Abstract
Description
Technical Field
[0001] This utility model belongs to the field of motor manufacturing technology, specifically relating to an auxiliary tooling for cutting and stripping enameled wires from motor stators at fixed intervals. Background Technology
[0002] In the manufacturing of automotive air conditioning compressor motors, the processing quality of the stator phase wires can affect the motor's performance. Currently, the stripping of stator phase wires mainly relies on operators manually placing the phase wires into the stripping machine. This manual operation method has many drawbacks: firstly, the stripping length depends entirely on the operator's manual control, making the process labor-intensive and time-consuming; secondly, due to the lack of precise length control methods, it is difficult to guarantee consistent stripping length (a certain degree of error is permissible), resulting in unstable stripping quality, which can easily lead to a decline in motor performance and create potential quality problems.
[0003] Meanwhile, the three stator phase wires on existing motors are usually of different lengths before being cut. Therefore, to ensure the quality of the motor stator, the three stator phase wires usually need to be cut to a uniform length before the enamel stripping operation. However, cutting the stator phase wires requires operators to use a ruler to measure the length of the lead wires, which is not only time-consuming and labor-intensive, but also prone to errors due to human measurement and operation. If an error is made, the entire stator will have to be scrapped, greatly increasing production costs and having a serious adverse impact on actual production.
[0004] Therefore, there is an urgent need for an auxiliary tooling that can achieve fixed-distance cutting of stator phase wires and fixed-distance control of paint stripping length, so as to improve the quality and efficiency of automotive air conditioning compressor motor production. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an auxiliary tooling for cutting and stripping the enameled wire of the motor stator at a fixed distance, which solves the problems of inconvenience in cutting and stripping the enameled wire of the stator and inconsistent residual length in the prior art.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an auxiliary tooling for cutting and stripping enameled wire at a fixed distance on motor stator, including a tooling base plate and a pressure plate support and a cutting support plate disposed on the tooling base plate;
[0007] The tooling base plate is provided with a positioning groove for movably embedding and positioning the motor stator, and the side wall of the positioning groove is provided with a positioning key that can engage with the motor stator.
[0008] A wire clamp is detachably connected to the pressure plate support base. The wire clamp includes a first clamping block and a second clamping block hinged to the first clamping block. The stator enameled wire can be clamped and fixed between the first clamping block and the second clamping block.
[0009] The top side of the cutting support is provided with three second limiting grooves for movably embedding the enameled wire, and a cutting blade that can form a shearing force with the edge of the second limiting groove is hinged on the cutting support.
[0010] Optionally, the first clamping block and the second clamping block are provided with a first limiting groove for the stator enameled wire to pass through, and a silicone pad is provided in the first limiting groove.
[0011] Optionally, the pressure plate support includes a plurality of short support rods detachably connected to the tooling base plate and a support block detachably connected to the top of the plurality of short support rods.
[0012] Optionally, the top side of the support block is provided with a contoured groove for movably embedding the first clamping block or the second clamping block.
[0013] Optionally, the bottom side of the contoured groove can be magnetically connected to the first clamping block or the second clamping block via a first magnet.
[0014] Optionally, when the first clamping block and the second clamping block clamp the stator enameled wire, the first clamping block and the second clamping block can be magnetically connected by a second magnet.
[0015] Optionally, the cutting blade is provided with a handle, and the handle is provided with anti-slip texture.
[0016] Optionally, the cutting support includes multiple long support rods detachably connected to the tooling base plate and a dividing block detachably connected to the top of the multiple long support rods, and the second limiting groove is disposed on the top side of the dividing block, and the cutting blade is hinged to one end of the dividing block.
[0017] Compared with existing technologies, the beneficial effects achieved by this utility model are as follows: Through the coordinated operation of components such as the positioning groove, wire clamp, and cutting blade, efficient and precise processing of the phase wires of the motor stator enameled wire is realized. Operators can easily position the motor stator, straighten and fix the phase wires in the stator enameled wire, and complete the fixed-distance cutting to ensure that the lengths of the three phase wire bundles are consistent. Simultaneously, the wire clamp serves as a reference for stripping the enameled wires, ensuring uniform stripping lengths. This tooling significantly reduces human error, decreases labor intensity, improves the quality and efficiency of motor stator phase wire processing, and effectively avoids motor performance problems and stator scrapping risks caused by poor phase wire processing.

These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0025] It should be noted that if directional indicators (such as up, down, bottom, top, etc.) are involved in this embodiment, these directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances. Example 1
[0026] like Figures 1-4As shown, an auxiliary tooling for cutting and stripping enameled wire from a motor stator at a fixed distance includes a tooling base plate 1 and a pressure plate support and a cutting support mounted on the tooling base plate 1. The tooling base plate 1 has a positioning groove 101 for movably embedding and positioning a motor stator 2, and the side wall of the positioning groove 101 has a positioning key 3 that can engage with the motor stator 2. The positioning key 3 can engage with a slot at a fixed position on the motor stator 2, thereby ensuring the uniqueness of the motor stator 2's position within the positioning groove 101. A wire clamp is detachably connected to the pressure plate support. Specifically, the wire clamp includes a first clamping block 4 and a second clamping block 5 hinged to the first clamping block 4. The stator enameled wire 201 (phase wire) can be clamped and fixed between the first clamping block 4 and the second clamping block 5. Simultaneously, the first clamping block 4 and the pressure plate support, and the second clamping block 5 and the pressure plate support, can be easily disassembled and connected using existing technologies such as snaps, latches, and magnetic blocks. It should be noted that the hinge between the first clamp 4 and the second clamp 5 has a certain damping effect, which avoids the large impact force generated by the rapid opening and closing of the first clamp 4 and the second clamp 5, thereby protecting the first clamp 4 and the second clamp 5 themselves as well as the stator enameled wire 201 being clamped. At the same time, when the first clamp 4 and the second clamp 5 clamp the stator enameled wire 201, the first clamp 4 and the second clamp 5 can be relatively stably maintained in that position, and the stator enameled wire 201 can be stably clamped between the first clamp 4 and the second clamp 5, and will not easily move relative to the first clamp 4 and the second clamp 5. Furthermore, the top side of the cutting support is provided with three second limiting grooves 1201 for movably inserting the stator enameled wire 201. The three second limiting grooves 1201 correspond to three different phase wires in the stator enameled wire 201. The operator can divide the stator enameled wire 201 on the motor stator 2 into three different phase wires and place the three different phase wires into the three second limiting grooves 1201 respectively, keeping the three different phase wires taut within the second limiting grooves 1201. Since the cutting support is hinged with a cutting blade 6 that can generate shearing force with the edge of the second limiting groove 1201, when the operator operates the cutting blade 6 to rotate towards the phase wires placed in the second limiting groove 1201 to a certain angle, the three bundles of stator enameled wire 201 can be neatly cut along the edge of the second limiting groove 1201.
[0027] In actual use, the operator can first place the motor stator 2 in the positioning groove 101 on the tooling base plate 1 according to the fixed position, and open the wire clamp connected to the pressure plate support, so that the first clamp 4 and the second clamp 5 open. Then, the operator can separate the three different phase wires in the stator enameled wire 201 through the gaps between the fingers, and can close the five fingers so that the fingers can not completely clamp the three sets of phase wires. Then, the operator can pull the phase wires in the direction of extension of the phase wires, so that the phase wires are taut, and the operator's palm can slide relative to the phase wires until the phase wires between the operator's palm and the motor stator 2 are taut and lying flat on the second limit groove 1201 and the first clamp 4 or the second clamp 5 under the operator's action. Then, the operator can close the opened first clamp 4 and the second clamp 5 (the first clamp 4 or the second clamp 5, which is detachably connected to the pressure plate support, remains relatively stationary with respect to the pressure plate support), so that the wire clamp can clamp the phase wires. Then, the operator can operate the cutting blade 6 to cut the phase wires at a fixed distance. Finally, the operator can pick up the motor stator 2 and the wire clamp as a whole, and put the phase wire end into the stripper for stripping. Since the wire clamp has clamped and fixed the phase wire, and the phase wire extending from the wire clamp is cut at a fixed distance by the cutter 6 to keep the length consistent, the operator can use the position of the wire clamp fixed on the phase wire as a reference to perform the stripping operation. Therefore, the stripping length of the phase wire can also be kept consistent, which meets the requirements.
[0028] It should be noted that when the operator places the three taut phase wires into the three second limiting grooves 1201 respectively, the phase wire in the middle second limiting groove 1201 can maintain a straight state, and the cutting blade 6 can cut the phase wire bundle perpendicularly, as shown in the following example. Figure 4 As shown. The two adjacent phase wires will bend at a certain angle under the limitation of the other two limiting grooves, but will still remain taut. In this technical solution, when the two adjacent phase wires are cut by the cutting blade 6 at the same time, the straight-line distance between their cut ends and the wire clamp is not exactly the same as the length of the phase wires cut vertically by the cutting blade 6, but it is still within the allowable error range.
[0029] Furthermore, such as Figure 3As shown, the first clamping block 4 and the second clamping block 5 are provided with first limiting grooves 45 for the stator enameled wire 201 to pass through, and a silicone pad 7 is provided in the first limiting groove 45. The first limiting grooves 45 on the first clamping block 4 and the second clamping block 5 correspond to each other when the first clamping block 4 and the second clamping block 5 are closed, and can form a "U"-shaped structure for looping around the outer periphery of the stator enameled wire 201, which can effectively limit the position of the stator enameled wire 201. At the same time, by providing the silicone pad 7 in the first limiting groove 45, not only can the relative sliding between the stator enameled wire 201 and the clamping device be effectively prevented when the wire clamping device holds the stator enameled wire 201, but it can also prevent the surface of the stator enameled wire 201 from being scratched by the first clamping block 4 and the second clamping block 5.
[0030] Furthermore, such as Figure 2 As shown, the pressure plate support includes multiple short support rods 8 detachably connected to the tooling base plate 1 and support blocks 9 detachably connected to the top of the multiple short support rods 8. Specifically, both the tooling base plate 1 and the support block 9 are provided with stepped through holes (not shown in the figure) for embedding the short support rods 8. The two ends of the short support rods 8 can be respectively embedded in the stepped through holes on the tooling base plate 1 and the support block 9. Both the tooling base plate 1 and the support block 9 are provided with bolts (not shown in the figure) that can pass through the stepped through holes and be threadedly connected to the short support rods 8. By tightening the bolts and the short support rods 8, the structural strength of the pressure plate support and the tooling base plate 1 can be ensured, and it is convenient to adapt to the fixed-distance cutting requirements of motor stators 2 of different specifications by replacing the short support rods 8 and support blocks 9 of different specifications, thereby improving the flexibility of the auxiliary tooling. Similarly, in this technical solution, the cutting support base includes multiple long support rods 11 detachably connected to the tooling base plate 1 and wire divider blocks 12 detachably connected to the top of the multiple long support rods 11. The second limiting groove 1201 is provided on the top side of the wire divider block 12, and the cutting blade 6 is hinged to one end of the wire divider block 12. The long support rods 11, wire divider blocks 12, and tooling base plate 1 can also adopt the above-mentioned detachable connection structure, so as to adapt to the fixed-distance cutting requirements of motor stators 2 of different specifications by replacing the long support rods 11 and wire divider blocks 12 of different specifications.
[0031] The above, such as Figure 2 As shown, the top side of the support block 9 is provided with a contoured groove 901 for movably embedding the first clamping block 4 or the second clamping block 5. That is, when the first clamping block 4 or the second clamping block 5 on the wire clamp is placed in the contoured groove 901 on the support block 9 by the operator, the four periphery of the contoured groove 901 can restrict the displacement of the first clamping block 4 or the second clamping block 5 in the horizontal direction, thereby ensuring the uniqueness of the position of the wire clamp when it is placed on the support block 9.
[0032] Furthermore, in this embodiment, as Figure 2As shown, the cutting blade 6 is equipped with a handle 10, which has anti-slip textures (not shown in the figure) to facilitate the operator's grip. The handle 10 in this technical solution extends the length of the cutting blade 6 when it acts as a lever arm, allowing the operator to cut the phase wire with less force, thereby reducing the operator's labor intensity. Example 2
[0033] Based on Embodiment 1, the bottom side of the contoured groove 901 can be magnetically connected to the first clamping block 4 or the second clamping block 5 via a first magnet (not shown in the figure) to prevent the wire clamp from accidentally detaching when placed in the contoured groove 901, thereby affecting work efficiency. Furthermore, when the first clamping block 4 and the second clamping block 5 clamp the stator enameled wire 201, they can be magnetically connected via a second magnet (not shown in the figure) to further improve the stability of the wire clamp when holding the stator enameled wire 201.
[0034] It should be noted that the magnetic attraction force between the first magnet and the bottom side of the first clamping block 4 and the contoured groove 901, between the second clamping block 5 and the bottom side of the contoured groove 901, and between the second magnet and the first clamping block 4 and the second clamping block 5 are relatively weak. The operator can manually remove the wire clamp from the support block 9 and separate the first clamping block 4 and the second clamping block 5.
[0035] Working principle: The operator first places the motor stator 2 in the positioning groove 101 on the tooling base plate 1 at a fixed position, and opens the wire clamp connected to the pressure plate support, causing the first clamp 4 and the second clamp 5 to open. The operator then separates the three different phase wires in the stator enameled wire 201 through their fingers, and can close their fingers to partially clamp the three sets of phase wires. The operator then pulls the phase wires in the direction of their extension, tautening them while their palm slides relative to the phase wires until the phase wires between the operator's palm and the motor stator 2 are taut and lying flat in the first limiting groove 45 and the second limiting groove 1201 under the operator's action. The operator then closes the opened first clamp 4 and second clamp 5, clamping the phase wires. Finally, the operator operates the cutting blade 6 to cut the phase wires at a fixed distance. Finally, the operator can pick up the motor stator 2 and the wire clamp as a whole, and put the phase wire end into the stripper for stripping. Since the wire clamp has clamped and fixed the phase wire, and the phase wire extending from the wire clamp is cut at a fixed distance by the cutter 6 to keep the length consistent, the operator can use the position of the wire clamp fixed on the phase wire as a reference to perform the stripping operation. Therefore, the stripping length of the phase wire can also be kept consistent.
[0036] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
