Abstract
Description
Technical Field
[0001] This utility model relates to the industrial and mining fields, specifically a clamping tool for precision machining ring-shaped parts. Background Technology
[0002] As a crucial component in motor assembly, the gear clamping plate directly impacts motor profits through its production cost and efficiency. Due to its thin profile, it is highly susceptible to deformation during machine tool clamping. High cutting forces exacerbate this deformation, further intensifying the unstable working conditions. Additionally, the large and irregular allowance makes depth of cut difficult to control. Traditional machining methods utilize a sharp high-speed steel tool; to ensure machining safety, at least three passes are required, each return trip representing a waste of time and significantly increasing the workload for operators. Utility Model Content
[0003] To solve the above problems, this utility model discloses a tooling for facilitating the processing of motor tooth pressure plates.
[0004] The specific technical solution is as follows:
[0005] A tooling for facilitating the machining of motor gear pressure plates, comprising:
[0006] The main tool body is used for fixed connection with the machine tool tool post;
[0007] Three tool holders: a roughing tool holder, a semi-finishing tool holder, and a finishing tool holder. The roughing tool holder and the semi-finishing tool holder are welded and fixed to the main tool body. The finishing tool holder is installed on the main tool body by a tool holder locking screw. The adjusting screw is set in the opposite position of the finishing tool holder and screwed to the finishing tool holder, and installed on the main tool body.
[0008] The roughing insert, semi-finishing insert, and finishing insert are respectively mounted on three tool holders, and each insert is fixed by a locking screw.
[0009] The laser positioning assembly includes a green laser emitter, a laser emitter bracket, a side pressure handle, and a bracket locking screw. The green laser emitter is fixed on the laser emitter bracket, and a side pressure handle is fixedly connected to one side of the laser emitter bracket. The side pressure handle is inserted into the main tool body. The horizontal green light emitted by the green laser emitter is parallel to the Z-axis of the machine tool, and the emission path of the light precisely passes through the tip of the finishing insert.
[0010] The laser positioning component also includes a dial, which is mounted on the finishing tool holder and is used to precisely control the radial position of the finishing tool in conjunction with the adjusting screw.
[0011] The tips of the roughing insert and the semi-finishing insert are offset by a set distance along the axial direction to ensure that only one insert participates in the cutting process.
[0012] The green laser emitter is adjustablely mounted on the side of the main blade body via a side-pressure handle. After adjustment, it is fixed by a bracket locking screw so that the spatial position of the light and the finishing blade tip satisfies the following condition: when the light is projected onto the inner side of the workpiece, the finishing blade is at the X-axis cutting start point.
[0013] The axial arrangement of the three tool holders satisfies the timing cutting conditions: after the roughing tool completes the cutting, the semi-finishing tool continues the cutting, and finally the finishing tool performs the machining.
[0014] The advantages of this utility model are:
[0015] By integrating three sequential cutting tools for roughing, semi-finishing, and finishing into the main tool body and employing a welded rigid connection to ensure stability in roughing and semi-finishing, combined with the fine-tuning structure of the finishing tool holder's dial and a green laser positioning system, multi-process machining can be completed in a single clamping, completely eliminating the wasted idle travel time of traditional multiple tool passes, improving efficiency by more than 3 times; the design of the laser beam precisely passing through the finishing tool tip allows the laser spot on the inner side of the workpiece to directly indicate the X-axis cutting start point, solving the problem of dimensional loss of control caused by tool setting errors in thin-walled parts; the axially misaligned tool tip arrangement forces the tools to perform sequential cutting, avoiding vibration caused by simultaneous multi-tool machining, significantly extending tool life and ensuring part machining accuracy, and comprehensively reducing production costs and labor intensity.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] A tooling for facilitating the machining of motor gear pressure plates, comprising:
[0020] Main tool body 1, used for fixed connection with the machine tool tool post;
[0021] Three tool holders: a roughing tool holder 6, a semi-finishing tool holder 8, and a finishing tool holder 10. The roughing tool holder 6 and the semi-finishing tool holder 8 are welded and fixed to the main tool body 1. The finishing tool holder 10 is installed on the main tool body 1 by a tool holder locking screw 4. An adjusting screw 5 is set at the opposite position of the finishing tool holder 10 and screwed to the finishing tool holder 10, and is installed on the main tool body 1.
[0022] The roughing insert 2, the semi-finishing insert 7, and the finishing insert 9 are respectively installed on three tool holders, and each insert is fixed by a locking screw 3.
[0023] The laser positioning assembly includes a green laser emitter 11, a laser emitter bracket 12, a side pressure handle 13, and a bracket locking screw 14. The green laser emitter 11 is fixed on the laser emitter bracket 12. The side pressure handle 13 is fixedly connected to one side of the laser emitter bracket 12. The side pressure handle 13 is inserted into the main tool body 1. The horizontal green light 17 emitted by the green laser emitter 11 is parallel to the Z-axis direction of the machine tool. The emission path of the light 17 precisely passes through the tip of the finishing insert 9.
[0024] The laser positioning assembly also includes a dial 16, which is mounted on the finishing tool holder 10 and is used to precisely control the radial position of the finishing blade 9 in conjunction with the adjusting screw 5.
[0025] The tips of the roughing insert 2 and the semi-finishing insert 7 are offset by a set distance along the axial direction to ensure that only one insert participates in the cutting process.
[0026] The green laser emitter 11 is adjustablely mounted on the side of the main cutter body 1 via a side-pressure handle 13, and is fixed by a bracket locking screw 14 after adjustment, so that the spatial position of the light beam 17 and the finishing tool tip satisfies the following condition: when the light beam is projected onto the inner surface of the workpiece 15, the finishing tool 9 is at the X-axis cutting start point (e.g., when the light beam is projected onto the inner surface of the workpiece 15, the finishing tool 9 is at the X-axis cutting start point). Figure 1 ).
[0027] The axial arrangement of the three tool holders satisfies the timing cutting conditions: after the roughing tool 2 completes the cutting, the semi-finishing tool 7 continues the cutting, and finally the finishing tool 9 performs the machining.
[0028] The working principle of this utility model is as follows: the main tool body 1 is fixedly connected to the machine tool post, the roughing tool bar 6 and the semi-finishing tool bar 8 are welded to the main tool body 1, and the positions of the tool tips of the two are about 2mm apart to ensure rigidity and stability during cutting; the finishing tool bar 10 is installed on the main tool body 1 by the tool bar locking screw 4, and is finely adjusted in the front and back direction by the finishing tool bar position adjustment screw 5, and is precisely positioned by the scale 16 to control the finishing allowance.
[0029] The green laser emitter 11 is mounted on the main tool body 1 via a bracket 12. The horizontal green light 17 emitted by the green laser emitter 11 is parallel to the Z-axis of the machine tool (e.g., ...). Figure 1 And it passes precisely through the tip of the finishing insert 9. During machining, when the light beam 17 hits the inside of the workpiece, it determines the cutting position on the X-axis, enabling rapid tool setting.
[0030] The three-insert-bar design ensures that only one insert participates in cutting during machining. The next insert only intervenes after the previous insert has finished cutting, avoiding excessive cutting forces generated by multiple inserts cutting simultaneously and reducing the impact of vibration on tool life and part dimensional stability. With this structure, the fixture can sequentially complete roughing, semi-finishing, and finishing, reducing the wasted idle strokes of multiple tool passes in traditional machining, improving machining efficiency, and ensuring accuracy.
