Description

Technical Field

[0001] The invention relates to the field of machine tools, and in particular to an intelligent processing machine tool for producing micro-torque-changing cylinders. Background Art

[0002] Micro torque-converting cylinders are usually used in more precise fields. Cylinder workpieces will have deeper holes with smaller diameters during the machining process. When honing these holes, it is necessary to use a machining monitoring camera on the machine tool to monitor the machining conditions of the inner wall of the hole in real time to prevent machining defects such as cracks on the inner wall of the hole. However, existing monitoring cameras are usually installed on machine tools. When the honing head processes the holes on the cylinder, the camera cannot observe the machining conditions inside the holes, resulting in a large machining blind spot, which leads to the failure to detect machining defects in time and reduces production efficiency. Summary of the invention

[0003] In order to overcome the disadvantage that when a honing head is used to process the hole on the cylinder, the camera cannot observe the processing situation inside the hole, resulting in a large processing blind area and the inability to timely discover processing defects, the present invention provides an intelligent processing machine tool for the production of micro-torque variable cylinders.

[0005] Furthermore, it also includes a water pipe; a connecting groove is opened in the collar; a plurality of water pipes are fixedly connected to the collar, and the water pipes are connected with the connecting groove.

[0006] Furthermore, the water pipe is arranged to be inclined toward the axis of the honing knife.

[0007] Furthermore, it also includes a protective cover; the collar is fixedly connected with the protective cover, and the protective cover is located outside all water pipes.

[0008] Furthermore, the protective cover is arranged in a truncated cone shape.

[0009] Furthermore, it also includes an air pipe; the connecting ring is fixedly connected with a plurality of air pipes, and the air pipes are located on one side of the camera.

[0010] Furthermore, it also includes a fill light; a plurality of fill lights are fixedly connected to the connecting ring, and the fill lights are located on one side of the camera.

[0015] During honing, the present invention controls the external air pump to start and inputs gas into the air pipe. After the gas is ejected from the annularly distributed air pipe, an annular wind curtain is formed on the outside of the camera to block debris, thereby preventing the flying debris from hitting the camera and causing damage.

DETAILED DESCRIPTION

[0025] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0026] Example 1

[0027] An intelligent processing machine tool for producing micro-torque cylinders, such as Figure 1-Figure 7 As shown, it includes a machine tool body; the machine tool body consists of a bed 1, a sliding door 2, a rotating seat 3, a workbench 4, a machine head 5 and a honing tool 6; the bed 1 is slidably connected to the sliding door 2; the bed 1 is rotatably connected to the rotating seat 3; the rotating seat 3 is rotatably connected to the workbench 4; the bed 1 is slidably connected to the machine head 5; the rotating spindle on the machine head 5 is detachably connected to the honing tool 6; it also includes a collar 101, a connecting ring 102 and a camera 103; the machine head 5 is connected to the collar 101, and the honing tool 6 passes through the collar 101; the collar 101 is fixedly connected to the connecting ring 102; the connecting ring 102 is fixedly connected to a number of cameras 103.

[0028] It also includes a water pipe 104 ; a connecting groove 1011 is opened in the collar 101 ; at least six annularly distributed water pipes 104 are fixedly connected to the collar 101 , and the water pipes 104 are connected to the connecting groove 1011 .

[0029] The water pipe 104 is arranged to be inclined toward the axis of the honing knife 6 .

[0030] A protective cover 105 is also included; the collar 101 is fixedly connected with the protective cover 105 , and the protective cover 105 is located outside all the water pipes 104 .

[0031] The protective cover 105 is arranged in a truncated cone shape.

[0032] It also includes an air pipe 106 ; the connecting ring 102 is fixedly connected with a plurality of air pipes 106 , and the air pipes 106 are located on one side of the camera 103 .

[0033] A fill light 107 is also included; a plurality of fill lights 107 are fixedly connected to the connecting ring 102 , and the fill lights 107 are located on one side of the camera 103 .

[0034] The ring 101 is fixed with a plurality of bearings 108, and the rotating part of the bearing 108 is in contact with the honing tool 6, thereby improving the stability of the honing tool 6 during rotation and improving the honing accuracy.

[0035] When in use, first connect the pipeline of the external water pump to the water pipe 104, and then connect the pipeline of the external air pump to the air pipe 106. Then, manually push open the push door 2, clamp and position the workpiece 7 to be processed on the workbench 4, then close the push door 2, control the machine head 5 to make the honing knife 6 rotate slowly, and move vertically back and forth into the hole of the workpiece 7, and then hone the hole of the workpiece 7. Control the rotating seat 3 to rotate the workbench 4 and the workpiece 7 back and forth and horizontally to adjust. During the honing process, according to the specific situation of the workpiece 7 The radial feed rate, axial rotation speed and rotation speed of the honing tool 6 are adjusted to ensure the best honing effect. When the honing tool 6 hones the holes on the workpiece 7, the ring 101 is wrapped around the outside of the honing tool 6. A camera 103 is fixed at the end of the ring 101, and the camera 103 is placed close to the position of the tool head. The honing processing of the honing tool 6 in the hole is monitored and observed in real time through the camera 103, so that personnel can detect processing defects in time to avoid defects occurring after the processing is completed and produce defective products.

[0036] During the honing process, a small amount of coolant needs to be sprayed into the honing tool 6 regularly to cool and lubricate the honing tool 6 to ensure the stability of the honing process and the quality of the inner wall surface of the hole. Therefore, the external water pump is controlled to start, and the coolant is transported to the water pipe 104 through the pipeline, and then the coolant is vertically sprayed along the direction of the honing tool 6 through the water pipe 104 to the honing tool 6 in the hole and the inner wall of the hole of the workpiece 7, thereby cooling and lubricating the honing tool 6 and the workpiece 7. A small amount of coolant is used to accurately The honing tool 6 and the workpiece 7 are cooled and lubricated to ensure the honing effect. Since the micro cylinder is small in size, a large amount of coolant cannot be used. Therefore, it is necessary to spray coolant on the honing tool 6 intermittently to maintain the cooling effect. The water pipe 104 is connected to the connecting groove 1011, and the pipeline of the external water pump can be connected to the connecting groove 1011, so that the coolant flows through the connecting groove 1011 to the water pipe 104, and finally sprayed out from the water pipe 104. In the honing process, the coolant is regularly replenished as needed to improve the cooling and lubrication effect.

[0037] Since the water pipe 104 is inclined toward the axis of the honing tool 6 and the rotation speed of the honing tool 6 is relatively low, the coolant sprayed from the water pipe 104 first contacts the upper side of the honing tool 6, and then the coolant flows downward to the cutter head portion of the honing tool 6 under the action of its own gravity. Then, the coolant in the cutter head portion of the honing tool 6 is scattered outward to the inner wall of the hole of the workpiece 7 under the action of centrifugal force, thereby improving the cooling effect.

[0038] However, since the honing tool 6 is in a rotating state during honing, air flow is generated around the honing tool 6, which in turn causes the coolant sprayed from the nozzle of the water pipe 104 to splash. The water droplets splash onto the camera 103 at a close distance, obstructing the monitoring line of sight. Therefore, a protective cover 105 is provided to protect the coolant sprayed from the nozzle of the water pipe 104.

[0039] Since the protective cover 105 is arranged in a truncated cone shape, the coolant sprayed from the nozzle of the water pipe 104 is directed to the honing tool 6, reducing the degree of scattering of the coolant, so that the coolant can be concentrated on cooling and lubricating the surface of the honing tool 6, thereby improving the honing effect on the workpiece 7.

[0040] The honing tool 6 is in a rotating state during processing, so that the coolant in the hole and tiny metal debris generated by honing fly out. The flying coolant and metal debris can easily hit the camera 103, causing damage to the camera 103. Therefore, during honing, the external air pump is controlled to start and gas is input into the air pipe 106. After the gas is ejected from the annularly distributed air pipe 106, an annular wind curtain is formed on the outside of the camera 103 to block the debris, thereby preventing the flying debris from hitting the camera 103 and causing damage. When the honing tool 6 moves back and forth vertically, the gas ejected from the air pipe 106 blows onto the honing tool 6, which can also perform air cooling on the honing tool 6 to improve the cooling efficiency.

[0041] When the honing tool 6 is honing, the light in the hole of the workpiece 7 is weak, making it difficult for the camera 103 to observe. Therefore, by turning on the fill light 107, the light is accurately directed into the hole on the workpiece 7 along the direction of the honing tool 6 to perform fill light and improve the observation effect of the camera 103.

[0042] Example 2

[0043] On the basis of Example 1, Figure 6 As shown, it also includes a motor 201, a gear 202, a gear ring 203 and a hollow ring 204; the machine head 5 is provided with a slide groove 51; the machine head 5 is bolted to the motor 201; the output shaft of the motor 201 is fixedly connected to the gear 202; the machine head 5 is connected to the hollow ring 204, and the hollow ring 204 is located in the slide groove 51, and the honing tool 6 passes through the hollow ring 204; the hollow ring 204 is fixedly connected to the gear ring 203, and the gear ring 203 is meshed with the gear 202.

[0044] It also includes an electric push rod 205; the hollow ring 204 is slidably connected in the slide groove 51; the machine head 5 is bolted to the electric push rod 205, and the telescopic end of the electric push rod 205 is rotatably connected to the hollow ring 204.

[0045] During the processing, the honing tool 6 will swing to change the processing angle. Therefore, the camera 103 fixed on the ring 101 may still have a blind spot. Therefore, when the honing tool 6 swings, the motor 201 is controlled to start, and the output shaft of the motor 201 drives the gear 202 to rotate, and the gear 202 drives the gear ring 203 to rotate. The gear ring 203 causes the hollow ring 204 to drive the ring 101 to rotate, and then the ring 101 drives the connecting ring 102 and the camera 103 to rotate, thereby changing the angle of the camera 103. In this way, any one of the cameras 103 can be used to observe the processing status of the honing tool 6.

[0046] When the honing tool 6 is processing the hole of the workpiece 7, since the holes of the workpiece 7 are of different depths, the depth of the honing tool 6 entering the hole of the workpiece 7 is different, and it is necessary to adjust the depth of the ring 101 entering the hole so that the camera 103 can obtain a better observation angle. Therefore, the electric push rod 205 is controlled to drive the hollow ring 204 to move horizontally in the slide groove 51, and then the hollow ring 204 drives the ring 101, the connecting ring 102 and the camera 103 to move horizontally, thereby changing the depth of the camera 103 in the hole and improving the monitoring effect of the camera 103.

[0047] Example 3

[0048] On the basis of Example 2, Figure 5-Figure 7 As shown, a ring 206 is also included; the protective cover 105 is fixedly connected with the ring 206, and the ring 206 is in the shape of a flying saucer, and the air delivery pipe 106 is arranged to be inclined inwards.

[0049] When the honing tool 6 and the workpiece 7 are in a vertical processing state, the gas ejected from the gas pipe 106 is guided by the flying saucer-shaped ring 206 so that the airflow blowing onto the ring 206 spreads outward, thereby increasing the area of ​​the formed wind curtain and improving the protection effect on the camera 103.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
