Description

Technical Field

[0001] The present application relates to the technical field of fixing devices, and in particular to a fixing fixture for a bolt pad. Background Art

[0002] With the development of society and the advancement of science and technology, cars have become an indispensable means of transportation in people's daily lives. Leaf springs (referred to as leaf springs) are the most widely used elastic elements in automobile suspensions, which can ensure that the car has good load-bearing capacity, comfort and safety.

[0003] When installing the automobile engine housing, the bolt pad is a kind of spare part that is often needed. When the mounting hole on the bolt pad is threaded, the bolt pad is first placed on the processing base and then fixed, and then the threading operation is performed through the drill bit.

[0004] With regard to the above-mentioned related technologies, workers need to manually align holes during the threading operation on bolt pads. During the manual aligning of holes, the bolt pads will be displaced to a certain extent. During the aligning and drilling process, a lot of time is required to fix the bolt points. Utility Model Content

[0005] In order to improve the efficiency of threading holes in bolt pads, the present application provides a fixing fixture for bolt pads.

[0006] The present application provides a fixing fixture for a bolt pad, which adopts the following technical solution:

[0007] A fixing fixture for a bolt pad, comprising a fixing plate, a limiting assembly and a fixing assembly, wherein a limiting slide groove is provided at a central position of the fixing plate, and two fixing slide grooves are symmetrically provided on the fixing plate with the straight line where the limiting slide groove is located as a symmetry axis, the fixing slide groove is longer than the limiting slide groove, and the limiting assembly slides in the limiting slide groove; the limiting assembly is used to limit the bolt pad, and the fixing assembly is used to fix the bolt pad, and the fixing assembly comprises a horizontal driving member, a longitudinal driving member and an intercepting member, the horizontal driving member is provided at the end of the fixing slide groove, the longitudinal driving member is provided on the horizontal driving member at the ends of two fixing slide grooves on the same side, and the intercepting member is provided at an end of the longitudinal driving member away from the horizontal driving member.

[0008] By adopting the above technical scheme, the bolt plate is first limited by the limiting component so that the bolt plate will not deviate significantly. Secondly, the longitudinal driving member and the intercepting member are driven by the horizontal driving member to approach the bolt plate from both sides until the intercepting member is in close contact with the bolt plate, and the bolt plate is fixed from both sides by the intercepting member. Finally, the longitudinal driving member drives the intercepting member to drive the bolt plate to move downward from the top of the limiting component until the bolt plate is firmly limited and fixed, and the driving is stopped. Through the above operations, the bolt plate is firmly fixed on the limiting member. At this time, threading the holes of the bolt plate can greatly improve the work efficiency.

[0009] Optionally, the limit assembly includes a limit column, a slider, a bidirectional screw and a drive motor. The bidirectional screw is arranged in the limit slide groove and is rotatably connected to the end of the limit slide groove. The drive motor is arranged at one end of the bidirectional screw. Two sliders are provided, and the two sliders are respectively threadedly connected to opposite threads of the bidirectional screw. The limit column is arranged at the top of the slider.

[0010] By adopting the above technical solution, the motor is first driven to drive the bidirectional screw to rotate. The rotation of the bidirectional screw will drive the slider to move toward or away from each other on the bidirectional screw, thereby driving the limit column to move toward or away from each other. When the center distance between the two limit columns moves to a suitable position, the bolt plate is installed on the limit column, thereby limiting the position of the bolt plate and further enhancing the fixing effect of the bolt plate.

[0011] Optionally, a flexible material is provided on the limiting column.

[0012] By adopting the above technical solution, the flexible material is tightly wrapped around the limiting column, so that there will be no rigid collision and friction between the bolt pad and the limiting column when they are in contact, thereby avoiding rigid damage to the bolt pad caused by limiting.

[0013] Optionally, the limiting column is detachably connected to the sliding block.

[0014] By adopting the above technical solution, the detachable design of the limiting column greatly increases the adaptability of the fixing fixture to different types of bolt pads. When facing different types of bolt pads, they can be limited by replacing different types of limiting columns.

[0015] Optionally, the fixed component includes a horizontal driving member, a longitudinal driving member and an intercepting member, the horizontal driving member is a cylinder, the cylinder is arranged at the end of the fixed slide groove, the longitudinal driving member is arranged at the pushing end of the cylinder, and the intercepting member is arranged at the end of the longitudinal driving member away from the cylinder.

[0016] By adopting the above technical solution, the cylinder can drive the pushing end to extend and retract, driving the longitudinal driving part and the intercepting part to fix and move the bolt pad. At the same time, the characteristic of the cylinder is that during the pushing process, once the pushing end encounters resistance, the gas inside it will have a buffering effect on the pushing end, so that when the intercepting part and the bolt pad are in contact, it can better protect the bolt pad and the intercepting part from being damaged due to rigid contact, thereby greatly improving the service life.

[0017] Optionally, the longitudinal driving member is a push rod, the fixed end of the push rod is fixedly connected to the push end of the cylinder, and the push end of the push rod is fixedly connected to the intercepting member.

[0018] By adopting the above technical solution, the intercepting member first contacts the bolt pad at a suitable angle under the adjustment of the push rod, and after being closely contacted with the bolt pad under the drive of the cylinder, the position of the bolt pad on the limit assembly is moved by the extension and retraction of the push rod, which can more conveniently achieve the purpose of adjusting the position of the bolt pad and reduce the cost of manual labor to a certain extent.

[0019] Optionally, the intercepting member includes an arc plate, a blocking plate and a micro motor, the arc plate is arranged along the vertical direction of the fixed slide groove, the arc plate is fixedly connected to the pushing end of the pushing rod, the blocking plate is rotatably connected to the top end of the arc plate, and the micro motor is arranged at the end of the blocking plate to drive the blocking plate to rotate.

[0020] By adopting the above technical solution, the arc plate can perfectly fit with the side of the bolt pad, which is more conducive to fixing the bolt pad. The micro motor can drive the blocking plate to rotate to the appropriate position, and play a fixing and pressing role on the bolt pad from the top of the bolt pad. Under the dual action of the arc plate and the bolt pad, the bolt pad can be firmly fixed on the limit assembly, and the stability of the bolt pad is greatly increased.

[0021] Optionally, a flexible material is provided on the side of the arc-shaped plate in contact with the bolt pad.

[0022] By adopting the above technical scheme, under the protection of flexible materials, the rigid contact between the bolt pad and the arc plate can be effectively reduced, and the contact area between the arc plate and the bolt pad can be increased, thereby increasing the friction on the bolt pad, so that the bolt pad can be better fixed and protected, which not only reduces movement during the threading and drilling process, but also avoids the rigid friction between the bolt pad and the arc plate caused by the vibration generated during drilling and threading, thereby extending the service life of the bolt pad and the arc plate.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] By setting the limit assembly and the fixing assembly, the bolt pad can be initially fixed on the fixing plate. When the bolt pad is manually threaded and drilled, the worker manually fixes the bolt pad. During the threading and drilling process, the position of the bolt pad is easily offset due to the vibration of the drill bit, resulting in a deviation between the drilling position and the original position, which makes the bolt pad unable to be put into subsequent use. After the bolt pad is limited by the limit assembly and the fixing assembly, the probability of the bolt pad being offset can be effectively reduced during threading and drilling, which greatly reduces the defective rate of the bolt pad.

[0025] By setting the limit column to move toward or away from each other on the bidirectional screw, it can be easily adapted to bolt pads of different models. At the same time, the setting of the cylinder and the push rod in the fixing assembly can also adapt to bolt pads of different sizes. The detachable limit column is used for bolt pads of different apertures. For bolt pads of different models and sizes, different limit columns can be replaced to adapt to the aperture on the bolt pad, thereby effectively increasing the tolerance of the fixing fixture for bolt pads of different models;

[0026] By setting flexible materials, the hard contact between the arc plate and the bolt pad, as well as the hard contact between the limit column and the bolt pad can be reduced. Since the contact between metal materials may cause irreversible hard damage to the metal material, there will be a certain degree of error in subsequent work and use. For the fixing fixture, the subsequent fixing work may cause the displacement of the bolt pad. For the bolt pad, the subsequent use scenarios will affect its service life. Therefore, the use of flexible materials for protection is two-way, which not only protects the fixing fixture, but also protects the bolt pad, so that the contact between the fixing fixture and the bolt pad becomes soft contact, and at the same time increases the friction on the bolt pad, making the fixing effect better.

A limiting slide groove 11 is opened at the center position of the fixing plate 1. Two fixing slide grooves 12 are symmetrically opened on the fixing plate 1 with the straight line where the limiting slide groove 11 is located as the symmetry axis. The length of the fixing slide groove 12 is longer than the limiting slide groove 11, and the limiting assembly 2 slides in the limiting slide groove 11; the limiting assembly 2 is used to limit the bolt pad, and the fixing assembly 3 is used to fix the bolt pad. The fixing assembly 3 comprises a horizontal driving member 31, a longitudinal driving member 32 and an intercepting member 33. The present embodiment discloses four horizontal driving members 31 and four longitudinal driving members 32. Each of the two ends of the fixing slide groove 12 is welded with a horizontal driving member 31, and each of the ends of the horizontal driving member 31 away from the end of the fixing slide groove 12 is welded with a longitudinal driving member 32. There are two intercepting members 33, and the two intercepting members 33 are respectively welded to the ends of the two longitudinal driving members 32 on the same side away from the horizontal driving member 31.

[0034] Reference Figure 1 and Figure 2 The fixed assembly 3 includes a horizontal driving member 31, a longitudinal driving member 32 and an intercepting member 33. The horizontal driving member 31 is a cylinder 311, which is welded to the end of the fixed slide 12. The longitudinal driving member 32 is a push rod 321, one end of which is welded to the push end of the cylinder 311. The push end of the push rod 321 is vertically upward. The intercepting member 33 includes an arc plate 331, a blocking plate 332 and a micro motor 333. The convex side of the arc plate 331 is connected to the top of the push rod 321. The push end is welded, and a flexible material is pasted on the concave side of the arc plate 331. The flexible material disclosed in this embodiment is a rubber layer. The concave parts of the two arc plates 331 are arranged opposite to each other, and the blocking plate 332 is hinged on the vertically upward side of the arc plate 331. The micro motor 333 is installed on the arc plate 331 by bolts, and the driving end of the micro motor 333 is welded to the hinge of the blocking plate 332 and the arc plate 331. The blocking plate 332 can be driven to rotate along the hinge by the micro motor 333.

[0035] Reference Figure 1 and Figure 3 The limit assembly 2 includes a limit column 21, a slider 22, a bidirectional screw 23 and a drive motor 24. The two ends of the bidirectional screw 23 are rotatably connected to the two ends of the limit slide 11 respectively. The drive motor 24 is installed on one side of the fixed plate 1 by bolts. The driving end of the drive motor 24 is welded to one end of the bidirectional screw 23. The present embodiment discloses two sliders 22. The two sliders 22 are respectively threadedly connected to the opposite threads of the bidirectional screw 23, and are located in the limit slide 11 and slidably connected to the limit slide 11. The limit column 21 is installed on the top of the slider 22 by threaded connection, and a rubber layer is wrapped on the two limit columns 21.

[0036] The implementation principle of a fixing fixture for a bolt pad in an embodiment of the present application is as follows: when drilling holes in the bolt pad, the bidirectional screw 23 is first driven to rotate by a driving motor 24, and the bidirectional screw 23 drives the slider 22 to move toward or away from the limiting slide groove 11 through threads and then stops moving to a suitable position, and a worker puts the bolt pad on the limiting column 21 on the slider 22. The limiting column 21 can be replaced according to the bolt pad model, and the disassembly and installation of the limiting column 21 are both achieved through threads. When the bolt pad is put on the limit column 21, the cylinder 311 starts to push forward, and the pushing rod 321 adjusts the position of the arc plate 331 in time. When the recessed side of the arc plate 331 and the bolt pad are engaged with each other, the cylinder 311 slowly continues to push forward until the bolt pad is firmly fixed from both sides. At this time, the micro motor 333 drives the blocking plate 332 to start rotating along the top side of the arc plate 331 until the blocking plate 332 tightly fixes the bolt pad from top to bottom. At this time, the pushing rod 321 is controlled to move slowly downward until the bolt pad is The plate is firmly fixed on the fixed plate 1 and the drilling and threading process can be carried out. After the drilling and threading are completed, the push rod 321 controls the bolt pad to move upward until the bolt pad is completely detached from the limiting column 21. At this time, the micro motor 333 is controlled to drive the blocking plate 332 to rotate toward the raised side of the arc plate 331 until the blocking plate 332 is in close contact with the raised side of the arc plate 331, and then the cylinder 311 is controlled to be recovered to completely release the bolt pad. During the whole process, the rubber layer protects the arc plate 331, the limiting column 21 and the bolt pad from rigid contact.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
