Description

Technical Field

[0001] The invention relates to the technical field of drilling equipment, and in particular to a drilling equipment for automobile parts and a processing technology thereof. Background Art

[0002] In the automobile manufacturing process, many parts need to be drilled to install fasteners such as bolts, nuts, and pins, or to form fluid channels such as oil channels and air channels through drilling. Moreover, with the continuous development of automobile technology, the precision and performance requirements of automobile parts are getting higher and higher. Therefore, the quality and efficiency of drilling are also particularly important.

[0003] The Chinese patent application with publication number CN114734069A discloses a double-head multi-center distance automatic drilling machine, including a base, an L-shaped plate fixedly connected to the upper end of the base, and two positioning plates fixedly connected to the inner bottom of the L-shaped plate, one of the positioning plates is fixedly connected to a motor, and the output end of the motor is fixedly connected to a rotating rod, and the other end of the rotating rod is rotatably connected to the other positioning plate. Two first fixed blocks and two second fixed blocks are fixedly connected to the base, and screws threadedly connected to the two second fixed blocks are penetrated through the two second fixed blocks, and a drilling machine is fixedly connected to the opposite ends of the two screws. The above application document achieves simultaneous drilling of both ends of the workpiece by driving the two drilling machines to move relative to each other.

[0004] However, in the actual implementation of the above application documents, since the extrusion plate that clamps the workpiece moves from top to bottom and presses the workpiece against the base, and the height of the drilling machine is not adjustable, only holes can be drilled within a specific range of the workpiece, and when the workpiece is thin, the workpiece is easily squeezed and deformed; in addition, before drilling, the position where the hole needs to be drilled cannot be located, which can easily lead to inaccurate drilling position and reduce the qualified rate of the workpiece.

[0005] Therefore, this field needs a kind of automobile parts drilling equipment and its processing technology to solve the above-mentioned problem. Summary of the invention

[0020] Preferably, the limiting structure includes a limiting block 1 fixedly connected to the connecting rod and a limiting block 2 fixedly connected to the pressing cylinder. When drilling, the connecting rod moves relative to the pressing cylinder to a position where the limiting block 2 and the limiting block 1 do not interfere with each other, the positioning part 1 and the positioning part 2 enter the drill hole, and when the friction rod abuts against the part, the connecting rod drives the pressing cylinder and the positioning head to rotate through the cooperation of the limiting block 1 and the limiting block 2.

[0040] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0041] like Figures 1 to 7 As shown, a drilling device for automobile parts of the present invention includes a workbench 1 and a clamping assembly arranged on the workbench 1, wherein the clamping direction of the clamping assembly is defined as the left-right direction, the clamping assembly includes two groups of clamps symmetrically arranged in the left-right direction, each group of clamps includes two clamps symmetrically arranged in the front-back direction, the clamps 2 are slidably connected to the workbench 1 along the left-right direction, and a driving assembly for driving the two groups of clamps to move towards or away from each other is arranged at the bottom of the workbench 1.

[0042] The driving assembly includes a lead screw 21 and a motor 22 for driving the lead screw 21 to rotate. The motor 22 is fixedly installed on the workbench 1. The lead screw 21 is fixedly connected to the output end of the motor 22. The workbench 1 is provided with a through slot 11 for the clamp 2 to move. The two clamps 2 of each group of clamps extend to the bottom of the workbench 1 and are connected by a connecting plate 24. The lead screw 21 is provided with two threaded sections with opposite thread rotation directions. The connecting plates 24 of the two groups of clamps are respectively matched with the corresponding threaded sections. The motor 22 drives the lead screw 21 to rotate, and the lead screw 21 drives the two groups of clamps to clamp parts or cancel the clamping of parts through the threaded sections. The clamps 2 arranged symmetrically on the left and right can adapt to the clamping of various parts, and the clamping position and clamping height of the parts are adjustable, which can adapt to the drilling requirements of different positions, thereby improving the applicability of the present invention.

[0043] like Figure 1 , Figure 3 and Figure 4 As shown, two drilling assemblies are symmetrically arranged on the left and right sides of the clamping assembly, and the drilling assemblies include a mounting plate 3, a drill bit 4, and a positioning assembly. The mounting plate 3 is slidably connected to the workbench 1 in the left-right direction, and a driving member 1 for driving the mounting plate 3 to move left and right is installed on the workbench 1. As an example, the driving member 1 is an electric telescopic rod 31, which is fixedly installed on the workbench 1, and the driving end of the electric telescopic rod 31 is fixedly connected to the mounting plate 3. By setting two drilling assemblies, when processing thicker parts, holes can be drilled from both sides of the parts at the same time, thereby improving the drilling efficiency.

[0044] The mounting plate 3 is connected to the mounting plate 5 through an elastic member, and the elastic member includes a slide bar 32 and a spring 2 33. The slide bar 32 is fixedly connected to the mounting plate 3, and the mounting plate 5 is slidably connected to the slide bar 32 in the left-right direction. The spring 2 33 is arranged between the mounting plate 5 and the mounting plate 3, and is sleeved on the outer periphery of the slide bar 32. The mounting plate 5 is connected to a pressing cylinder 6, and an observation window 61 communicating with each other from top to bottom is provided on the pressing cylinder 6. The drill bit 4 is located in the pressing cylinder 6 and is coaxially arranged with the pressing cylinder 6. The mounting plate 3 is installed with a motor 1 30, and the output end of the motor 1 30 is fixedly connected with a connecting rod 34 penetrating the mounting plate 5, and the drill bit 4 is coaxially arranged with the connecting rod 34 and is fixedly connected.

[0045] The positioning assembly includes a positioning head 7 and a driving structure that drives the positioning head 7 to move in the front-back direction. The positioning head 7 is elastically connected to the pressing cylinder 6 in the left-right direction. When positioning, the positioning head 7 is located at one end of the pressing cylinder 6 close to the part, and the tip of the positioning head 7 is located on the central axis of the drill bit 4. By setting the positioning head 7, before drilling, the position on the part to be drilled is aligned with the positioning head 7, so that the drilling position and the drill bit 4 are aligned, the accuracy of the position drilled by the drill bit 4 is improved, and when adjusting the position of the part, the drill bit 4 will not be skewed due to the collision between the part and the drill bit 4, affecting the normal use of the drill bit 4 and the drilling quality. When drilling, the pressing cylinder 6 presses on the surface of the part to form a support around the drill hole, avoiding convex deformation around the drill hole during the drilling process, and improving the drilling quality and the qualified rate of parts.

[0046] A V-shaped groove 23 extending in the front-to-back direction is provided on one side of the clamping plate 2 for clamping the part, the opening of the V-shaped groove 23 faces the part, and the straight line where the tip of the V-shaped groove 23 is located intersects with the straight line where the central axis of the drill bit 4 is located. By providing the V-shaped groove 23, the clamping plate 2 can clamp cylindrical parts, further improving the applicability of the present invention.

[0047] like Figure 4 and Figure 6 As shown, the positioning head 7 includes a positioning portion 1 71 and a positioning portion 2 72 which are symmetrically arranged in the front and rear directions. When positioning, the positioning portion 1 71 and the positioning portion 2 72 are in contact with each other to form the tip of the positioning head 7. The positioning portion 1 71 and the positioning portion 2 72 are respectively fixedly connected with a friction rod 8 extending in the front and rear directions, and the friction rod 8 is perpendicular to the positioning portion 1 71 and the positioning portion 2 72. An avoidance groove 62 for avoiding the friction rod 8 and the positioning head 7 is provided on the pressing cylinder 6. A limiting structure is arranged between the connecting rod 34 and the pressing cylinder 6. When the positioning portion 1 71 and the positioning portion 2 72 enter the drilled hole and the friction rod 8 abuts against the part, the limiting structure limits the relative rotation of the connecting rod 34 and the pressing cylinder 6.

[0048] After drilling is completed, there may be burrs and debris on the edge of the drilled hole on the part, affecting the drilling quality. By placing the positioning part 1 71 and the positioning part 2 72 close to the inner wall of the drilled hole, placing the friction rod 8 close to the surface of the part, and driving the connecting rod 34 to drive the installation cylinder to rotate, the installation cylinder can drive the positioning part 1 71, the positioning part 2 72 and the friction rod 8 to rotate, the positioning part 1 71 and the positioning part 2 72 can grind and clean the burrs on the inner periphery of the drilled hole edge, and the friction rod 8 can grind and clean the burrs on the end of the drilled hole, thereby improving the drilling quality.

[0049] Mounting blocks 63 are symmetrically arranged on the front and rear sides of the pressing cylinder 6. The mounting block 63 is slidably connected to a connecting rod 64 along the left and right directions. A baffle 65 is fixedly connected to the outer periphery of the connecting rod 64. A spring 66 is arranged between the baffle 65 and the corresponding mounting block 63. One end of the connecting rod 64 facing away from the mounting block 63 is fixedly connected to the corresponding friction rod 8.

[0050] like Figures 3 to 6 As shown, the driving structure includes a guide plate 9 and a guide groove 90 provided on the guide plate 9. The guide plates 9 are symmetrically arranged at the front and rear sides of the pressing cylinder 6 and are fixedly connected to the pressing cylinder 6. The mounting plate 5 is fixedly connected to the mounting ring 52 through a fixing rod 51. The inner circumference of the mounting ring 52 is rotatably connected to a rotating ring 53. The guide plate 9 is fixedly connected to the rotating ring 53. The guide groove 90 includes an inclined portion 91 and a straight portion 92 which are connected to each other. The straight portion 92 extends in the left-right direction. The inclined portion 91 is inclined from an end away from the pressing cylinder 6 to an end close to the pressing cylinder 6 in a direction close to the parts. The connecting rod 64 is slidably connected to the guide plate 9 and the mounting block 63 respectively along the front-rear direction, and a guide column 67 is fixedly connected to the connecting rod 64, and the guide column 67 extends into the guide groove 90. When the guide column 67 is located at the inclined portion 91 close to one end of the pressing cylinder 6, the positioning portion 1 71 and the positioning portion 2 72 are in contact to form the tip of the positioning head 7. When the guide column 67 is located at the straight portion 92, a space for the drill bit 4 to pass through is formed between the positioning portion 1 71 and the positioning portion 2 72.

[0051] like Figure 5 and Figure 7 As shown, the limiting structure includes a limiting block 1 35 fixedly connected to the connecting rod 34 and a limiting block 2 68 fixedly connected to the pressing cylinder 6. When drilling, the connecting rod 34 moves relative to the pressing cylinder 6 to a position where the limiting block 2 68 and the limiting block 1 35 do not interfere with each other. When the connecting rod 34 drives the drill bit 4 to rotate, the pressing cylinder 6 presses on the surface of the part and remains motionless. Figure 6 and Figure 7 As shown, when the positioning part 1 71 and the positioning part 2 72 enter the drilled hole and the friction rod 8 abuts against the part, the connecting rod 34 drives the pressing cylinder 6 and the positioning head 7 to rotate through the cooperation of the limit block 1 35 and the limit block 2 68 to grind and clean the burrs on the drilled hole.

[0052] A processing technology of a drilling device for automobile parts, using the drilling device for automobile parts in the above embodiment, the processing technology of the drilling device for automobile parts includes the following steps:

[0053] Mark the locations where holes need to be drilled on the parts, and then clamp the parts on the clamping assembly;

[0054] The electric telescopic rod 31 is controlled to drive the mounting plate 3 to move toward the direction close to the part. The mounting plate 3 pushes the mounting plate 5 through the spring 66 to drive the pressing cylinder 6 and the positioning head 7 to move toward the direction close to the part until the tip of the positioning head 7 contacts the part.

[0055] Observe whether the tip of the positioning head 7 is aligned with the center of the mark on the part. If not, adjust the position of the part so that the center of the mark is aligned with the tip of the positioning head 7;

[0056] The electric telescopic rod 31 is controlled to continue to drive the mounting plate 3 to move in the direction close to the part. Since the positioning head 7 is pressed against the part and cannot move forward at this time, as the mounting plate 5 and the pressing cylinder 6 continue to move, the inclined portion 91 of the guide groove 90 drives the guide column 67 to drive the connecting rod 64 to move in the direction away from the pressing cylinder 6, and the connecting rod 64 drives the positioning portion 1 71 and the positioning portion 2 72 to move in the direction away from the drilling position to make way for the drill bit 4. As the electric telescopic rod 31 continues to be driven, the pressing cylinder 6 is pressed against the surface of the part. At this time, the pressing cylinder 6 and the mounting plate 5 cannot move forward. The mounting plate 3 drives the connecting rod 34 and the drill bit 4 to continue to approach the part. During the movement, the limit block 1 35 on the connecting rod 34 and the limit block 2 68 on the pressing cylinder 6 gradually lose contact;

[0057] Control motor 1 30 to drive connecting rod 34 to drive drill bit 4 to rotate and drill holes;

[0058] After the drilling is completed, the motor 1 30 is controlled to drive the connecting rod 34 to drive the drill bit 4 to rotate in the opposite direction and return to the initial position. At the same time, the electric telescopic rod 31 is controlled to drive the mounting plate 3 to drive the connecting rod 34 and the drill bit 4 to move in the direction away from the part. The end of the sliding rod 32 away from the mounting plate 3 is fixedly connected to the stopper 321. The mounting plate 3 drives the mounting plate 5 and the pressing cylinder 6 to move in the direction away from the part through the stopper 321. During the movement, the elastic force of the spring 2 33 and the cooperation of the guide groove 90 and the guide column 67 make the positioning part 1 71 and the positioning part 2 72 move in the direction close to each other until they are in contact.

[0059] The electric telescopic rod 31 is controlled again to drive the mounting plate 3 to drive the mounting disk 5 and the pressing cylinder 6 to move in the direction close to the part, so that the positioning part 1 71 and the positioning part 2 72 enter the drill hole, and the friction rod 8 abuts against the part. During the continuous movement of the pressing cylinder 6, the guide groove 90 drives the guide column 67 to drive the connecting rod 64 to move in the direction away from the pressing cylinder 6 until the positioning part 1 71 and the positioning part 2 72 are close to the inner wall of the drill hole. At this time, the control motor 1 30 drives the connecting rod 34 to drive the drill bit 4 to rotate, and the limit block 1 35 on the connecting rod 34 contacts and abuts against the limit block 2 68 on the pressing cylinder 6. The connecting rod 34 drives the pressing cylinder 6 to rotate through the cooperation of the limit block 1 35 and the limit block 2 68, and the pressing cylinder 6 drives the positioning part 1 71, the positioning part 2 72 and the friction rod 8 to grind and clean the burrs on the edge of the drill hole.
