Technical field

The present invention relates to tire forming vulcanizer modular construction, the anti-displacement of specially a kind of tire forming vulcanizer manipulator Device.

Background technology

Common manipulator machinery positioning non-displacement device is located at manipulator tyre gripper top, using the sleeve on centering rod Forced centering is realized with the cooperation on central authority piston rod top, there is problems with：

1st, manipulator positioning non-displacement device is located at manipulator top, for the hydraulic pressure vulcanizing machine of vertical lift type, Take up room so that whole machine is highly greatly improved, open die height increase, cause the energy and efficiency wave of each opening and closing movement Take.

2nd, the intensity of the complex structure of manipulator positioning non-displacement device and impact manipulator tyre gripper, stability is low, right Middle effect is poor.

3rd, after manipulator positioning non-displacement device is connected with tyre catching apparatus, Jing after multiple bearing, accumulated error is big, centering for centering Precision is low, if there is centering failure, easily produces accident, and manipulator is damaged and causes security incident, and security is poor.

The content of the invention

For the deficiencies in the prior art, the technical problem to be solved is to propose one kind to increase substantially energy-conservation Property, the tire forming vulcanizer manipulator non-displacement device of efficiency, stability, security.

The tire forming vulcanizer manipulator non-displacement device of the technical problem is can solve the problem that, its technical scheme includes resistance Buddhist nun mechanism, except that the damping mechanism is at run-on point between manipulator pivoted arm and crane, including rotating shaft and Bearing block and frictional disk and brake disc, the rotating shaft is installed in bearing block and stretches out bearing block bottom by rolling bearing, The frictional disk is installed on the bottom of bearing block, and the brake disc is coaxially installed in the rotating shaft outside bearing block and is set in rotating shaft The frictional force adjusting part put is pressed on frictional disk.

A kind of structure of the frictional force adjusting part includes base plate, backing plate and spring, and the base plate is installed on rotating shaft On end face, on base plate, the spring is placed between backing plate and brake disc the backing plate, and the base plate is provided with regulation spiral shell Bolt, the regulating bolt passes through backing plate by spring compression on brake disc, and brake disc realizes friction by the thrust that spring is provided The regulation of power and automatically compensation.

To realize the anti-displacement of manipulator fixed point (dress tire and catching tire position), the technological means that can be taken is：In brake disc With the compression region of frictional disk, four friction plate circumference uniform distributions are located at frictional disk, symmetrical two are formed on the brake disc convex Block or circumference uniform distribution form four projections, and the dress tire and catching tire position in manipulator, the projection is pressed together with friction plate.

The damping mechanism can simultaneously at rotating up and down between manipulator pivoted arm and crane, or, it is described Damping mechanism is only at the upper run-on point between manipulator pivoted arm and crane or at lower run-on point.

In mounting structure conventionally, the rotating shaft is installed on manipulator pivoted arm, and the bearing block is installed on crane On.

Beneficial effects of the present invention：

1st, tire forming vulcanizer manipulator non-displacement device of the present invention is arranged on the turned position of manipulator, is not take up master Machine space, especially for mould assembling action vertical lift type vulcanizer is driven, can greatly improve curing efficiency, energy saving.

2nd, present configuration is simple, and itself has no effect to former tire discharging device effect, can also mitigate manipulator rotate into, The vibrations produced and resilience, good stability.

3rd, the present invention applies the function that fixed point frictional force reaches the anti-displacement of manipulator using in turned position, there is no machinery Positioning and positioning failure, will not produce security incident, and security is good.

Specific embodiment

Below in conjunction with the accompanying drawings illustrated embodiment is described further to technical scheme.

Tire forming vulcanizer manipulator non-displacement device of the present invention includes damping mechanism, and the damping mechanism is located at machinery Rotating up and down at position between hand pivoted arm 1 and crane 2, or, damping mechanism is only located at manipulator pivoted arm 1 and crane 2 Between upper rotational position or lower rotational position.

Here, only with located at the damping mechanism of lower rotational position explanation technical scheme：

The damping mechanism includes rotating shaft 3, bearing block 4, frictional disk 5 and brake disc 6, and the socket of the rotating shaft 3 is arranged on machine The lower port of rotary axle box 13 of tool hand pivoted arm 1, the bearing block 4 is arranged on the lower supporting plate of crane 2 by fastening bolt 14 On 15, rotating shaft 3 is installed in bearing block 4 by rolling bearing 7, and the lower end of rotating shaft 3 is stretched out by the bottom through-hole of bearing block 4 Outside bearing block 4, the frictional disk 5 is coaxially installed in the bottom (fixing by fastening bolt 14) of bearing block 4, the brake disc 6 Be set with upwards from the lower end of rotating shaft 3 and contacted with frictional disk 5 (disk at the middle part of brake disc 6 cover into the bottom through-hole of bearing block 4 with Ring cavity between rotating shaft 3 is simultaneously bonded with rotating shaft 3), the lower surface of rotating shaft 3 is provided with frictional force adjusting part and compresses brake disc 6 On frictional disk 5, the diameter of brake disc 6 is less than the diameter of frictional disk 5, as shown in Figure 1.

The frictional force adjusting part includes base plate 8, backing plate 9 and spring 10, and the base plate 8 is arranged on clamping screw 12 In the rotating shaft 3 that the lower surface of rotating shaft 3, the spring 10 and backing plate 9 are set between brake disc 6 and base plate 8 by upper and lower position, Regulating bolt 11 is combined with base plate 8, the top pressure backing plate 9 of the regulating bolt 11 is pressed on spring 10 on frictional disk 5, stress Frictional disk 5 is pressed on upwards the bottom of frictional disk 5 and compresses on the friction plate 5-1 in region, and the size of the thrust of the spring 10 passes through Regulating bolt 11 tighten degree decision, as shown in Figure 1.

The conventional design of the friction plate 5-1 is ring-shaped, but in order to realize that manipulator is determined in dress tire and catching tire position Point friction is spacing, and four friction plate 5-1 are uniformly arranged in the lower circumference of frictional disk 5, corresponding, in the card of brake disc 6 On ride out symmetrical two projection 6-1 (also can circumference uniform distribution ride out four projection 6-1), the dress tire and catching tire position in manipulator Put, the projection 6-1 and friction plate 5-1 is pressed together, in remaining turned position, the projection 6-1 departs from friction plate 5- 1, the non-resistance ease rotation of manipulator pivoted arm 1, as shown in Figure 1, Figure 2 (a), Fig. 2 (b), Fig. 3 (a), Fig. 3 (b) are shown.
