DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0024] like Figures 2 to 5 As shown, a bow head support assembly tool includes a workbench 1. The length direction of the bow head is the longitudinal direction of the workbench 1, and the width direction roughly perpendicular to the length direction of the bow head is the transverse direction of the workbench 1. For example, two support seats 2 are arranged opposite to each other in the longitudinal direction on the end surface of the workbench 1, and the two support seats 2 are used to support the two balance seats 18 of the bow head respectively, so as to support the bow head on the workbench 1 as a whole. In detail, the support seat 2 includes two first support platforms 3 opposite to each other in the transverse direction and a second support platform 4 located between the two first support platforms 3. It can be understood that the two first support platforms 3 can support the two sides of the balance seat 18 in the transverse direction, and the second support platform 4 can support the connecting seat 20 at the bottom of the balance seat 18, so the support height of the second support platform 4 is configured to be lower than the height of the first support platform 3. In more detail, a positioning hole 5 is opened on the end surface of the first support platform 3, for example, fasteners such as bolts can be passed through the assembly holes on both sides of the balance seat 18 to press and position the balance seat 18 on the positioning hole 5. Preferably, a positioning boss 16 is provided on the top of the second support platform 4 , and the positioning boss 16 is adapted to the connection groove 21 on the connection seat 20 to achieve support for the maximum fitting area of ​​the connection seat 20 .

[0025] In addition, two clamping assemblies 6 are disposed opposite to each other on both sides of the support seat 2 on the end surface of the workbench 1. For example, the clamping assembly 6 may include two third support platforms 7 disposed opposite to each other in the transverse direction, and a clamping member 8 is disposed on the third support platform 7. When the bow head is clamped and assembled, the ram horn 19 of the bow head can be inserted into the balance seat 18, and then the end of the ram horn 19 away from the balance seat 18 is supported in the third support platform 7, and the clamping member 8 can press the end against the third support platform 7, thereby achieving stable clamping between the ram horn 19 and the balance seat 18.

[0026] In some embodiments, a support groove 9 matching the structure of the ram's horn 19 is provided on the third support platform 7, so that the end of the ram's horn 19 can be stably embedded in the support groove 9. The abutting member 8 can preferably be a push-pull clamp arranged on the side wall of the third support platform 7, and the end of the ram's horn 19 can be pressed into the support groove 9 by the clamping force of the clamp, thereby achieving a more stable clamping effect.

[0027] In order to ensure the positioning accuracy between the horn 19 and the balance seat 18, the workbench 1 is provided with a first mounting hole group 10 for positioning and installing the third support platform 7. For example, the first mounting hole group 10 preferably includes two mounting holes 14 opposed to each other in the longitudinal direction and a positioning pin hole 15 located between the two mounting holes 14. When the third support platform 7 is installed, it can be pressed and set on the two mounting holes 14 by fasteners, and a positioning pin can be arranged between the third support platform 7 and the corresponding positioning pin hole 15 to ensure the position accuracy between the third support platform 7 and the balance seat 18.

[0028] Preferably, the workbench 1 is also provided with a second mounting hole group 11, which preferably has the same structure as the first mounting hole group 10, and only needs to be able to meet the positioning and installation requirements of the third support platform 7. The special point is that the second mounting hole group 11 is spaced apart from the first mounting hole group 10 in the longitudinal direction. Therefore, the third support platform 7 can be arranged on the second mounting hole group 11, and thereby the positioning support of the horns 19 of different lengths can be achieved.

[0029] For example, the workbench 1 is also provided with a mounting platform 12, and the above-mentioned first support platform 3 and second support platform 4 are sequentially arranged on the mounting platform 12 in the horizontal direction, and three third mounting hole groups 13 are also correspondingly arranged on the mounting platform 12. Among them, the third mounting hole group 13 and the first mounting hole group may also preferably have the same structure, the difference being that the mounting holes 14 and the positioning pin holes 15 of the third mounting hole group 13 are arranged in the horizontal direction. It can be understood that by limiting the positions of the three positioning pins of the three third mounting hole groups 13, the installation positions of the second support platform 4 and the two first support platforms 3 can be limited, so that the balance seat 18 supported on the support seat 2 is not prone to tilting and other poor precision.

[0030] In some embodiments, the workbench 1 is further provided with a positioning auxiliary hole, which is opposite to the positioning pin hole 15 of the third mounting hole group 13. For example, Figure 5 The embodiment in which the positioning auxiliary hole is opposite to the third mounting hole group 13 in the middle is shown. Therefore, during the assembly process of the second support platform 4, the positioning pins corresponding to the second support platform 4 can simultaneously pass through the mounting platform 12 and the workbench 1 to achieve double positioning, thereby achieving a better positioning effect of the support seat 2.

[0031] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
