Description

Technical Field

[0001] This utility model relates to the field of machining tooling technology, and in particular to a lightweight tooling for machining tool grooves. Background Technology

[0002] In the field of machining, the machining accuracy and efficiency of cutting tools are crucial to the entire production process. This is especially true for common and widely used tools such as round inserts, where the machining quality of the tool grooves directly affects the insert's performance and cutting effect.

[0003] Currently, the tooling used in the machining of circular insert tool grooves has many shortcomings. From the perspective of tool clamping stability, existing tooling often clamps the cutting face of the circular insert. However, the smooth surface of the cutting face is prone to slippage, leading to wobbling or displacement of the circular insert during machining. This affects the machining accuracy of the tool groove, resulting in significant dimensional deviations and failing to meet high-precision machining requirements. Furthermore, multiple adjustments for positioning are necessary. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

A toggle shaft is rotatably mounted on the mounting plate, and a worm gear is fixedly sleeved on the toggle shaft. The worm gear is connected to the gear plate for transmission, and an external hexagonal nut is fixedly connected to the end of the toggle shaft.

[0013] As a preferred embodiment of the lightweight tooling for machining tool grooves according to the present invention, a plurality of bottom support rods are passed through the top of the outer shell, the bottom support rods are threadedly connected to the outer shell, and the bottom support rods are used to support the tool.

[0028] Example

[0029] Reference Figures 1-4 As an embodiment of the present invention, a lightweight tooling for machining tool grooves is provided, including: a clamping unit 100 and an adjusting unit 200.

[0030] The clamping unit 100 includes a housing 101. A bracket 102 is symmetrically fixedly installed on the bottom of the housing 101. A plurality of sliding grooves 103 are provided on the housing 101. A slide rail 104 is fixedly installed radially inside the sliding grooves 103 along the housing 101. A support frame 105 is slidably sleeved on the slide rail 104. The support frame 105 passes through the sliding grooves 103. A tool clamping block 106 is fixedly connected to the top of the support frame 105. A limiting groove 107 adapted to the shape of the tool is provided on the tool clamping block 106.

[0031] The slide groove 103 is provided in four parts, and is distributed in a circular array around the center of the outer shell 101.

[0032] A pre-drilled hole 108 is provided at the center of the top of the outer shell 101. A connecting ring 109 is fixedly connected to the bottom of the pre-drilled hole 108. The gear disk 201 is sleeved on the connecting ring 109. The gear disk 201 and the connecting ring 109 are rotatably connected. Limiting rings 110 are symmetrically fixedly connected on the connecting ring 109 and on the upper and lower sides of the gear disk 201.

[0033] A plurality of bottom support rods 111 extend through the top of the outer casing 101. The bottom support rods 111 are threadedly connected to the outer casing 101 and are used to support the cutting tool.

[0034] The inner wall of the limiting groove 107 on the tool clamping block 106 is provided with an anti-slip layer 112, which is made of rubber material. The bottom of the bracket 102 is provided with a shock-absorbing pad 113, which is made of elastic rubber material.

[0035] The adjustment unit 200 includes a geared disc 201, the interior of which is provided with a plurality of arc-shaped grooves 202, and the bottom end of the support frame 105 extends into the interior of the arc-shaped grooves 202. The geared disc 201 is a type of turbine.

[0036] The adjustment unit 200 also includes a mounting plate 203, which is fixedly installed on one side of the housing 101. A toggle shaft 204 is rotatably mounted on the mounting plate 203. A worm gear 205 is fixedly sleeved on the toggle shaft 204. The worm gear 205 is connected to the gear plate 201 for transmission. An external hexagonal nut 206 is fixedly connected to the end of the toggle shaft 204.

[0037] During use, rotate the bottom support rod 111 and adjust its height according to the thickness and shape of the tool to provide stable support for the tool, ensuring that its top can contact the bottom of the tool. Place the tool to be processed on the bottom support rod 111 and use a suitable wrench to turn the external hex nut 206. The external hex nut 206 drives the actuating shaft 204 to rotate. Since the actuating shaft 204 is fixedly sleeved with a worm gear 205, the worm gear 205 rotates accordingly. The transmission between the worm gear 205 and the gear plate 201 causes the gear plate 201 to rotate on the connecting ring 109. The arc groove 202 inside the gear plate 201 pushes the support frame 105 to slide radially along the outer shell 101 on the slide rail 104. The support frame 105 drives the tool clamping blocks 106 to move closer to each other, gradually clamping the tool until the tool is firmly fixed between the tool clamping blocks 106. During the clamping process, the rubber anti-slip layer 112 on the inner wall of the limiting groove 107 increases the friction between the tool and the tool clamping block 106, ensuring that the tool will not slip, and also protecting the cutting edge of the tool from damage caused by pressure.

[0038] Place the tooling with the tool installed on the worktable of the machining equipment, and use the positioning device of the machining equipment to ensure that the tooling and the tool are in the correct machining position.

[0039] Start the machining equipment and perform grooving on the tool according to the preset machining parameters. During the machining process, the elastic rubber shock-absorbing pad 113 at the bottom of the support 102 absorbs and buffers the vibration generated during machining, reducing the impact of vibration on the tool and tooling; the bottom support rod 111 continuously provides stable support for the tool, ensuring the stability and accuracy of machining.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
