Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology for the maintenance of universal joints in rail vehicles, and in particular to a universal joint flange grinding support device. Background Technology

[0002] The universal joint flange of the CRH5A platform EMU suffers from surface defects such as bumps and scratches during EMU operation, flange transportation, and flange disassembly. Currently, grinding is used to treat these defects. However, grinding requires placing the flange on a workbench and flexibly adjusting its position and orientation to facilitate grinding different parts of the flange. The universal joint flange has an irregular shape, with one side being a disc-shaped structure and the other side being a lug plate connecting the universal joint. The lug plate and the disc form a right angle structure. Currently, operators place the flange directly on the table during grinding. Although the position and orientation of the flange can be flexibly adjusted at any time, the flange is in a free and unrestrained state on the table. Whether storing, picking up, or grinding, the flange is prone to falling to the ground, posing a safety hazard. Due to the special structure of the flange, how to provide a universal joint flange grinding support device has become an important technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0003] The purpose of this invention is to overcome the defects of the existing technology and provide a universal joint flange grinding support device to solve the problems of insufficient positioning and safety during existing flange grinding.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] This utility model discloses a universal joint flange grinding support device, comprising:

[0006] A worktable, a first limiting shaft that can be inserted into the shaft hole of the workpiece to be ground and can be separated from the worktable; and

[0007] A second limiting axis is provided perpendicular to the first limiting axis and movably connected to both ends of the worktable;

[0008] A limiting seat is fixedly connected to the worktable below the second limiting shaft. A labyrinth path is formed between the limiting seat and the worktable surface, and between the limiting seat and the second limiting shaft, to limit the radial displacement of the first limiting shaft, so as to adjust the grinding posture and position of the workpiece.

[0009] Furthermore, both ends of the first limiting shaft are provided with shoulders placed outside the limiting seat, and the diameter of the shoulders is greater than the width of the maze path.

[0010] Furthermore, the maze path includes a lower limit slide and an upper limit slide arranged parallel to the lower limit slide;

[0012] Furthermore, it also includes: a barrier structure disposed at both ends of the limiting seat and connected to the second limiting shaft, for preventing the first limiting shaft from displacing axially and radially along the table surface at the inlet and outlet positions.

[0013] Furthermore, the enclosure structure includes a first baffle and a second baffle;

[0014] The workbench is fixedly connected to the first baffle at the end corresponding to the limiting seat, and the workbench is fixedly connected to the outer side corresponding to the end of the limiting seat.

[0015] The top of the first baffle has a mounting groove for mounting the second limiting shaft.

[0016] Furthermore, one end of the second limiting shaft is rotatably connected to the mounting groove via a shaft, and the other end is plugged into and unplugged into the mounting groove via a plug-in structure.

[0036] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0037] See Figure 1 , 2As shown;

[0038] A utility model discloses a universal joint flange grinding support device, comprising:

[0039] The worktable 1, the first limiting shaft 2 which is able to be installed on the shaft hole of the workpiece to be ground 15 and can be separated from the worktable 1, and the second limiting shaft 6 which is perpendicular to the first limiting shaft 2 and movably connected to both ends of the worktable 1;

[0040] A limiting seat 3 is fixedly connected to the worktable 1 below the second limiting axis 6. A labyrinth path is formed between the limiting seat 3 and the worktable 1 surface, and between the limiting seat 3 and the second limiting axis 6, to limit the radial displacement of the first limiting axis 2, so as to adjust the grinding posture and position of the workpiece 15 to be ground.

[0041] Specifically, in this structure, the worktable 1 is used to support the workpiece 15 to be ground and the first limiting shaft 2. The workpiece 15 is a universal joint flange as in the prior art. The first limiting shaft 2 can be installed on the shaft hole of the workpiece 15. Two limiting seats 3 are symmetrically fixed on the table surface of the worktable 1. A lower limiting slide 100a is formed between the lower part of the limiting seat 3 and the table surface of the worktable 1. A second limiting shaft 6 is movably connected to the upper part of the limiting seat 3 on the worktable 1. An upper limiting slide 100b is formed between the upper part of the limiting seat 3 and the second limiting shaft 6. A maze path is formed by the lower limiting slide 100a and the upper limiting slide 100b to limit the displacement of the first limiting shaft 2. During grinding, this prevents the first limiting shaft 2 from axially moving. The first limiting shaft 2 can move radially along the table surface within the maze path to facilitate adjustment of the grinding posture and position of the workpiece 15 on the first limiting shaft 2.

[0042] Preferably, both ends of the first limiting shaft 2 are provided with shoulders located outside the limiting seat 3. The diameter of the shoulder is greater than the width of the maze path, that is, the diameter of the shoulder is greater than the height of the lower limiting slide 100a and the upper limiting slide 100b. Thus, the inner surface of the shoulder contacts the limiting seat 3 and the side of the second limiting shaft 6, thereby preventing the first limiting shaft 2 from axial displacement and avoiding the first limiting shaft 2 from slipping off from both ends of the worktable. It can only move radially along the tabletop within the lower limiting slide 100a and the upper limiting slide 100b. The shoulder can be integrally formed with the first limiting shaft 2, or it can be detachably fixedly connected by a connector.

[0043] Preferably, the maze path includes a lower limit slide 100a and an upper limit slide 100b arranged parallel to the lower limit slide 100a. One end of the lower limit slide 100a is formed with an inlet / outlet 200 into which a first limiting shaft 2 can be inserted or removed. The inlet / outlet 200 is connected to the upper limit slide 100b.

[0044] Specifically, a lower limiting slide 100a is formed between the lower surface of the end of the limiting seat 3 and the upper surface of the worktable 1, and an upper limiting slide 100b is formed between the upper surface of the limiting seat 3 and the second limiting shaft 6. One end of the lower limiting slide 100a is connected to the upper limiting slide 100b through the inlet and outlet 200.

[0045] See Figure 2 The following is stated:

[0046] The universal joint flange grinding support device also includes a barrier structure set at both ends of the limiting seat 3 and connected to the second limiting shaft 6, which is used to prevent the first limiting shaft 2 from moving axially and radially along the table surface at the inlet / outlet 200 position.

[0047] Specifically, a baffle structure is provided on the workbench 1 at the corresponding inlet / outlet 200 position. The length of the second limiting shaft 6 is greater than the length of the limiting seat 3, and the second limiting shaft 6 and the baffle structure are detachably and movably connected above the limiting seat 3. In use, the second limiting shaft 6 is removed, and the first limiting shaft 2 can be inserted or removed through the inlet / outlet 200. The baffle structure is used to prevent the first limiting shaft 2 from moving axially or radially along the table surface at the inlet / outlet 200 position. In other words, the first limiting shaft 2 can only be removed in the vertical direction, preventing the first limiting shaft 2 from falling from the side of the workbench 1 at the inlet / outlet 200 position and the workpiece 15 to be ground from slipping off, thus ensuring safety during use.

[0048] See Figure 2-4 As shown:

[0049] The enclosure structure includes a first baffle 4 and a second baffle 5;

[0050] A first baffle 4 is fixedly connected to the end of the worktable 1 corresponding to the limit seat 3. The first baffle 4 blocks the radial displacement of the first limit shaft 2 and prevents the first limit shaft 2 from falling off the side of the worktable 1. A second baffle 5 is fixedly connected to the outer side of the end of the worktable 1 corresponding to the limit seat 3. The second baffle 5 blocks the axial displacement of the first limit shaft 2 and prevents the first limit shaft 2 from falling off both ends of the worktable 1.

[0051] The top of the first baffle 4 has a mounting groove 300 for mounting the second limiting shaft 6;

[0052] Specifically, the first baffle 4 includes two, and a mounting groove 300 for mounting the second limiting shaft 6 is formed between the two first baffles 4. One end of the second limiting shaft 6 is rotatably connected to the mounting groove 300 via a shaft, and the other end is plugged into and unplugged connected to the mounting groove 300 via a plug-in structure.

[0053] In another preferred embodiment, the first baffle 4 may also be a single baffle (not shown), the first baffle 4 is arranged perpendicular to the second limiting shaft 6, and the top of the first baffle 4 is provided with a U-shaped mounting groove 300.

[0054] See Figure 2 , 5 As shown:

[0055] Preferably, one end of the second limiting shaft 6 is rotatably connected to the mounting groove 300 via a shaft, and the other end is plugged into and unplugged connected to the mounting groove 300 via a plug-in structure.

[0056] The plug-in structure includes a plug-in channel 12 formed in the mounting groove 300 and a telescopic pin 7 installed at the end of the second limiting shaft 6. The pin 7 and the plug-in channel 12 are plugged in and out.

[0057] See Figure 5 As shown, a blind hole is provided at one end of the second limiting shaft 6. A pin 7 and a compression spring 8 for driving the pin 7 to extend are installed in the blind hole. A sliding groove 10 is provided on the second limiting shaft 6 corresponding to the blind hole. The second limiting shaft 6 is slidably connected to the sliding groove 10 through a positioning member 9. The positioning member 9 can be a positioning pin or bolt that passes through the second limiting shaft 6. The positioning member 9 cooperates with the sliding groove 10 to prevent the pin 7 from disengaging from the second limiting shaft 6. In use, driving the positioning member 9 can push the pin 7 back into the blind hole, thereby disengaging it from the insertion hole.

[0058] See Figure 4 As shown, two crossbeams 11 are fixedly connected to the top of the mounting groove 300, and an insertion channel 12 is formed between the two crossbeams 11. The crossbeams 11 pass through the first baffle 4. The crossbeams 11 can be bolts or pins in the prior art, or they can be fixed pins welded in the mounting groove 300, as long as they can form an insertion channel 12 that can be plugged and pulled into the pin 7.

[0059] To further improve safety, preferably, a guard plate 14 is fixedly connected to the edge of the workbench 1 at the inlet / outlet 200. The guard plate 14 protrudes from the workbench 1 to further prevent the first limiting shaft 1 from sliding off from both sides of the workbench.

[0060] See Figure 1 As shown:

[0061] Preferably, both ends of the limiting seat 3 are provided with lower limiting slides 100a, and both ends of the worktable 1 are fixedly connected with a guard structure corresponding to the limiting seat 3, so that the worktable 1 can be used from both sides.

[0062] See Figure 1 As shown:

[0063] Preferably, casters 13 are installed at the four corners of the bottom of the workbench 1. The casters 13 have a braking device. When in use, the workbench is moved around the work site by the casters 13.

[0064] In the above technical solution, the universal joint flange grinding support device provided by this utility model has the following usage method:

[0065] First, the part to be polished 15 is mounted on the first limiting shaft 2;

[0066] Secondly, with the second limiting shaft 6 in the open state, the first limiting shaft 2 is inserted into the limiting slide 100 through the inlet and outlet 200;

[0067] Close the second limiting shaft 6, rotate the second limiting shaft 6, move the positioning piece 9, the pin 7 retracts into the second limiting shaft 6, aligns with the insertion channel 12 formed by the first baffle 4, release the positioning piece 9, under the action of the spring 8, the pin 7 extends and inserts into the insertion channel 12, and the second limiting shaft 6 closes the inlet and outlet 200.

[0068] When sanding, see Figure 1 As shown, the first limiting shaft 2 can be radially displaced along the tabletop within the lower limiting slide 100a. (See also...) Figure 2 As shown, the workpiece can also be adjusted to polish by radial displacement along the table within the upper limit slide 100b, thereby utilizing the support device. The workpiece 15 can be polished by adjusting its posture and position 360° around the first limit axis 2 within the maze path.
