Description

Technical Field

[0001] This utility model relates to the technical field of groove wedge processing devices, and in particular to a groove wedge forming machine. Background Technology

[0002] Slot wedges are widely used in motors, and their manufacturing requires various processes. Currently, many slot wedge forming machines on the market have limited functions. The raw material plates for slot wedges need to go through multiple steps such as cutting, trimming, and slicing, and are completed by various slot wedge forming machines. Moreover, continuous operation cannot be achieved, and the processed products still need further processing.

[0003] Therefore, in the prior art, a groove wedge forming machine, with publication number CN209849969U, the cutting mechanism includes a cutting fixed seat, a cutting telescopic rod, a cutting head mounting seat, and a cutting head. The cutting fixed seat is fixed on the cutting frame support, the upper end of the cutting telescopic rod is mounted on the cutting fixed seat, and the cutting head is mounted on the lower end of the cutting telescopic rod through the cutting head mounting seat. The cutting head is a flat, long cutting head, the cutting edge of the cutting head is parallel to the plane of the cutting table, and the length of the cutting edge of the cutting head is the same as the width of the cutting table.

[0004] In this device, the cutter head is fixed, and during long-term processing, the friction between the cutter and the workpiece will cause the cutter head to wear out quickly. Furthermore, using only flat long cutters lacks flexibility and cannot adapt to the cutting needs of different materials. When cutting different materials, different cutters need to be replaced. The process of stopping the machine for maintenance and replacing cutters in this device is quite troublesome. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art and to propose a groove wedge forming machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a slot wedge forming machine, comprising a cutter head telescopic rod and a cutter head, wherein a mounting plate is fixedly connected to the piston end of the cutter head telescopic rod, a turntable is rotatably connected to one end of the mounting plate, a plurality of connecting sleeves arranged in a circular array are fixedly connected to the bottom of the turntable, a liftable mounting seat is provided at the bottom of the connecting sleeve, the top of the mounting seat extends outward to form an extension edge, the mounting seat is fitted and installed with the connecting sleeves through the extension edge, and a spring is fixedly connected between the top of the extension edge and the turntable, the bottom of the mounting seat is fixed to the cutter head, and a positioning rod that penetrates the turntable is fixedly connected to the top of the mounting seat.

[0007] Preferably, a threaded rod is threadedly connected to the mounting plate, and the bottom of the threaded rod is rotatably mounted to the turntable.

[0008] Preferably, the upper surface of the turntable is fixedly connected with a plurality of limiting sleeves that correspond one-to-one with the position and quantity of the connecting sleeves, and the bottom of the mounting plate is fixedly connected with a positioning post located directly below the piston end of the cutter head telescopic rod. The positioning post is used to insert into the limiting sleeves and its bottom end is used to abut against the positioning rod.

[0009] Preferably, the mounting base has a slot at the bottom, the top of the blade head is fixedly connected to an insert plate, the insert plate is inserted into the slot, and a pin is inserted into one side of the mounting base to engage with the insert plate.

[0010] Preferably, the threaded rod is threaded with a nut located above the mounting plate.

[0011] Preferably, multiple cutter heads rotate around the center of the turntable and can all move to directly below the piston end of the cutter head telescopic rod through rotation.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting multiple cutter heads, a turntable, a connecting sleeve, and a mounting base, the rapid switching of different cutter heads is realized. When a cutter head wears out during processing or when different processing requirements arise, there is no need to perform a complicated cutter head replacement operation.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] like Figure 1-4 As shown, a slot wedge forming machine includes a telescopic rod 1 and a cutter head 7. The piston end of the telescopic rod 1 is fixedly connected to a mounting plate 2. One end of the mounting plate 2 is rotatably connected to a turntable 8. The bottom of the turntable 8 is fixedly connected to a plurality of connecting sleeves 5 arranged in a circular array. The bottom of the connecting sleeves 5 is provided with a liftable mounting seat 9. The top of the mounting seat 9 extends outward to form an extension edge 16. The mounting seat 9 is fitted and installed with the connecting sleeves 5 through the extension edge 16, and a spring 13 is fixedly connected between the top of the extension edge 16 and the turntable 8. The bottom of the mounting seat 9 is fixed to the cutter head 7, and the top is fixedly connected to a positioning rod 6 that passes through the turntable 8. The plurality of cutters 7 rotate around the center of the turntable 8 and can all move to directly below the piston end of the telescopic rod 1 through rotation.

[0023] In this technical solution, multiple cutter heads 7 arranged in a ring array rotate around the center of the turntable 8 and can all move to the position directly below the piston end of the cutter head telescopic rod 1, which can realize the rapid switching of different cutter heads 7. Specifically, when a cutter head 7 wears out during processing or when different processing requirements are met, there is no need to perform a complicated cutter head 7 replacement operation. The spare cutter head 7 can be quickly positioned by rotating the turntable 8, which greatly improves processing efficiency.

[0024] By setting the positioning rod 6, positioning post 14 and limiting sleeve 15, the position of the cutting head 7 can be accurately determined, ensuring that the cutting head 7 is in the accurate working position after each switching, thus further ensuring the accuracy of processing.

[0025] like Figure 1 As shown, a threaded rod 3 is threadedly connected to the mounting plate 2. The bottom of the threaded rod 3 is rotatably mounted to the turntable 8. A nut 4 located above the mounting plate 2 is threadedly connected to the threaded rod 3.

[0026] In this technical solution, by rotating the threaded rod 3, which is threadedly connected to the mounting plate 2, the threaded rod 3 will move up and down along the thread, thereby driving the rotating disk 8 to move up and down. When the disk 8 moves downward, it drives the limiting sleeve 15 to move downward, while the position of the positioning pin 14 remains unchanged. The positioning pin 14 separates from the limiting sleeve 15. At this time, the disk 8 can be rotated to move the cutter head 7 to be used to the position directly below the piston end of the cutter head telescopic rod 1. Furthermore, after the spare cutter head 7 is adjusted, the nut 4 located above the mounting plate 2 is tightened. The nut 4 will press tightly against the mounting plate 2, using the self-locking characteristic of the thread to prevent the threaded rod 3 from rotating due to vibration or other reasons during operation.

[0027] like Figure 3 As shown, multiple limiting sleeves 15, corresponding one-to-one in position and quantity to the connecting sleeves 5, are fixedly connected to the upper surface of the turntable 8. A positioning post 14, located directly below the piston end of the cutter head telescopic rod 1, is fixedly connected to the bottom of the mounting plate 2. The positioning post 14 is used to insert into the limiting sleeves 15 and its bottom end is used to abut against the positioning rod 6.

[0028] In this technical solution, by setting a spring 13, when the positioning pin 14 abuts against the positioning rod 6 downwards, it pushes the positioning rod 6 downwards, and the spring 13 relaxes, causing the cutter head 7 to be used to move downwards. Meanwhile, the height of the other cutter heads 7 remains unchanged under the action of the spring 13. At this time, the cutter head 7 to be used protrudes downwards relative to the other cutter heads 7, which is convenient and practical, and prevents the cutter head 7 to be used from being interfered with by the other cutter heads 7 during operation.

[0029] like Figure 2 and Figure 3 As shown, the mounting base 9 has a slot 12 at the bottom, and the top of the blade 7 is fixedly connected to the insert plate 11. The insert plate 11 is inserted into the slot 12, and a pin 10 is inserted into one side of the mounting base 9 to be inserted into the insert plate 11.

[0030] Working principle: When switching the cutter head 7, rotating the threaded rod 3 causes the turntable 8 to move downwards, separating the positioning pin 14 from the limiting sleeve 15. Then, rotating the turntable 8 rotates the spare cutter head 7 to be directly below the piston end of the cutter head telescopic rod 1. Next, rotating the threaded rod 3 in the opposite direction causes the turntable 8 to rise, and the positioning pin 14 inserts into the limiting sleeve 15 for positioning. At the same time, the positioning pin 14 pushes the positioning rod 6 to make the cutter head 7 in use protrude from the other cutter heads 7. After that, the switch is completed by tightening the nut 4 to fix it.

[0031] The wiring diagram of the telescopic rod 1 of the cutter head in this utility model is common knowledge in the field. Its working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the telescopic rod 1 will not be explained in detail.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
