Description

Technical Field

[0001] This utility model relates to the field of honing technology, and in particular to a deep hole honing machine tool with a movable clamp. Background Technology

[0002] Due to the need for deep hole machining, deep hole honing is now used not only in metal processing but also in the processing of non-metallic materials such as quartz tubes and glass tubes. The machined quartz tubes are used by customers in semiconductor and optical communication applications, where extremely high precision is required for the inner bore.

[0003] Existing deep hole honing machines are equipped with a movable bracket that can move left and right. The movable bracket is generally adjusted by two lead screws moving up and down to adjust the center of the cylinder bore and the honing rod, and the tube to be processed is locked with a chain. This locking method is effective for heavy metal materials, but it is easy to cause shaking when locking non-metallic materials such as quartz tubes and glass tubes. During processing, the tube will rotate, affecting the processing accuracy and efficiency. Utility Model Content

[0004] In view of the defects existing in the prior art, the technical problem to be solved by this utility model is to provide a deep hole honing machine tool with a moving fixture that is suitable for various pipe sizes, can quickly lock, has a firm locking method that prevents pipes from shifting or rotating, and can improve processing accuracy and efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides a deep hole honing machine tool with a movable clamp, comprising a machine tool body, on which two parallel transverse guide rails are provided, characterized in that:

[0006] At least one movable clamp is provided on the transverse guide rail. The movable clamp includes a three-jaw chuck and an L-shaped bracket that can slide left and right along the transverse guide rail. The L-shaped bracket is provided with a locking device for locking the L-shaped bracket on the transverse guide rail. A through hole for the pipe to be processed is opened on the vertical surface of the L-shaped bracket. A rotatable slewing bearing is installed on the L-shaped bracket. The three-jaw chuck is fixed on the slewing bearing by an adapter ring. The slewing bearing, adapter ring, and three-jaw chuck are arranged concentrically with the through hole. The slewing bearing is provided with external teeth. A drive motor is also installed on the L-shaped bracket. A drive gear is provided on the shaft of the drive motor. The drive gear meshes with the external teeth on the slewing bearing.

[0007] The deep hole honing machine tool with a movable clamp provided by this utility model uses a three-jaw chuck to hold the pipe. For pipes of different diameters, there is no need to adjust the center of the pipe vertically. Compared with the existing chain winding locking method, the locking is fast. After the three-jaw chuck locks, the pipe is not easy to shift or rotate, which can improve the processing accuracy and efficiency. Attached Figure Description

[0008] Figure 1 This is a schematic diagram of the structure of a deep hole honing machine tool with a movable clamp according to an embodiment of the present invention;

[0009] Figure 2 This is a front view of the movable clamp according to an embodiment of the present utility model;

[0010] Figure 3 This is a side view of the movable clamp according to an embodiment of the present invention. Detailed Implementation

[0011] The embodiments of this utility model are described in further detail below with reference to the accompanying drawings. However, these embodiments are not intended to limit this utility model. Any similar structures or variations thereof that adopt this utility model should be included in the protection scope of this utility model. The commas in this utility model all indicate the relationship between and.

[0012] like Figures 1-3 As shown, the deep hole honing machine tool with a movable clamp provided in this embodiment of the present invention includes a machine tool body 1, and two parallel transverse guide rails 2 are provided on the machine tool body 1.

[0013] At least one movable clamp 3 is provided on the transverse guide rail 2. The movable clamp 3 includes a three-jaw chuck 34 and an L-shaped bracket 31 that can slide left and right along the transverse guide rail. The L-shaped bracket 31 is provided with a locking element (not shown in the figure) for locking the L-shaped bracket 31 on the transverse guide rail 2. A through hole for the pipe to be processed is opened on the vertical surface of the L-shaped bracket 31. A rotatable slewing bearing 32 is installed on the L-shaped bracket 31. The three-jaw chuck 34 is fixed on the slewing bearing 32 by a transition ring 33. The slewing bearing 32, the transition ring 33 and the three-jaw chuck 34 are arranged concentrically with the through hole. The slewing bearing 32 is provided with external teeth. A drive motor 4 is also installed on the L-shaped bracket. A drive gear 41 is provided on the shaft of the drive motor 4. The drive gear 41 meshes with the external teeth on the slewing bearing 32.

[0014] The device provided in this embodiment of the utility model is suitable for honing pipe fittings;

[0015] Before processing the pipe fitting, the pipe fitting to be processed is passed through each of the three-jaw chucks 34 on the transverse guide rail 2, and each movable jaw of the three-jaw chuck 34 clamps the pipe fitting. The moving fixture 3 is moved horizontally on the transverse guide rail 2. After the pipe fitting to be processed is moved to match the stroke of the honing rod (not shown in the figure) of the honing machine, the moving fixture 3 is locked on the transverse guide rail 2 by the locking device on the L-shaped bracket 31. Then the honing machine can be started to extend the honing rod into the pipe fitting for processing.
