Detailed Description

In order to make the technical purpose, technical solution and advantageous effects of the present invention clearer, the technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

Example 1:

a rubber base body assembling device of a rubber shock absorber is shown in figures 1-3 and comprises a device vertical frame 1 and a bearing table 2, wherein an assembling seat 3 is installed on the upper table surface of the bearing table 2, and a pressure rod 4 is installed on the device vertical frame 1 below the bearing table 2. The bearing table 2 is provided with at least one assembling hole 5, the flexible inhaul cable 6 can penetrate through the assembling hole 5 from top to bottom, a 3-10mm steel strand can be used as the flexible inhaul cable, the lower end of the flexible inhaul cable 6 is connected with the pressure lever 4, and the upper end of the flexible inhaul cable 6 can extend into the assembling seat and can be sleeved with the rubber substrate 10 at the upper end of the assembling seat; after the pressing rod 4 is pressed down, the pressing rod 4 transmits a downward pulling force to the rubber base body 10 through the flexible inhaul cable 6, and therefore assembly is completed. Specifically, the pressure lever 4 is a bent lever integrally manufactured, and includes a hinged end 41, a force bearing portion 42 and a force application portion 43 which are smoothly and integrally connected in sequence, and the force bearing portion 42 is connected between the hinged end 41 and the force application portion 43. Wherein, hinged end 43 is connected with equipment grudging post 1 through the rotation of hinge bolt, guarantees that whole depression bar 4 can swing around this pin joint. The force application part 43 is a straight rod, and the force application part 43 obliquely extends upwards out of the equipment stand 1, so that a worker can conveniently stand beside the equipment stand 1 to press down the force application part 43. Bearing portion 42 is located the position near region of equipment hole 5 below on the equipment seat just in time to bearing portion 42 is the bending section of bowing downwards, and the welding has pull ring 7 on the bearing portion 42, and the lower extreme of flexible cable 6 is fixed in pull ring 7, and pull ring 7 welded position is close to force application portion 43, guarantees promptly that pull ring 7 locates the one side of equipment hole 5 center pin partially. The advantages of this are: because rubber matrix 10 slope is placed on flange 11 when the equipment bumper shock absorber, one end is high, and one end is low (the one end of keeping away from the pull ring is higher), through locating pull ring 7 one side of equipment hole 5 center pins partially, just can guarantee that flexible cable 6 is the certain angle slant decurrent with equipment hole 5 center pins to the pulling force of rubber matrix 10, and slant decurrent pulling force will more be favorable to flexible cable 6 to draw the higher one end of rubber matrix 10 to the flange below from flange 11's top.

The assembling seat 3 is a cylindrical seat coaxially arranged with the assembling hole 5, namely the assembling seat is hollow, the flexible inhaul cable 6 penetrates through the assembling seat, and the rubber base 10 is just positioned in a hollow cavity of the assembling seat 5 after the rubber base 10 and the flange 11 are assembled. The outer body coupling of lateral wall at the equipment seat 3 upper end has annular top to hold in the palm 31, and the outer body coupling of lateral wall at the equipment seat lower extreme has annular collet 32, and it has the screw hole to distribute along the annular on annular collet 32, offers the thread groove with the screw hole one-to-one on plummer 2, and equipment seat 3 is fixed in the screw hole groove of plummer 2 through the bolt, and stability is high.

The edge of the equipment vertical frame 1 is welded with a hook 8, an upward-arched hooking section 44 is further integrally arranged between the bearing part 42 and the force application part 43, and the hooking section 44 is hung on the hook 8 in the intermittent working and non-working processes.

Of course, besides the force application part 43 of the manual pressing rod 4, a driving part, such as a driving motor, a driving hydraulic cylinder, etc., may be installed on the equipment stand 1, and the driving end of the driving part is hinged to the force application part 43 to drive the pressing rod to swing up and down.

After accomplishing the equipment, flexible cable 6 will move down along with rubber substrate 10, and then drop from assembling 3 inner chambers of seat under the action of gravity, in order to make things convenient for to pull the essence 6 with flexibility between twice equipment and pull to the 3 tops of assembling seat again, install cable spacing ring 9 at the 3 inner walls of assembling seat, as shown in figure 2, figure 3, cable spacing ring 9 is the oval ring form of level setting, the internal diameter of cable spacing ring 9 is in order not to hinder flexible cable 6 as the accuracy, even pass in cable spacing ring 9 is followed to one section of flexible cable 6, and flexible cable 6 is when taut, can not touch cable spacing ring 9. And after the assembly is finished, the upper end of the flexible inhaul cable 6 can be suspended on the inhaul cable limiting ring 9, so that the flexible inhaul cable 6 can be pulled out upwards from the inner cavity of the assembly seat 3 before the next assembly.

Example 2: a rubber base assembling apparatus of a rubber damper of the present embodiment will be explained with respect to points different from those in embodiment 1.

When assembling, the flange 11 is placed on the upper end surface of the annular top support 31 of the assembly seat, so when the end diameter of the rubber base 10 is larger than the inner diameter of the assembly seat 3, the rubber base 10 cannot smoothly enter the cavity of the assembly seat 3, and therefore the assembly of the rubber base 10 cannot be smoothly completed, and if the cavity diameter of the assembly seat 3 is increased, the strength of the assembly seat 3 is reduced.

Therefore, in the present embodiment, the upper end surface of the annular top holder 31 is designed to be a stepped surface, and as shown in fig. 4, the first stepped surface 33 located inside the annular top holder 31 is lower than the second stepped surface 34 located outside the annular top holder, so that an inner cavity with a large diameter can be formed above the first stepped surface 33 while meeting the strength requirement of the assembly base 3. When the diameter of the assembled rubber base 10 is larger than the inner diameter of the assembly hole 5, the inner cavity above the first step surface 33 provides conditions for smooth assembly of the rubber base 10.

Finally, it should be noted that: the above-mentioned embodiments are only used for illustrating but not limiting the technical solution of the present invention, but the protection scope of the present invention is not limited thereto, and any equivalent replacement and modification or partial replacement that do not depart from the spirit and scope of the present invention should be covered within the protection scope of the present invention.
