Embodiment 1

[0025] Such as Figure 1-2 As shown, an explosion-proof indexing turntable includes a positioning device and an indexing plate 8. Several evenly distributed positioning grooves are arranged on the circumference of the indexing plate 8. The positioning device includes a positioning bead 4 and is used for fixing The support of the positioning bead 4, the axis of the length direction of the positioning bead 4 is perpendicular to the axis of the indexing plate 8, the positioning bead 4 is used to be embedded in the positioning groove, the swing cylinder 1 adopts a pneumatic swing cylinder, and the swing cylinder 1 is detachable The connection method is fixed on the base 3; the transmission mechanism includes a ratchet 2 and a flange 5, the flange 5 is in a T-shaped shape, the ratchet 2 is connected to the swing cylinder 1 with a rotating shaft, and the ratchet 2 and the flange 5 adopt a shaft and a hole The shaft of the swing cylinder 1, the ratchet 2, and the flange 5 coincide wi...

Embodiment 2

[0028] Present embodiment makes further technical scheme on the basis of embodiment 1: as Figure 3-6 As shown, an annular protruding ring 9 is provided on the circumference of the indexing plate 8, and the cross section of the protruding ring 9 along the radial direction of the indexing plate is concave arc-shaped, and several evenly distributed holes are arranged on the surface of the protruding ring 9 The positioning groove, the connection between the positioning groove and the convex ring 9 is a circular arc curve, so that during the process of the positioning bead 4 being embedded into the positioning groove from the edge of the indexing plate 8, the relationship between the positioning bead 4 and the indexing plate is stable and has no impact. It is beneficial to the accuracy of positioning. Through experimental comparison, it is determined that the depth of the positioning groove is 2-3mm, and if it is less than 2mm, the positioning beads 4 cannot effectively prevent the...

Embodiment 3

[0030] This embodiment is further limited on the basis of Embodiment 1. The swing cylinder adopts a pneumatic swing cylinder with few electrical components, and the indexing can be realized through the cooperation of the index plate and the positioning beads. Compared with the prior art, the structure is simple and the The cost and the difficulty of equipment control are reduced, and it can be used in most places where explosion-proof and explosion-proof are required.

Abstract

The invention aims to provide an explosion-proof indexing plate. The explosion-proof indexing plate comprises a positioning device and a indexing plate body, wherein a plurality of positioning groovesare distributed in the circumference of the indexing plate body, the positioning device comprises positioning beads and a support used for fixing a positioning bead, wherein the positioning bead is used for being embedded into the positioning grooves so as to apply rotary damping to the indexing plate body through the positioning bead to position the indexing plate body. According to the explosion-proof indexing plate, a pneumatic type swing cylinder is adopted through a power source, electrical components are few, the indexing can be realized through cooperation of the indexing plate body and the positioning bead, compared with the prior art, the cost is reduced, the equipment control difficulty is reduced, and the explosion-proof indexing plate can be used for most places needing anti-explosion and isolation explosion; the workbenches with different specifications can be installed on the dividing plate body, so that the universality of the explosion-proof indexing plate can be realized; and in addition, a plurality of stations such as four-station, six-station, eight-station and the like can be realized by changing the number of the positioning grooves of the index plate and changing the rotating angle of the swing cylinder.

Description

technical field [0001] The invention relates to the field of automatic production of pyrotechnics, in particular to an explosion-proof indexing turntable. Background technique [0002] In the field of automated production, the rotation of the workpiece and the multi-station turntable are often involved, such as the rotary table used for the surface quality inspection of the workpiece, especially in the pyrotechnics industry. When using automation equipment, the first consideration is safety. The problem is that the electrical components used must be explosion-proof. When the positioning accuracy of the equipment is not high, using an explosion-proof servo motor or directly using a pneumatic indexing plate to achieve indexing will not only cost too much, but also increase the difficulty of overall control of the equipment. Contents of the invention [0003] The purpose of the present invention is to provide an explosion-proof indexing turntable. The technical problem to be...
