Description

Technical Field

[0002] Workpiece end face processing drilling equipment is mainly used to perform drilling operations on the end face of the workpiece. These devices drill the required holes on the end face of the workpiece by rotating the tool and applying a certain feed force. According to the processing requirements, different types of drill bits can be selected, such as twist drills, center drills, etc., to meet the processing requirements of different hole diameters, hole depths and hole shapes.

[0003] Among the existing published technical documents, the Chinese patent publication number CN103464803A discloses a workpiece threaded hole processing equipment and method, which includes a drilling jig positioning device for positioning a three-hole positioning drilling jig, a horizontal drilling power head installed on one end of the frame structure bed facing the three-hole positioning drilling jig, a drilling tool quick-change chuck installed on one end of the horizontal drilling power head facing the three-hole positioning drilling jig, and a drilling tool installed on the drilling tool quick-change chuck. The method and equipment of the present invention can improve work efficiency and processing quality and reduce processing costs. However, the processing equipment still has the following defects when processing the end face of a workpiece.

[0004] When the processing equipment is drilling a hole on the end face of the workpiece, the drill bit needs to rotate at high speed and move toward the end face of the workpiece to drill.

However, the drill bit penetration size is difficult to accurately limit and protect, and the spacing between the two drill bits is also difficult to accurately limit and protect, which will cause the drilling depth to be too deep. Secondly, it will also cause the distance between the two holes to be too large or too small, which will ultimately lead to a significant decrease in the accuracy of the workpiece end face processing and a significant decrease in the quality of the workpiece end face processing.

[0015] Technical effects and advantages of the present invention:

[0016] 1. The present invention uses a depth limit protection mechanism, in which a driving motor drives a limit screw to rotate inside a support frame. The limit screw carries a sleeve block to move right under the action of thread transmission force, and the linkage frame plate drives the limit frame to move right. The limit frame moves right along the outer walls of the two milling heads, and the sleeve support block drives the pressure sensor to move right. The linkage bar carries the depth sensing block to move right. When the displacement distance sensed by the distance sensor is the same as the depth limit protection distance set by the controller, the driving motor is turned off through the controller, and the limit frame can realize precise depth limit protection operation for the two milling heads to avoid excessive drilling depth of the two milling heads, thereby greatly improving the accuracy of workpiece end surface processing and the workpiece end surface processing quality.

[0017] 2. The present invention adopts a depth limit sensing mechanism. When the two milling heads rotate into the end face of the workpiece, the sliding frame drives the supporting frame to move the limit screw to the left, and the limit screw drives the sleeve block to move the linkage frame plate to the left. When the depth sensing block is squeezed on the end face of the workpiece, the depth sensing block will be squeezed, and the depth sensing block drives the linkage bar to move right. The extrusion block can contact the end face of the workpiece, and the convex bar column moves right along the inner wall of the sleeve sliding block. The rubber block is squeezed on the pressure sensor. When the pressure value sensed by the pressure sensor is the same as the pressure value set by the controller, the electric cylinder is immediately closed through the controller, and the workpiece can realize precise limit sensing operation on the drilling depth of the two milling heads, and accurately realize high-quality processing of the end face of the workpiece.

[0018] 3. The present invention uses a spacing limit protection mechanism. The transmission motor drives the driving screw to rotate. The two transmission sleeves move away from each other under the action of the thread transmission force. The spacing distance sensor senses the distance of the spacing sensing block. When the distance value sensed by the spacing distance sensor is the same as the distance value set by the controller, the transmission motor drive is turned off by the controller. The two thread sleeves move away from each other under the action of the thread transmission force. When the sensing bar moves forward and is located on the sensing end of the proximity sensor, the adjustment motor is turned off by the controller. The distance between the two milling heads can be accurately limited and protected according to the specified distance through the two limit blocks, thereby avoiding the distance between the two milling heads from being adjusted too large or too small, greatly improving the accuracy of workpiece end face processing, and greatly improving the workpiece end face processing quality.

[0019] The interaction of the above multiple functions first enables the limit frame to achieve precise depth limit protection operation for the two milling heads, then enables the spacing distance sensor to achieve distance sensing for the spacing sensing block, the sensing bar moves forward and is located on the sensing end of the proximity sensor, and finally when the pressure value sensed by the pressure sensor is the same as the pressure value set by the controller, the electric cylinder is immediately shut down by the controller. In summary, the limit frame can achieve precise depth limit protection operation for the two milling heads, as well as precise limit protection operation for the distance between the two milling heads, to avoid the drilling depth from being too deep, and the distance between the two holes from being too large or too small, greatly improving the accuracy of workpiece end face processing, and greatly improving the workpiece end face processing quality.

[0036] In this embodiment, as shown in the attached Figure 7-10 As shown, the spacing limit protection mechanism includes a linkage screw 26 rotatably mounted on the inner wall of the slide frame 4; an adjusting motor 27 is fixedly mounted on one side of the slide frame 4, and the adjusting motor 27 is used to drive the linkage screw 26 to rotate, and the outer wall of the linkage screw 26 is threadedly connected to two threaded sleeves 28; a rotating motor 29 is fixedly mounted in front of each threaded sleeve 28, and the output end of the rotating motor 29 is coaxially connected to a milling head 30, and the upper surface of each rotating motor 29 is fixedly connected to a sensing bar 31, and the two sensing bars 31 are both slidably connected to the slide frame 4.

[0037] A support frame 32 is fixedly installed on the upper surface of the sliding frame 4, and a driving screw 33 is rotatably connected to the inner wall of the support frame 32. A transmission motor 34 is fixedly installed on one side of the support frame 32, and the transmission motor 34 is used to drive the driving screw 33 to rotate; two transmission sleeves 35 are threadedly connected to the outer wall of the driving screw 33, and the front of the two transmission sleeves 35 are fixedly connected to limit blocks 36, and a proximity sensor 37 is fixedly installed on the top of the limit blocks 36; a spacing distance sensor 38 is fixedly installed at the rear of one of the transmission sleeves 35, and a spacing sensing block 39 is provided on one side of the spacing distance sensor 38, and the spacing sensing block 39 is fixedly connected to the other transmission sleeve 35.

[0038] The two threads on the outer wall of the linkage screw 26 are opposite and symmetrically arranged, the outer walls of the two threaded sleeves 28 are both slidably connected to the sliding frame 4, the two transmission sleeves 35 are both slidably connected to the inner wall of the support frame 32, and the driving screw 33 drives the two threads on the outer wall to be opposite and symmetrically arranged; the upper surface of the spacing sensing block 39 and the upper surface of the spacing distance sensor 38 are in the same horizontal plane.

[0039] The working principle of the workpiece end surface processing equipment of the present invention is as follows:

[0040] Step 1: During installation, the processing platform 12 is supported by the base 16, the processing platform 12 supports the positioning seat 13, and the workpiece 14 is inserted into the outer wall of the positioning seat 13. There is a large placement space between the sleeve support plate 1 and the limit frame 11, so the workpiece 14 can be easily positioned on the outer wall of the positioning seat 13. The workpiece 14 is firmly positioned and supported, and the controller 15 starts the drive motor 17 at the same time.

[0041] Step 2: During the depth limit protection, the driving motor 17 drives the limit screw 6 to rotate inside the support frame 5, and the sliding frame 4 supports the support frame 5 to increase the stability of the support frame 5. The limit screw 6 carries the sleeve block 7 to move rightward under the action of the thread transmission force, and the sleeve block 7 moves rightward along the inner wall of the support frame 5. The sleeve block 7 drives the linkage frame plate 9 to move rightward, and the distance sensor 8 can provide support force through the support frame 5 to keep the distance sensor 8 in place.

[0042] The linkage frame plate 9 drives the limit frame 11 to move rightward, and the limit frame 11 moves rightward along the outer wall of the two milling heads 30. At the same time, the limit frame 11 drives the sleeve slider 24 to move the support column 23 to the rightward. The support column 23 carries the sleeve support block 22 to move rightward, and the sleeve support block 22 drives the pressure sensor 21 to move rightward. The pressure sensor 21 drives the rubber block 20 to move the convex column 19 to the rightward, and the convex column 19 drives the linkage bar 18 to move rightward. The linkage bar 18 carries the depth sensing block 10 to move rightward. The right side surface of the depth sensing block 10 and the left side surface of the milling head 30 are in the same vertical plane, so the depth sensing block 10 approaches the distance sensor 8. When the displacement distance sensed by the distance sensor 8 is the same as the depth limit protection distance set by the controller 15, the driving motor 17 is turned off by the controller 15, and the limit frame 11 can realize the precise depth limit protection operation for the two milling heads 30.

[0043] Step 3, during the spacing limit protection, the controller 15 starts the transmission motor 34, the transmission motor 34 drives the driving screw 33 to rotate, the driving screw 33 carries the two transmission sleeves 35 to move away under the action of the thread transmission force, the transmission sleeve 35 drives the limit block 36 to move forward, and the other transmission sleeve 35 drives the other limit block 36 to move backward, and the limit block 36 drives the proximity sensor 37 to move forward.

[0044] The transmission sleeve 35 can also drive the spacing distance sensor 38 to move forward, while another transmission sleeve 35 drives the spacing sensing block 39 to move backward, and the spacing distance sensor 38 realizes distance sensing for the spacing sensing block 39. When the distance value sensed by the spacing distance sensor 38 is the same as the distance value set by the controller 15, the transmission motor 34 is turned off by the controller 15. Then the controller 15 starts the adjustment motor 27, and the adjustment motor 27 drives the linkage screw 26 to rotate inside the slide frame 4. The linkage screw 26 carries the two thread sleeves 28 to move away from each other under the action of the thread transmission force, and the distance between the two thread sleeves 28 increases. The threaded sleeve 28 drives the rotating motor 29 to move forward, and the rotating motor 29 drives the milling head 30 to move forward. The rotating motor 29 also drives the sensing bar 31 to move forward. When the sensing bar 31 moves forward and is located on the sensing end of the proximity sensor 37, the adjusting motor 27 is turned off by the controller 15. In this way, the distance between the two milling heads 30 can be accurately limited by the two limit blocks 36 according to the specified distance to achieve protection operation, thereby avoiding the distance between the two milling heads 30 being adjusted too large or too small.

[0045] Step 4. During depth limit sensing, the electric cylinder 2 is supported by the socket support plate 1. The electric cylinder 2 pushes the push plate 3 to move left. The push plate 3 pushes the slide frame 4 to move left. The slide frame 4 drives the linkage screw 26 to make the two threaded sleeves 28 move left synchronously. The two threaded sleeves 28 respectively carry the two rotating motors 29 to move left. The controller 15 starts the two rotating motors 29. The two rotating motors 29 respectively drive the two milling heads 30 to rotate. The two milling heads 30 rotate at high speed inside the limit frame 11. The rotating motor 29 drives the milling head 30 to move left. The two milling heads 30 rotate into the end face of the workpiece 14 to realize the double-point drilling operation.

[0046] At the same time, the sliding frame 4 drives the supporting frame 5 to move the limiting screw 6 to the left, the limiting screw 6 drives the sleeve block 7 to move the linkage frame plate 9 to the left, the linkage frame plate 9 carries the limiting frame 11 to move to the left, when the depth sensing block 10 is squeezed on the end face of the workpiece 14, the depth sensing block 10 will be squeezed, the depth sensing block 10 drives the linkage bar 18 to move right, the linkage bar 18 drives the convex bar column 19 to move right, and the convex bar column 19 moves right along the inner wall of the sleeve sliding block 24. At the same time, the extrusion block 25 can contact the end face of the workpiece 14, and the extrusion block 25 moves to the right after generating an extrusion force. The extrusion block 25 carries the convex column 19 to move to the right, and the convex column 19 moves to the right along the inner wall of the sleeve slider 24. At the same time, the convex column 19 drives the rubber block 20 to move right and extrude. The rubber block 20 is squeezed on the pressure sensor 21, and the support column 23 is supported by the sleeve slider 24. The support column 23 supports the sleeve support block 22, and the sleeve support block 22 supports the pressure sensor 21. When the pressure value sensed by the pressure sensor 21 is the same as the pressure value set by the controller 15, the electric cylinder 2 is immediately closed by the controller 15 to prevent the electric cylinder 2 from continuing to push. At the same time, the left side of the limit frame 11 can be attached to the right side of the workpiece 14, and the workpiece 14 can realize precise limit protection operation on the drilling depth of the two milling heads 30.
