Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a tooling fixture used for processing workpiece drilling. Background Art

[0002] Machining refers to the process of changing the shape, size or performance of a workpiece through a mechanical device. It can be divided into cutting and pressure processing according to the difference in processing methods. In the process of processing the workpiece, drilling is a common processing method in mechanical processing.

[0003] In the prior art, when drilling a hole in a workpiece, the workpiece is generally placed directly on a workpiece fixture for holding a bracket, and then the workpiece fixture is placed on a support column so that the middle of the workpiece fixture is suspended in the air to facilitate the drilling of the workpiece. It should be noted that, when drilling holes in mechanical processing, holes are generally drilled at the center of the fixture. Therefore, while ensuring the stability of the workpiece, the existing workpiece fixture only has a hollow structure in the middle to accommodate the hollow hole of the workpiece to facilitate the drilling of the workpiece. However, once the mechanical processing of the workpiece requires the workpiece to be processed at other radial positions besides the center position, for the currently existing mechanical fixtures, once the workpiece needs to be processed at other positions along its radial direction except the center position, the drill bit is required to be able to move to the top of the corresponding position, and it is also necessary to ensure that the corresponding bottom position of the workpiece fixture for drilling is difficult to meet the requirement of being suspended in the air, so that the drilling cannot be completed.

[0022] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figure 1 As shown, the utility model proposes a tool fixture for drilling a workpiece, and the tool fixture is used to support the workpiece to be processed.

[0024] In this embodiment, see Figure 1 As shown, the tooling includes a base body 1, an axially vertically arranged driving member 2 arranged on the base body 1, a ball screw 3 arranged at the output end of the driving member 2, and the nut on the ball screw 3 is fixedly connected with an adjusting support body 4 that can make horizontal reciprocating motion along the axial direction of the screw on the ball screw 3 and a fixed supporting body 5 fixedly sleeved on the outside of the ball screw 3, and the adjusting support body 4 is arranged above the fixed supporting body 5.

[0025] It should be noted that the fixed support body 5 is used to support two points on the diagonal line of the bottom end face of the workpiece, and the driving member 2 can drive the adjustable support body 4 to rise along the axial direction of the ball screw 3 to lift the tooling fixture on the fixed support body 5 to support the other two points on the diagonal line of the bottom end face of the workpiece.

[0026] Or when it is necessary to drill a hole directly above the earphone support body 4, the adjustable support body 4 can be driven to lower along the axial direction of the ball screw 3, and the workpiece can be dropped onto the fixed support body 5, and the adjustable support body 4 and the fixed support body 5 can alternately contact the bottom end surface of the workpiece.

[0027] In this embodiment, a tooling for supporting the workpiece for processing is arranged under the workpiece, and the tooling includes a base body and a driving member arranged on the base body for driving the ball screw to rotate. In this embodiment, the workpiece is initially placed on the fixed support body to ensure that the center of the workpiece and the two ends of the diagonal contacting the workpiece can be drilled. When it is necessary to drill holes at two points of the diagonal, the adjustable support assembly can be driven by the driving member to move upward along the ball screw until the adjustable support body props up the two points of another diagonal of the workpiece, so as to facilitate drilling at the support point of the fixed support body, thereby making the mechanical processing drilling more comprehensive, simple and convenient to operate, and highly purposeful. It can better perform mechanical processing. In this embodiment, it is solved that for the existing mechanical tooling, once the workpiece needs to be processed and drilled at other positions except the center position along its radial direction, the drill bit is required to be able to move to the corresponding position directly above, and it is also necessary to ensure that the corresponding bottom position of the workpiece fixture for processing the drilling is difficult to meet the requirement of being suspended, so that the drilling cannot be completed in coordination.

[0028] Furthermore, the fixed support body 5 includes a fixed bracket 51 and a first support chuck 52 disposed at both ends of the fixed bracket 51. The fixed bracket 51 is mounted on the ball screw 3 through a bearing sleeve. The first support chuck 52 is disposed perpendicular to the top end surface of the fixed bracket 51 and extends upward in the vertical direction, and a first step end surface for placing a workpiece is formed between the first support chuck 52 and the end surface of the fixed bracket 51. The purpose of providing the first step end surface is to play a role in positioning the workpiece in the circumferential direction and the axial direction, respectively, so as to facilitate machining and drilling.

[0029] Furthermore, the adjusting support body 4 includes an adjusting bracket 41 and second supporting chucks 42 arranged at two ends of the adjusting bracket 41. The adjusting bracket 41 is sleeved on the ball screw 3 through a nut of the ball screw 3.

[0030] The second support chuck 42 is arranged perpendicular to the top end face of the adjustment bracket 41 and extends upward in the vertical direction, and a second step end face for placing the workpiece is formed between the second support chuck 42 and the end face of the adjustment bracket 41, and the height of the second support chuck 42 in the vertical direction is less than the height of the first support chuck 52 in the vertical direction. The purpose of setting the second step end face of the adjustment support body 4 is also to play a role in positioning the workpiece in the circumferential and axial directions when the workpiece is supported, so as to facilitate mechanical processing and drilling.

[0031] Furthermore, the first support chuck 52 and the second support chuck 42 are detachably connected to the top end surfaces of the corresponding fixed bracket 51 and the adjustment bracket 41, and the first support chuck 52 and the second support chuck 42 can respectively move along the radial direction of the corresponding bracket to position the workpiece, so as to adapt to different workpieces, and be easy to install and replace.

[0032] Furthermore, the driving member 2 includes a driving motor, an electric control structure member disposed in the base body 1, and the driving motor is communicatively connected with the electric control structure member. Specifically, the driving motor and the ball screw 3 are connected by a speed reducer to reduce the speed of the driving motor, so that the electric control structure member can control the ball screw 3. It should be noted that the electric control structure member is an existing control member and will not be described in detail here.

[0033] Furthermore, the angle between the fixed support body 5 and the adjustable support body 4 is 75° or 105°. The setting of this angle facilitates the installation and disassembly between the fixed support body 5 and the adjustable support body.

[0034] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
