[0002] With the rapid development of electric vehicles, DC motors, as the "heart" of electric vehicles - drive motors, have gradually replaced traditional fuel engines and become the protagonist in the automotive supply chain. DC motors, especially permanent magnet synchronous DC motors, have been widely used in the field of electric vehicles due to their small size, light weight, high power density and torque density.
[0003] The rotor structure of DC motors is diverse, including the traditional inner rotor structure and new structures such as disc structure, outer rotor structure and linear structure that have appeared in recent years. Among them, the demand for motor magnet rotors is also increasing. During the processing of motor magnet rotors, machines are needed to clamp them.
[0004] Traditional machines only have two top cones for locking the workpiece. During mass production, the product may be scrapped due to problems such as the top cone being in the wrong position during clamping or errors in clamping, which wastes time and manpower. Therefore, a tooling for machine tool processing of automotive components is proposed. Utility Model Content
[0005] The purpose of the utility model is to provide a tooling used for machining automobile components, so as to solve the problems raised in the above-mentioned background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tooling used for machine tool processing of automobile components, including a product, a positioning member and a limit member arranged on both sides of the product, the positioning member being detachably assembled on the end of a machine tool top cone, the positioning member comprising a first kit and a second kit, the inner wall of the first kit being formed with a first cavity adapted to the end of the machine tool top cone, and the second kit being provided with a guide groove connected to the first cavity, and being configured so that when the product shaft end is placed in the guide groove and the machine tool top cone is released, it will automatically push to the center hole of the shaft end.
[0007] As a further solution of the utility model: the product includes an injection molded part, and two end surfaces of the injection molded part are respectively provided with a positioning shaft and a magnet, and the magnet is installed with a limiting shaft away from the end surface of the injection molded part.
[0008] As a further solution of the utility model: the first cavity includes a guide cavity and a tapered cavity, the guide cavity and the tapered cavity are connected to each other, and the guide cavity and the tapered cavity respectively pass through two end surfaces of the first kit.
[0009] As a further solution of the utility model: the center of the conical cavity away from the end face of the guide cavity is a, and the cross-section of the guide groove is a semicircle, and the center of the semicircle is b, and a and b are on the same axis.
[0010] As a further solution of the utility model: the limit member includes a magnetic suction sleeve, a driving rod installed on the outer side wall of the magnetic suction sleeve, and a second cavity is formed inside the magnetic suction sleeve.
[0011] As a further solution of the utility model: the second cavity includes a through hole, a limiting hole and a guide hole that penetrate each other, and the limiting hole and the guide hole are respectively located on both sides of the through hole.
[0012] As a further solution of the utility model: the limiting hole is adapted to the magnet, the through hole is adapted to the limiting shaft, and the guide hole is adapted to the end of the top cone of the external cylindrical grinding clamp.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. Through the setting of the first set and the second set, and under the action of the guide cavity, the conical cavity and the guide groove, the rapid positioning and guiding between the product and the machine tool top cone is realized, which greatly saves the consumption of eyesight at work and avoids the need for employees to align the product and the machine tool top cone by themselves when positioning. This process is prone to problems such as the misposition of the machine tool top cone or dizzy clamping errors.
[0015] 2. By setting the interior of the magnetic sleeve to a shape and size that matches the magnet and the limit shaft, the end of the product can be fixed by simply inserting it into the interior of the magnetic sleeve. The fixing effect is good, which greatly reduces the rework rate and improves efficiency. It avoids the need to find a suitable angle when clamping the product, which takes about 5 seconds each time. If the clamping angle is slightly offset, the product cannot be clamped, which affects the external cylindrical grinding effect. The product needs to be reworked, which increases the workload.

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments 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 in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figure 1-6 In an embodiment of the utility model, a tooling used for machine tool processing of automobile components includes a product 1, positioning parts and limit parts arranged on both sides of the product 1, the positioning parts are detachably assembled on the end of the machine tool top cone, the positioning parts include a first kit 2 and a second kit 3, the inner wall of the first kit 2 is formed with a first cavity 21 adapted to the end of the machine tool top cone, and the second kit 3 is provided with a guide groove 31 connected to the first cavity 21, and is configured to place the axial end of the product 1 in the guide groove 31 and then release the machine tool top cone so that it will automatically push to the center hole of the axial end.
[0025] Specifically, product 1 is arranged between the positioning part and the limiting part, so as to complete the clamping of product 1. Secondly, the positioning part, the limiting part and product 1 are all movably connected, so as to be convenient for replacement according to the model of product 1. At the same time, the interior of the first cavity 21 of the first kit 2 is always adapted to the top cone of the machine tool, so as to facilitate the subsequent unified processing and assembly of the tooling, without the need to replace the top cone of the machine tool simultaneously. The tooling can also be used for the external cylindrical grinding of all shaft products. We can match the guide groove 31 according to the shaft diameter of product 1, and the inner diameter of the first cavity 21 can be synchronously matched with the outer diameter and taper of the top cone of the machine tool used to process the product, and the tooling material can also be changed according to the weight and process requirements of the processed product 1.
[0026] See also Figure 4 In one embodiment, in this embodiment, preferably, the product 1 includes an injection molded part 11, and two end surfaces of the injection molded part 11 are respectively provided with a positioning shaft 12 and a magnet 13, and the magnet 13 is installed with a limiting shaft 14 away from the end surface of the injection molded part 11.
[0027] See also Figure 5 In one embodiment, in this embodiment, preferably, the first cavity 21 includes a guide cavity 211 and a conical cavity 212, the guide cavity 211 and the conical cavity 212 are interconnected, and the guide cavity 211 and the conical cavity 212 respectively pass through the two end surfaces of the first kit 2.
[0028] Specifically, the machine tool top cone includes an integrally arranged columnar structure and a conical structure, the outer wall of the columnar structure is adapted to the inner wall of the guide cavity 211, and the outer wall of the conical structure is adapted to the inner wall of the conical cavity 212. When the first kit 2 is completely mounted on the machine tool top cone, the sharp end of the conical structure passes through the first kit 2, which is convenient for subsequent alignment with the center of the end face of the positioning shaft 12, thereby achieving a good limiting effect.
[0029] See also Figure 4-5 In one embodiment, in this embodiment, preferably, the center of the conical cavity 212 away from the end face of the guide cavity 211 is a, and the cross-section of the guide groove 31 is a semicircle, and the center of the semicircle is b, and the center a and the center b are on the same axis.
[0030] Specifically, when the positioning shaft 12 is matched with the guide groove 31, the center of the semicircle is b, which is the center of the end face of the positioning shaft 12. At this time, the positioning shaft 12 is inserted along the axis of the guide groove 31, so that the center of the positioning shaft 12 can be completely aligned with the sharp end of the machine tool top cone and locked, avoiding the phenomenon of the top cone being misplaced or the clamping error. The staff does not need to spend time to align the center of the circle, thereby achieving the effect of saving the overall clamping time.
[0031] See also Figure 3 In one embodiment, in this embodiment, preferably, the limiting member includes a magnetic sleeve 4, a driving rod 5 installed on the outer wall of the magnetic sleeve 4, and a second cavity 41 is formed inside the magnetic sleeve 4; the second cavity 41 includes a through hole 411, a limiting hole 412 and a guide hole 413 that are interconnected, the limiting hole 412 and the guide hole 413 are respectively located on both sides of the through hole 411, the limiting hole 412 is adapted to the magnet 13, and the through hole 411 is adapted to the limiting shaft 14, the guide hole 413 is adapted to the end of the top cone of the outer cylindrical grinding clamp, and the guide hole 413 is specifically conical, and the port diameter adjacent to the top cone of the outer cylindrical grinding clamp is larger than the port diameter on the other side, so as to facilitate better alignment of the end of the product 1 during the clamping process.
[0032] Specifically, the inner wall of the limiting hole 412 is provided with a layer of magnetic material. When the magnet 13 enters into the limiting hole 412, the position of the magnet 13 can be adsorbed and fixed to ensure that the product 1 and the limiting member will not easily move axially. Secondly, the limiting hole 412 is a polygonal structure, and the shape of the limiting hole 412 is the same as the shape of the magnet 13. In this embodiment, preferably, the shape of the limiting hole 412 is a quadrilateral, which can effectively avoid axial rotation between the product 1 and the limiting member. With the synchronous combination of the shape of the limiting hole 412 and the magnetic material, the limiting shaft 14 can be fixed in the second cavity 41. The product 1 has a good fixing effect, which greatly reduces the rework rate, and it only takes 1-2S to place the product each time, which also improves efficiency.
[0033] The working principle and use process of the utility model are as follows: first, the corresponding positioning parts and limiting parts are selected according to the model and size of the product 1, and then the positioning parts are fixed on the top cone of the machine tool, and then the positioning shaft 12 is placed at the end of the product 1 along the length direction of the guide groove 31, so that the center of the end face of the positioning shaft 12 can be quickly aligned with the end of the top cone of the machine tool, and then the limiting shaft 14 is inserted into the second cavity 41, and is fixed to the other end of the product 1 under the action of the limiting hole 412 and the magnet 13, and then the external cylindrical grinding clamp top cone is quickly aligned with the center of the end face of the limiting shaft 14 under the action of the guide hole 413, so that the whole clamping process of the product 1 saves a certain amount of time, and the alignment and clamping accuracy of the product 1 is high.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
