Technical Field

[0001] The utility model relates to the field of automation, in particular to a clip-type top screw pre-installation mechanism. Background Art

[0002] The top screw plays the role of a fastener in the synchronous wheel. It uses the fastening principle of screws and is mainly used in the shaft hole to hold the shaft with the top screw so that it cannot move back and forth.

DETAILED DESCRIPTION

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] Attached Figure 1-2 The utility model is a clip-type top screw pre-installation mechanism, comprising a base 1, a translation assembly 2 arranged on the base 1, a fixed bracket 3 arranged on the base 1 and located above the translation assembly 2, four clips 4 vertically installed on the fixed bracket 3 for storing top screws of different types, a clamp assembly 5 and a mounting assembly 6 arranged at the driving end of the translation assembly 2 and respectively located on both sides of the fixed bracket 3;

[0035] The clips 4 each include a clip body 41 for storing a top screw, and a limiting assembly 42 disposed at the bottom of the clip body 41 for limiting the top screw from falling out of the clip body 41;

[0036] The fixing bracket 3 is provided with four blanking assemblies 7 corresponding to the magazine 4; each blanking assembly 7 is used to drive the limiting assembly 42 so that the top screws in the magazine 4 can fall between the clamp assembly 5 and the mounting assembly 6 one by one.

[0037] Before work: first pre-install different types of top screws into different clips 4, and then vertically install four clips 4 on the fixing bracket 3 respectively. In order to prevent the top screws in the clips 4 from falling from the bottom of the clips 4 during the vertical installation process, a limit assembly 42 is specially set at the bottom of the clips 4.

[0038] During operation: first install the synchronous wheel 9 on the clamp assembly 5 manually or through other automated equipment, then the translation assembly 2 synchronously drives the clamp assembly 5 and the installation assembly 6 to the two sides of the corresponding model of the clip 4, and then the corresponding blanking assembly 7 drives the limit assembly 42, so that the corresponding model of the top screws falls one by one between the clamp assembly 5 and the installation assembly 6, and finally the top screws are installed on the synchronous wheel 9 through the installation assembly 6.

[0039] Further, if Figure 2-4 As shown, the limiting assembly 42 includes a limiting seat 421, a limiting cover 422 located on the top of the limiting seat 421, and a connecting rod unit 423 located between the limiting seat 421 and the limiting cover 422;

[0040] The limiting seat 421 and the limiting cover 422 are provided with four oppositely placed material openings 424;

[0041] The bottom of the limit seat 421 is provided with an avoidance hole 4211 below the material opening 424; the height of the avoidance hole 4211 can only accommodate one top screw; the top of the limit seat 421 is provided with a slide groove 4212 on both sides of the four material openings 424;

[0042] The connecting rod unit 423 includes two limiting plates 4231 rotatably set on the limiting seat 421 and located between adjacent material openings 424, two connecting rods 4232 slidably set in the sliding groove 4212 and movably connected to the two ends of the two limiting plates 4231 respectively, and a reset spring 4233 used to drive the connecting rod 4232 to reset so that the end of the limiting plate 4231 extends into the material opening 424.

[0043] When the clip 4 is in a non-working state, the two connecting rods 4232 are driven by the return springs 4233 to make the two ends of the limiting plates 4231 extend into the material openings 424 on both sides at the same time, thereby playing a limiting role and effectively preventing the top screw from falling.

[0044] When the unloading component 7 drives the limiting component 42: it will drive one of the connecting rods 4232 to overcome the elastic force of the reset spring 4233 and move, so that the two ends of the limiting plate 4231 simultaneously withdraw from the material openings 424 on both sides, so that the top screw in the clip 4 can pass through the material openings 424 and fall into the avoidance hole 4211, which is convenient for the installation of the installation component 6.

[0045] like Figure 4 As shown, the movable connection between the limit plate 4231 and the connecting rod 4232 can be achieved by means of a long hole and a shaft that can be movably matched. Specifically, the connecting rod 4232 is provided with a connecting portion 4234; the connecting portion 4234 is provided with a long groove 4235; both ends of the limit plate 4231 are provided with connecting columns 4236 that extend into the long groove 4235.

[0047] The top of the clamp cover 412 is hinged to the clamp body 41, and the two sides of the lower end are respectively connected to the clamp body 41 buckle 414, which is convenient for quick disassembly and pre-installation of the top screw;

[0048] Further, if Figure 2 As shown, the clamping cover 412 is provided with four observation slots 415 corresponding to the material channel; the width of the observation slots 415 is smaller than the width of the material channel; during operation: the staff can observe the material storage status of the top screw in the material channel through the observation slots 415, so as to facilitate timely replenishment of materials.

[0049] Further, if Figure 5 As shown, the fixed bracket 3 includes a support plate 31 located above the translation assembly 2, and four connecting rods 32 for connecting the base 1 and the support plate 31;

[0051] Further, if Figure 5 As shown, four cavities 33 for installing the magazine 4 are arranged on the top of the fixing bracket 3; a sensor 8 is arranged at the bottom of each cavity 33 for checking whether the magazine 4 is installed in place to avoid material jamming or the phenomenon that the material removal component 7 cannot open the limit component 42.

[0052] Further, if Figure 6 As shown, the translation assembly 2 includes a linear module 21 arranged on the base 1, guide rails 22 arranged on the base 1 and respectively located on both sides of the linear module 21, and a translation seat 23 arranged at the driving end of the linear module 21 and respectively located on the guide rails 22 on both sides; when working: the translation seat 23 is driven by the linear module 21 to simultaneously drive the clamp assembly 5 and the installation assembly 6 to translate. Since the guide rails 22 are arranged on both sides of the linear module 21, the translation seat 23 is more stable during the translation process.

[0053] Further, if Figure 6 As shown, the clamp assembly 5 includes a rotating cylinder 51 arranged on the translation seat 23, a rotating seat 52 arranged at the driving end of the rotating cylinder 51, and clamps 53 respectively located at both ends of the rotating seat 52 for placing products; the clamp assembly 5 in the utility model adopts a double station, one of which is used for installing the top screw, and the other can be used for loading and unloading, which is not only safe to operate but also greatly improves work efficiency; wherein the clamp 53 is the prior art, and a clamp cylinder or an elastic clamp structure can be used to realize the positioning of the synchronous wheel 9. Since the clamp structure is not the innovation of the present application, its structure will not be described in detail.

[0054] Further, if Figure 6 As shown, the mounting assembly 6 includes a slide cylinder 61 arranged on the translation seat 23, a mounting frame 62 arranged at the driving end of the slide cylinder 61, and an electric screwdriver 63 horizontally arranged on the mounting frame 62; when working: first, the head of the electric screwdriver 63 is driven by the slide cylinder 61 to extend into the avoidance hole 4211 to push the top screw toward the mounting hole of the synchronous wheel 9, and then the electric screwdriver 63 is started to install the top screw on the synchronous wheel 9, wherein the diameter of the avoidance hole 4211 is slightly larger than the diameter of the top screw, which can play a guiding role; at the same time, the head of the electric screwdriver 63 is magnetic and can absorb the top screw.
