During processing, a drilling machine is required to process the plurality of inner holes 62. Before drilling, an auxiliary block 7 is manually inserted into the groove, and an indicating hole 71 for indicating the drilling position is formed on the auxiliary block 7 to facilitate the alignment operation of the operator.

[0003] During operation, when manually performing the alignment operation, the step of aligning the indicating hole with the drill bit of the drilling machine is difficult, which takes a long time for novices and affects the production efficiency. Summary of the Utility Model

[0004] The present application provides an automatic drilling device for the inner holes of brake calipers, which has the ability to automatically align the inner hole positions with the drill bits of the drilling machine.

[0005] The automatic drilling device for the inner holes of brake calipers provided by the present application adopts the following technical solutions:

[0006] An automatic drilling device for the inner holes of brake calipers includes a drilling machine with a drill bit and a working platform, and further includes a positioning table and a translation assembly. The translation assembly is used to move the positioning table on the working platform, and two positioning columns are arranged on the positioning table. When the brake caliper is assembled on the positioning table, the two positioning columns are inserted into the through holes at both ends of the brake caliper.

[0007] Through the above technical solutions, the function of the auxiliary block is replaced by the positioning table. The operator only needs to place the brake caliper on the positioning table, limit it through the positioning columns, and then let the translation assembly drive the positioning table to drive the brake caliper to move, finally realizing the automatic alignment of the inner hole positions with the drill bits of the drilling machine, avoiding the situation that it is difficult and time-consuming to manually align the inner hole positions with the drill bits of the drilling machine, reducing the labor burden and accelerating the working efficiency.

[0008] Preferably, the translation assembly includes a translation block, a left-right translation assembly, and a front-back translation assembly. The positioning table is fixed on the translation block, an activity groove is formed on the working platform, and the translation block slides in the activity groove. The left-right translation assembly is used to drive the translation block to move horizontally in the left-right direction, and the front-back translation assembly is used to drive the translation block to move horizontally in the front-back direction.

[0009] Through the above technical solution, the translation block, the left - right translation component, and the front - back translation component cooperate to enable the positioning table fixed on the translation block to move horizontally on the working platform, thereby realizing the automatic movement of the brake caliper and increasing the automation ability.

[0010] Preferably, the left - right translation component includes two first electric cylinders. The two first electric cylinders are arranged oppositely. The two first electric cylinders are located at the left and right horizontal ends of the translation block. The telescopic rod of the first electric cylinder faces the translation block, and the telescopic direction of the telescopic rod of the first electric cylinder is parallel to the horizontal left - right direction. The front - back translation component includes two second electric cylinders. The two second electric cylinders are arranged oppositely. The two second electric cylinders are located at the front and back horizontal ends of the translation block. The telescopic rod of the second electric cylinder faces the translation block, and the telescopic direction of the telescopic rod of the second electric cylinder is parallel to the horizontal front - back direction.

[0011] Through the above technical solution, the telescopic movement of the first electric cylinder can drive the translation block to move in the horizontal left - right direction, and the telescopic movement of the second electric cylinder can drive the translation block to move in the horizontal front - back direction. When the translation block approaches the target position, the first electric cylinder and the second electric cylinder stop telescopic movement, so as to keep the translation block stable at the target position.

[0012] Preferably, the translation component further includes moving parts. There is one moving part behind each of the first electric cylinder and the second electric cylinder. The moving part includes a lead screw and a driving source. The first electric cylinder and the second electric cylinder move on the lead screw, and the driving source is used to drive the lead screw to rotate to drive the first electric cylinder or the second electric cylinder to move along the length direction of the lead screw.

[0013] Through the above technical solution, the lead screw is used to drive the first electric cylinder and the second electric cylinder to move, reducing the situation that when the first electric cylinder or the second electric cylinder is working, the translation block moves out of the working range of the second electric cylinder under the action of the first electric cylinder, or vice versa. The setting of the lead screw enables the second electric cylinder to move together with the translation block when the first electric cylinder is working, or vice versa, avoiding the translation block moving out of the working range of the first electric cylinder or the second electric cylinder.

[0014] Preferably, a stud and a nut are further arranged on one side of the top end of the positioning column. The length direction of the stud is parallel to the length direction of the positioning column. When the positioning column is inserted into the through - hole, the stud passes through the through - hole, and the nut is threadedly connected to the stud passing through the through - hole, and the nut abuts against the top surface of the brake caliper.

[0015] Through the above technical solution, the brake caliper is abutted against the positioning column by the nut, thereby restricting the movement of the brake caliper along the length direction of the positioning column during the drilling process, and reducing the vibration generated during the drilling process, which may cause the brake caliper to vibrate and lead to deviation of the drilling position.

[0016] Preferably, an anti-fooling member is further provided on the positioning table, and the anti-fooling member is used to prompt the positional relationship between the positioning table and the brake caliper.

[0017] Through the above technical solution, an anti-fooling member is provided to avoid the deviation of the drilling position caused by the operator placing the brake caliper incorrectly.

[0018] Preferably, the anti-fooling member includes an anti-fooling post and a positioning ring. The anti-fooling post and the positioning ring are fixed on the positioning table. The positioning ring is located between two positioning posts. The anti-fooling post is located on the long side of one side of the positioning table, and the anti-fooling post is arranged close to the positioning ring.

[0019] Through the above technical solution, the setting of the positioning ring makes it more convenient for the operator to align the through hole and the positioning post. One end of the brake caliper has a convex shape facing outward. The anti-fooling post makes use of this point. The anti-fooling post close to the positioning ring will conflict with the convex part of the brake caliper facing outward, so that the brake caliper can only be placed on the positioning table in one posture.

[0020] The technical effects of the present invention are mainly reflected in the following aspects:

[0021] 1. By providing a positioning table and a translation assembly, the present invention uses the positioning table to replace the function of the auxiliary block, and then drives the positioning table by the translation assembly, thereby driving the brake caliper to move, and finally realizing the automatic alignment of the inner hole position and the drill bit of the drilling machine;

[0022] 2. By providing a movable member, the present invention avoids the translation block moving out of the working range of the first electric cylinder or the second electric cylinder during the translation process;

[0023] 3. By providing an anti-fooling member, the present invention avoids the deviation of the drilling position caused by the operator placing the brake caliper incorrectly. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0030] The following will further elaborate on the detailed implementation manners of the present utility model in conjunction with the attached Figures 1-5 drawings, so that the technical solutions of the present utility model are easier to understand and master.

[0031] An embodiment of the present application discloses an automatic device for drilling the inner hole of a brake caliper:

[0032] Referring to Figures 1-5 , an automatic device for drilling the inner hole of a brake caliper includes a drilling machine 1 with a drill bit 11 and a working platform 2, and also includes a positioning table 3 and a translation assembly 4. The translation assembly 4 is used to move the positioning table 3 on the working platform 2, and two positioning columns 31 are fixed on the positioning table 3. When the brake caliper 6 is assembled on the positioning table 3, the two positioning columns 31 are inserted into the through - holes 63 at both ends of the brake caliper 6. By using the positioning table 3 to replace the function of the auxiliary block 7, the operator only needs to place the brake caliper 6 on the positioning table 3, limit it through the positioning columns 31, and then let the translation assembly 4 drive the positioning table 3 to drive the brake caliper 6 to move, finally realizing the automatic alignment of the inner hole 62 hole position and the drill bit 11 of the drilling machine 1. It avoids the situation that it is difficult and time - consuming to manually align the inner hole 62 hole position and the drill bit 11 of the drilling machine 1, reduces the labor burden, and improves the work efficiency.

[0033] Referring to Figures 3-4 , the translation assembly 4 includes a translation block 41, a left - right translation assembly 42 and a front - rear translation assembly 43. The positioning table 3 is fixed on the translation block 41, and a movable groove 21 is provided on the working platform 2. The translation block 41 slides in the movable groove 21. The left - right translation assembly 42 is used to drive the translation block 41 to move horizontally in the left - right direction, and the front - rear translation assembly 43 is used to drive the translation block 41 to move horizontally in the front - rear direction. By the coordinated action of the translation block 41, the left - right translation assembly 42 and the front - rear translation assembly 43, the positioning table 3 fixed on the translation block 41 can move horizontally on the working platform 2, thus realizing the automatic movement of the brake caliper 6 and increasing the automation ability.

[0034] Referring to Figure 4, the left - right translation component 42 includes two first electric cylinders 421. The two first electric cylinders 421 are arranged oppositely. The two first electric cylinders 421 are located at the left and right horizontal ends of the translation block 41. The telescopic rod of the first electric cylinder 421 faces the translation block 41, and the telescopic direction of the telescopic rod of the first electric cylinder 421 is parallel to the left - right horizontal direction. The front - back translation component 43 includes two second electric cylinders 431. The two second electric cylinders 431 are arranged oppositely. The two second electric cylinders 431 are located at the front and back horizontal ends of the translation block 41. The telescopic rod of the second electric cylinder 431 faces the translation block 41, and the telescopic direction of the telescopic rod of the second electric cylinder 431 is parallel to the front - back horizontal direction.

[0035] The telescopic movement of the first electric cylinder 421 can drive the translation block 41 to move in the left - right horizontal direction, and the telescopic movement of the second electric cylinder 431 can drive the translation block 41 to move in the front - back horizontal direction. When the translation block 41 approaches the target position, the first electric cylinder 421 and the second electric cylinder 431 stop their telescopic movements, so as to keep the translation block 41 stable at the target position.

[0036] Refer to Figure 5 , the translation component 4 further includes a movable member 44. There is a movable member 44 arranged behind each of the first electric cylinder 421 and the second electric cylinder 431. The movable member 44 includes a lead screw 441 and a driving source 442. The first electric cylinder 421 and the second electric cylinder 431 move on the lead screw 441. The driving source 442 is used to drive the lead screw 441 to rotate to drive the first electric cylinder 421 or the second electric cylinder 431 to move along the length direction of the lead screw 441. The driving source 442 can be a motor 4421. Using the lead screw 441 to drive the first electric cylinder 421 and the second electric cylinder 431 to move reduces the situation that when the first electric cylinder 421 or the second electric cylinder 431 is working, the translation block 41 moves out of the working range of the second electric cylinder 431 under the action of the first electric cylinder 421, or vice versa. And the setting of the lead screw 441 enables the second electric cylinder 431 to move together with the translation block 41 when the first electric cylinder 421 is working, or vice versa, avoiding the translation block 41 moving out of the working range of the first electric cylinder 421 or the second electric cylinder 431.

[0037] Figure 5 Only the connection situation of one of the first electric cylinders 421 and the movable member 44 is shown, but the connection methods of the remaining first electric cylinders 421 and second electric cylinders 431 with the movable member 44 are Figure 5 the same, only the angles of the lead screws 441 are different. The lead screws 441 arranged at the rear sides of the first electric cylinder 421 and the second electric cylinder 431 form a square.

[0038] Refer to Figure 3, on one side of the top end of the positioning post 31, there are also a stud 32 and a nut 33. The stud 32 is fixed on the top end of the positioning post 31, and the length direction of the stud 32 is parallel to the length direction of the positioning post 31. When the positioning post 31 is inserted into the through hole 63, the stud 32 passes through the through hole 63, and the nut 33 is threadedly connected to the stud 32 passing through the through hole 63, and the nut 33 abuts against the top surface of the brake caliper 6. The nut 33 is used to abut the brake caliper 6 against the positioning post 31, thereby restricting the movement of the brake caliper 6 along the length direction of the positioning post 31 during the drilling process, reducing the vibration generated during the drilling process, and preventing the situation that the brake caliper 6 follows the vibration and causes deviation of the drilling position.

[0039] Refer to Figures 3-4 , a foolproof part 5 is also provided on the positioning table 3. The foolproof part 5 is used to prompt the positional relationship between the positioning table 3 and the brake caliper 6. The foolproof part 5 is used to avoid the situation that the drilling position is deviated due to the wrong placement of the brake caliper 6 by the operator.

[0040] The foolproof part 5 includes a foolproof post 51 and a positioning ring 52. The foolproof post 51 and the positioning ring 52 are fixed on the positioning table 3. The positioning ring 52 is located between the two positioning posts 31. The foolproof post 51 is located on the long side of one side of the positioning table 3 and is arranged close to the positioning ring 52. The setting of the positioning ring 52 makes it more convenient for the operator to align the through hole 63 and the positioning post 31; one end of the brake caliper 6 has a convex shape facing outwards. The foolproof post 51 makes use of this point. The foolproof post 51 close to the positioning ring 52 will conflict with the convex part of the brake caliper 6 facing outwards, so that the brake caliper 6 can only be placed on the positioning table 3 in one posture.

[0041] Of course, the above are only typical examples of the present invention. In addition, the present invention can also have many other specific implementation manners. Any technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection required by the present invention.
