Description

Technical Field

[0001] This application relates to the technical field of profile processing, and in particular to a tooling for manually operated profile milling. Background Technology

[0002] Reference Figure 1 A passenger vehicle shell panel includes a panel body that is arc-shaped. Two limiting plates are connected parallel to each other along the length of the inner arc wall of the panel body. Bending plates are provided along the length of the limiting plates on the side away from the panel body, and the two bending plates are located on the side of the two limiting plates that are close to each other.

[0003] Currently, when connecting the outer shell panels of a bus, bolts for connection need to be placed between two limiting plates. However, since the diameter of the bolt head is larger than the distance between the two bending plates, during the placement of the bolt, it is necessary to insert the bolt from one end of the two limiting plates into the space between the two limiting plates and the two bending plates, and then slide the bolt to the appropriate position between the two limiting plates for installation.

[0004] Regarding the aforementioned technologies, the inventors believe that during the installation of bolts on the bus body panels, each bolt needs to be inserted and slid to a specific position one by one, which makes the bolt installation inconvenient and inefficient. Utility Model Content

[0005] To facilitate bolt installation and improve bolt installation efficiency, this application provides a profile milling fixture for manual operation.

[0006] The technical solution of the profile milling fixture for manual operation provided in this application is as follows:

[0007] A tooling for manually operated profile milling includes a sliding block, a mounting plate, a connecting rod, and a drill rod. The sliding block is arranged parallel to the mounting plate. Several connecting rods are connected parallel to each other between the mounting plate and the sliding block. The mounting plate has a first rotating opening, and the sliding block has a second rotating opening corresponding to the first rotating opening. A sliding groove is formed on the side of the sliding block away from the mounting plate. The drill rod passes through both the first rotating opening and the second rotating opening. A drill bit is provided on the side of the drill rod that extends into the sliding groove.

[0008] By adopting the above technical solution, a sliding block is slidably placed outside two limiting plates, which are set in sliding grooves. The sliding block is slid to a suitable position on the limiting plates, and the drill rod is connected to an external drive source. The drill bit at the end of the drill rod drills a hole in the bent plate. When installing bolts, the bolts are directly placed between the two limiting plates from the drilled hole, facilitating bolt placement and installation. Through the cooperation of the sliding block, mounting plate, connecting rod, and drill rod, rapid and accurate drilling of the bent plate is achieved, which facilitates bolt installation and improves bolt installation efficiency.

[0009] Optionally, a fixing block is provided in the sliding groove. The fixing block is slidably disposed between the two limiting plates. The width of the fixing block is equal to the distance between the two limiting plates. The fixing block and the sliding block are connected by bolts.

[0010] By adopting the above technical solution, the fixing block is placed between the two limiting plates, and the sliding block and the fixing block are locked together with bolts, thus fixing the sliding block and reducing the possibility of the sliding block shaking during drilling.

[0011] Optionally, the sliding block has a guide hole communicating with the sliding groove, a guide rod is slidably disposed in the guide hole, and the fixed block has an alignment hole corresponding to the end of the guide rod, the end of the guide rod being inserted into the alignment hole.

[0012] By adopting the above technical solution, the guide rod is inserted into the alignment hole of the fixed block, thereby limiting the position of the fixed block and facilitating the fixation of the fixed block and the sliding block in subsequent operations. When the sliding block is slidable, the fixed block can move along with the sliding block via the guide rod.

[0013] Optionally, a connecting ring is connected to the guide rod on the rod segment of the sliding groove, and an elastic element is provided between the connecting ring and the inner bottom wall of the sliding groove. In its natural state, the end of the guide rod is embedded in the corresponding alignment hole under the action of the elastic element.

[0014] By adopting the above technical solution, the connecting ring and connecting spring ensure that the guide rod is always embedded in the alignment hole on the fixed block when the sliding block slides on the limiting plate, reducing the possibility of the guide rod coming out of the alignment hole.

[0015] Optionally, a positioning rod is provided at the end of the drill bit away from the drill rod, and a positioning hole corresponding to the positioning rod is provided on the fixing block, and the positioning rod is inserted into the positioning hole.

[0016] By adopting the above technical solution, the positioning rod is inserted into the positioning hole during drilling, which realizes the positioning of the drill rod and reduces the possibility of the drill rod shaking during the drilling process.

[0017] Optionally, an abutting roller is rotatably provided on each of the two opposing inner walls of the sliding groove, and the distance between the two abutting rollers is equal to the distance between the two limiting plates away from each other's side walls.

[0018] By adopting the above technical solution, the abutting roller is fitted with the two limiting plates, which reduces the wear on the limiting plates during the movement of the sliding block, facilitates the movement of the sliding block, and reduces the possibility of damage to the limiting plates.

[0019] Optionally, a support rod is provided on one side of the sliding block, and the support rod abuts against the inner arc wall of the plate body.

[0020] By adopting the above technical solution, while drilling, the support rod is supported on the inner arc wall of the plate body, which realizes the support of the sliding block, further reduces the possibility of the sliding block shaking during the drilling process, and improves the stability of the structure.

[0021] Optionally, an abutment plate is provided at the end of the support rod away from the sliding block, and the abutment plate abuts against the inner arc wall of the plate body.

[0022] By adopting the above technical solution, the abutment plate is set at the end of the support rod, which reduces the pressure of the support rod on the plate body and reduces the possibility of deformation of the plate body during drilling.

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

[0024] 1. Through the cooperation of sliding blocks, mounting top plates, connecting rods and drill rods, rapid and accurate drilling of bent plates is achieved, which facilitates the installation of bolts and improves the efficiency of bolt installation;

[0025] 2. The positioning rod and positioning hole enable the positioning of the drill rod, reducing the possibility of the drill rod shaking during the drilling process;

[0026] 3. The abutment plate reduces the pressure of the support rod on the plate body, thus reducing the possibility of deformation of the plate body during drilling. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be further described in detail below. Embodiments of this application provide a tooling for manually operated profile milling, which facilitates bolt installation and improves bolt installation efficiency.

[0033] Reference Figure 2 and Figure 3 A tooling for manually operating profile milling includes a sliding block 1, a mounting plate 2, a connecting rod 3, a drill rod 4, and a fixing block 5. The sliding block 1 is arranged parallel to the mounting plate 2, and several connecting rods 3 are arranged parallel to the sliding block 1 and the mounting plate 2. The connecting rods 3 are also arranged perpendicular to both the sliding block 1 and the mounting plate 2.

[0034] Reference Figure 3 and Figure 4A sliding groove 101 is formed along the length of the sliding block 1 on the side away from the mounting top plate 2, and the sliding groove 101 passes through the opposite ends of the sliding block 1. Abutment rollers 6 are rotatably connected to the two opposite inner walls of the sliding groove 101, and the distance between the two abutment rollers 6 is equal to the distance between the two limiting plates 02 away from each other's side walls. A first rotating opening 21 is formed on the mounting top plate 2, and a first rotating bearing 7 is installed in the first rotating opening 21. A second rotating opening 102 is formed on the sliding block 1, communicating with the sliding groove 101, and a second rotating bearing 8 is installed in the second rotating opening 102. The first rotating opening 21 and the second rotating opening 102 are coaxially arranged. The drill rod 4 is slidably disposed in the first rotating opening 21, and a drill bit 9 is connected to the end of the drill rod 4 near the sliding block 1. The drill bit 9 is slidably disposed in the second rotating opening 102.

[0035] Reference Figure 3 and Figure 4 A fixing block 5 is disposed in the sliding groove 101, and the width of the fixing block 5 is equal to the distance between the two limiting plates 02 on their respective sides. Two alignment holes 51 are formed on the top surface of the fixing block 5, and two guide holes 103 communicating with the sliding groove 101 are formed on the sliding block 1. The two guide holes 103 correspond one-to-one with the two alignment holes 51. A guide rod 10 is slidably disposed in each guide hole 103, and a connecting ring 11 is fixedly connected to the rod segment of the guide rod 10 located in the sliding groove 101. A connecting spring 12 is sleeved on the guide rod 10, one end of which is connected to the inner bottom wall of the sliding groove 101, and the other end is connected to the connecting ring 11. In its natural state, the end of the guide rod 10 is embedded in the corresponding alignment hole 51 under the action of the connecting spring 12. The sliding block 1 has two first bolt holes 104 that communicate with the sliding groove 101, and the fixing block 5 has two second bolt holes 52. The two first bolt holes 104 and the two second bolt holes 52 are arranged in a one-to-one correspondence. The bolt passes through the first bolt hole 104, through the sliding block 1, and is threaded to the fixing block 5 through the second bolt hole 52. An anti-slip pad 13 is provided on the side of the fixing block 5 near the inner wall of the sliding groove 101.

[0036] Reference Figure 3 and Figure 4 A positioning rod 14 is coaxially connected to the end of the drill bit 9 away from the drill rod 4. A positioning hole 53 corresponding to the positioning rod 14 is provided on the fixing block 5, and the end of the positioning rod 14 is embedded in the positioning hole 53. A support rod 15 is fixedly connected to one side of the sliding block 1. The end of the support rod 15 away from the sliding block 1 is connected to an abutment plate 16 by a countersunk bolt. The abutment plate 16 is fitted against the inner arc wall of the plate body 01.

[0037] Reference Figure 3 and Figure 4When processing the bus shell panels, the sliding block 1 is mounted outside the two limiting plates 02, and the two abutting rollers 6 abut against the opposite sides of the two limiting plates 02. The fixing block 5 is pushed between the two limiting plates 02 and moved below the sliding block 1. The guide rod 10 is pulled up, and the position of the fixing block 5 is adjusted so that the two alignment holes 51 on the fixing block 5 correspond one-to-one with the two guide rods 10. At this time, the guide rod 10 is released, and the guide rod 10 is embedded in the corresponding alignment hole 51 under the action of the connecting spring 12, thus limiting the position of the fixing block 5. A bolt is passed through the first bolt hole 104 and threadedly connected to the second bolt hole 52 on the fixing block 5. The top surface of the fixing block 5 abuts against the bending plate 03, thereby locking the position of the sliding block 1 and the fixing block 5. The anti-slip pad 13 increases the friction between the fixed block 5 and the bending plate 03, reducing the possibility of the sliding block 1 slipping on the limiting plate 02 during the fixing process. The guide rod 10 and connecting spring 12 allow the fixed block 5 to move along with the sliding block 1 during position adjustment, facilitating subsequent positioning of the fixed block 5 and the sliding block 1. The connecting spring 12 reduces the possibility of the guide rod 10 dislodging from the alignment hole 51 during the movement of the sliding block 1.

[0038] Reference Figure 3 and Figure 4 After defining the position of the sliding block 1, one end of the drill rod 4 is connected to an external drive source, causing the drill rod 4 to rotate and the drill bit 9 to drill a hole in the bent plate 03. The positioning rod 14 is inserted into the positioning hole 53 on the fixed block 5, which helps reduce the possibility of the drill rod 4 shaking during drilling. The support rod 15 supports the plate body 01, further reducing the possibility of the sliding block 1 shaking during drilling. The abutment plate 16 reduces the pressure of the support rod 15 on the plate body 01, reducing the possibility of deformation of the plate body 01 during drilling. The abutment roller 6 abuts against the limiting plate 02, facilitating smoother sliding of the sliding block 1 on the limiting plate 02. By drilling holes at appropriate positions on the bent plate 03, bolts can be directly inserted between the two limiting plates 02 through the drill holes, which helps improve the connection efficiency of the bolts.

[0039] The implementation principle of a profile milling fixture for manual operation in this application embodiment is as follows: When processing the outer shell sheet of a bus, the sliding block 1 is set up outside the limiting plate 02, the fixing block 5 is pushed between the two limiting plates 02, and the bolt is passed through the first bolt hole 104 and threadedly connected to the second bolt hole 52 on the fixing block 5. The top surface of the fixing block 5 abuts against the bending plate 03, thereby locking the position of the sliding block 1 and the fixing block 5.

[0040] After defining the position of the sliding block 1, one end of the drill rod 4 is connected to an external drive source, causing the drill rod 4 to rotate and the drill bit 9 to drill a hole in the bent plate 03. By drilling a hole at a suitable position on the bent plate 03, bolts can be directly inserted between the two limiting plates 02 through the drill hole, which helps to improve the connection efficiency of the bolts.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
