Description

Technical Field

[0001] This utility model relates to the field of automotive painting production lines, and more specifically, to a skid fulcrum auxiliary installation fixture. Background Technology

[0002] A skid is a key support device used to transport objects such as car bodies. A skid typically consists of two parallel long beams and a short beam connecting the two long beams. Each short beam has two fulcrums that can support the car body and lock it onto the skid.

[0003] However, these fulcrums are prone to paint buildup, aging, and deformation during frequent electrophoresis and baking processes, so they must be replaced after a period of use. Furthermore, the long-term baking of the skid can cause deformation, resulting in the measured position during installation not being able to fully match the drawing. Therefore, the mounting holes on the skid are designed as elongated holes to facilitate accuracy calibration and adjustment when replacing the fulcrums in the future.

[0004] Existing technologies require extensive manual data measurement and multiple position checks when reinstalling the fulcrum to ensure that the skid can accurately fall into the fulcrum when receiving the vehicle. The entire operation is complex, time-consuming, and labor-intensive. Existing technologies lack a tooling for fulcrum-assisted installation. Utility Model Content

[0005] The purpose of this invention is to overcome the problem of time-consuming and labor-intensive replacement process of existing fulcrums, and to provide an auxiliary installation tool for skid fulcrums, which provides assistance for the installation of skid fulcrums and makes the fulcrum replacement process simpler.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A skid fulcrum auxiliary installation fixture is provided, including a bracket, a positioning plate located on top of the bracket, and a connector for connecting the bracket and the positioning plate. The positioning plate is parallel to the horizontal plane and has a plurality of fulcrum positioning holes for installing fulcrums. The bracket is used for detachable connection with the skid. When the bracket and the skid are locked, the fulcrum positioning holes are located above the fulcrum installation part of the skid.

[0008] This utility model discloses an auxiliary installation fixture for a skid fulcrum. When replacing the skid fulcrum, the new fulcrum is first inserted into the fulcrum positioning hole from below the positioning plate. By rotating the fulcrum handle, the locking head of the fulcrum rotates horizontally by 90°, causing the locking head to lock onto the positioning plate, thereby locking the fulcrum onto the positioning plate. Then, the frame is placed on the skid, and the bracket and skid are locked. The bracket uses the skid itself for positioning, ensuring that the positioning plate is horizontal and that the position of the fulcrum positioning hole is above the skid fulcrum installation part. Since the positioning plate is pre-designed according to the vehicle body dimensions, the positioning plate at this time is equivalent to the vehicle body. The position of the fulcrum positioning hole on the positioning plate is consistent with the position of the locking hole on the vehicle body, thus ensuring... To ensure accurate vehicle connection, the fulcrum is positioned precisely. After positioning, the operator locks the fulcrum onto the elongated hole in the fulcrum mounting section. During this process, the fulcrum positioning hole provides a limit, preventing vibrations from the pneumatic wrench used during bolt fixing from causing changes in the fulcrum's installation position, resulting in better positioning accuracy. After the bolts are installed, the fulcrum handle is turned to unlock the fulcrum. Finally, the auxiliary installation tool is removed, completing the positioning and installation of the new fulcrum. This auxiliary installation tool provides positioning assistance, simplifying the fulcrum replacement process compared to existing technologies that require manual measurement, saving time and effort. Furthermore, the fulcrum positioning hole provides a limit, reducing offset during installation and improving accuracy.

[0009] Furthermore, the bracket includes two parallel support rods, two limiting rods parallel to the bottom of the support rods, and a locking rod connected to the support rods. The support rods are placed above the long beams of the sled. The two limiting rods abut against the inner sides of the two long beams of the sled, and the locking rod is used to connect to the short beam of the sled. Since the position of the short beam and the length of the locking rod are fixed, the bracket can be positioned and its movement in the direction parallel to the long beams of the sled can be restricted. The two limiting rods abut against the inner sides of the two long beams, restricting the movement of the bracket in the direction perpendicular to the long beams of the sled. Through these two mutually perpendicular restrictions, the bracket can be positioned and fixed on the sled, achieving rapid positioning and improved convenience.

[0010] Furthermore, the locking rod has a latching part at the end away from the support rod. The latching part has a U-shaped groove with an opening facing downwards, which is used to engage the skid short beam. The latching part with the U-shaped groove facilitates connection between the latching part and the short beam, resulting in a good fixing effect.

[0011] Furthermore, a fastener is provided on the inner side of the limiting rod, which is used to lock the limiting rod and the long slide beam. The fastener can improve the stability of the bracket, and when using a pneumatic wrench to install the fulcrum, it can better reduce vibration and improve the accuracy of the fulcrum installation.

[0012] Furthermore, the fastener is a bolt, and the limiting rod has a threaded hole. The fastener is threadedly connected to the threaded hole, and one end of the fastener is used to abut against the long beam of the skid. Using bolts as fasteners allows for quick and convenient operation; tightening secures the device, and loosening unlocks it.

[0013] Furthermore, the connector includes at least two connecting rods, which are perpendicular to the horizontal plane. One end of each connecting rod is connected to the bracket, and the other end is detachably connected to the positioning plate. The detachable connection between the positioning plate and the connecting rods allows the bracket to be fixed to the skid first, followed by the installation of the positioning plate on the skid, reducing the force required during transport. Additionally, the tooling is divided into two parts for easier storage and improved convenience.

[0014] Furthermore, the positioning plate has mounting holes that are the same number and position as the connecting rods. The outer wall of each connecting rod has a limiting portion, the outer diameter of which is larger than the diameter of the mounting hole. The mounting holes of the positioning plate can be aligned with the top of the connecting rod, and the connecting rod can be installed into the mounting hole. The limiting portion restricts the height of the positioning plate, making installation more convenient.

[0015] Furthermore, there are four fulcrum positioning holes, distributed at the same end of the connector, with each pair of fulcrum positioning holes forming a group, distributed on both sides of the connector. When the bracket is installed on the skid, the fulcrum positioning holes of each group are located above the corresponding skid fulcrum mounting part. After installing two fulcrums, new fulcrums can be installed and the positioning plate can be flipped so that the two new fulcrums are aligned with the two fulcrum mounting parts on the other side of the connector. The advantage of this design is that it reduces the area and weight of the positioning plate, making it easier to transport and operate.

[0016] Furthermore, several reinforcing rods are arranged parallel to each other on the top of the bracket. These reinforcing rods are perpendicular to the horizontal plane, and their tops abut against the bottom surface of the positioning plate. The reinforcing rods provide more support for the positioning plate, improving its stability.

[0017] Furthermore, there are four fulcrum positioning holes, arranged in pairs, with two sets of holes distributed at both ends of the connector. Each set of holes is located on both sides of the connector. When the bracket is installed on the skid, the four fulcrum positioning holes are positioned above the four skid fulcrum mounting points. After the bracket and positioning plate are installed, each fulcrum corresponds to one mounting point, eliminating the need for readjustment of the positioning plate and allowing for the positioning of all fulcrums in one operation, thus improving convenience.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This auxiliary installation tool can assist in positioning, simplify the process of changing the fulcrum, save time and effort, and the fulcrum positioning hole can also provide a limit for the fulcrum, reduce offset during installation, and improve accuracy.

[0020] 2. Two limiting rods abut against the inner sides of the two long beams respectively, and the U-shaped groove of the buckle engages with the short beam of the skid. Fasteners lock the limiting rods onto the long beam of the skid. This design makes the bracket easy to install and provides a good fixing effect.

[0021] 3. The four fulcrum positioning holes are distributed on the same side of the connector, which reduces the area and weight of the positioning plate, making it easier to move and operate the positioning plate.

[0022] 4. The addition of reinforcing rods provides more support for the positioning plate, improving its stability. Attached Figure Description

[0030] Example 1

[0031] A skid fulcrum auxiliary installation tooling, such as Figure 1 As shown, the system includes a bracket 100, a positioning plate 200 located at the top of the bracket 100, and a connector 300 for connecting the bracket 100 and the positioning plate 200. The bracket 100 includes two parallel support rods 110, two limiting rods 120 parallel to the bottom of the support rods 110, and a locking rod 130 connected to the support rods 110. Figure 3 As shown, when the tooling is locked onto the skid, the support rod 110 is placed above the long beam 400 of the skid. The two limiting rods 120 abut against the inner sides of the two long beams 400 of the skid, respectively. The locking rod 130 has a latching part 131 at the end away from the support rod 110. The latching part 131 has a U-shaped groove with an opening facing downwards. The U-shaped groove is engaged with the short beam 500 of the skid. The inner side of the limiting rod 120 is also provided with a fastener 121. In this embodiment, the fastener 121 is a bolt. The limiting rod 120 has a threaded hole 122. The fastener 121 is threadedly connected to the threaded hole 122. One end of the fastener 121 is threaded. The long beam 400 of the sliding skid is pressed against the horizontal plane. The positioning plate 200 is parallel to the horizontal plane and has four fulcrum positioning holes 210. The vertical plane containing the line connecting the midpoints of the two long beams 400 is the first reference plane. Two fulcrum positioning holes 210 are distributed on each side of the first reference plane. The vertical plane containing the line connecting the midpoints of the two short beams 500 is the second reference plane. Two fulcrum positioning holes 210 are distributed on each side of the second reference plane. The fulcrum positioning holes 210 are used to install fulcrums. When the bracket 100 is locked with the skid, the four fulcrum positioning holes 210 are respectively located above the four skid fulcrum mounting parts.

[0032] The working principle of this embodiment is as follows:

[0033] This utility model discloses an auxiliary installation fixture for a skid fulcrum. When replacing the skid fulcrum, the new fulcrum is first inserted into the fulcrum positioning hole 210 from below the positioning plate 200. By rotating the handle of the fulcrum, the locking head of the fulcrum rotates horizontally by 90°, locking the locking head into the positioning plate 200, thereby locking the fulcrum onto the positioning plate 200. Then, the frame is placed on the skid, and the bracket 100 and the skid are locked. The bracket 100 uses the skid itself for positioning, ensuring that the positioning plate 200 is in a horizontal state and that the position of the fulcrum positioning hole 210 is above the skid fulcrum installation part. Since the positioning plate 200 is pre-designed according to the dimensions of the vehicle body, the positioning plate 200 at this time is equivalent to the vehicle body. The position of the fulcrum positioning hole 210 on the positioning plate 200 and the vehicle body are... The locking holes on the fulcrum are in the same position, ensuring that the fulcrum is accurately positioned for vehicle connection. After positioning, the operator locks the fulcrum onto the elongated hole of the fulcrum mounting part. During this process, the fulcrum positioning hole 210 provides a limit for the fulcrum, preventing vibrations from the pneumatic wrench used when fixing the bolts from causing changes in the fulcrum's installation position, resulting in better positioning accuracy. After the bolts are installed, the fulcrum is unlocked, and finally the auxiliary installation tooling is removed, thus completing the positioning and installation of the new fulcrum. This auxiliary installation tooling can assist in positioning, simplifying the fulcrum replacement process compared to existing technologies that require manual measurement, saving more time and effort. At the same time, the fulcrum positioning hole 210 can also provide a limit for the fulcrum, reducing offset during installation and improving accuracy.

[0034] The beneficial effects of this embodiment are as follows:

[0035] This auxiliary installation fixture can assist in positioning, simplifying the process of changing fulcrums and saving time and effort. At the same time, the fulcrum positioning hole 210 can also provide a limit for the fulcrum, reducing offset during installation and improving accuracy. Two limit rods 120 abut against the inner sides of the two long beams 400 respectively, and the U-shaped groove of the buckle part 131 engages with the short beam 500 of the skid. Fasteners lock the limit rods 120 onto the long beam 400 of the skid. This design makes the bracket 100 easy to install, provides good fixation, reduces vibration, and improves the accuracy of fulcrum installation. After the bracket 100 and positioning plate 200 are installed, each fulcrum corresponds to a fulcrum installation part, eliminating the need to readjust the positioning plate 200. The positioning of all fulcrums can be completed in one go, improving convenience.

[0036] In addition, the locking rod 130 and the short beam 500 can also be detachable connections such as threaded connections or pin connections.

[0037] In addition, fastener 121 can also be a buckle set on the limit bar, and fastener 121 is connected to the skid buckle.

[0038] Example 2

[0039] This embodiment is a second embodiment of a skid fulcrum auxiliary installation fixture. This embodiment is similar to the first embodiment, except that, as shown in the following... Figure 4 As shown, there are four fulcrum positioning holes 210, which are distributed at the same end of the connector 300. The vertical plane containing the line connecting the midpoints of the two short beams 500 is used as the second reference plane, and two fulcrum positioning holes 210 are distributed on each side of the second reference plane. When the bracket 100 is installed on the skid, each group of fulcrum positioning holes 210 is located above the corresponding skid fulcrum mounting part, as shown... Figure 2 As shown, the connector 300 includes two connecting rods 310, which are perpendicular to the horizontal plane. The positioning plate 200 has two mounting holes, which are positioned corresponding to the connecting rods. One end of the connecting rod 310 is threaded to one of the support rods 110, and the outer wall of the other end is provided with a limiting part 311. The outer diameter of the limiting part 311 is larger than the diameter of the mounting hole.

[0040] The working principle of this embodiment is as follows:

[0041] After installing the two fulcrums, new fulcrums can be installed and the positioning plate 200 can be flipped so that the two new fulcrums are aligned with the two fulcrum mounting parts on the other side of the connector 300. Compared with the first embodiment, the advantage of this design is that it reduces the area and weight of the positioning plate 200, making it easier to transport and operate. The positioning plate 200 and the connecting rod 310 are detachably connected. The bracket 100 can be fixed on the skid first, and then the mounting hole of the positioning plate 200 can be aligned with the top of the connecting rod 310. The connecting rod 310 can be installed into the mounting hole. The limiting part 311 can limit the height of the positioning plate 200, making installation more convenient and reducing the force required during transportation. At the same time, the tooling is divided into two parts, making it easier to store and improving convenience.
