Description

A fixed fixture for drilling holes in automotive longitudinal beams Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically a fixed tooling for drilling holes in automotive longitudinal beams. Background Technology

[0002] Drilling holes in automotive longitudinal beams serves several purposes. The vehicle's suspension system needs to be fixed to the longitudinal beams using bolts and other connectors. Drilling holes in the longitudinal beams provides mounting positions, allowing the suspension system to be installed accurately, ensuring vehicle stability and comfort, and maintaining the correct relative position between the wheels and the vehicle body. This enables effective cushioning and shock absorption during driving. Additionally, key components of the braking system, such as brake line mounting brackets and brake calipers, need to be installed on the longitudinal beams. Drilling holes in the longitudinal beams allows these components to be securely connected, ensuring the braking system functions properly, providing good braking performance, and guaranteeing driving safety. For vehicles with driveshafts, the holes in the longitudinal beams are used to install driveshaft support components or related connecting parts, ensuring the driveshaft can accurately transmit power, enabling the vehicle's power transmission system to operate stably, and effectively transmitting engine power to the drive wheels for normal vehicle operation.

[0003] The existing technical solution has the following drawbacks: When drilling the longitudinal beam of an automobile, the longitudinal beam must be firmly fixed first to complete the drilling operation on one side. However, when drilling the other side of the longitudinal beam, the current fixing state must be released first and then the fixing operation must be performed again. This not only increases the number of operation steps, but also makes the entire longitudinal beam processing process quite cumbersome and complicated, which reduces the processing efficiency to a certain extent. Summary of the Invention

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a fixing fixture for drilling automotive longitudinal beams. This fixture facilitates drilling and solves the problem that when drilling automotive longitudinal beams, the longitudinal beam must first be firmly fixed to complete the drilling operation on one side. However, when drilling the other side of the longitudinal beam, the current fixing state must be released and then the fixing operation must be repeated. This not only increases the number of operation steps but also makes the entire longitudinal beam processing flow quite cumbersome and complicated, reducing processing efficiency to a certain extent.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixed fixture for drilling holes in automotive longitudinal beams, comprising a base plate, a flat plate fixedly connected to the top of the base plate, two sliding grooves provided on the top of the flat plate, a fixing mechanism provided on the top of the base plate, and an auxiliary support assembly provided on the top of the flat plate.

[0006] In a preferred embodiment of this utility model, the fixing mechanism includes two mounting seats. The bottom of each mounting seat is fixedly connected to the top of the base plate. A forward and reverse lead screw is rotatably connected to the inner side of each mounting seat. A knob is fixedly connected to the right side of each forward and reverse lead screw. A drive rod is threadedly connected to the surface of each forward and reverse lead screw. The outer side of the drive rod is slidably connected to the inside of a sliding groove. A connecting seat is fixedly connected to the top of the drive rod. A round rod is rotatably connected to the inner side of the connecting seat. A clamping sleeve is fixedly connected to the inner side of the round rod. One end of one of the round rods is fixedly connected to a rotating wheel.

[0007] In a preferred embodiment of this invention, the auxiliary support assembly includes a reinforcing plate, the bottom of which is fixedly connected to the top of the flat plate. A movable rod is slidably connected inside the reinforcing plate, a support plate is fixedly connected to the top of the movable rod, and a pull rod is fixedly connected to the outside of the support plate.

[0008] As a preferred embodiment of this utility model, a connecting groove is provided on the inner side of the tray, and the connecting groove is located at the top of the reinforcing plate.

[0009] In a preferred embodiment of this invention, the top of the tray is L-shaped and is located on top of the flat plate.

[0010] In a preferred embodiment of this invention, the inside of the clamping sleeve is square-shaped, and the clamping sleeve is located on the top of the plate.

[0011] As a preferred embodiment of this invention, a rubber pad is fixedly connected inside the clamping sleeve, and the rubber pad is located at the top of the sliding groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through the use of a fixing mechanism, enables the rapid fixing of automotive longitudinal beams. The auxiliary support components provide support to the bottom of the automotive longitudinal beams. This solves the problem that when drilling automotive longitudinal beams, it is necessary to first firmly fix the longitudinal beams to complete drilling on one side. However, when drilling on the other side of the longitudinal beam, the current fixing state must be released and then the fixing operation repeated. This not only increases the number of steps but also makes the entire longitudinal beam processing flow quite cumbersome and complex, reducing processing efficiency to some extent. This invention offers the advantage of facilitating drilling.

[0014] 2. This utility model sets up a fixing mechanism. By rotating the knob, the knob drives the forward and reverse lead screws to rotate synchronously. Due to the thread transmission of the lead screw, the drive rod connected to the lead screw begins to move relative to it. The movement of the drive rod drives the connecting seat at its top, the round rod inside the connecting seat, and the clamping sleeve inside the round rod to move relative to each other until the clamping sleeve accurately clamps the two ends of the automobile longitudinal beam, so that the longitudinal beam is firmly fixed, thus improving the fixing efficiency of the automobile longitudinal beam.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] As shown in Figures 1 to 4, the present invention provides a fixing fixture for drilling automotive longitudinal beams, including a base plate 1, a flat plate 2 fixedly connected to the top of the base plate 1, two sliding grooves 3 on the top of the flat plate 2, a fixing mechanism 4 on the top of the base plate 1, and an auxiliary support assembly 5 on the top of the flat plate 2.

[0022] Referring to Figure 4, the fixing mechanism 4 includes a mounting base 41. There are two mounting bases 41. The bottom of the mounting base 41 is fixedly connected to the top of the base plate 1. A forward and reverse screw 42 is rotatably connected to the inner side of the mounting base 41. A knob 43 is fixedly connected to the right side of the forward and reverse screw 42. A drive rod 44 is threadedly connected to the surface of the forward and reverse screw 42. The outer side of the drive rod 44 is slidably connected to the inside of the sliding groove 3. A connecting seat 45 is fixedly connected to the top of the drive rod 44. A round rod 46 is rotatably connected to the inner side of the connecting seat 45. A clamping sleeve 47 is fixedly connected to the inner side of the round rod 46. A rotating wheel 48 is fixedly connected to one end of one of the round rods 46.

[0023] As a technical optimization of this utility model, by setting a fixing mechanism 4, by rotating the knob 43, the knob 43 drives the forward and reverse lead screws 42 to rotate synchronously. Due to the thread transmission of the lead screw, the drive rod 44, which is threadedly connected to the lead screw, begins to move relative to it. The movement of the drive rod 44 drives the connecting seat 45 at its top, the round rod 46 inside the connecting seat 45, and the clamping sleeve 47 inside the round rod 46 to move relative to each other until the clamping sleeve 47 accurately clamps the two ends of the automobile longitudinal beam, so that the longitudinal beam is firmly fixed, thereby improving the fixing efficiency of the automobile longitudinal beam.

[0024] Referring to Figure 2, the auxiliary support component 5 includes a reinforcing plate 51, the bottom of which is fixedly connected to the top of the plate 2. A movable rod 52 is slidably connected inside the reinforcing plate 51, a support plate 53 is fixedly connected to the top of the movable rod 52, and a pull rod 54 is fixedly connected to the outside of the support plate 53.

[0025] As a technical optimization of this utility model, by setting an auxiliary support component 5, by pushing the pull rod 54, the pull rod 54 drives the pallet 53 and the moving rod 52 to move relative to each other until the two pallets 53 come into contact with each other. At this time, the two pallets 53 are tightly locked together by the unique connecting groove 6 on the inner side of the pallet 53. After the locking is completed, the automobile longitudinal beam is placed stably on the pallet 53, so that the longitudinal beam is in the center of the processing to ensure the accuracy of subsequent processing.

[0026] Referring to Figure 3, a connecting groove 6 is provided on the inner side of the support plate 53, and the connecting groove 6 is located on the top of the reinforcing plate 51.

[0027] As a technical optimization of this utility model, by setting the connecting groove 6, the two trays 53 can be quickly snapped together, thereby performing preliminary positioning of the automobile longitudinal beam and significantly improving the positioning efficiency of the automobile longitudinal beam.

[0028] Referring to Figure 3, the top of the tray 53 is L-shaped and is located on top of the plate 2.

[0029] As a technical optimization of this utility model, the L-shaped top of the support plate 53 allows it to better fit the bottom of the automotive longitudinal beam, thereby enabling more precise positioning of the automotive longitudinal beam.

[0030] Referring to Figure 4, the inside of the clamping sleeve 47 is square-shaped, and the clamping sleeve 47 is located on the top of the plate 2.

[0031] As a technical optimization of this utility model, the internal shape of the clamping sleeve 47 is square, which allows it to be adapted to both ends of the automobile longitudinal beam, effectively improving the fixing efficiency of the automobile longitudinal beam.

[0032] Referring to Figure 3, a rubber pad 7 is fixedly connected inside the clamping sleeve 47, and the rubber pad 7 is located at the top of the sliding groove 3.

[0033] As a technical optimization of this utility model, by setting the rubber pad 7, when the clamping sleeve 47 fixes the longitudinal beam of the car, it can avoid scratching the surface of the longitudinal beam of the car from the inside of the clamping sleeve 47, thus playing a good protective role.

[0034] The working principle and usage process of this utility model are as follows: When preparing to drill holes in the automotive longitudinal beam, firstly, push the pull rod 54. The pull rod 54 drives the support plate 53 and the moving rod 52 to move relative to each other until the two support plates 53 come into contact. At this time, the unique connecting groove 6 on the inner side of the support plate 53 is used to tightly engage the two support plates 53 together. After the engagement is completed, place the automotive longitudinal beam stably on the support plate 53 so that the longitudinal beam is in the center position for processing to ensure the accuracy of subsequent processing. Next, rotate the knob 43. The knob 43 drives the forward and reverse lead screw 42 to rotate synchronously. Due to the thread transmission of the lead screw, the drive rod 44, which is threadedly connected to the lead screw, begins to move relative to each other. The movement of the drive rod 44 drives the connecting seat 45 at its top and the circular groove on the inner side of the connecting seat 45. The rod 46 and the clamping sleeve 47 inside the round rod 46 move relative to each other until the clamping sleeve 47 accurately clamps both ends of the automobile longitudinal beam, thus firmly fixing the longitudinal beam. At this point, the drilling equipment can be started to drill holes in the automobile longitudinal beam. After the automobile longitudinal beam is drilled, the pull rod 54 is pulled again, causing the pull rod 54 to drive the support plate 53 and the moving rod 52 to move in opposite directions, thereby disengaging the support plate 53 from the automobile longitudinal beam. Then, the rotating wheel 48 is rotated, and the rotating wheel 48 drives the clamping sleeve 47 to rotate through the round rod 46, thereby achieving a 180-degree flip of the automobile longitudinal beam. After the automobile longitudinal beam is flipped into place, the pull rod 54 is operated again to rotate the support plate 53 and re-clamp it, providing stable support for the flipped automobile longitudinal beam for subsequent processing operations.

[0035] In summary, the fixing fixture for drilling automotive longitudinal beams, through the coordinated use of base plate 1, flat plate 2, sliding groove 3, fixing mechanism 4, and auxiliary support assembly 5, solves the problem that when drilling automotive longitudinal beams, it is necessary to first firmly fix the longitudinal beam to complete the drilling operation on one side, but when drilling on the other side of the longitudinal beam, the current fixing state must be released and then the fixing operation must be performed again. This not only increases the number of operation steps but also makes the entire longitudinal beam processing flow quite cumbersome and complicated, reducing processing efficiency to a certain extent.
