[0001] The utility model belongs to the technical field of tool bit processing, specifically relates to an assembling auxiliary tool of tool bit assembly. BACKGROUND

[0002] As Figure 1 The tool bit assembly 1' includes a fixed cutter 10', a fixed cutter seat 11', a movable cutter seat 12', a movable cutter 13' and a spring 14'. The bottom of the fixed cutter seat 11' forms two edge support parts 110' and two middle support parts 111'. The first gap h1' is formed between the edge support part 110' and the middle support part 111'. The second gap h2' is formed between the two middle support parts 111'. The lower part of the movable cutter seat 12' penetrates through the second gap h2' and is connected with the power output shaft. The movable cutter 13' and the fixed cutter 10' form shearing during the reciprocating movement of the movable cutter seat 12'.

The upper end of the spring 14' is installed on the positioning column of the movable cutter seat 12'. The lower end of the spring 14' is installed on the positioning pin m' in the middle support part 111'.

[0003] However, in the actual assembly, the following technical defects exist:

[0004] 1) Since the above components are relatively scattered, they can only be assembled in batches during the assembly process. Therefore, the assembly efficiency is extremely low, and the probability of missing components often occurs.

[0005] 2) The assembly position accuracy cannot be guaranteed, which affects the relative movement and shearing quality of the movable cutter and the fixed cutter (the shearing quality is directly proportional to the user's feeling). CONTENT OF THE UTILITY MODEL

[0006] The utility model solves the technical problems of overcoming the deficiencies of the prior art and providing a new assembling auxiliary tool of tool bit assembly.

[0007] To solve the above technical problems, the utility model adopts the following technical scheme:

[0008] The assembly auxiliary tool of the tool head assembly comprises a positioning platform, a frame base and a positioning base fixed on the positioning platform, a sliding rail with end limiting blocks, a first clamping base and a second clamping base oppositely sliding on the sliding rail and oppositely moving between the two end limiting blocks, a tensioning die set between the two first clamping base and the second clamping base, a tension spring for keeping the first clamping base and the second clamping base from oppositely moving, a pressing die set matched with the frame base, a lifting movable platform on the positioning platform, and a positioning pin installed on the lifting movable platform, wherein the first clamping base and the second clamping base each have two clamping heads, the fixed tool base of the tool head assembly is arranged on the positioning platform and the frame base from two ends and a bottom, the movable tool base is exposed from the second aperture, the movable cutter is fixed and slid on the fixed tool base, the spring is installed on the positioning column of the movable tool base from one end, and the lower end of the spring abuts against the fixed tool base, the fixed cutter is matched with the movable cutter and is assembled with the end of the movable tool base, and in the external support of the tensioning die set, the first clamping base and the second clamping base are oppositely supported to make the clamping heads respectively extend into the first aperture and the second aperture to clamp the movable tool base and the fixed tool base, and based on the pressing of the pressing die set, the fixed cutter and the fixed tool base are kept from being pressed and matched from the end, and based on the lifting of the lifting movable platform, the positioning pin is inserted into the fixed tool base and the lower end of the spring, so that the end welding and assembly can be implemented.

[0009] Preferably, the positioning base matches with the external connection part of the movable tool base in a column shape. The positioning of the movable tool base is facilitated.

[0010] According to a specific implementation and preferred aspect of the utility model, the clamping head in the second aperture is based on the positioning base and is inserted into the movable tool base from the positioning base, and the clamping head is clamped on the opposite two sides. Under the limitation of the reference, the relative clamping is further used to ensure the position of the movable cutter, thereby facilitating the accurate assembly of the positioning pin.

[0011] Preferably, the first clamping base comprises a first base body, a first U-shaped clamping arm formed at the end of the first base body, a first clamping head and a second clamping head formed at the end of the first U-shaped clamping arm; the second clamping base comprises a second base body, a second U-shaped clamping arm formed at the end of the second base body, a third clamping head and a fourth clamping head formed at the end of the second U-shaped clamping arm, wherein the first U-shaped clamping arm and the second U-shaped clamping arm are staggered and oppositely slid, and the two staggered clamping arms are located in the second aperture, and the other clamping arms are respectively located in the corresponding first aperture, the first clamping head and the fourth clamping head are respectively located in the first aperture at two ends, and the second clamping head and the third clamping head are located in the second aperture.

[0012] Preferably, the first U-shaped clamping arm and the second U-shaped clamping arm are slid in the up-down direction.

[0013] In some embodiments, when the tensioning module resets, the second chuck and the third chuck located in the second gap are separated from the moving knife holder, and the first chuck and the third chuck and the second chuck and the fourth chuck are respectively clamped on the opposite sides of the two middle supporting parts of the fixed knife holder.

[0014] Further, when the tensioning module resets, the first chuck and the third chuck are clamped on the opposite sides of the lifting moving platform, and the second chuck and the fourth chuck are clamped on the opposite sides of the other lifting moving platform. That is, no matter in the outward supporting state or the inward retracting state, the formed chucks are clamped on the moving knife holder and the fixed knife holder or clamped on the opposite sides of the lifting moving platform.

[0015] According to another specific implementation and preferred aspect of the utility model, the lower pressing module comprises a lower pressing module assembled with the frame seat, and a pressing column installed inside the lower pressing module and capable of abutting against the surface of the fixed knife. Based on the accurate positioning of the end part by the lower pressing positioning, the pressing column can correct the fixed knife, thereby improving the fitting degree of the fixed knife and the moving knife.

[0018] Further, the lifting moving platform is a disc body movably installed on the positioning platform, and the positioning pin is vertically installed on the disc body. In the positioning pin positioning assembly, the disc body is upwardly lifted to insert the positioning pin into the lower end of the fixed knife seat and the spring.

[0019] Due to the implementation of the above technical scheme, the utility model has the following advantages compared with the prior art:

[0020] In existing cutter head assembly processes, the components are relatively scattered, requiring assembly in stages, resulting in extremely low assembly efficiency and a high probability of missing components. Furthermore, the accuracy of assembly positions cannot be guaranteed, affecting the relative movement and shearing quality of the moving and fixed blades (shearing quality is directly proportional to the user's perception). This invention addresses these shortcomings by comprehensively designing the structure of the cutter head assembly assembly aid, cleverly resolving these deficiencies. Using this aid, the fixed blade holder is mounted on a positioning platform and support from both ends and the bottom. The moving blade holder is exposed through a second notch. The moving blade is fixed to and slides on the fixed blade holder. A spring is mounted on a positioning post of the moving blade holder from one end, with its lower end abutting against the fixed blade holder. The fixed blade is aligned with the moving blade and aligned with the end of the moving blade holder from its end. In the external support of the tensioning module, the first and second clamps are relatively open to allow… The chucks extend into the first and second notches respectively to clamp and position the moving and fixed blade holders. Based on the downward pressure of the pressing module, the fixed blade and fixed blade holder are kept in end-to-end matching and pressing. Based on the lifting of the lifting platform, the positioning pin is inserted into the lower end of the fixed blade holder and the spring, thus enabling end welding and component assembly. Therefore, this invention, on the one hand, uses the frame, positioning base, chucks, and clamping to sequentially position and align the various components of the blade assembly. Then, based on the lifting platform, the positioning pin is inserted into the lower part of the fixed blade holder and the spring, thereby completing the entire assembly of the component and providing assistance for end welding. Therefore, it not only reduces assembly difficulty and improves assembly accuracy but also significantly reduces the probability of missing components. On the other hand, the assembly operation is convenient; only the tensioning module needs to be rotated for clamping and positioning or loosening and disengaging. Furthermore, it can maintain the spring in a free state for alignment assembly, thereby reducing the spring's deformation rate and improving the relative motion shearing quality of the moving and fixed blades.
