Description

Technical Field

[0001] The utility model relates to the technical field of cylinder body processing, in particular to a processing device. Background Art

[0002] The straight hole in the engine cylinder block for assembling the cylinder liner is called the cylinder liner mounting hole, or cylinder hole for short. The countersunk hole near the top surface of the cylinder block is called the cylinder hole stop.

[0003] At present, the processing of cylinder bore stop is mostly completed by boring tool, and the specific process is as follows:

[0004] The controller controls the machine tool guide rail to drive the spindle to move once according to the set distance. The spindle drives the boring head to move along the axial direction of the cylinder body to form a cylinder hole. During this process, the boring cutter on the boring head cuts the hole wall of the cylinder hole to form a stop. After the preliminary processing of the stop is completed, the cylinder body is taken out and placed in a three-dimensional coordinate measuring machine. The depth of the stop is detected by the three-dimensional coordinate measuring machine. According to the measurement results, the user adjusts the secondary movement distance of the spindle and the boring head in the controller, so that the boring cutter continues to process the stop until the processing depth of the stop meets the processing requirements.

[0005] However, each time the depth of the stop is measured, the cylinder body needs to be taken out of the machine tool and sent to a three-dimensional coordinate measuring machine. After the measurement is completed, it is sent back to the machine tool for further processing. This will make the processing steps of the stop more complicated, and thus lead to low processing efficiency of the cylinder body stop. Utility Model Content

[0027] Please refer to Figures 1 to 3The utility model provides a processing device suitable for processing a workpiece 1 to be processed, the processing device comprising: a boring head 10, the boring head 10 is movably arranged to bore a mounting hole 12 inside the workpiece 1 to be processed, a cutting piece 11 is arranged on the circumferential outer side of the boring head 10, so that during the movement of the boring head 10, a recess 13 is cut out on the inner wall of the mounting hole 12 by the cutting piece 11, wherein the cutting edge 111 of the cutting piece 11 is inclined at a preset angle relative to the axial direction of the mounting hole 12, so that the recess 13 is recessed along the radial direction of the mounting hole 12; a detection piece 30 is arranged above the top wall 121 of the mounting hole 12, so as to detect the distance between the top wall 121 of the mounting hole 12 and the bottom of the detection piece 30 along the axial direction of the mounting hole 12, and the boring head 10 is controlled to move according to the distance detected by the detection piece 30 until the depth of the recess 13 along the axial direction of the mounting hole 12 reaches a preset depth.

[0028] The processing device of the utility model is suitable for processing a workpiece 1 to be processed. The processing device comprises a boring head 10 and a detection member 30. The processing device first performs rough processing on the workpiece 1 to be processed. The boring head 10 moves once to bore out the mounting hole 12. The cutting member 11 on the boring head 10 cuts out a recess 13 on the inner wall of the mounting hole 12. Then the detection member 30 detects the distance between the top wall 121 of the mounting hole 12 and the bottom of the detection member 30 along the axial direction of the mounting hole 12, and obtains the real-time depth of the recess 13 along the axial direction of the mounting hole 12 according to the distance detected by the detection member 30. Then the processing device performs fine processing on the workpiece 1 to be processed. The boring head 10 performs a second movement according to the real-time depth of the recess 13 until the real-time depth of the recess 13 reaches a preset depth. Among them, the secondary movement distance of the boring head 10 is equal to the difference between the preset depth and the real-time depth of the recess 13. The processing device of the present application uses the detection part 30 to replace the three-dimensional coordinate measuring machine to detect the real-time depth of the recess 13. It is no longer necessary to take out the workpiece 1 to be processed and put it into the three-dimensional coordinate measuring machine for measurement. The processing steps of the recess 13 are simplified, the processing efficiency of the recess 13 is improved, and the problem of low processing efficiency of the cylinder block stop in the prior art is solved.

[0029] Specifically, the workpiece 1 to be processed is a cylinder block, the mounting hole 12 is a cylinder hole, and the recess 13 is a stopper.

[0030] When implementing it, Figure 1 As shown in the left cutting piece 11, before the real-time depth of the recess 13 reaches the preset depth, the cutting edge 111 of the cutting piece 11 is inclined at 90° relative to the axial direction of the mounting hole 12, that is, the extending direction of the cutting edge 111 is perpendicular to the axial direction of the mounting hole 12, and the cutting edge 111 has a first edge extending along the axial direction of the mounting hole 12 and a second edge extending along the radial direction of the mounting hole 12, the first edge and the second edge are connected to each other, and the first edge and the second edge are respectively in contact with the side wall and the bottom wall of the recess 13. Figure 1As shown in the right cutting piece 11 , after the real-time depth of the recess 13 reaches the preset depth, the cutting edge 111 of the cutting piece 11 is inclined at 30° relative to the axial direction of the mounting hole 12 to form a chamfer on the recess 13 .

[0031] In specific implementation, the distance detected by the detection member 30 is d 检测 , the preset depth of the recess 13 is d 预设 The boring head 10 has a first end 17 and a second end which are arranged opposite to each other in the axial direction of the mounting hole 12. The first end 17 is arranged away from the workpiece 1 relative to the second end. The distance between the first end 17 and the second edge of the cutting edge 111 is d1. The distance between the first end 17 and the bottom of the detection member 30 before moving is d2. The real-time depth d of the recess 13 is 实时 =d1-d2-d 检测 , the secondary moving distance d of the boring head 10 移动 =d 预设 -d 实时 .

[0032] In this embodiment, if Figure 1 and Figure 2 As shown, there are multiple detection members 30, and the multiple detection members 30 are arranged above the top wall 121 of the mounting hole 12 at intervals along the circumferential direction of the mounting hole 12, so that each detection member 30 detects the distance between the top wall 121 directly below it and the bottom of the detection member 30; there are multiple cutting members 11, and the multiple cutting members 11 are arranged on the boring head 10 at intervals along the circumferential direction of the boring head 10, and the multiple cutting members 11 are arranged one-to-one correspondingly to the multiple detection members 30.

[0033] Specifically, each detection member 30 detects the distance between the top wall 121 directly below it and the bottom of the detection member 30, and then the distances detected by the multiple detection members 30 are averaged to obtain an average detection distance. The average detection distance is used to obtain the secondary movement distance of the boring head 10. The multiple detection members 30 ensure that the depth of the recess 13 of the same mounting hole 12 remains consistent along the circumferential direction of the mounting hole.

[0034] Specifically, Figure 2 As shown, there are two detection members 30, which are relatively arranged on both sides of the boring head 10 along the radial direction of the mounting hole, and there are two cutting members 11, which are relatively arranged on the boring head 10 along the radial direction of the mounting hole.

[0035] In this embodiment, if Figure 3 As shown, the detection member 30 includes a probe 40, which is arranged on the detection member 30. After the recess 13 is cut out of the mounting hole 12, the detection member 30 starts to move along the axial direction of the mounting hole 12 until the probe 40 abuts against the top wall 121 of the mounting hole 12, and the moving distance of the detection member 30 at this time is used as the distance detected by the detection member 30.

[0036] Specifically, the detection member 30 can measure the distance between the top wall 121 of the mounting hole 12 and the bottom of the detection member 30 along the axial direction of the mounting hole 12 by using the moving distance of the probe 40 , thereby ensuring the measurement reliability of the detection member 30 .

[0037] Specifically, the probe 40 extends along the axial direction of the mounting hole 12, and the lower end of the probe 40 protrudes from the bottom end surface of the detection member 30. The detection member 30 detects the distance between the top wall 121 and the lower end of the probe 40 along the axial direction of the mounting hole 12. When the detection member 30 moves to the point where the lower end of the probe 40 abuts against the top wall 121, the detection member 30 stops moving.

[0038] In a specific implementation, the distance between the first end 17 and the lower end of the probe 40 before moving is d2. Figure 2 As shown, at this time, the probe 40 of the detection member 30 has abutted against the top wall 121, and the distance between the first end 17 and the lower end of the probe 40 is d2+d 检测 .

[0039] In this embodiment, the processing device further includes a first driving member, and the detecting member 30 is connected to the first driving member so that the first driving member drives the detecting member 30 to move.

[0040] Specifically, the processing device also includes a machine tool 80, on which the boring head 10 and the detection member 30 are movably arranged, and the workpiece 1 to be processed is detachably mounted on the machine tool 80. The machine tool 80 is provided with a guide rail for guiding the boring head 10, and the guide rail extends along the axial direction of the mounting hole 12; a first driving member is arranged inside the machine tool 80 for driving the detection member 30 to move.

[0041] Optionally, the first driving member is a motor.

[0042] In this embodiment, the detection member 30 includes a detection body 41 and a connecting member 42 which are connected to each other. The detection body 41 is drivingly connected to the first driving member, and the probe 40 of the detection member 30 is arranged on the connecting member 42 .

[0043] Specifically, the detection body 41 is used to connect the detection member 30 and the first driving member, and the connecting member 42 is used to connect the probe 40 and the detection member 30, so that the first driving member can drive the detection member 30 to move and thus the probe 40 to move.

[0044] In this embodiment, if Figure 3As shown, the processing device also includes: a blowing pipe 50, which is arranged on one side of the detection part 30, and an air outlet 51 is formed at one end of the blowing pipe 50, and the air outlet 51 is arranged toward the top wall 121 of the mounting hole 12, so that before the detection part 30 moves, the air flow in the blowing pipe 50 flows through the air outlet 51 to the top wall 121 of the mounting hole 12 to clean the top wall 121 of the mounting hole 12.

[0045] Specifically, by blowing air toward the top wall 121 of the mounting hole 12 through the air blowing pipe 50, impurities such as iron filings remaining on the top wall 121 can be blown away, thereby ensuring that the surface of the top wall 121 is clean, and ensuring that the probe 40 of the detection component 30 can accurately abut against the top wall 121, thereby avoiding the probe 40 from abutting against impurities on the surface of the top wall 121, which would lead to inaccurate measurement results.

[0046] During the specific implementation, the boring head 10 moves once to bore out the mounting hole 12, and the cutting piece 11 on the boring head 10 cuts out a recess 13 on the inner wall of the mounting hole 12. Then the boring head 10 moves 2 mm in a direction away from the workpiece 1 to be processed, and then the blow pipe 50 blows toward the top wall 121 of the mounting hole 12. After the blow pipe 50 stops blowing, the detection piece 30 starts detection.

[0047] In this embodiment, there are a plurality of blowing pipes 50 , and the plurality of blowing pipes 50 are disposed in a one-to-one correspondence with the plurality of detection elements 30 .

[0048] Specifically, the plurality of blowing pipes 50 are respectively used to blow away the top wall 121 directly below, thereby preventing impurities from remaining on the top wall 121 , thereby ensuring the detection accuracy of the corresponding detection member 30 .

[0049] Specifically, Figure 2 As shown, there are two blowing pipes 50.

[0050] In this embodiment, if Figure 1 As shown, the processing device also includes a second driving member 52 and a driving shaft 53. The driving shaft 53 extends along the axial direction of the mounting hole 12. Both ends of the driving shaft 53 are respectively connected to the second driving member 52 and the boring head 10, so that the second driving member 52 drives the boring head 10 to move through the driving shaft 53.

[0051] Specifically, the second driving member 52 drives the boring head 10 to move via the driving shaft 53 to ensure that the boring head 10 can drive the cutting member 11 to move, so that the mounting hole 12 and the recess 13 are formed smoothly, wherein the second driving member 52 is a motor.

[0052] In this embodiment, if Figure 1 As shown, the processing device also includes a controller 43, which is communicatively connected to the second driving member 52, and the controller 43 is communicatively connected to the detection member 30, so that the controller 43 controls the second driving member 52 to work according to the detection result of the detection member 30.

[0053] Specifically, the controller 43 is a PLC (Programmable Logic Controller), and the processing device further includes a splitter 431 , a data processing unit 432 , an intermediate controller 435 and a numerical control system 433 .

[0054] During specific implementation, the detection results of multiple detection parts 30 are transported to the splitter 431, and then transmitted to the intermediate controller 435 by the splitter 431. The intermediate controller 435 summarizes the measurement results of the multiple detection parts 30 and transmits them to the data processing unit 432. The data processing unit 432 processes the measurement data fed back by the intermediate controller 435, takes the average value of the data measured by the multiple detection parts 30, and solves and calculates the measurement results and the dimensions required by the design drawings to obtain the continued movement distance of the second drive member 52, and then feeds back the continued movement distance to the controller 43. The controller 43 continues to transmit the data to the numerical control system 433. After the variable values ​​in the numerical control system 433 are updated, the data are transmitted back to the controller 43. At this time, the controller 43 controls the movement of the second drive member 52.

[0055] Specifically, a displacement sensor is disposed in the detection member 30 , the displacement sensor is connected to the probe 40 , and the displacement sensor is communicatively connected to the splitter 431 . The displacement sensor can convert the moving distance of the probe 40 into an electrical signal and transmit it to the splitter 431 .

[0056] It should be noted that the present application does not change the processing coordinate system set in the numerical control system 433, thereby ensuring the uniqueness and invariance of the coordinate system and not affecting subsequent processing at other positions.

[0057] In this embodiment, the processing device also includes a lubricating and cooling component 60, which is arranged in the boring head 10, and the nozzle of the lubricating and cooling component 60 is arranged toward the inner wall of the mounting hole 12, so that the liquid in the lubricating and cooling component 60 is sprayed toward the inner wall of the mounting hole 12 through the nozzle to lubricate and cool the inner wall of the mounting hole 12.

[0058] Specifically, when the boring head 10 reaches above the workpiece 1, the nozzle of the lubricating and cooling member 60 is opened to spray liquid to reduce thermal deformation of the workpiece 1 and the cutting member 11, maintain the hardness of the cutting member 11, and improve machining accuracy.

[0059] Specifically, the lubricating and cooling member 60 is a cutting fluid nozzle.

[0060] During specific implementation, the processing method of the processing device is as follows:

[0061] (1) When the workpiece to be processed is transported to the machine tool 80, the second driving member 52 drives the boring head 10 to move to the processing position above the workpiece to be processed through the driving shaft 53, the lubricating and cooling member 60 is turned on, and the boring head 10 rotates around its axis and moves into the workpiece to be processed 1, processes the mounting hole 12 and the recess 13, and performs rough processing on the recess 13;

[0062] (2) After the rough machining is completed, the boring head 10 moves 2 mm in a direction away from the workpiece 1 to be machined, and then the blow pipe 50 is opened to remove impurities such as iron filings on the top wall 121 of the mounting hole 12 during the rough machining process. After the cleaning is completed, the blow pipe 50 is closed, and then the probe 40 of the detection member 30 moves downward until it stops moving when it abuts against the top wall 121 of the mounting hole 12. The detection member 30 can use the moving distance of the probe 40 to measure the distance between the top wall 121 of the mounting hole 12 and the bottom of the detection member 30 along the axial direction of the mounting hole 12;

[0063] (3) The inspection result of the inspection member 30 is transported to the splitter 431, and then transmitted to the intermediate controller 435 by the splitter 431. The intermediate controller 435 summarizes the measurement results of multiple inspection members 30 and transmits them to the data processing unit 432; the data processing unit 432 processes the measurement data fed back by the intermediate controller 435, takes the average value of the data measured by multiple inspection members 30, and solves and calculates the measurement results and the required dimensions of the design drawings to obtain the continued movement distance of the second drive member 52, and then feeds back the continued movement distance to the controller 43, and the controller 43 continues to transmit the data to the numerical control system 433. After the variable values ​​in the numerical control system 433 are updated, the data are transmitted back to the controller 43. At this time, the controller 43 controls the second drive member 52 to move, and the second drive member 52 drives the boring head 10 and the cutting member 11 to continue to move, thereby completing the fine processing of the recess 13.

[0064] (4) After the fine machining of the concave portion 13 of a single workpiece 1 is completed, the boring head 10 is moved to the position to be machined of the workpiece, and the above actions are repeated to continue machining the remaining concave portions 13; wherein, after the machining of the concave portion 13 of the workpiece 1 is completed, other measuring sensors are used to measure the final depth of the concave portion 13 of the workpiece 1. If the final depth is qualified, the next workpiece is machined. If the final depth is unqualified, the equipment alarms and stops.

[0065] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0066] The processing device of the utility model is suitable for processing a workpiece 1 to be processed. The processing device comprises a boring head 10 and a detection member 30. The processing device first performs rough processing on the workpiece 1 to be processed. The boring head 10 moves once to bore out the mounting hole 12. The cutting member 11 on the boring head 10 cuts out a recess 13 on the inner wall of the mounting hole 12. Then the detection member 30 detects the distance between the top wall 121 of the mounting hole 12 and the bottom of the detection member 30 along the axial direction of the mounting hole 12, and obtains the real-time depth of the recess 13 along the axial direction of the mounting hole 12 according to the distance detected by the detection member 30. Then the processing device performs fine processing on the workpiece 1 to be processed. The boring head 10 performs a second movement according to the real-time depth of the recess 13 until the real-time depth of the recess 13 reaches a preset depth. Among them, the secondary movement distance of the boring head 10 is equal to the difference between the preset depth and the real-time depth of the recess 13. The processing device of the present application uses the detection part 30 to replace the three-dimensional coordinate measuring machine to detect the real-time depth of the recess 13. It is no longer necessary to take out the workpiece 1 to be processed and put it into the three-dimensional coordinate measuring machine for measurement. The processing steps of the recess 13 are simplified, the processing efficiency of the recess 13 is improved, and the problem of low processing efficiency of the cylinder block stop in the prior art is solved.

[0067] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0068] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.
