[0002] An automobile seat is a seat for passengers when riding. The layout of seats in the whole carriage should be reasonable. In particular, the driver's seat must be in the best position; the shape design of the seat must conform to the physiological functions of the human body, and strive for beauty on the premise of ensuring comfort; the seat must be safe and reliable, with sufficient strength, stiffness and durability, and the structure should be compact and the mass should be reduced as much as possible; various adjustment mechanisms provided to meet the comfort of drivers and passengers should have reliable locking devices to ensure safety.

[0003] With the improvement of people's living standards, automobiles have become the first choice for many consumers. Due to the increasing number of traffic accidents caused by automobiles, consumers attach great importance to the safety performance of automobiles. Among them, the effective fixation of seats plays a crucial role in the safety of passengers. The fixation of automobile seats also needs to consider the issues of easy installation and maintenance. Generally speaking, the fixation of automobile seats is of great significance for ensuring passenger safety, improving riding comfort and enhancing driving performance. Therefore, both automobile manufacturers and users should pay attention to the quality and reliability of seat fixation when selecting and using automobile seats.

[0004] The bracket body on the inner side of the front row seat is integrally in a U-shaped structure, and one of the corners of the bracket body is inclined; during the manufacturing and installation process, it is necessary to ensure both simple manufacturing processes and the fixing strength of the bracket after installation. Especially when drilling holes in the bracket body, due to the easy confusion of the structure of the bracket body, it may lead to mistakes in the processing direction when placed on the workbench, and at the same time, multiple sides of the bracket body need to be drilled. After flipping, it is easy to deviate. The above two situations will both increase the rejection rate. Summary of the Utility Model

[0005] In order to solve the problems of easy placement errors and increased rejection rate caused by flipping deviation during the drilling process of the bracket body, the utility model provides a processing tool for positioning the inner bracket at the rear of the front row seat for installation.

[0006] The utility model is realized by the following technical solutions:

[0008] The positioning unit includes a limit plate for blocking the movement of the bracket body in the X-axis direction of the bridge plate, a push assembly for pressing the bracket body against the limit plate, and an anti-error rod that cooperates with the inclined surface on the bracket body; the limit plate, push assembly and anti-error rod are all installed on the bridge plate.

[0009] The bracket body is placed on the workpiece processing position and fixed by a positioning unit, in which the anti-error rod can cooperate with the inclined surface of the bracket body to avoid assembly errors of the bracket body on the tooling. After the bridge plate is flipped to a certain angle with the help of a flipping device, the drilling positions on other surfaces of the bracket body are guaranteed to be accurate, which helps to improve operational efficiency while reducing scrap rate.

[0010] A further improvement of the utility model is that the above-mentioned push assembly includes a push cylinder, and the ejection end of the push cylinder is provided with a push plate for pushing the bracket body. The push cylinder ejects the push plate outward, and the push plate pushes the bracket body and the limit plate to form a clamping fixation in the X direction.

[0011] A further improvement of the utility model is that the bridge plate is also provided with a cylinder pad for supporting the horizontal push cylinder. The cylinder pad can compensate for the center of gravity height of the horizontal push cylinder.

[0012] A further improvement of the utility model is that the above-mentioned error-proofing rod is in an L-shaped structure as a whole. The L-shaped error-proofing rod has a simple structure and cooperates with the inclined surface of the bracket body to prevent installation errors.

[0013] A further improvement of the utility model is that the positioning unit further comprises a pressing assembly for pressing the top of the bracket body.

DETAILED DESCRIPTION

[0024] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0025] As attached Figure 1-3 As shown, a processing tool for positioning the inner bracket after the front seat is installed, comprising a bridge plate 10, and clamping blocks 11 are provided at both ends of the bridge plate 10. The clamping blocks 11 increase the contact area between the flipping device and the bridge plate 10. The bridge plate 10 is provided with a plurality of workpiece processing positions 12, and the periphery of the workpiece processing positions 12 is provided with positioning units 20.

[0026] The positioning unit 20 includes a limit plate for blocking the bracket body 30 from moving in the X-axis direction of the bridge plate 10, a push assembly for pressing the bracket body 30 against the limit plate, and an anti-error rod 22 that cooperates with the inclined surface on the bracket body 30; the limit plate, the push assembly and the anti-error rod 22 are all installed on the bridge plate 10.

[0027] The workpiece processing position 12 is provided with a positioning seat 23 that matches the groove of the bracket body 30. The positioning seat 23 forms a match with the bottom surface of the bracket body 30, which helps to facilitate the installation and guidance of the bracket body 30 on the bridge plate 10.

[0028] The limiting plate and the parallel push assembly are arranged on two sides of the positioning seat 23 and are arranged opposite to each other.

[0029] The push assembly includes a push cylinder 24, and the ejection end of the push cylinder 24 is provided with a push plate 241 for pushing the bracket body 30. The push cylinder 24 ejects the push plate 241 outward, and the push plate 241 pushes the bracket body 30 and the limit plate to form a clamping fixation in the X direction.

[0030] The bridge plate 10 is also provided with a cylinder pad 25 for supporting the push cylinder 24. The cylinder pad 25 can compensate for the center of gravity height of the push cylinder 24, thereby forming a height to avoid the positioning seat 23, so that the effective contact area between the push plate 241 and the bracket body 30 is increased.

[0031] The anti-error rod 22 is in an L-shaped structure as a whole. The L-shaped anti-error rod 22 has a simple structure and cooperates with the inclined surface of the bracket body 30 to prevent installation errors.

[0032] The positioning unit 20 further includes a pressing assembly for pressing the top of the bracket body 30. The pressing assembly can press the bracket body 30 in the Y direction, and can also increase the stability of the bracket body 30 after the bracket body 30 rotates with the bridge plate 10. The pressing assembly includes a pressing cylinder 21 disposed on the bridge plate 10, and a pressing plate 211 is disposed at the ejection end of the pressing cylinder 21.

[0033] Since the lower pressing plate 211 is in contact with the top surface of the bracket body 30 in the initial state, and the top surface of the bracket body 30 needs to be drilled, a space is provided on the lower pressing plate 211 to avoid the drilling position.

[0034] The lower pressing plate 211 and the push plate 241 are provided with buffer blocks on the surfaces close to the workpiece processing position 12 , which helps to reduce the wear of the bracket body 30 and improve the stability of the bracket body 30 on the workpiece processing position 12 by using friction force.

[0035] The pressing cylinder 21 is arranged on a side of the limiting plate away from the positioning seat 23 .

[0036] The lower pressing plate 211 is rotatably arranged at the ejecting end of the lower pressing cylinder 21, avoiding interference when the bracket body 30 is taken out from the workpiece processing position 12.

[0037] In summary, when the device is in use: in the initial state, the horizontal pushing cylinder 24 is in a contracted state, the lower pressing cylinder 21 is in an extended state, and at the same time, the lower pressing plate 211 can rotate on the upper plane of the ejecting end of the lower cylinder. At this time, rotate the lower pressing plate 211 away from the area corresponding to the workpiece processing position 12 to avoid interference with the installation of the bracket body 30 onto the workpiece processing position 12; as shown in the attached Figure 2 and 3 it can be seen that the inclined surface of the bracket body 30 is at one of the corners. At the same time, considering that the overall structure of the bracket body 30 is in a "冂" shape, when the bracket body 30 is installed onto the positioning seat 23, the bracket body 30 needs to be installed from the side close to the horizontal pushing cylinder 24, and the bracket body 30 slides from the side of the horizontal pushing cylinder 24 towards the side of the lower pressing cylinder 21, so that the anti-misalignment rod 22 cooperates with the inclined surface on the bracket body 30 to complete the guiding installation; rotate the lower pressing plate 211 back above the bracket body 30, and start the horizontal pushing cylinder 24 and the lower pressing cylinder 21 successively, thereby ensuring the clamping and fixing of the bracket body 30 after it is installed in place.

[0038] When drilling and processing the top surface of the bracket body 30, the bridge plate 10 does not rotate. When drilling and processing the two side surfaces of the bracket body 30, use the flipping device to flip the bridge plate 10 by 90° to ensure continuous processing of the bracket body 30.

[0039] For a processing tooling for positioning the inner bracket for the rear installation of the front row seat of the present utility model, the bracket body is placed on the workpiece processing position and fixed by the positioning unit. Among them, the anti-misalignment rod can cooperate with the inclined surface of the bracket body to avoid assembly errors of the bracket body on the tooling. After flipping the bridge plate by a certain angle with the help of the flipping device, it ensures the accuracy of the drilling positions on other surfaces of the bracket body, which helps to improve the operation efficiency and reduce the rejection rate at the same time.
