Description

Technical Field

[0001] The utility model relates to the technical field of bearing seat processing, in particular to a bearing seat processing drilling machine. Background Art

[0002] The bearing seat is a very critical component in the mechanical device. It is used to fix the bearing, bear various loads, and ensure that the bearing can operate normally. In the production process of the bearing seat, drilling is a key processing process. However, the existing bearing seat processing drilling machine requires the operator to use a measuring tool to mark the exact position of the fixing hole on the fixing plate before drilling. When the position of the fixing hole is not accurately marked, the position of the drilled fixing hole will not meet the size requirements, which will cause the bearing seat to be scrapped or reworked, increasing the cost investment.

[0003] In order to address the above problems, a Chinese patent with the existing announcement number CN218800668U proposes a bearing seat processing drilling machine, which is configured by sleeve-connecting the bearing seat body onto the shaft, and then rotating the threaded rod to make the pressure plate abut against the bearing seat body and the fixed plate, so that the bearing seat body and the fixed plate are positioned on the support plate, and then starting the drilling machine body and moving the drill bit downward through the feed handle, so that a accurately positioned fixing hole can be drilled on the fixed plate.

[0004] However, although the above-mentioned bearing seat processing drilling machine can position the bearing seat body by adjusting the threaded rod to push the pressure plate and the support plate to facilitate the drilling operation, when drilling holes on both sides of the bearing group body, the bearing seat processing drilling machine needs to adjust the pressure plate through the threaded rod multiple times and then exchange the position of the bearing seat body, which causes the problem of low drilling efficiency of the bearing seat. Therefore, the utility model provides a bearing seat processing drilling machine to meet the needs. Utility Model Content

[0005] The utility model aims to solve the problems existing in the above-mentioned background technology and proposes a bearing seat processing drilling machine.

[0006] The technical problem to be solved by the utility model is to provide a bearing seat processing drilling machine to solve the problem that when drilling holes on both sides of the bearing group body, the existing bearing seat processing drilling machine needs to adjust the pressure plate through the threaded rod for many times and then replace the position of the bearing seat body, thereby resulting in low drilling efficiency of the bearing seat.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] A bearing seat processing drilling machine, comprising:

[0009] A base, a back plate is provided on the top of which a positioning rod is provided, a support plate is fixedly connected to the base, a pull rod is movably provided on the support plate, the pull rod is provided with a pressure plate arranged opposite to the positioning rod, a first spring is sleeved on the pull rod, and the first spring is located between the pressure plate and the support plate;

[0010] A support seat is arranged on the base, a lifting mechanism is arranged on the support seat, a rotating mechanism is arranged at the bottom of the lifting mechanism, a Z-shaped rod is arranged at the bottom of the rotating mechanism, and a drilling mechanism is arranged at the bottom of the Z-shaped rod.

[0011] Preferably, two clamping plates are provided on the back plate to support and slide relative to the positioning rod, one end of the clamping plate facing away from the positioning rod is fixedly connected to a movable rod, and a fixing plate is fixedly connected to the base, and one end of the movable rod away from the clamping plate passes through and is movably arranged on the fixing plate, and a second spring is sleeved on the movable rod, and the second spring is located between the clamping plate and the fixing plate.

[0012] Preferably, the fixing plate is penetrated by a through hole through which the movable rod can move.

[0013] Preferably, a side of the clamping plate close to the supporting plate has a guiding end surface inclined toward the positioning rod.

[0014] Preferably, a sliding block is fixedly connected to the clamping plate, and a sliding groove for the sliding block to slide is provided on the back plate.

[0015] Preferably, one end of the pressure plate facing away from the pull rod is fixedly connected to a rubber pad, protrusions are evenly distributed on the rubber pad, and a through groove is penetrated by the base facing the drilling mechanism.

[0016] Compared with the prior art, the utility model has at least the following beneficial effects:

[0017] In the above scheme, a Z-shaped rod is set up, the bearing seat body is pressed against the back plate through the pressure plate, and then the direction of the drilling mechanism is adjusted by the cooperation of the rotating mechanism and the Z-shaped rod. The overall operation is simple and convenient, which improves the efficiency of drilling holes on the bearing seat body and avoids multiple adjustments of the pressure plate to disassemble and reposition the bearing seat body.

[0018] In the above scheme, a clamping plate and a second spring are provided, and the first spring drives the pressure plate to push the bearing seat body toward the positioning rod. At this time, the bearing seat body squeezes the two clamping plates to move relatively away from each other, so that the clamping plate squeezes the second spring. Therefore, when the bearing seat body is sleeved on the positioning rod, the bearing seat body is clamped and fixed by the clamping plate and the pressure plate at the same time, thereby improving the overall stability of the bearing seat body.

[0019] In the above scheme, by providing rubber pads and protrusions, the rubber pads can provide buffering when the pressure plate contacts the bearing seat body, thereby improving the protection of the bearing seat body. The protrusions can increase the friction between the bearing seat body and the pressure plate, thereby preventing the bearing seat body from sliding. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] like Figures 1 to 6As shown, an embodiment of the utility model provides a bearing seat processing drilling machine, including a base 2, a back plate 6 is provided on the top of which, a positioning rod 18 is provided on the back plate 6, a support plate 10 is fixedly connected to the base 2, a pull rod 8 is movably provided on the support plate 10, the pull rod 8 is provided with a pressure plate 13 arranged opposite to the positioning rod 18, a first spring 11 is sleeved on the pull rod 8, and the first spring 11 is located between the pressure plate 13 and the support plate 10, a support seat 1, which is arranged on the base 2, a lifting mechanism 3 is provided on the support seat 1, a rotating mechanism 4 is provided at the bottom of the lifting mechanism 3, a Z-shaped rod 5 is provided at the bottom of the rotating mechanism 4, and a drilling mechanism 23 is provided at the bottom of the Z-shaped rod 5.

[0030] Specifically, by pulling the pull rod 8 to move away from the positioning rod 18, the pull rod 8 drives the pressure plate 13 to squeeze the first spring 11, and then the bearing seat body 9 is sleeved on the positioning rod 18. At this time, the pull rod 8 is released, and the pressure plate 13 is positioned on the bearing seat body 9 under the elastic force of the first spring 11, and then the drilling mechanism 23 is driven by the lifting mechanism 3 to drill a hole on one side of the bearing seat body 9. When it is necessary to drill a hole on the other side of the bearing seat body 9, it is only necessary to drive the drilling mechanism 23 to rise by the lifting mechanism 3, and then adjust the direction of the drilling mechanism 23 by the rotating mechanism 4 to achieve the direction adjustment of the drilling mechanism 23. The overall operation is simple and convenient, which improves the efficiency of drilling holes on the bearing seat body 9 and avoids multiple adjustments of the pressure plate 13 to disassemble and replace the position of the bearing seat body 9. This solves the problem that when drilling holes on both sides of the bearing group body on the existing bearing seat processing drilling machine, it is necessary to adjust the pressure plate through the threaded rod multiple times and then replace the position of the bearing seat body, thereby causing low drilling efficiency of the bearing seat.

[0031] It should be noted that the line connection and installation method of the drilling mechanism 23, the rotating mechanism 4 and the lifting mechanism 3 are existing technologies. The lifting mechanism 3 can be an electric push rod, a screw lift, etc. The rotating mechanism 4 can drive the Z-shaped rod 5 to rotate 180°, thereby realizing the symmetrical exchange of the position of the drilling mechanism 23.

[0032] like Figures 1 to 5As shown, in this embodiment, two clamping plates 12 are provided on the back plate 6 to support and slide relative to the positioning rod 18, and the end of the clamping plate 12 away from the positioning rod 18 is fixedly connected to a movable rod 17, and the base 2 is fixedly connected to a fixing plate 7, and the end of the movable rod 17 away from the clamping plate 12 passes through and is movably arranged on the fixing plate 7, and a second spring 14 is sleeved on the movable rod 17, and the second spring 14 is located between the clamping plate 12 and the fixing plate 7, and a through hole 15 is penetrated on the fixing plate 7 for the movable rod 17 to move. The side of the clamping plate 12 close to the supporting plate 10 has a guiding end surface 22 inclined in the direction of the positioning rod 18, and a sliding block 24 is fixedly connected to the clamping plate 12, and a sliding groove 16 for the sliding block 24 to slide is provided on the back plate 6. Specifically, by placing the bearing seat body 9 It is placed on the base 2 at the front end of the two clamping plates 12. At this time, the through hole 15 of the bearing seat body 9 is arranged opposite to the positioning rod 18. Then, by loosening the pull rod 8, the first spring 11 drives the pressure plate 13 to push the bearing seat body 9 toward the positioning rod 18. At this time, the bearing seat body 9 squeezes the two clamping plates 12 to move relatively away from each other, so that the clamping plate 12 squeezes the second spring 14. Therefore, when the bearing seat body 9 is sleeved on the positioning rod 18, the bearing seat body 9 is clamped and fixed by the clamping plate 12 and the pressure plate at the same time, thereby improving the overall stability of the bearing seat body 9. It should be noted that the length of the pressure plate 13 is smaller than the length of the bearing seat body 9 to avoid conflict between the pressure plate 13 and the clamping plate 12. At the same time, the elastic force of the first spring 11 is greater than the second spring 14.

[0033] like Figure 6 As shown, in the present embodiment, the end of the pressure plate facing away from the pull rod 8 is fixedly connected with a rubber pad 20, and protrusions 21 are evenly distributed on the rubber pad 20. The base 2 is provided with a through groove 19 facing the drilling mechanism 23. Specifically, the rubber pad 20 can provide buffering when the pressure plate 13 contacts the bearing seat body 9, thereby improving the protection of the bearing seat body 9. The protrusion 21 can increase the friction between the bearing seat body 9 and the pressure plate 13, thereby preventing the bearing seat body 9 from sliding.

[0034] Working principle:

[0035] By pulling the pull rod 8 to move away from the positioning rod 18, the pull rod 8 drives the pressure plate 13 to squeeze the first spring 11, and then the bearing seat body 9 is placed on the base 2 at the front end of the two clamping plates 12. At this time, the through hole 15 of the bearing seat body 9 is arranged opposite to the positioning rod 18, and then by loosening the pull rod 8, the first spring 11 drives the pressure plate 13 to push the bearing seat body 9 to move toward the positioning rod 18. At this time, the bearing seat body 9 squeezes the two clamping plates 12 to move away from each other, so that the clamping plate 12 squeezes the second spring 14. Therefore, when the bearing seat body 9 is sleeved on the positioning rod 18, the bearing seat body 9 is clamped and fixed by the clamping plate 12 and the pressure plate at the same time, thereby improving the overall stability of the bearing seat body 9. Stability, then the drilling mechanism 23 is driven by the lifting mechanism 3 to drill a hole on one side of the bearing seat body 9. When it is necessary to drill a hole on the other side of the bearing seat body 9, it is only necessary to drive the drilling mechanism 23 to rise by the lifting mechanism 3, and then the direction of the drilling mechanism 23 can be adjusted by the rotating mechanism 4. The overall operation is simple and convenient, which improves the efficiency of drilling holes on the bearing seat body 9 and avoids multiple adjustments of the pressure plate 13 to disassemble and replace the position of the bearing seat body 9. This solves the problem that when the existing bearing seat processing drilling machine drills holes on both sides of the bearing group body, it is necessary to adjust the pressure plate multiple times through the threaded rod and then replace the position of the bearing seat body, thereby causing low drilling efficiency of the bearing seat.
