Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature alloy pin hole processing, in particular to a deep hole processing machine tool. Background Art

[0002] High temperature alloy pin hole processing refers to the process of drilling or other processing operations on high temperature alloy materials. High temperature alloys have good high temperature strength, corrosion resistance and thermal fatigue resistance, and are often used in aerospace, energy, chemical and other fields.

[0003] A deep hole processing machine tool disclosed in announcement number CN213615474U can solve the problem of severe vibration of the tool and damage to the tool due to the tool being too long by fixing the tool at two positions. A shock-absorbing pad is provided on the clamping device to reduce the vibration of the tool during the processing and increase the service life of the tool. A guide device is provided to play a centering and sealing role during processing.

[0004] However, compared with the existing technologies in the related fields, when it is necessary to open a plurality of evenly distributed holes on a shaft component, it is necessary to use a rotary clamping mechanism to control the rotation of the shaft component, and then drill holes through a drilling device. However, in actual operation, due to the influence of a certain amount of center offset and inertia of the shaft component after the rotation adjustment of the rotary clamping mechanism, the shaft component will produce a slight displacement, and this slight displacement will cause errors in the spacing between the multiple holes, thus affecting the production quality of the shaft component. Utility Model Content

[0006] The purpose of the utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background technology, and provide a deep hole processing machine tool.

[0007] The purpose of the utility model is achieved through the following technical solutions: A deep hole processing machine tool comprises a workbench and a rotating clamping assembly and a drilling assembly mounted on the workbench, and a positioning assembly is provided on one side of the workbench close to the rotating clamping assembly;

[0008] The positioning assembly includes a circular slide rail fixedly installed on the workbench, a slider is slidably connected inside the circular slide rail, a fixed column is fixedly provided at the end of the slider away from the circular slide rail, a pressure plate is slidably connected inside the fixed column, a pressure rod is fixedly provided at the center of the pressure plate, a semicircular surface is provided at one end of the pressure rod, a controller is fixedly installed on the side of the fixed column away from the pressure plate, and a button is provided on the controller corresponding to the position of the pressure rod.

[0009] Preferably, a movable groove is provided on one side of the fixing column close to the pressure plate, and the pressure plate and the movable groove are connected by an elastic member.

[0010] By adopting the above technical solution, when the pressure plate is no longer subjected to pressure, the elastic force of the elastic member will cause the pressure plate to reset.

[0011] Preferably, a movable hole adapted to the button is provided at a position of the fixing column corresponding to the button.

[0012] By adopting the above technical solution, when the pressure rod retracts into the movable groove, the pressure rod will apply pressure to the button.

[0013] Preferably, a plurality of scale grooves are provided on the front side of the circular slide rail, and a pointer is fixedly provided on one side of the fixing column close to the scale grooves.

[0014] By adopting the above technical solution and using the pointer and the scale groove for comparison and reference, the staff can accurately control the position of the fixed column.

[0015] Preferably, a positioning screw is threadedly connected to a side of the sliding block away from the pointer.

[0016] By adopting the above technical solution, the slider can be limited by using the positioning screw.

[0017] Preferably, the controller is electrically connected to the rotary clamping assembly.

[0018] By adopting the above technical solution, the button can transmit the signal to the rotating clamping assembly through the controller. When the pressure rod is reset, the controller can control the rotating clamping assembly to shut down quickly.

[0019] Compared with the prior art, the utility model has the following advantages:

[0020] The deep hole processing machine tool, by setting a positioning component, can use the semicircular surface of the pressure rod to clamp in the hole, so as to avoid the deviation of the workpiece. At the same time, the controller can control the rotary clamping component to shut down quickly, effectively improving the control effect of the rotary clamping component on the workpiece, thereby improving the hole opening accuracy of the workpiece. On the other hand, by using the cooperation between the slider and the circular slide rail, the position of the fixed column can be adjusted according to the required hole spacing, so that the workpiece can be opened with a variety of control quantities on the device.

[0031] Additional aspects and advantages of the present invention will be further described below in conjunction with the accompanying drawings, and some will become apparent from the following description or be learned through practice of the present invention.

[0032] like Figure 1-6 As shown, a deep hole processing machine tool comprises a workbench 1 and a rotating clamping assembly 2 and a drilling assembly 3 mounted on the workbench 1. A positioning assembly 4 is provided on one side of the workbench 1 close to the rotating clamping assembly 2. The rotating clamping assembly 2 and the drilling assembly 3 in this embodiment are both well-known technologies in the technical field, so their specific structures and working principles are not described in detail;

[0033] The positioning assembly 4 includes a circular slide rail 401 fixedly mounted on the workbench 1, a slider 402 is slidably connected inside the circular slide rail 401, a fixed column 403 is fixedly arranged at one end of the slider 402 away from the circular slide rail 401, a plurality of scale grooves 4011 are arranged on the front side of the circular slide rail 401, a pointer 4033 is fixedly arranged on the side of the fixed column 403 close to the scale groove 4011, and a positioning screw 4021 is threadedly connected on the side of the slider 402 away from the pointer 4033. By utilizing the cooperation between the slider 402 and the circular slide rail 401, the slider 402 can drive the fixed column 403 to adjust the position, and at the same time By comparing the pointer 4033 with the scale groove 4011 for reference, the staff can accurately control the position of the fixed column 403. After the position adjustment is completed, the positioning screw 4021 can be used to limit the slider 402. The internal sliding connection of the fixed column 403 is provided with a pressure plate 404. The side of the fixed column 403 close to the pressure plate 404 is provided with a movable groove 4031. The pressure plate 404 and the movable groove 4031 are connected by an elastic member 4032. By using the cooperation between the pressure plate 404 and the elastic member 4032, when the pressure plate 404 is subjected to pressure, the pressure plate 404 will squeeze the elastic member 4032. 4031, and when the pressure plate 404 is no longer under pressure, the elastic force of the elastic member 4032 causes the pressure plate 404 to return to its original position. A pressure rod 405 is fixedly arranged at the center of the pressure plate 404, and a semicircular surface is arranged at one end of the pressure rod 405. When the workpiece contacts the semicircular surface of the pressure rod 405, the pressure rod 405 drives the pressure plate 404 to retract into the movable groove 4031. When the hole opened on the workpiece corresponds to the pressure rod 405, the pressure plate 404 drives the pressure rod 405 to pop out, so that the semicircular surface of the pressure rod 405 is used to get stuck in the hole, thereby preventing the workpiece from deviating. 03 A controller 406 is fixedly installed on the side away from the pressure plate 404. A button 407 is provided at the position of the controller 406 corresponding to the pressure rod 405. The controller 406 is electrically connected to the rotating clamping assembly 2. A movable hole matching the button 407 is opened at the position of the fixed column 403 corresponding to the button 407. When the pressure rod 405 retracts into the movable groove 4031, the pressure rod 405 applies pressure to the button 407, so that the button 407 transmits the signal to the rotating clamping assembly 2 through the controller 406. When the pressure rod 405 is reset, the controller 406 can control the rotating clamping assembly 2 to shut down quickly.

[0034] The working process is as follows:

[0035] S1, during processing, the workpiece is clamped by the rotating clamping assembly 2, and then a hole is drilled in the workpiece by the drilling assembly 3;

[0036] S2, after a hole is processed, the workpiece is controlled to rotate by rotating the clamping assembly 2;

[0037] S3. When the workpiece contacts the semicircular surface of the pressure rod 405, the pressure rod 405 drives the pressure plate 404 to squeeze the elastic member 4032 and retract it into the movable groove 4031. When the pressure rod 405 retracts into the movable groove 4031, the pressure rod 405 applies pressure to the button 407, so that the button 407 transmits a signal to the rotating clamping assembly 2 through the controller 406.

[0038] S4. When the hole already opened on the workpiece corresponds to the pressure rod 405, the pressure plate 404 will drive the pressure rod 405 to pop out, so that the semicircular surface of the pressure rod 405 is stuck in the hole, thereby preventing the workpiece from deflecting. Then the elastic force of the elastic member 4032 will cause the pressure plate 404 and the pressure rod 405 to reset, and then the controller 406 can control the rotating clamping assembly 2 to stop quickly, and then the drilling assembly 3 can be used to drill a hole in the workpiece again;

[0039] S5. By utilizing the cooperation between the slider 402 and the circular slide rail 401, the slider 402 can drive the fixed column 403 to adjust the position. At the same time, by using the pointer 4033 and the scale groove 4011 for comparison and reference, the staff can accurately control the position of the fixed column 403. After the position adjustment is completed, the positioning screw 4021 can be used to limit the slider 402, so that when in use, the position of the fixed column 403 can be adjusted according to the required hole spacing, so that the workpiece can open a variety of control quantities on the device.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
