Description

Technical Field

[0002] The existing socket is provided with several plugs, and the adjacent two plugs are arranged at equal intervals, or it can be considered that the socket is provided with several plugs distributed at equal intervals. In the prior art, in order to realize the variable pitch between adjacent two plugs, one plug is moved at a time. After the first plug is moved to the corresponding position, then the next plug is continued to be moved until all the plugs are moved in place to realize the variable pitch effect between all the plugs. This processing method results in low processing efficiency. Content of the Utility Model

[0003] The main technical problem to be solved by the utility model is to provide a variable pitch mechanism.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a variable pitch mechanism, which includes:

[0005] A frame, the frame is provided with an upper fixed cavity, the upper fixed cavity is provided with a chute, and several limit pieces are accommodated in the chute;

[0006] Several plugs, the plugs are accommodated in the upper fixed cavity, the plugs are provided with a chamber opening downward, one end of the limit piece extends into the chamber of one of the plugs, and the other end of the limit piece extends into the chamber of the adjacent plug;

[0007] A first driving mechanism, the first driving mechanism includes a driving block, the driving block extends into the chamber of the outermost plug, and the first driving mechanism drives the outermost plug to move.

[0008] With this structural arrangement, during use, after the plugs are fixed in the upper fixed cavity, the first driving mechanism works, the driving block drives the outermost plug to move, and under the drive of the limit piece, a series drive effect is formed, so that the remaining plugs also move accordingly, forming an equal interval distribution effect of the plugs. Compared with the prior art, this structure can distribute multiple plugs at one time, improve processing efficiency, and facilitate subsequent operations.

[0009] Wherein, a limit mechanism is further included, and the limit mechanism is located on the movement track of the plug cooperating with the first driving mechanism; or, the plug on the side away from the driving block is fixedly connected to the upper fixed cavity.

[0010] With the arrangement of the limit mechanism, a limit and fixation effect is formed, so that the plugs are limited after moving, ensuring that the adjacent two plugs are arranged at equal intervals and fixed in one area.

[0012] The cooperation between the driving member and the driving block better realizes the driving effect, and the driving block can be adjusted according to actual needs to meet different processing requirements.

[0029] Embodiment 1:

[0030] A variable pitch mechanism, as shown in the attached Figures 1-5 figure, includes:

[0031] A frame 11, the frame 11 is provided with an upper fixed cavity 111, the upper fixed cavity 111 is provided with a chute 112, and a plurality of limiting members 12 are accommodated in the chute 112. Here, the number of the limiting members 12 can be adjusted according to actual needs, and two adjacent limiting members 12 are arranged in a fitting manner.

[0032] A plurality of plugs 13, the number of the plugs 13 can be adjusted according to actual needs. The plugs 13 are accommodated in the upper fixed cavity 111. Here, the size of the plugs 13 located in the upper fixed cavity 111 can be adjusted according to usage requirements. In this embodiment, part of the plugs 13 are located inside the upper fixed cavity 111, and the remaining parts of the plugs 13 extend outside the upper fixed cavity 111. The plugs 13 are provided with a chamber 131 opening downward, that is, a reverse U-shaped structure is formed. One end of the limiting member 12 extends into the chamber 131 of one of the plugs 13, and the other end of the limiting member 12 extends into the chamber 131 of the adjacent plug 13. When one of the plugs 13 moves, the side wall of the limiting member 12 is on the movement track of the side wall of the chamber 131, and the side wall of the chamber 131 abuts against the side wall of the limiting member 12, realizing that the plug 13 drives the limiting member 12 to move. When moving a certain distance, the other side wall of the limiting member 12 abuts against the side wall of the chamber 131 of the adjacent plug 13, driving the adjacent plug 13 to move, that is, the limiting member 12 forms a linkage effect between two adjacent plugs 13. At this time, the distance between two adjacent plugs 13 is controlled by the limiting member 12. When the farthest limiting member 12 moves so that the outermost plug 13 fits against the side wall of the farthest limiting member 12, all the plugs 13 are equally spaced, that is, a train-type splicing connection is formed.

[0033] The first driving mechanism 14 includes a driving block 141. The driving block 141 extends into the chamber 131 of the outermost plug 13, and the first driving mechanism 14 drives the outermost plug 13 to move. Here, the first driving mechanism 14 further includes a first driving source 142, and the first driving source 142 drives the driving block 141 to move. Through the movement of the driving block 141, the movement effect between adjacent plugs 13 is achieved. With this structural arrangement, during use, after the plug 13 is fixed in the upper fixed chamber 111, the first driving mechanism 14 operates, and the driving block 141 drives the outermost plug 13 to move. Driven by the limiting member 12, a series driving effect is formed, causing the remaining plugs 13 to also move accordingly, resulting in an equidistant distribution effect of the plugs 13. Compared with the prior art, this structure can distribute multiple plugs 13 at one time, improving the processing efficiency and facilitating subsequent operations.

[0034] Specifically, as shown in the appendix Figure 4 It also includes a limiting mechanism. The limiting mechanism is located on the movement trajectory of the plug 13 that cooperates with the first driving mechanism 14. For example, when the first driving mechanism 14 drives the plug 13 to move towards the left, the limiting mechanism is located on the leftmost movement trajectory to form a limiting effect. When the leftmost plug 13 abuts against the limiting mechanism, it stops working. Or, the plug 13 on the side away from the driving block 141 is connected and fixed to the upper fixed chamber 111. For example, the leftmost plug 13 cooperates with the driving block 141, and the rightmost plug 13 is connected and fixed to the upper fixed chamber 111. Here, the connection and fixing method can be bolt fixing (the bolt passes through the rightmost plug 13 and is connected and fixed to the upper fixed chamber 111), or pin fixing, or snap fixing, etc. When the rightmost limiting member 12 cooperates with the rightmost plug 13, it stops working. With the setting of the limiting mechanism, a limiting and fixing effect is formed, enabling the plug 13 to be limited after moving, ensuring an equidistant setting between adjacent two plugs 13 and being fixed in a specific area. In addition, it can also be achieved without a limiting mechanism. When all the plugs 13 move, an equidistant distribution effect can also be achieved. The only drawback is that the movement stroke is too long.

[0035] Specifically, as shown in the appendix Figures 1-4 The first driving mechanism 14 further includes a driving member 143. The driving member 143 is provided with a through hole 1431, and the driving block 141 is inserted into the through hole 1431. The cooperation between the driving member 143 and the driving block 141 better realizes the driving effect, and the driving block 141 can be adjusted according to actual needs to meet different processing requirements. Here, the driving member 143 is of a cuboid structure, and the driving member 143 is connected to the first driving source 142. Here, the first driving source 142 can be a cylinder, or an oil cylinder, or a motor, etc.

[0036] Specifically, as shown in the appendixFigures 1-4 As shown, it further includes a first slider mechanism 15. The first slider mechanism 15 includes a first slider 151 and a first slide rail 152. The first slider 151 slides on the first slide rail 152, and the first slider 151 is connected to the driving member 143. The setting of the first slider mechanism 15 makes the driving member 143 slide more stably. In addition, other sliding methods can also be used for cooperation. Here, the number of the first sliders 151 can be one, two, or more.

[0037] Specifically, the number of the sliding grooves 112 is one, two, or more than two. Each sliding groove 112 accommodates a limiting member 12. The setting of multiple sliding grooves 112 forms a cooperation effect, making the transmission effect between two adjacent plugs 13 more stable and preventing shaking or deviation. In this embodiment, the number of the sliding grooves 112 is two, and the setting of the two sliding grooves 112 makes the movement of the plug 13 more stable.

[0038] Specifically, as shown in the appendix Figures 1-4 As shown, the limiting member 12 is of a U-shaped structure. The U-shaped horizontal length of the limiting member 12 can control the distance between two adjacent plugs 13. When the distance needs to be adjusted, it can be achieved by replacing the limiting member 12. It should be noted that before assembling the plug 13, the position of the limiting member 12 needs to be adjusted to prevent the side wall of the plug 13 from abutting against the side wall of the limiting member 12.

[0039] Specifically, as shown in the appendix Figures 1-4 As shown, it further includes a pressing mechanism 16. The frame 11 includes a pressing plate 17, a cover plate 18, and a pushing plate 19. The pressing plate 17 is located between the cover plate 18 and the pushing plate 19. The pressing plate 17 and the cover plate 18 form an upper fixing cavity 111. The pressing plate 17 and the cover plate 18 are arranged parallel to each other up and down. A first support block 171 is fixed on the pressing plate 17, and the cover plate 18 is connected to the pressing plate 17 through the first support block 171. In this embodiment, the length of the pressing plate 17 is greater than the length of the cover plate 18. It should be noted that the sliding groove 112 is arranged on the pressing plate 17. The pressing plate 17 and the pushing plate 19 form a lower fixing cavity 113. The pressing plate 17 and the pushing plate 19 are also arranged parallel to each other up and down. A second support block 191 is fixed on the pushing plate 19, and the top surface of the pressing plate 17 abuts against the second support block 191. The pressing mechanism 16 presses and fixes the pressing plate 17. Through the pressing mechanism 16, the fixing effect of the pressing plate 17 is formed. When disassembly is required, disassembly, replacement, and maintenance can be quickly achieved by releasing the pressing mechanism 16. In this embodiment, the number of the pressing mechanisms 16 is two, and the two pressing mechanisms 16 are symmetrically arranged and are respectively arranged on both sides of the pressing plate 17. It should be noted that the first slider mechanism 15 is accommodated in the lower fixing cavity 113, and the driving member 143 is also accommodated in the lower fixing cavity 113.

[0040] Specifically, as shown in the appendix Figures 1-4As shown in the figure, the pressing mechanism 16 includes a pressing block 161, a handle 162 and a multi-link locking structure 163. One end of the multi-link locking structure 163 is connected to the handle 162, and the other end of the multi-link locking structure 163 is connected to the pressing block 161. The pressing block 161 abuts against the pressing plate 17. The cooperation between the handle 162 and the multi-link locking structure 163 can easily achieve the pressing effect of the pressing plate 17 after rotation, and can also easily solve the pressing of the pressing plate 17 and enable quick disassembly. Since the multi-link locking structure 163 is a prior art, it will not be described in detail in this embodiment.

[0041] Specifically, it further includes a second slider mechanism 20 and a frame 21. The second slider mechanism 20 is located on the frame 21. The second slider mechanism 20 includes a second driving source 201, a second slider and a second slide rail 203. The second driving source 201 is connected to the second slider to form the driving effect of the second slider. The second slider slides on the second slide rail 203, and the second slider is fixedly connected to the push plate 19. The setting of the second slider mechanism 20 forms the movement effect of the entire frame 11, which can cooperate with other devices to form the supply and conveying effect of the plug 13, facilitating subsequent processing operations. In this embodiment, the frame 21 is fixed, the frame 11 can move back and forth, and the plug 13 is inserted into the upper fixed cavity 111 from the front end, and then the plug 13 is driven by the first driving source 142 to move horizontally to the left, thus achieving the effect of equidistant distribution.
