Description

Technical Field

[0001] The present invention relates to the field of machining equipment, and specifically to a production and processing equipment for elevator brake assemblies. Background Art

[0002] The elevator brake assembly is a core component to ensure the safe operation of the elevator. Its function is to brake the traction wheel through friction, so as to achieve the emergency braking or floor positioning of the elevator car. According to the braking principle and structural differences, elevator brakes are mainly divided into three categories: disc brakes, drum brakes and shoe brakes. Among them, the shoe brake realizes braking through the friction of the contact surface between the arc-shaped friction plate and the brake wheel.

[0003] Since the arc-shaped friction plate needs to be rigidly connected to the brake shoe base during the elevator braking process, and the arc-shaped friction plate is a consumable part that needs to be replaced, bolts arranged in a matrix on the arc-shaped friction plate are usually used to connect the arc-shaped friction plate and the brake shoe base together. In this way, high-precision and multi-position drilling of the arc-shaped friction plate has become a key link in the process of manufacturing the arc-shaped friction plate.

[0004] At present, for the drilling of the arc-shaped friction plate, the mainstream technology uses a multi-axis drilling machine to perform the drilling operation. Since the bolt holes are arranged in a matrix, the multi-axis drilling machine can only manually re-clamp the arc-shaped friction plate after completing the drilling of multiple bolt holes arranged longitudinally at the same position, so as to perform drilling on the next processing position, which is difficult to achieve rapid and continuous processing, reducing the processing efficiency, and it is difficult to ensure that the distance between the two bolt holes meets the requirements during the two clamps, resulting in low positional accuracy of the drilling.

[0005] In addition, when the existing fixture clamps the arc-shaped friction plate, the clamping adaptability is poor, it is difficult to quickly adjust the fixture to be compatible with arc-shaped friction plates of different curvatures, and when replacing the arc-shaped friction plate for clamping, the position of the fixture needs to be adjusted, making the operation more cumbersome and further reducing the processing efficiency. Summary of the Invention

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a production and processing equipment for elevator brake assemblies, including an operation table, on which a drilling assembly for performing one-time drilling on the holes in the longitudinal position of the arc-shaped friction plate is provided. In the middle of the upper side of the operation table, an arc-shaped substrate is fixedly installed. On the upper right part of the arc-shaped substrate, a clamping mechanism for quickly limiting arc-shaped friction plates with different curvatures is provided, and a positioning mechanism for quickly moving the arc-shaped friction plate to the drilling position is also provided on the arc-shaped substrate.

[0007] The clamping mechanism includes two symmetrically arranged sector-shaped adjusting plates that slide back and forth on the upper right part of the arc-shaped substrate. There are three shifting frames arranged at equal intervals along the circumferential direction of the arc-shaped substrate on the sector-shaped adjusting plates. The shifting frames slide radially along the arc-shaped substrate on the side of the sector-shaped adjusting plate close to the middle of the arc-shaped substrate. Two limiting wheels are arranged on the shifting frames through driving components. An adapting component for quickly adjusting the position of the shifting frames is also arranged on the sector-shaped adjusting plates.

[0008] The positioning mechanism includes a base block fixedly installed on the lower right part of the arc-shaped substrate. A pressing member for pressing against the arc-shaped friction plate is slidably arranged vertically on the upper right part of the arc-shaped substrate and between the two sector-shaped adjusting plates. A marking insertion rod that slides radially along the arc-shaped substrate is arranged in the middle of the arc-shaped substrate through a connecting component. The positioning mechanism also includes a fixed rod component.

[0009] The connecting component moves to the position of the fixed rod component, so that the connecting component drives the arc-shaped friction plate to quickly and accurately change the drilling position through the marking insertion rod.

[0010] Preferably, the driving component includes two sliding blocks symmetrically arranged inside the shifting frame. The sliding blocks are slidably connected to the shifting frame along the length direction of the corresponding shifting frame. The sliding blocks are rotatably connected to the limiting wheels at the corresponding positions. A first bidirectional screw rod that is in threaded connection with the two sliding blocks at the corresponding positions is rotatably arranged inside the shifting frame.

[0011] Preferably, the adapting component includes an adjusting screw rod rotatably arranged in the middle of the sector-shaped adjusting plate. The adjusting screw rod is in threaded connection with the shifting frame at the corresponding middle position. A second bidirectional screw rod that is in threaded connection with the sector-shaped adjusting plate is rotatably arranged on the upper right part of the arc-shaped substrate. The shifting frames in the middle of the same sector-shaped adjusting plate move synchronously with the shifting frames on both sides through a linkage part.

[0012] Preferably, the linkage part includes a linkage sliding plate that slides radially along the arc-shaped substrate on the sector-shaped adjusting plate. The linkage sliding plate is located between two adjacent shifting frames. Slide insertion guide rods are fixedly installed on both the left and right sides of the linkage sliding plate. The slide insertion guide rods are slidably connected to the corresponding shifting frames along the width direction thereof.

[0013] Preferably, the connecting component includes a shifting block that slides along the arc-shaped track of the arc-shaped substrate in the middle thereof. An electric push rod is fixedly installed at the lower part of the shifting block. The telescopic section of the electric push rod is fixedly connected to the marking insertion rod. The marking insertion rod has a stepped shaft structure with a gradually increasing diameter from top to bottom.

[0014] Preferably, the fixed rod assembly includes two symmetrically arranged limit buckles that slide back and forth on the base block. The left side of the limit buckle near the middle of the arc-shaped substrate is in the shape of a triangular plate. A tension spring is arranged between the two limit buckles. A limit U-shaped frame is slidably arranged along the arc track at the lower part of the arc-shaped substrate. A locking part for locking the displacement block is arranged on the limit U-shaped frame.

[0015] Preferably, the locking part includes two symmetrically arranged blocking plate members that slide back and forth on the limit U-shaped frame. The side of the blocking plate member close to the opening of the limit U-shaped frame is in an inclined surface structure. A spiral spring is arranged between the blocking plate member and the limit U-shaped frame.

[0016] Preferably, a locking stud is screwed on the limit U-shaped frame. A plurality of positioning holes for inserting the locking stud are equidistantly arranged along the circumferential direction at the lower part of the arc-shaped substrate.

[0017] Preferably, a U-shaped groove penetrating up and down is formed on the left side of the abutting member. A hydraulic rod is fixedly installed at the lower part of the base block. The telescopic section of the hydraulic rod is fixedly connected to the abutting member. Two symmetrically arranged auxiliary abutting plates are rotatably arranged on the left side of the abutting member.

[0018] Preferably, a synchronous pushing member is slidably arranged left and right at the lower part outside the abutting member. A driving screw rod threadedly connected to the synchronous pushing member is rotatably arranged on the right side of the abutting member. The left side of the synchronous pushing member is hinged to the corresponding auxiliary abutting plate through a connecting transmission plate.

[0019] The beneficial effects of the present invention are as follows: First, the present invention uses the limit wheels arranged on the three displacement frames to limit the position of the arc-shaped friction plate, so that the arc-shaped friction plate can move while being limited. Therefore, when reaming the bolt holes of the arc-shaped friction plate, there is no need to re-clamp the arc-shaped friction plate, which ensures the processing efficiency. And through the connecting component, the marking insertion rod can be driven to insert into the bolt holes that have been processed on the arc-shaped friction plate, so that the marking insertion rod can directly drive the arc-shaped friction plate to move its position, thereby quickly changing the position of the arc-shaped friction plate and further improving the processing efficiency.

[0020] Second, the present invention uses the fixed rod assembly to control the moving position of the marking insertion rod, so that the marking insertion rod can quickly drive the arc-shaped friction plate to move to the specified position, so that the arc-shaped friction plate accurately moves the corresponding distance when changing its position, ensuring the hole distance between the two bolt holes on the arc-shaped friction plate and improving the position accuracy of the drilling process. And the marking insertion rod can automatically adapt to bolt holes with different diameters, so that the moving distance of the marking insertion rod is equal to that of the arc-shaped friction plate, thereby ensuring the position accuracy of the processing of arc-shaped friction plates with bolt holes of different diameters.

[0021] III. The present invention adopts an adaptation component to quickly synchronously adjust the heights of three shifting frames on an arc-shaped substrate, enabling the shifting frames to drive the limiting wheels thereon to quickly clamp and limit arc-shaped friction plates with different curvatures. Since the limiting wheels are in rolling cooperation with the arc-shaped friction plates, the arc-shaped friction plates can move on the limiting wheels, and thus the arc-shaped friction plates can be quickly inserted and removed and replaced, further improving the processing efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] Embodiments of the present invention will be described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as a limitation of the present invention. For those without specific technical or conditions noted in the embodiments, the techniques or conditions described in the literature in the field or according to the product description are followed.

[0031] Referring to Figure 1 and Figure 2 , a production and processing device for an elevator brake assembly, including an operating table 1, on which a drilling assembly 5 for performing one-time drilling on the holes in the longitudinal position of the arc-shaped friction plate is provided. In the middle of the upper side of the operating table 1, an arc-shaped substrate 2 is fixedly installed. On the right part of the upper side of the arc-shaped substrate 2, a clamping mechanism 3 for quickly limiting the arc-shaped friction plates with different curvatures is provided. On the arc-shaped substrate 2, a positioning mechanism 4 for quickly moving the arc-shaped friction plate to the drilling position is also provided.

[0032] When drilling the arc-shaped friction plate is required, first, the arc-shaped friction plate is clamped and limited by the clamping mechanism 3. Subsequently, the drilling assembly 5 drills the bolt holes at one longitudinal position of the arc-shaped friction plate. Then, the positioning mechanism 4 drives the arc-shaped friction plate to quickly move a certain distance. Next, the drilling assembly 5 drills the bolt holes at another longitudinal position of the arc-shaped friction plate again.

[0033] Continuing to refer to Figure 1 and Figure 2 , the clamping mechanism 3 includes two symmetrically arranged sector-shaped adjusting plates 31 that slide back and forth on the right part of the upper side of the arc-shaped substrate 2. On the sector-shaped adjusting plate 31, three shifting frames 32 are arranged at equal intervals along the circumferential direction of the arc-shaped substrate 2. The shifting frames 32 slide along the radial direction of the arc-shaped substrate 2 on the side of the sector-shaped adjusting plate 31 close to the middle of the arc-shaped substrate 2. A driving assembly 33 is provided on the shifting frame 32.

[0034] Continuing to refer to Figure 1 and Figure 2 , the driving assembly 33 includes two symmetrically arranged sliding blocks 331 inside the shifting frame 32. The sliding blocks 331 are slidably connected to the shifting frame 32 along the length direction of the corresponding shifting frame 32. On the side of the sliding block 331 close to the middle of the arc-shaped substrate 2, a limiting wheel 34 is rotatably arranged. Inside the shifting frame 32, a first bidirectional screw 332 that is threadedly connected to the two sliding blocks 331 at the corresponding positions is rotatably arranged.

[0035] When drilling the arc-shaped friction plate is required, the operator manually rotates the first bidirectional screw 332 according to the thickness of the arc-shaped friction plate. The first bidirectional screw 332 drives the two sliding blocks 331 at the corresponding positions to approach each other. The sliding blocks 331 drive the limiting wheels 34 to approach each other synchronously, so that the minimum distance between the two limiting wheels 34 on the same shifting frame 32 is equal to the thickness of the arc-shaped friction plate.

[0036] Continue to refer to Figure 1 and Figure 2 The clamping mechanism 3 further includes an adaptation component 35 disposed on the sector-shaped adjusting plate 31 for quickly adjusting the position of the displacement frame 32. The adaptation component 35 includes an adjusting screw 351 rotatably disposed in the middle of the sector-shaped adjusting plate 31. The adjusting screw 351 is threadedly connected to the displacement frame 32 at the corresponding middle position. A second bidirectional screw 352 threadedly connected to the sector-shaped adjusting plate 31 is rotatably disposed at the upper right part of the arc-shaped substrate 2. The displacement frame 32 in the middle of the same sector-shaped adjusting plate 31 moves synchronously with the displacement frames 32 on both sides through a linkage part 353.

[0037] Continue to refer to Figure 1 and Figure 2 The linkage part 353 includes a linkage sliding plate 3531 slidably disposed on the sector-shaped adjusting plate 31 along the radial direction of the arc-shaped substrate 2. The linkage sliding plate 3531 is located between two adjacent displacement frames 32. Slide insertion guide rods 3532 are fixedly installed on both the left and right sides of the linkage sliding plate 3531. The slide insertion guide rods 3532 are slidably connected to the corresponding displacement frames 32 along the width direction thereof.

[0038] The operator manually rotates the adjusting screw 351 according to the curvature of the arc-shaped friction plate. The adjusting screw 351 drives the displacement frame 32 in the middle to move up and down. The displacement frame 32 in the middle drives the two slide insertion guide rods 3532 slidably connected thereto to drive the linkage sliding plates 3531 on both sides to move up and down synchronously. At the same time, the linkage sliding plate 3531 drives the displacement frame 32 at the corresponding position to move synchronously through the slide insertion guide rod 3532 on the other side thereof, so that the three displacement frames 32 on the same sector-shaped adjusting plate 31 move synchronously along the radial direction of the arc-shaped substrate 2.

[0039] When the three displacement frames 32 on the same sector-shaped adjusting plate 31 move upward along the radial direction of the arc-shaped substrate 2, the displacement frame 32 drives the limiting wheel 34 thereon to gradually move in the direction close to the axis of the arc-shaped substrate 2, so that the limiting wheels 34 move synchronously, so that the smaller the diameter of the arc-shaped friction plate that can be clamped and limited by the limiting wheels 34 on the three displacement frames 32, and further, the limiting wheels 34 can adapt to the arc-shaped friction plate with a larger curvature for limiting clamping. On the contrary, the limiting wheels 34 can adapt to the arc-shaped friction plate with a smaller curvature for limiting clamping.

[0040] The operator manually rotates the second bidirectional screw 352 according to the width of the arc-shaped friction plate, so that the second bidirectional screw 352 drives the sector-shaped adjusting plates 31 on both sides to move closer to each other synchronously. The sector-shaped adjusting plate 31 drives the limiting wheels 34 thereon to move synchronously, so that the limiting wheels 34 can clamp arc-shaped friction plates with different widths.

[0041] Refer to Figure 1 、Figure 2 , Figure 3 and Figure 4 , the positioning mechanism 4 includes a base block 41 fixedly installed on the lower right part of the arc-shaped substrate 2. A pressing member 42 for pressing against the arc-shaped friction plate is slidably arranged vertically on the upper right part of the arc-shaped substrate 2 and between two sector-shaped adjusting plates 31. A U-shaped groove 46 penetrating up and down is formed on the left side of the pressing member 42. A hydraulic rod 47 is fixedly installed on the lower part of the base block 41. The telescopic section of the hydraulic rod 47 is fixedly connected to the pressing member 42. Two auxiliary pressing plates 421 arranged symmetrically front and back are rotatably arranged on the left side of the pressing member 42.

[0042] Refer to Figure 2 and Figure 3 , a synchronous pushing member 422 is slidably arranged left and right on the lower part of the outer side of the pressing member 42. A driving screw 423 threadedly connected to the synchronous pushing member 422 is rotatably arranged on the right side of the pressing member 42. The left side of the synchronous pushing member 422 is hinged to the corresponding auxiliary pressing plate 421 through a connecting transmission plate 424.

[0043] After the position of the limiting wheel 34 is adjusted, the operator holds the arc-shaped friction plate and inserts it between the upper and lower corresponding limiting wheels 34, so that a drilling position on the arc-shaped friction plate is aligned with the lower part of the drill bit of the drilling assembly 5. Then, the telescopic section of the hydraulic rod 47 is extended, so that the hydraulic rod 47 drives the upper side of the pressing member 42 to abut against the lower part of the arc-shaped friction plate, so that the pressing member 42 locks the position of the arc-shaped friction plate.

[0044] It should be noted that in this embodiment, manual pre-measurement and marking can be carried out on the arc-shaped friction plate. Subsequently, the operator holds the arc-shaped friction plate and moves it to the position corresponding to the drill bit of the drilling assembly 5 marked thereon. If the distance error between the two drilling positions is too large, it may cause the arc-shaped friction plate to not be locked to the brake shoe matrix. However, if there is an error in the overall position of the two drilling positions on the arc-shaped friction plate, it does not affect connecting the arc-shaped friction plate to the brake shoe matrix. Therefore, it is not necessary to accurately align the initial drilling positions.

[0045] Subsequently, the operator manually rotates the driving screw 423. The driving screw 423 drives the synchronous pushing member 422. The synchronous pushing member 422 drives the auxiliary pressing plate 421 to rotate through the connecting transmission plate 424, so that the auxiliary pressing plate 421 rotates to abut against the arc-shaped friction plate, thereby increasing the abutting points on the arc-shaped friction plate, and further increasing the locking stability of the arc-shaped friction plate. Then, the drill bit drills the arc-shaped friction plate by moving the drilling assembly 5 downward.

[0046] Refer to Figure 2 , Figure 3 and Figure 4, a connecting component 43 is arranged in the middle of the arc-shaped substrate 2. The connecting component 43 includes a shifting block 431 that slides along the arc track of the arc-shaped substrate 2 in the middle. An electric push rod 432 is fixedly installed at the lower part of the shifting block 431. The upper end of the telescopic section of the electric push rod 432 is fixedly installed with a marking insertion rod 44. The marking insertion rod 44 has a stepped shaft structure with a gradually increasing diameter from top to bottom.

[0047] After the drilling assembly 5 finishes drilling a position of the arc-shaped friction plate, the drill bit is moved to the initial position through the drilling assembly 5. Subsequently, the telescopic section of the electric push rod 432 is extended to drive the marking insertion rod 44 to insert into the drilled bolt hole of the arc-shaped friction plate that has been processed. When the marking insertion rod 44 inserts into the bolt hole, due to the stepped shaft structure of the marking insertion rod 44 with a gradually increasing diameter from top to bottom, it can automatically adapt to the diameter of the bolt hole, so that the marking insertion rod 44 can completely fill the bolt hole, and further make the moving amount of the marking insertion rod 44 equal to the moving amount of the arc-shaped friction plate.

[0048] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the positioning mechanism 4 further includes a fixed rod assembly 45. The fixed rod assembly 45 includes two symmetrically arranged limit buckles 451 that slide back and forth on the base block 41. The left side of the limit buckle 451 near the middle of the arc-shaped substrate 2 is in a triangular plate structure. A tension spring is arranged between the two limit buckles 451.

[0049] In the initial state, the arc surface of the U-shaped groove 46 is coaxially arranged with the drill bit at the corresponding position of the upper drilling assembly 5. The right side surface of the shifting block 431 is attached to the left side surface of the base block 41. At the same time, the triangular plate structure of the limit buckle 451 is located on the left side surface of the shifting block 431, so that the inclined surface of the triangular plate structure of the limit buckle 451 abuts against the shifting block 431. At this time, the shifting block 431 drives the marking insertion rod 44 to be coaxially arranged with the arc surface of the U-shaped groove 46, and further enables the marking insertion rod 44 to insert into the bolt hole of the arc-shaped friction plate that has been processed.

[0050] Then, the telescopic section of the hydraulic rod 47 is contracted so that the abutting member 42 no longer clamps the arc-shaped friction plate. Then, the operator manually slides the shifting block 431 to the left, so that the shifting block 431 drives the arc-shaped friction plate to move synchronously through the marking insertion rod 44. When the shifting block 431 moves, it can push the limit buckle 451 to the side away from the middle of the arc-shaped substrate 2. When the shifting block 431 moves to the left side of the limit buckle 451, the tension spring drives the limit buckle 451 to move to the initial position.

[0051] Refer to Figure 3 , Figure 4 and Figure 6, a limiting U-shaped frame 452 is slidably arranged along the arc track at the lower part of the arc-shaped substrate 2. A locking part 453 for locking the shifting block 431 is arranged on the limiting U-shaped frame 452. The locking part 453 includes two symmetrically arranged baffle plates 4531 that slide back and forth on the limiting U-shaped frame 452. One side of the baffle plate 4531 close to the opening of the limiting U-shaped frame 452 is a bevel structure. The bevel of the baffle plate 4531 faces to the right. A helical spring is arranged between the baffle plate 4531 and the limiting U-shaped frame 452.

[0052] When the shifting block 431 moves into the interior of the limiting U-shaped frame 452, the shifting block 431 contacts the bevel surface of the baffle plate 4531, so that the baffle plate 4531 moves in a direction away from the middle of the arc-shaped substrate 2. When the shifting block 431 completely moves into the interior of the limiting U-shaped frame 452, the helical spring drives the baffle plate 4531 to move back to its original position by its own elastic force, so that the baffle plate 4531 blocks the shifting block 431, so that the shifting block 431 and the limiting U-shaped frame 452 are locked into a whole.

[0053] At the same time, the shifting block 431 drives the arc-shaped friction plate to move to the next drilling position through the marking insertion rod 44, so as to ensure the distance between the two bolt holes of the arc-shaped friction plate. Then, the telescopic section of the hydraulic rod 47 is extended, so that the abutting member 42 abuts and limits the arc-shaped friction plate again. Then, the arc-shaped friction plate is drilled again by the drilling assembly 5. After that, the position of the drilling assembly 5 is restored, and the telescopic section of the hydraulic rod 47 is contracted. Then, the arc-shaped friction plate is pulled out from the limiting wheel 34, and a new arc-shaped friction plate is inserted into the limiting wheel 34, so as to continuously drill the arc-shaped friction plate.

[0054] In order to drill arc-shaped friction plates with different hole pitches, the following structure is also designed in this embodiment. A locking stud 454 is helically connected to the limiting U-shaped frame 452. A plurality of positioning holes 455 for inserting the locking stud 454 are equidistantly arranged along the circumferential direction at the lower part of the arc-shaped substrate 2.

[0055] When it is necessary to drill arc-shaped friction plates with different hole pitches, the limiting U-shaped frame 452 is moved to a suitable position, and then the locking stud 454 is rotated and inserted into the positioning hole 455 at the corresponding position, so that the limiting U-shaped frame 452 and the arc-shaped substrate 2 are locked into a whole, thereby changing the moving distance of the shifting block 431, and further adjusting the moving distance of the arc-shaped friction plate.

[0056] When the present invention drills the arc friction plate, the following steps are further included: First step, the operator manually rotates the first bidirectional screw rod 332 according to the thickness of the arc friction plate to drive the two sliding blocks 331 at the corresponding positions to approach each other, so that the minimum distance between the two limiting wheels 34 on the same displacement frame 32 is equal to the thickness of the arc friction plate.

[0057] Second step, the operator manually rotates the adjusting screw rod 351 according to the curvature of the arc friction plate, so that the three displacement frames 32 on the same sector adjusting plate 31 synchronously move along the radial direction of the arc-shaped substrate 2, so that the limiting wheels 34 can adapt to the arc friction plate with a larger curvature for limiting clamping. On the contrary, the limiting wheels 34 can adapt to the arc friction plate with a smaller curvature for limiting clamping.

[0058] Third step, the operator manually rotates the second bidirectional screw rod 352 according to the width of the arc friction plate to drive the two sector adjusting plates 31 on both sides to approach each other synchronously. The sector adjusting plates 31 drive the limiting wheels 34 thereon to move synchronously, so that the limiting wheels 34 can clamp the arc friction plates with different widths.

[0059] Fourth step, the operator holds the arc friction plate and inserts it between the upper and lower corresponding limiting wheels 34, so that a drilled hole position on the arc friction plate is aligned with the lower part of the drill bit of the drilling assembly 5. Then, the telescopic section of the hydraulic rod 47 is extended, so that the abutting member 42 locks the position of the arc friction plate.

[0060] Fifth step, the operator manually rotates the driving screw rod 423 to drive the auxiliary abutting plate 421 to rotate, so that the auxiliary abutting plate 421 rotates to abut against the arc friction plate, thereby increasing the abutting points on the arc friction plate, and further increasing the locking stability of the arc friction plate. Then, the drill bit is moved downward by the drilling assembly 5 to drill the arc friction plate.

[0061] Sixth step, the drill bit is moved to the initial position by the drilling assembly 5. Then, the telescopic section of the electric push rod 432 is extended to drive the marking insertion rod 44 to insert into the drilled bolt hole of the arc friction plate that has been processed. Then, the telescopic section of the hydraulic rod 47 is contracted. Then, the operator manually slides the displacement block 431 to the left until it completely moves into the internal of the limiting C-shaped frame 452, so that the displacement block 431 drives the arc friction plate to move synchronously to the next drilling position through the marking insertion rod 44.

[0062] Seventh step, the arc friction plate is drilled by the drilling assembly 5. Then, the arc friction plate is pulled out from the limiting wheels 34. Then, a new arc friction plate is inserted into the limiting wheels 34 to facilitate continuous drilling of the arc friction plate.

[0063] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention, and still be covered by the protection scope of the present invention.
