Description

Technical Field

[0001] The present application relates to the technical field of bar processing, and in particular to a bin cover locking mechanism and a bar feeder. Background Art

[0002] CNC lathes are currently widely used in the processing of parts and components such as pipes, rods, internal and external threads, and cones. For ordinary CNC lathes, each workpiece needs to be manually taken out and the material is placed in the chuck for clamping and tool alignment after processing. This operation method has certain deficiencies in safety and efficiency. A bar feeder control system has been developed in the prior art. The bar feeder control system can automatically feed the CNC lathe, effectively reducing labor costs and improving production efficiency.

[0003] In the field of bar feeder machinery, the technical development of the bin cover locking structure has always been the focus of the industry. The traditional bin cover locking method mainly relies on the spring tensioning mechanism, and the bin cover is tightly closed through the elastic deformation of the spring. This technology has provided the basic locking function for the bar feeder for a period of time, ensuring the smooth progress of the feeding process.

[0004] However, with the continuous advancement of industrial technology and the increase in application needs, the traditional spring-tensioned bin cover locking structure has gradually exposed its limitations. During long-term use, the spring is prone to lose its elasticity due to fatigue, resulting in a decrease in locking force; at the same time, the spring tensioning method requires a high level of operator proficiency, and improper operation may cause the bin cover to be loosely locked or difficult to open. Therefore, the traditional spring-tensioned bin cover locking structure can no longer meet the needs of modern bar feeders for high efficiency, high stability and high safety. Utility Model Content

[0005] In response to the above problems, the present application provides a bin cover locking mechanism to overcome the defects of traditional technology, facilitate the locking of the bin cover, and improve the overall performance of the bar feeder.

[0006] In the first aspect, the present application provides a compartment cover locking mechanism that adopts the following technical solution:

[0007] A bin cover locking mechanism comprises a track, a bin cover, a driving member, a pressing member and a limiting member, wherein the bin cover is used to cover the track, the driving member is connected to the bin cover, the pressing member is connected to the driving member, the driving member is used to control the reciprocating movement of the pressing member, the limiting member is arranged above the pressing member and on the moving path of the pressing member, and the pressing member is used to press against the limiting member.

[0008] By adopting the above technical solution, when the bin cover needs to be locked, the bin cover is placed on the track. At this time, the driving member is started, and the driving member drives the pressing member to gradually approach the limiting member and press against the lower side of the limiting member, thereby generating a clamping force to stably press the bin cover on the track.

[0009] This structure uses the cooperation of the pressing piece and the limit piece to achieve stable compression of the bin cover on the track, solving the problems existing in the traditional spring tension bin cover locking structure. Compared with the existing technology, the optimized technical solution has the advantages of firm locking, simple operation, strong durability, etc., while providing a more convenient operating experience and higher safety performance; it can be widely used in the field of bar feeding machinery, especially those occasions with high requirements for bin cover locking performance, such as high-speed and high-precision bar feeding operations.

[0010] Preferably, the driving member is a driving cylinder or an electric push rod, and the pressing member is connected to the piston rod of the driving cylinder or the electric push rod.

[0011] By adopting the above technical solution, the reciprocating motion of the pressing member can be achieved by using a driving cylinder or an electric push rod.

[0012] Preferably, the pressing member is provided with an inclined guiding portion and a contact portion, respectively. The contact portion is located at a higher end of two ends of the inclined guiding portion, and the contact portion is used for tightly contacting with the limiting member.

[0013] By adopting the above technical solution, when the driving member gradually drives the pressing member to approach the limiting member, the vertical distance between the limiting member and the inclined guide portion will gradually decrease. As the pressing member continues to approach, the inclined guide portion will play a guiding role so that the contact portion can better transition and press against the lower side of the limiting member.

[0014] Preferably, the side of the limiting member in contact with the contact portion is elliptical in shape.

[0015] By adopting the above technical solution, the elliptical lower side of the limiting member can reduce the contact area with the contact portion, thereby facilitating the contact portion to be clamped on the limiting member.

[0016] Preferably, it further comprises a mounting plate, an adjustment plate and a fastener, wherein the limit member is arranged on the adjustment plate, and the adjustment plate is locked to the mounting plate by the fastener.

[0017] By adopting the above technical solution, the adjustment plate is locked on the mounting plate by fasteners, and the position of the adjustment plate relative to the mounting plate can be adjusted according to actual needs, thereby changing the distance between the limiter and the bin cover, thereby achieving adjustable locking force and improving applicability.

[0018] Preferably, the bin cover is also provided with a bar pressing assembly, and the bar pressing assembly is used to press the bars.

[0019] By adopting the above technical solution, after the bin cover is tightly closed on the track, the bar pressing assembly is used to press the bar to achieve self-locking, thereby achieving the effect of preventing the bar from vibrating.

[0020] Preferably, the bar pressing assembly comprises a pneumatic cylinder and an elastic pressing block, the pneumatic cylinder is connected to the bin cover, the elastic pressing block is connected to the piston rod of the pneumatic cylinder, and the elastic pressing block faces the track and is used to press the bar.

[0021] By adopting the above technical solution, after the bin cover is closed, the piston rod of the pneumatic cylinder is pushed out, thereby controlling the elastic pressing block to press the rod.

[0022] In the second aspect, the present application also provides a bar feeder, which adopts the following technical solution:

[0023] A bar feeder comprises a bin cover locking mechanism with all the above structures.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] (1) By setting a driving member, a pressing member and a limiting member, the driving member is installed on the bin cover, and the piston rod of the driving member is oriented toward the track. When the bin cover needs to be locked, the bin cover is placed on the track, and the driving member is started at this time, and the piston rod of the driving member is pushed out. As the piston rod is pushed out, the pressing member presses against the lower side of the limiting member, thereby generating a clamping force to stably press the bin cover on the track. Compared with the prior art, this technology mainly solves the technical problems of the bin cover of the bar feeder being loosely locked, inconvenient to operate, and poor durability.

[0026] (2) By setting the adjustment plate and the fastener, the position of the adjustment plate relative to the mounting plate can be adjusted according to actual needs, and the distance between the limiter and the compartment cover can be changed to achieve the adjustment of the locking force.

[0027] (3) By setting a rod clamping assembly, the rod clamping assembly can clamp the rod and achieve self-locking, thereby preventing the rod from vibrating. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, those skilled in the art may combine and combine different embodiments or examples and features of different embodiments or examples shown in the present application.

[0037] Example 1

[0038] The present application embodiment discloses a compartment cover locking mechanism. Figure 1 and Figure 2The bin cover locking mechanism includes a frame 1, a track 2, a bin cover 3, a driving member 4, a pressing member 5 and a limiting member 6. The frame 1 serves as a supporting carrier, and the track 2 is fixedly mounted on the frame 1. A corresponding arc groove is provided on the track 2, and the shape of the arc groove is adapted to the shape of the rod, so that the rod can be accommodated and fit in the arc groove. The bin cover 3 is located above the notch of the track 2 and is used to cover the track 2 to press the rod on the track 2. The driving member 4 is fixedly connected to the bin cover 3. The driving member 4 is a driving cylinder or an electric push rod. In this embodiment, the driving cylinder is used for explanation. The pressing member 5 is block-shaped and fixedly connected to the piston rod of the driving cylinder. The driving cylinder is used to control the pressing member 5 to perform linear reciprocating motion. The limiter 6 is located above the pressing member 5 and on the moving path of the pressing member 5; when the driving cylinder controls the pressing member 5 to gradually approach the limiter 6, the pressing member 5 will gradually contact the limiter 6 and press against the limiter 6. The driving cylinder uses a high-performance cylinder to ensure that the piston rod has sufficient ejection force and stability. At the same time, the driving cylinder is supplemented with a control system to achieve precise control and automatic operation of the driving cylinder.

[0039] When it is necessary to lock the bin cover 3, the bin cover 3 is placed on the track 2. At this time, the driving cylinder is started, and the driving cylinder drives the pressing member 5 to gradually approach the limiting member 6 and press against the lower side of the limiting member 6, thereby generating a pressing force to stably press the bin cover 3 on the track 2.

[0040] This structure utilizes the cooperation of the pressing member 5 and the limiting member 6 to realize the stable compression of the bin cover 3 on the track 2, and solves the problems existing in the locking structure of the traditional spring tensioning bin cover 3. Compared with the prior art, the optimized technical solution has the advantages of firm locking, simple operation, strong durability, etc., while providing a more convenient operation experience and higher safety performance; it can be widely used in the field of bar feeding machinery, especially in those occasions with high requirements for the locking performance of the bin cover 3, such as high-speed and high-precision bar feeding operations.

[0041] Specifically, the upper end of the pressing member 5 is provided with an inclined guide portion 7 and a contact portion 8, respectively. The inclined guide portion 7 is in the shape of an oblique line, and the contact portion 8 is located at a relatively higher end of the two ends of the inclined guide portion 7. The contact portion 8 is in the shape of a horizontal straight line and is used to be in close contact with the limiting member 6. When the driving member 4 gradually drives the pressing member 5 to approach the limiting member 6, the vertical distance between the limiting member 6 and the inclined guide portion 7 will gradually decrease. As the pressing member 5 continues to approach, the inclined guide portion 7 will play a guiding role, so that the contact portion 8 can better transition and be in close contact with the lower side of the limiting member 6.

[0042] The stopper 6 is cylindrical, so that the side where the stopper 6 contacts the contact part 8 is in an arc shape. The arc-shaped stopper 6 can reduce the contact area with the contact part 8, so that the contact part 8 is conveniently clamped on the stopper 6; and the circle is a special ellipse, and the stopper 6 can also be a flat ellipse, not limited to a circle. The structure of the stopper 6 is optimized and designed to improve the matching accuracy and wear resistance of the stopper 6 with the pressing part 5. At the same time, the stopper 6 is made of high-strength and wear-resistant materials to improve its service life and reliability.

[0043] In addition, the frame 1 is also respectively mounted with a mounting plate 9, an adjustment plate 10 and a fastener 11, the mounting plate 9 is welded to the frame 1, the limiter 6 is fixedly connected to the adjustment plate 10, and the adjustment plate 10 is locked to the mounting plate 9 by the fastener 11, and the fastener 11 is a fastening bolt or a fastening screw to realize the detachability of the adjustment plate 10. At this time, the position of the adjustment plate 10 relative to the mounting plate 9 can be adjusted according to actual needs, thereby changing the distance of the limiter 6 relative to the bin cover 3, realizing the adjustable locking force and improving applicability.

[0044] According to some embodiments of the present application, optionally, please refer to Figure 3 . A bar pressing assembly 12 is also installed on the bin cover 3, and the bar pressing assembly 12 is used to press the bars on the track 2. Specifically, the bar pressing assembly 12 includes a pneumatic cylinder 121 and an elastic pressing block 122. The pneumatic cylinder 121 is fixedly connected to the bin cover 3, and the elastic pressing block 122 is connected to the piston rod of the pneumatic cylinder 121; the elastic pressing block 122 is made of elastic materials such as rubber, and the elastic pressing block 122 faces the track 2 and is used to press the bars. After the bin cover 3 is tightly closed on the track 2, the piston rod of the pneumatic cylinder 121 is controlled to be ejected, thereby controlling the elastic pressing block 122 to press the bars, thereby preventing the bars from vibrating.

[0045] The implementation principle of a bin cover locking mechanism in the embodiment of the present application is as follows: a driving member 4 is installed on the bin cover 3, and the piston rod of the driving member 4 is oriented toward the track 2. When the bin cover 3 needs to be locked, the bin cover 3 is placed on the track 2, and the driving member 4 is started at this time, and the piston rod of the driving member 4 is pushed out. As the piston rod is pushed out, the pressing member 5 is pressed against the lower side of the limiting member 6, thereby generating a pressing force to stably press the bin cover 3 on the track 2.
