Description

Technical Field

[0001] This utility model relates to the field of automotive air filter housing processing technology, specifically an automotive air filter housing bolt assembly fixture. Background Technology

[0002] During the manufacturing process of automotive air filter housings, injection molding is first used to form the housing, followed by drilling threaded holes in the fastener and tightening bolts. Currently, the bolt tightening is still done manually, which is time-consuming and labor-intensive. While existing bolt-locking robots can perform the bolt-locking operation precisely, they rely on fast and accurate positioning fixtures. However, since different air filter housings have different dimensions, developing a set of fixtures for each product would be too costly for small-batch production lines. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a bolt assembly tooling for an automotive air filter housing, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model discloses a bolt assembly fixture for an automotive air filter housing. The technical solution includes a bolt-locking robot connected to a bolt supply mechanism, a base frame with a support member and a pressing mechanism, an inner support positioning mechanism and a directional rod mounted on the support member, the directional rod and the inner support positioning mechanism being arranged on the same side; the pressing mechanism and the inner support positioning mechanism are arranged opposite to each other; a robot base is also provided on the base frame, the robot base including a mounting platform, a linear displacement mechanism and a rotation mechanism mounted on the mounting platform, the rotation mechanism being connected to a turntable, and the bolt-locking robot mounted on the turntable; a control device and an operating table are also included, the control device being electrically connected to the bolt-locking robot, the linear displacement mechanism, the rotation mechanism, and the operating table. The inner support assembly supports the air filter housing from the inside, thereby performing initial positioning of the air filter housing; the pressing mechanism presses the air filter housing onto the support member for axial positioning; and the directional rod defines the orientation of the air filter housing for circumferential positioning. The three mechanisms enable rapid positioning of the air filter and offer excellent compatibility with air filter housings of different sizes.

[0005] In a preferred embodiment of this invention, the inner support positioning mechanism includes a fixed rod with a screw mounted on it. A nut engages with the screw, and a sleeve is axially connected to the nut. The sleeve is fitted onto the screw. Connecting rods are hinged to both the fixed rod and the sleeve, forming a scissor structure. The ends of the two connecting rods furthest from the screw are hinged to the same inner support rod, which is aligned with the screw. Tightening the nut adjusts the distance between the sleeve and the fixed rod, thereby adjusting the state of the scissor structure and, consequently, the distance between the inner support rod and the screw. The nut adjustment ensures that the current position is stably maintained after adjustment to a suitable location.

[0006] In a preferred embodiment of this invention, a guide section is connected to one end of the inner support rod near the pressing mechanism. This guide section is a guide rod bent towards the screw. The guide rod facilitates the fitting of the automotive air filter housing onto the inner support rod.

[0007] In a preferred embodiment of this invention, the pressing mechanism includes a chuck with jaws and a push rod mounted on the jaws. A linear sliding assembly is mounted on the base frame, and the chuck is mounted on the linear sliding assembly. The linear sliding assembly is connected to a pushing power source, which is electrically connected to the control device. By pushing the linear sliding assembly with the pushing power source, the chuck moves towards the inward support positioning mechanism, thus pressing the automotive air filter housing onto the support member.

[0008] As a preferred embodiment of this utility model, the linear sliding assembly includes a first slide rail, which has two sets and is installed in parallel on the base frame. A first slider is slidably connected to the first slide rail, and a bracket is mounted on the first slider. The bracket is connected to the chuck. The pushing power source is connected to the first slider.

[0009] As a preferred technical solution of this utility model, the pushing power source is one of the following: electric cylinder, electric push rod, lead screw linear displacement system, pneumatic cylinder, and hydraulic cylinder.

[0010] As a preferred embodiment of this utility model, the linear displacement mechanism mounted on the mounting platform is a lead screw system, including a lead screw slider. The mounting platform and the lead screw slider are connected, and the lead screw system is mounted on the base frame. The base frame is also equipped with a second slide rail, on which a second slider is slidably connected. The mounting platform and the second slider are connected. The lead screw system is electrically connected to the control device.

[0011] As a preferred embodiment of this utility model, the rotating mechanism mounted on the mounting platform includes a rotary motor, which is a servo motor, and its output end is connected to a reducer. The output end of the reducer is connected to a driving synchronous pulley. A driven synchronous pulley is connected to the upper shaft of the mounting platform. The driven synchronous pulley is connected to the turntable. A synchronous belt is fitted between the driving synchronous pulley and the driven synchronous pulley.

[0012] In a preferred embodiment of this invention, the support member has a sliding groove, and the directional rod has a third slider that is slidably connected within the sliding groove. The directional rod has a second threaded hole penetrating the third slider, and a locking bolt engages within the second threaded hole, with the locking bolt making slidable contact with the sliding groove. The directional rod can slide along the support rod, thus providing adjustment capability.

[0013] Compared with existing technologies, the advantages of this invention are as follows: This invention, by setting an internal support positioning mechanism, can support and position the interior of the automotive air filter housing; by setting a top-pressing mechanism, it can axially position the automotive air filter housing; and by setting a directional rod, it can circumferentially position the housing. These three positioning structures enable quick and accurate clamping of the automotive air filter housing.

[0028] The working principle of this utility model:

[0029] The staff set the processing parameters on the host computer according to the dimensions of the air filter housing 8.

[0030] During the initial processing, the air filter housing 8 with the first threaded hole 802 is fitted onto the inner support positioning mechanism 3, keeping the fastening seat 801 facing upwards. The nut 304 is turned with a wrench, and the nut 304 drives the sleeve 303 to move towards the support member 2 along the axis of the screw 302. The scissor structure of the connecting rod 305 causes the inner support rod 306 to be supported towards the inner wall of the air filter housing 8. After it is in contact with the inner wall of the air filter housing 8, the locking bolt of the directional rod 4 is loosened, and the directional rod 4 is slid downwards along the slide groove 201 until the directional rod 4 is in contact with the upper surface of the fastening seat 801. The locking bolt is then tightened to position the directional rod 4.

[0031] Adjust the opening degree of the jaws 502 on the chuck 501 so that the push rod 504 is aligned with the air filter housing 8. The operator presses down the push button 601 on the operating table 6. The PLC controller controls the air circuit control system to extend the cylinder 509. The cylinder 509 pushes the synchronizing element 507 to move the first slider 506 along the first slide rail 508, so that the push rod 504 presses the air filter housing 8 onto the support member 2.

[0032] The PLC controller controls the lead screw system 701 and rotary motor 705 of the robot base 7 according to the set program, controls the turntable 708 to move and rotate, adjusts the position and orientation of the bolt-locking robot, and drives the bolt-locking robot to perform bolt-locking operations in the first threaded hole 802. The bolt supply mechanism supplies bolts to the bolt-locking robot.

[0033] After the bolt tightening operation is completed, the PLC controller controls the cylinder 509 to reset, and the operator removes the air filter housing 8 along the axial direction of the screw 302.

[0034] When processing the air filter housing 8 in the same batch, the air filter housing 8 is directly put onto the inner support positioning mechanism 3. When putting it on, the directional rod 4 is connected to the fastening seat 801 of the air filter housing 8. The pressing button 601 is pressed down, the pressing mechanism 5 is activated to press the air filter housing 8 and perform the bolt locking operation. After the bolt locking operation is completed, the cylinder 509 is reset, and the operator removes the air filter housing 8 along the axial direction of the screw 302.
