Description

Technical Field

[0001] This utility model belongs to the field of honing technology, specifically relating to a gantry-type single-shaft honing machine. Background Technology

[0002] Honing is a primary method for precision machining of internal holes in manufactured parts, and honing machines are commonly used equipment in modern machinery, utilizing honing heads to perform precision machining on workpiece surfaces. Under certain conditions, it can also machine planes, external cylindrical surfaces, and spherical surfaces. However, current equipment only has two degrees of freedom (XZ or YZ), limiting the machining range of honing. To address the problems existing in current technology, people have conducted long-term research and proposed various solutions.

[0003] Vertical honing machines are now available, such as the Chinese patent document CN206123414U.

[0004] The technical drawback is that the honing head can only move along the Z-axis, which greatly limits its processing capabilities. Utility Model Content

[0005] The technical problem this invention aims to solve is: how to design a honing head with more freedom compared to a gantry-type single-shaft honing machine.

[0006] The specific technical solution of this utility model is as follows:

[0007] A gantry-type single-axis honing machine includes a base with a Y-axis track for workpiece movement. Two gantry columns—a front column and a rear column—are fixed at the four corners of the base, with the space between the two columns serving as the processing space. A housing is fixed to the top of the two columns, and an X-axis track is mounted on the housing. A honing spindle unit that can slide along the X-axis track is mounted on the X-axis track. An X-axis motor is fixed to the housing, and a lead screw is fixed to the output shaft of the X-axis motor. The lead screw is threadedly connected to the honing spindle unit, and the X-axis motor provides power for the movement of the honing spindle unit. A honing processing mechanism is mounted on the honing spindle unit.

[0008] The main machining mechanism is located in the middle of the front column and the rear column.

[0009] Compared with the prior art, the technical effect of this utility model is that it is equipped with a gantry frame, which allows the honing spindle to move on the X-axis and move in conjunction with the Y-axis of the workpiece, so that the honing spindle (honing head) and the workpiece can be horizontally positioned in two dimensions, and the honing head has more degrees of freedom.

[0013] Figure 4 This is a three-dimensional schematic diagram of the present invention. Detailed Implementation

[0014] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0015] like Figure 1-4 A gantry-type single-axis honing machine includes a base 1, a Y-axis track 22 for moving the workpiece, and two gantry columns fixed at the four corners of the base 1: a front column 2 and a rear column 3. The space between the two gantry columns is the processing space.

[0016] Both columns are fixed to the top of a housing 19. The housing 19 is equipped with an X-axis rail 20. The X-axis rail 20 is equipped with a honing spindle unit 7 that can slide along it. The housing 19 is fixed with an X-axis motor 6. The output shaft of the X-axis motor 6 is fixed with a lead screw 23. The lead screw 23 is threadedly engaged with the honing spindle unit 7. In this way, the Y-axis motor 6 provides power for the movement of the honing spindle unit 7.

[0017] The honing spindle unit 7 is equipped with a honing mechanism. This honing mechanism is existing technology and not an improvement upon the present patent. The honing mechanism includes a Z-axis motor 8, which is fixed to the honing spindle unit 7. Its output shaft is fixed to a Z-axis lead screw, which is threaded into a three-piece assembly. The three-piece assembly slides within the honing spindle unit 7. The Z-axis motor 8 provides power for the movement of the three-piece assembly.

[0018] The honing spindle is fixed on the triple unit, the rotary motor is fixed on the honing spindle unit 7, the lower part of the honing spindle unit 7 is fixed with a clamping system 12, the honing spindle is connected to the honing tool 4, the honing tool 4 is equipped with a control motor 9 that can control the position of the tool head on the tool body, the control motor 9 is connected to the tool holder through the linkage mechanism 13, the tool head is fixedly connected to the tool holder, and the tool holder is movably connected to the tool body.

[0019] For ease of control, the X-axis motor 6, rotary motor, Z-axis motor 8, and control motor 9 are all electrically connected to the controller 5.

[0020] To maintain machining accuracy, the main machining mechanism is located between the front column 2 and the rear column 3. Honing is a high-precision machining process that generates a large reaction force. This reaction force causes deformation of the top seat 19, which is supported by four columns. The main machining mechanism's location between the front column 2 and the rear column 3 minimizes the deformation of the top seat 19, thus reducing its impact on the honing accuracy.

[0021] Its working principle is as follows:

[0022] S1. This utility model is equipped with a gantry frame, which allows the honing spindle to move on the X-axis and move in conjunction with the Y-axis of the workpiece, so that the honing spindle (honing head) and the workpiece can be horizontally positioned in two dimensions, and the honing head has more degrees of freedom.

[0023] S2. The top seat supporting the honing head is very stable, which can minimize the impact on the accuracy of the honing process.

[0024] For other details, please refer to the existing technology.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
