Description

Technical Field

[0001] The utility model belongs to the technical field of crimping tooling, and particularly belongs to a crimping tooling for a motor bent water nozzle. Background Art

[0002] With the continuous development of new energy vehicle technology, the development of pure electric vehicles is getting faster and faster, and the electric drive is developing towards higher efficiency and higher speed, and thus the requirements for its cooling technology are also getting higher and higher. Most of the existing electric drive systems adopt water cooling or oil cooling solutions. With the accelerating development rhythm, the requirements for the efficiency and accuracy of prototype assembly are also increasing.

[0003] During the assembly process of the cooling water nozzle in the prototype stage, due to the special shape of the bent water nozzle, the force on it is uneven, and it cannot be placed in a natural state. It is often necessary to manually hold it for assembly, so that the bent water nozzle is prone to uneven force and skew deformation during pressing, which will further affect the quality of subsequent products. In addition to the prototype assembly process, in the actual pressing process, no special tooling is designed, and it is also necessary to manually hold the water nozzle for pre-pressing, and there are potential safety hazards to the personal safety of workers at this time.

[0004] At present, automatic pressing is also adopted, but usually there are many tooling parts in automatic pressing, the manufacturing and management costs are high, and the special tooling cannot meet the switching requirements of different models. Content of the Utility Model

[0005] To solve the drawbacks of manual assembly, as well as the problems that there are many tooling parts in the existing automatic pressing equipment, the manufacturing and management costs are high, and the special tooling cannot meet the switching requirements of different models. The utility model provides a crimping tooling to achieve the triple purposes of pressing, supporting and fixing, and moving up and down of the bent water nozzle.

[0006] The technical solution adopted by the utility model is as follows: A crimping tooling for a motor bent water nozzle, including a pair of clamping blocks for clamping the bent water nozzle. The two clamping blocks are symmetrically provided with grooves, and a cavity for accommodating the bent water nozzle is formed after assembly; the clamping blocks are configured with a locking component; the clamping blocks are configured with a supporting component.

[0007] Further, the supporting component includes a cross bar connected to the clamping block and a vertical bar connected to the cross bar, and a magnetic base is installed at the bottom of the vertical bar.

[0008] Further, the cross bar is threadedly connected to the clamping block through a threaded hole.

[0009] Further, the vertical bar is a smooth metal bar.

[0010] Further, the cross bar is connected to the vertical bar through a swivel joint.

[0011] Further, the locking assembly is a bolt-nut assembly, and multiple groups of bolt-nut assemblies are provided.

[0012] Further, the number of bolt-nut assemblies at the front side of the bent water nozzle is less than that at the rear side.

[0013] Further, the diameter of the groove opening is smaller than the diameter of the upper shoulder of the bent water nozzle.

[0014] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0015] 1. The pressing tool for the motor bent water nozzle realizes effective clamping of the bent water nozzle through profiling machining of the clamping block, solving the fixation problem of this special-shaped water nozzle. And by using the cross bar, the lateral support of the bent water nozzle is ensured. While meeting the product assembly requirements, it avoids the need for manual hand support of the bent water nozzle for pre-pressing during pressing, not only reducing the work burden of the staff, but also ensuring the personal safety of the staff. At the same time, the structure of this tool is simple, and the manufacturing and management costs are low.

[0016] 2. In a limited space, as many bolt-nut assemblies as possible are arranged on the clamping block. For the purpose of achieving force balance, bolt-nut assemblies are arranged both above and below the clamping block. However, since the volume needs to be minimized at the front part, only one group of bolt-nut assemblies is arranged separately at the front side of the water nozzle, while two groups of bolt-nut assemblies are arranged at the rear side.

[0017] 3. Through the slight sliding between the smooth vertical rod and the adapter, while fixing the bent water nozzle, a downward sliding freedom is given, ensuring the assembly quality. Description of the Drawings

[0026] The following will be combined with Figures 1 - 3 to describe the present utility model in detail.

[0027] Embodiment

[0028] As Figure 1 , Figure 2 , Figure 3 shown, a pressing tool for the bent water nozzle of a motor includes a pair of clamping blocks 2 for clamping the bent water nozzle 1. The opposite ends of the two clamping blocks 2 are profiled with grooves 8. When the grooves 8 at the opposite ends are closed, a complete cavity is formed to clamp the bent water nozzle 1 inside the cavity. When the left and right clamping blocks 2 are closed, a plane is formed at their tops. Subsequently, a pressing force can be applied to this top plane by a press and moved downward to be assembled into the machine shell. At this time, the limiting surface of the installation end of the bent water nozzle 1 is stressed, that is, the shoulder 10 is stressed. And the diameter of the groove 8 is smaller than the diameter of the shoulder 10 on the bent water nozzle 1.

[0029] Among them, the clamping block 2 is equipped with a locking assembly, which is a bolt and nut assembly 4. The bolt and nut assembly 4 is an M6 bolt and an M6 nut, which are used together. In a limited space, as many bolt and nut assemblies 4 as possible are arranged. Specifically, Figure 2 As shown, bolt and nut assemblies 4 are installed on both the top and bottom of the clamping block 2 to achieve the purpose of force balance. However, in order to reduce the weight of the front part of the water bend 1, only one set of bolt and nut assemblies 4 is retained at the bottom of the front part, while bolt and nut assemblies 4 are arranged on the top and bottom of the rear part.

[0030] The clamping block 2 is equipped with a support assembly, which includes a crossbar 3 connected to the clamping block 2 and a vertical rod 6 connected to the crossbar 3. A magnetic base 7 is installed at the bottom of the vertical rod 6. Any one of the two clamping blocks 2 is provided with a threaded hole 9, through which the crossbar 3 for lateral support of the clamping assembly is connected. Figure 2 As shown, the threaded hole 9 is set on the right clamping block 2, and the cross bar 3 is used to simulate human hands to provide lateral support to the clamping block 2 and the bend water spout 1, avoiding the need for manual hand-held pre-pressing of the bend water spout 1 during press-fitting, thereby reducing the workload of the staff and reducing safety hazards.

[0031] like Figure 1 As shown, the end of the crossbar 3 is fitted with an adapter 5, made of plastic. This adapter 5 connects the horizontal crossbar 3 to the vertically positioned upright pole 6, which is made of metal and has a relatively smooth surface. When applied, the adapter 5 can slide slightly along the upright pole 6. A magnetic base 7 is mounted on the end of the upright pole 6. The metal upright pole 6 and the magnetic base 7 utilize magnetic principles to secure and support the fixture, providing stable support.

[0032] It is worth noting that, in the actual assembly process, there is a housing under the bend faucet 1 to which the faucet needs to be crimped, which supports the bend faucet 1. Therefore, there is no need to worry about the adapter 5 moving downward along the vertical rod 6 under the influence of gravity.

[0033] This tool is made of 45# steel, a common tool material, so the processing and manufacturing cost is low. In addition, the sharp edges of this tool are chamfered on all sides, which is safe and reliable.

[0034] During implementation, it's worth noting that this crimping tool isn't limited to crimping bend faucets; it can also be used with straight faucets. However, in this case, the diameter of the groove 8 in the clamping block 2 is smaller than the diameter of the shoulder 10 in the straight faucet, and the length of the straight faucet within the groove 8 is less than its depth. The shoulder 10 acts as a stop, preventing the straight faucet from moving upward during downward press-fit.

[0035] Specifically, when using this press-fitting tooling for the motor bent water nozzle, first, the opposite ends of the two clamping blocks 2 are shaped into semi-circular grooves 8 by profiling. Then, the bent water nozzle 1 is placed in the groove 8 of the left clamping block 2, and three M6 bolts are correspondingly inserted into the through holes of the left clamping block 2. At this time, the right clamping block 2 is placed, and the three M6 bolts correspondingly pass through the through holes of the right clamping block 2. Subsequently, the three M6 nuts are tightened. At this time, the bent water nozzle 1 is clamped in the cavity formed by the cooperation of the grooves 8 of the left and right clamping blocks 2, and a complete plane is formed at the top of the left and right clamping blocks 2.

[0036] The cross bar 3 is installed in the threaded hole 9 of the right clamping block 2 for lateral support. Then, the cross bar 3 is inserted into the adapter 5, and the adapter 5 is installed on the vertical rod 6. After assembly, a press can be used to press-fit the top plane of the left and right clamping blocks 2. When the bent water nozzle 1 is pressed down, the cross bar 3 with the adapter 5 can move downward correspondingly on the vertical rod 6, so as to achieve the triple purposes of press-fitting, supporting and fixing, and moving up and down of the bent water nozzle 1.

[0037] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
