom surface of the support base 3 on one side of the first pressing block 4 is driven to be slidably connected with a second pressing block 6, the second pressing block 6 can be arranged opposite to the external accessory. It is worth mentioning that the second pressing block 6 is driven by the fourth electric push rod 16. The fourth electric push rod 16 is fixedly connected to the support base 3 and the output shaft is fixedly connected to the second pressing block 6, so that the movement of the second pressing block 6 can be realized, and further the second pressing block 6 can fix the external accessory, and the fixation effect of the external accessory is further improved.

[0030] Specifically, anti-scratch sponges 7 are fixedly connected to the bottom surfaces of the first pressing block 4 and the second pressing block 6. The anti-scratch sponges 7 mainly prevent the first pressing block 4 and the second pressing block 6 from scratching the external accessory.

[0031] Specifically, a chain positioning rod 8 is fixedly connected to the base 1, which is mainly used for positioning the chain.

[0032] Specifically, a sprocket 9 is rotatably connected to the chain positioning rod 8. The sprocket 9 can be connected to the chain, so as to achieve the positioning of the chain.

[0033] Specifically, since a first bidirectional lead screw 10 is rotatably connected to the base 1, the first bidirectional lead screw 10 is threadedly connected to the fixing rod 2. A knob 11 is rotatably connected to the base 1. One end of the knob 11 is fixedly connected to the first bidirectional lead screw 10. The first bidirectional lead screw 10 is driven to rotate by the knob 11, and the first bidirectional lead screw 10 drives the fixing rod 2 to move, so as to realize the clamping and positioning of the chain by the fixing rod 2, and further improve the fixing effect of the fixing rod 2.

[0034] Principle of the utility model: Through the relative movement of the fixing rod 2, the chain link is clamped. After the clamping of the chain link is completed, the external accessory is placed on the chain link. At this time, the first pressing block 4 moves to press the external accessory on the chain link, and the external accessory is fixed through the relative movement of the first fixing block 5, thereby realizing the fixation of the external accessory and further improving the fixation effect of the external accessory.

[0035] The above embodiments are illustrative of the present utility model and not restrictive thereof. Any solution obtained by simply transforming the present utility model falls within the protection scope of the present utility model.
