Description

TECHNICAL FIELD

[0001] The utility model relates to the field of spring assembly technology, and specifically relates to a QC joint automatic assembly tool. BACKGROUND

[0002] In the industrial manufacturing field, as an innovative pipeline connecting device, QC joint (quick connector) has become an ideal choice in many industrial scenes due to its significant advantage of realizing quick connection and disconnection of pipelines without the aid of tools. A kind of QC joint at present is composed of a base (or a limiting sleeve), an O-ring and a joint body. Among them, the bottom end of the joint body is inserted and fixed on the base (or the limiting sleeve is inserted and fixed on the inside of the bottom end of the joint body); the O-ring is arranged between the contact surface of the joint body and the base (or the limiting sleeve), used for sealing the connecting part of the two, effectively preventing fluid leakage.

[0003] With the continuous improvement of industrial automation level, in order to improve the assembly efficiency and consistency of QC joint, a kind of QC joint automatic assembly equipment is put on the market. The QC joint automatic assembly equipment includes a base feeding mechanism, an O-ring feeding mechanism, a joint body feeding mechanism, a dividing disc and a discharging mechanism. Among them, four assembly tools are arranged in a ring shape on the dividing disc, and the assembly tools are used for containing and limiting the base and / or O-ring; the base feeding mechanism, the O-ring feeding mechanism, the joint body feeding mechanism and the discharging mechanism are sequentially arranged on the outside of the dividing disc, and each mechanism is arranged opposite to one of the assembly tools, and the base, the O-ring and the joint body are automatically assembled into a QC joint through the cooperative work of each mechanism, so that the automatic continuous assembly of the QC joint is realized.

[0004] However, the design of the assembly tool of the existing QC joint automatic assembly equipment lacks sufficient flexibility and universality, can only be used for assembling base type QC joint, cannot assemble limiting sleeve type QC joint, and can only adapt to base and O-ring of specific shape and size, so the application range is small. This design defect makes the equipment not capable when facing diversified and customized QC joint production demands. When the enterprise needs to switch to produce limiting sleeve type QC joint or other different models of base type QC joint, a large amount of time and manpower is often consumed to replace and debug the assembly tool, resulting in a significant extension of the production preparation period.

[0005] Under this background, it is necessary to develop a QC joint automatic assembly tool with high universality and flexibility to expand the application range. INVENTION CONTENTS

[0032] The utility model provides a QC joint automatic assembly tool for solving how to expand the application scope of QC joint automatic assembly tool problem.

[0033] As shown in Figure 1 And Figure 2 As shown, Figure 1 It is the sectional view of QC joint automatic assembly tool in the embodiment, the QC joint automatic assembly tool includes main frame body 1, limit post 2 and limit seat 3. Figure 2

Among them, the QC joint assembled by base 8, O type ring 5 and joint main body 7 is called base type QC joint, and the QC joint assembled by limit sleeve 6, O type ring 5 and joint main body 7 is called limit sleeve type QC joint.

[0035] Limit post 2 is installed on main frame body 1 by welding or screwing etc. Limit post 2 includes first sleeve joint part 21, second sleeve joint part 22 and third sleeve joint part 23 successively connected as a whole from top to bottom. First sleeve joint part 21 is adapted with the inner ring of O type ring 5 and is used for the sleeve joint of O type ring 5. Second sleeve joint part 22 is adapted with the inner ring of limit sleeve 6, and second sleeve joint part 22 is used for the sleeve joint of limit sleeve 6 and limits the assembly position of limit sleeve 6. Third sleeve joint part 23 is adapted with the inner ring of the bottom end of joint main body 7, and third sleeve joint part 23 is used for the sleeve joint of the bottom end of joint main body 7.

[0036] Limit seat 3 is installed on main frame body 1. Limit seat 3 has limit slot 31 on it, and limit slot 31 is adapted with base 8, and limit slot 31 is used for placing and limiting base 8.

[0037] ​The QC connector automatic assembly tool of the above technical scheme, when assembling the base type QC connector, first, the base 8 is placed into the limiting groove 31 of the limiting seat 3, then the O-ring 5 is placed into the base 8 of the limiting seat 3, finally, the bottom end of the connector main body 7 is downwardly inserted and pressed on the base 8 of the limiting seat 3, so that the base 8, the O-ring 5 and the connector main body 7 are assembled into one, forming the base type QC connector. When assembling the limiting sleeve type QC connector, first, the limiting sleeve 6 is downwardly sleeved on the second sleeving part 22 along the limiting column 2, then the O-ring 5 is downwardly sleeved on the first sleeving part 21 along the limiting column 2, finally, the bottom end of the connector main body 7 is downwardly sleeved on the third sleeving part 23 along the limiting column 2, in the sleeving process, the second sleeving part 22 can limit the limiting sleeve 6 from moving out of the second sleeving part 22 along with the connector main body 7, and the limiting sleeve 6 can limit the O-ring 5 from moving out of the first sleeving part 21 along with the connector main body 7, so that the limiting sleeve 6, the O-ring 5 and the connector main body 7 are assembled into one, forming the limiting sleeve type QC connector. It can be seen that, compared with the prior art, the utility model not only can be used for assembling the base type QC connector, but also can be used for assembling the limiting sleeve type QC connector, effectively expanding the application range of the QC connector automatic assembly tool.

[0038] The first sleeving part 21 and the third sleeving part 23 are both in cylindrical shape, the diameter of the first sleeving part 21 is slightly smaller than the inner diameter of the O-ring 5, and the diameter of the third sleeving part 23 is slightly smaller than the inner diameter of the bottom end of the connector main body 7, so as to smoothly pull out the limiting column 2 after assembling into the QC connector. The second sleeving part 22 is in circular truncated cone shape, so that the second sleeving part 22 not only can be sleeved by the limiting sleeve 6, but also can limit the limiting sleeve 6 from moving downwardly on the third sleeving part 23 along with the connector main body 7 through the outer peripheral inclined surface.

[0039] Referring to Figure 1 In an embodiment of the limiting column 2 and the limiting seat 3, the number of the limiting column 2 and the limiting seat 3 is at least two. The size and / or shape of each limiting column 2 is different from each other, and the size and / or shape of each limiting groove 31 is different from each other. In this way, the QC connector automatic assembly tool can be adapted to limit different models and specifications of the O-ring 5, the limiting sleeve 6 and the connector main body 7 through the plurality of different limiting columns 2, so as to be used for producing the limiting sleeve type QC connector of different models and specifications; and can be adapted to limit different models and specifications of the base 8 through the plurality of different limiting grooves 31, so as to be used for producing the base type QC connector of different models and specifications, thereby further improving the application range of the QC connector automatic assembly tool.

[0040] The size and shape of each limiting column 2 or limiting groove 31 can also be the same, so as to simultaneously produce a plurality of the same model of the limiting sleeve type QC connector or the base type QC connector, improving the production efficiency.

[0041] Referring to Figure 2As shown, on the basis of the above embodiments, the limiting column 2 and the limiting seat 3 are installed on the main frame body 1 in a detachable manner such as screwing or clamping. In this way, this detachable mounting manner can facilitate the replacement of limiting columns 2 and limiting seats 3 of different shapes and sizes according to production needs, thereby facilitating the assembly of limiting sleeve type QC joints and base type QC joints of different specifications, and further improving the application range of the QC joint automatic assembly tool.

[0042] Referring to Figure 1 and Figure 2 As shown, on the basis of any of the above embodiments, a step surface 4 is provided between the second sleeve connecting portion 22 and the third sleeve connecting portion 23. The step surface 4 is used to abut against the bottom surface of the limiting sleeve 6 to limit the assembly position of the limiting sleeve 6. In this way, the step surface 4 can assist the second sleeve connecting portion 22 to further limit the assembly position of the limiting sleeve 6, effectively preventing the limiting sleeve 6 from moving downward with the joint body 7 to the third sleeve connecting portion 23, thereby improving the assembly effect; it can also prevent the limiting sleeve 6 from being clamped on the second sleeve connecting portion 22 under the action of the applied downward pressure.

[0043] Referring to Figure 1 and Figure 2 As shown, in one embodiment of the main frame body 1, the main frame body 1 includes a mounting frame 11 and a movable frame 12. The movable frame 12 is vertically slidingly connected to the mounting frame 11. The mounting frame 11 is used to be installed on the index plate 9 of the QC joint assembly equipment. An elastic member (not shown in the figure) is connected between the movable frame 12 and the mounting frame 11. The elastic member has a spring force that drives the movable frame 12 to move vertically upward. In this way, during the assembly or pressing of the limiting sleeve 6, the O-ring 5 and the joint body 7, or during the assembly or pressing of the base 8, the O-ring 5 and the joint body 7, if the downward pressure received by the QC joint automatic assembly tool exceeds the spring force of the elastic member, the movable frame 12 can slide downward against the spring force of the elastic member, effectively preventing the QC joint automatic assembly tool from being damaged by overpressure, thereby prolonging the service life of the QC joint automatic assembly tool; when the assembly or pressing is completed, the QC joint automatic assembly tool is no longer under pressure, at this time, the elastic member can drive the movable frame 12 to slide upward to return to the original position, so as to facilitate the subsequent feeding of the next part or the grabbing and transferring of the QC joint. The elastic member can also prevent the movable frame 12 from sliding downward and separating from the mounting frame 11 under its own gravity.

[0044] The above-mentioned elastic member can use existing springs or elastic bands.

[0045] Referring to Figure 1As shown in the above embodiment, the main frame body 1 further comprises a baffle 13. The baffle 13 is fixed on the mounting frame 11 by screwing or integral connection. When the movable frame 12 is not pressed, the movable frame 12 abuts against the baffle 13 under the elastic force of the elastic member. In this way, the baffle 13 can limit the limit position of the upward sliding of the movable frame 12, i.e. limit the original position of the movable frame 12, so as to avoid affecting the subsequent feeding of the next part or the grabbing and transferring of the QC joint.

[0046] Referring to Figure 1 and Figure 2 As shown in any of the above embodiments, the limiting column 2 further comprises a circular table-shaped guide portion 24. The guide portion 24 is integrally connected with the top end of the first sleeve portion 21. The diameter of the guide portion 24 gradually decreases from bottom to top, and the guide portion 24 is used to guide the O-ring 5, the limiting sleeve 6 and the joint body 7 to be sleeved on the limiting column 2. The slot of the limiting groove 31 is provided with a gradually expanding port 32, the diameter of the gradually expanding port 32 gradually increases from bottom to top, and the gradually expanding port 32 is used to guide the base 8 to be inserted into the limiting groove 31. In this way, the guide portion 24 can guide the O-ring 5, the limiting sleeve 6 and the joint body 7 to be smoothly sleeved on the limiting column 2, and the gradually expanding port 32 can guide the base 8 to be smoothly inserted into the limiting groove 31, both of which can play a guiding role, facilitating the assembly of the QC joint.

[0047] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
