Description

Technical Field

[0001] The invention belongs to the technical field of casting processing, and in particular relates to a flip-type deep hole processing device. Background Art

[0002] Deep hole processing refers to the processing process of holes with a ratio of hole length to hole diameter greater than 6. Generally, the depth-to-diameter ratio of deep holes in most cases is L / d≥100. Deep hole processing is widely used in the casting industry. At present, when drilling castings, the hole depth size is required to be larger, so the installation size of the drill bit must be guaranteed to be within a certain safety range to prevent the drill bit from breaking. Secondly, the tooling fixture is used to fix the casting in multiple directions;

[0003] When double-sided drilling is performed on a casting, the casting needs to be removed from the fixture, flipped over and then reinstalled. This operation greatly increases the workload and reduces processing efficiency. In addition, it is difficult to ensure that the fixed point does not shift during the flipping of the casting, causing the holes on both sides of the casting to not correspond, thereby affecting the deep hole processing accuracy. Summary of the invention

[0004] In order to overcome the above-mentioned defects, the present invention provides a flip-type deep hole processing device, which solves the problem that when performing double-sided drilling processing on a casting, the casting needs to be removed from the tooling fixture, and the casting needs to be flipped over and then reinstalled. Such operation greatly increases the workload and has low processing efficiency. In addition, it is difficult to ensure that the fixed point does not shift during the flipping process of the casting, resulting in the problem of mismatching of the holes on both sides of the casting.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, the casting is installed in the fixed seat, and the adjustment component is operated to position the casting by multiple pressing components and side stop components. Then, the drilling equipment is controlled to drill the casting, and through holes are opened on both sides of the fixed seat to prevent the fixed seat from interfering with the stroke of the drill bit in the drilling equipment. When the single-sided drilling process of the casting is completed, two multi-stage electric hydraulic rods are controlled to work, and the multi-stage electric hydraulic rods are extended to drive the slider to move in the slideway.

When the roller disengages from the concave hole during the movement, it can rotate 180 degrees around the middle of the bracket. At this time, the roller slides into the sliding hole, and the fixed seat drives the casting to rotate 180 degrees, thereby achieving the purpose of flipping the casting, so that the drilling equipment can drill the other side of the casting. Therefore, when double-sided drilling is performed on the casting, there is no need to remove the casting from the fixed seat, flip it over and then install it, which reduces the workload and improves the processing efficiency. Since there is no need to disassemble and assemble when double-sided drilling is performed on the casting, it is ensured that the fixing point of the casting does not occur, so that the drilled holes can accurately correspond to each other, and the deep hole processing accuracy is guaranteed.

[0018] 3. In the present invention, the handle is rotated in the opposite direction to drive the bidirectional screw to rotate, so that the two nuts can drive the two slides to move away from each other. As the distance between the two slides increases, the side stop assembly and the pressing assembly slowly separate from the casting, thereby releasing the locking state of the casting. Secondly, the force of the torsion spring will drive the connecting plate to rotate in the opposite direction, and the bottom of the connecting plate will squeeze the top block until the connecting plate returns to its original state and moves completely into the installation hole, which will not interfere with the taking and placing operation of the casting, thereby improving the convenience of operation.

DETAILED DESCRIPTION

[0027] The technical solution of the present application is further described in detail below in conjunction with specific implementation methods.

[0028] like Figure 1-7 As shown, the present invention provides a technical solution: a flip-type deep hole processing device, comprising a base 1, a fixing frame 2 is fixed on the base 1, a drilling device 3 is installed on the top of the inner wall of the fixing frame 2, an operation hole 4 is opened in front of the fixing frame 2, a fixing seat 5 is installed in the base 1, and a flip assembly 6 is installed on the front and rear sides of the fixing seat 5, respectively, and the flip assembly 6 includes an ear plate 601, the ear plate 601 is fixed on one side of the fixing seat 5, and the other side of the ear plate 601 is overlapped with a bracket 602, and the bracket 602 is connected to the fixing seat 5. 02 is an L-shaped design, and a rotating shaft 603 is installed through one side of the inner wall of the bracket 602, one end of the rotating shaft 603 is fixed to the fixed seat 5, and a movable block 604 is fixed to the other end of the rotating shaft 603, and a roller 605 is installed on one side of the movable block 604. The roller 605 is slidably connected in the sliding hole 8. Due to the provision of the sliding hole 8, the movable block 604 can drive the roller 605 to move in the sliding hole 8, and the roller 605 is limited by the sliding hole 8 to improve the movement stability of the roller 605;

[0029] A slider 606 is fixedly connected to the top of the inner wall of the bracket 602, and the slider 606 is slidably connected in the slide 7. One side of the slider 606 is fixedly connected to a multi-stage electric hydraulic rod 607, and the multi-stage electric hydraulic rod 607 is installed in the slide 7. By controlling the operation of the multi-stage electric hydraulic rod 607, the extension or shortening of the multi-stage electric hydraulic rod 607 will drive the slider 606 to move in the slide 7, thereby facilitating the slider 606 to drive the fixed seat 5 to move through the bracket 602 and the ear plate 601.

[0030] Slideways 7 are respectively provided on both sides of the base 1, and the flip assembly 6 is installed in the slideways 7. Slide holes 8 are respectively provided on both sides of the base 1. A concave hole 9 is provided at the bottom of the inner wall of the slide hole 8. The connection between the slide hole 8 and the concave hole 9 is designed in an arc shape. The top of the inner wall of the slide hole 8 is convex at the position corresponding to the concave hole 9, so that the roller 605 can drive the movable block 604 to deflect, and the movable block 604 drives the fixed seat 5 to rotate through the rotating shaft 603. When the roller 605 is separated from the concave hole 9 during the movement, it can rotate 180 degrees around the middle of the bracket 602, which is convenient for adjusting the angle of the fixed seat 5.

[0031] Through holes 10 are respectively provided on both sides of the interior of the fixing seat 5, and an adjusting component 11 is installed in the middle of the fixing seat 5. The two through holes 10 are located on both sides of the adjusting component 11. The adjusting component 11 includes a bidirectional screw rod 111, and bearings 112 are respectively installed on both sides of the outside of the bidirectional screw rod 111. The two bearings 112 are respectively clamped on both sides of the fixing seat 5, and one end of the bidirectional screw rod 111 passes through the fixing seat 5 and is fixed with a turning handle 113. The two sides of the outside of the bidirectional screw rod 111 are respectively threadedly connected with nuts 114, and the middle part of the slide seat 12 is clamped on the outside of the nut 114. The bidirectional screw rod 111 is driven to rotate by rotating the turning handle 113. During the rotation of the bidirectional screw rod 111, the two nuts 114 respectively drive the two slide seats 12 to approach or move away from each other, so that the slide seat 12 drives the side stop assembly 16 to approach or move away from the casting, so as to facilitate the fixed installation of castings of different specifications;

[0032] The two sides outside the adjustment component 11 are respectively installed with a slide seat 12, and the slide seat 12 is slidably connected in the two through holes 10. The side wall of the slide seat 12 is fixedly connected with a partition 13, and the top and bottom of the partition 13 are respectively overlapped with a side stop assembly 16, and the side stop assembly 16 includes a push plate 161, and the push plate 161 is overlapped on the partition 13. One side of the push plate 161 is provided with a plurality of anti-slip protrusions 162, and the other side of the push plate 161 is fixedly connected with two top blocks 163 and two limit rods 164, and one side of the top block 163 is overlapped with the pressing assembly 15. The position of the slide seat 12 corresponding to the limit rod 164 is provided with a limit hole 17, and the limit rod 164 is slidably connected in the limit hole 17. Because the limit rod 164 is provided, the limit rod 164 can be driven to slide in the limit hole 17 during the movement of the push plate 161, and the limit rod 164 is limited by the limit hole 17, so as to improve the stability of the horizontal movement of the push plate 161;

[0033] Two pressing assemblies 15 are overlapped on one side of the side stop assembly 16 close to the slide seat 12. The pressing assembly 15 includes a connecting plate 151. A connecting shaft 152 is fixed in the middle of the connecting plate 151. Both sides of the connecting shaft 152 are respectively sleeved with shaft sleeves 153. The shaft sleeves 153 are clamped on one side of the inner wall of the mounting hole 14. A pressing block 155 is fixedly connected to one side of the connecting plate 151. The connecting plate 151 drives the pressing block 155 on the top to deflect and contact with the top of the casting, and cooperates with the push plate 161 to squeeze the side of the casting, so that the side and top of the casting can be fixed in multiple directions, thereby improving the stability of the casting flipping and processing;

[0034] A torsion spring 154 is fixedly connected between the connecting plate 151 and the inner wall of the mounting hole 14, and the torsion spring 154 is sleeved on the outside of the connecting shaft 152. One side of the bottom of the connecting plate 151 overlaps with the side stop assembly 16; a mounting hole 14 is opened at a position corresponding to the pressing assembly 15 in the sliding seat 12, and the pressing assembly 15 is installed in the mounting hole 14. Because of the torsion spring 154, the force of the torsion spring 154 will drive the connecting plate 151 to rotate in the opposite direction, and the bottom of the connecting plate 151 will squeeze the top block 163, so that until the connecting plate 151 returns to its initial state and moves completely into the mounting hole 14, it will not interfere with the taking and placing operation of the casting, thereby facilitating the taking and placing of the casting.

[0035] The working principle of the present invention is:

[0036] The casting to be deep-hole processed is placed on the fixing seat 5 through the operating hole 4 in front of the fixing frame 2. The two sides of the casting can be embedded in the two through holes 10 on the fixing seat 5 and contact with the partition 13. The turning handle 113 drives the bidirectional screw rod 111 to rotate. During the rotation of the bidirectional screw rod 111, the two nuts 114 respectively drive the two slide seats 12 to approach each other, so that the slide seat 12 drives the side stop assembly 16 to approach the casting. When the push plate 161 in the side stop assembly 16 contacts the casting, the push plate 161 is compressed and drives the top block 163 to move, so that the top block 163 can push the connecting plate 151 in the pressing assembly 15, so that the connecting plate 151 can drive the connecting shaft 152 to rotate in the two shaft sleeves 153, and the connecting plate 151 drives the top pressure block 155 to deflect and contact with the top of the casting until the push plate 161 stops moving, thereby achieving the purpose of fixing the casting, and controlling the drilling equipment 3 to drill the casting;

[0037] When the single-sided drilling process of the casting is completed, the two multi-stage electric hydraulic rods 607 are controlled to work. The multi-stage electric hydraulic rods 607 are extended to drive the slider 606 to move in the slideway 7. The slider 606 drives the fixed seat 5 to move through the bracket 602 and the ear plate 601. The bracket 602 drives the movable block 604 to move through the rotating shaft 603. The movable block 604 drives the roller 605 to slide in the sliding hole 8. When the roller 605 slides into the concave hole 9, the top of the inner wall of the sliding hole 8 corresponds to the position of the concave hole 9, which is convex, so that the roller 605 can drive the movable block 604 to deflect. The movable block 604 drives the fixed seat 5 to rotate through the rotating shaft 603. When the roller 605 disengages from the concave hole 9 during the movement, it can rotate 180 degrees around the middle of the bracket 602. At this time, the roller 605 slides into the sliding hole 8, and the fixed seat 5 drives the casting to rotate 180 degrees, and the drilling device 3 can drill the other side of the casting.

[0038] When removing the casting after deep hole processing, the handle 113 is rotated in the opposite direction to drive the bidirectional screw rod 111 to rotate, so that the two nuts 114 can drive the two slide seats 12 to move away from each other. As the distance between the two slide seats 12 increases, the push plate 161 in the side stop assembly 16 and the pressure block 155 in the pressing assembly 15 slowly separate from the casting, and the locking state of the casting can be released. Secondly, the force of the torsion spring 154 will drive the connecting plate 151 to rotate in the opposite direction, and the bottom of the connecting plate 151 will squeeze the top block 163 until the connecting plate 151 returns to its initial state and moves completely into the mounting hole 14. Then, the casting is removed from the fixing seat 5.
