Description

Technical Field

[0001] This invention relates to the field of steel cage production equipment technology, and more specifically, to a sleeve alignment device. Background Technology

[0002] In industrial production, many similar bar-shaped components require sleeves. For example, the reinforcing bars in the steel reinforcement cage of high-speed railway track slabs need to be fitted with multiple sleeves spaced at specific intervals. These sleeves are then heat-shrinked to fix them in their predetermined positions on the reinforcing bars. Specifically, for example... Figure 1 As shown, the main reason for using sleeves on the transverse and vertical reinforcement bars of the high-speed railway track slab reinforcement cage is that the longitudinal and planar closed loops of the reinforcement bars in the ballastless track slab will generate a magnetic field, which will affect the transmission performance of the resonant uninsulated track circuit. Therefore, it is necessary to insulate the track slab reinforcement cage to eliminate the closed loops formed by the reinforcement bars inside the track slab. In actual production, insulation of the reinforcement cage is achieved by sleeves on the reinforcement bars in several sections. However, in the existing technology, many sections of sleeves are usually sleeved on the reinforcement bars one by one by manual or mechanical means. During the reinforcement transport process, the position of the sleeves is prone to change before heat shrinkage, and the position of the sleeves will deviate after heat shrinkage, resulting in unqualified reinforcement cage quality. Summary of the Invention

[0003] To address the issue of the sleeve shifting position before heat shrinkage after being inserted into the reinforcing bar, this invention discloses a sleeve alignment device that can adjust the position of the sleeve to return it to a set position.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A sleeve alignment device includes a support frame, on which a vertical drive mechanism is mounted, the vertical drive mechanism driving a horizontal drive mechanism, and at least one clamping mechanism is mounted on the output end of the horizontal drive mechanism; or, the vertical drive mechanism is movably disposed on the support frame, and at least one clamping mechanism is mounted on the output end of the vertical drive mechanism; the radius of the clamping opening of the clamping mechanism is larger than the radius of the reinforcing bar and smaller than the radius of the sleeve.

[0006] As a further technical solution, the vertical drive mechanism is fixedly installed on the support frame; the horizontal drive mechanism includes a first horizontal drive mechanism and a second horizontal drive mechanism, the first horizontal drive mechanism drives a first slide, the second horizontal drive mechanism is installed at the bottom of the first slide, the second horizontal drive mechanism drives a second slide, and the driving directions of the first horizontal drive mechanism and the second horizontal drive mechanism are opposite; the clamping mechanism is installed at the bottom of the second slide.

[0007] As a further technical solution, the clamping mechanism includes a pneumatic finger, which drives the first and second paddles to close or open.

[0008] As a further technical solution, both the first and second paddles are provided with semi-circular notches, and the first and second paddles close to form the clamping opening.

[0009] As a further technical solution, the first and second paddles are mounted on the paddle mounting strip, and the pneumatic finger drives the paddle mounting strip to move.

[0010] As a further technical solution, multiple sets of opposing first and second paddles are installed on the paddle mounting strip.

[0011] As a further technical solution, a rebar conveying device is also included, which is located below the clamping mechanism.

[0012] As a further technical solution, the steel bar conveying device includes two conveying chains, and each conveying chain is provided with a positioning groove for positioning the steel bar.

[0013] As a further technical solution, a top steel bar mechanism is also installed on both sides of the support frame. The top steel bar mechanism includes a top tightening drive device and a top steel bar push plate connected to the power output end of the top tightening drive device.

[0014] As a further technical solution, the top steel bar mechanism located on different sides of the support frame is symmetrically arranged to tighten the two ends of the same or multiple steel bars.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This device can align and position the sleeve, ensuring accurate positioning of the heat-shrinked sleeve and improving production quality. Furthermore, two horizontal drive mechanisms are set in this device. After the clamping mechanism is closed, the two horizontal drive mechanisms can drive left and right to complete the bidirectional alignment of the sleeve and improve the alignment efficiency.

Therefore, they should not be construed as limitations on this invention.

[0033] As described in the background section, the present invention addresses the shortcomings of existing technologies and proposes a sleeve alignment device for adjusting the position of sleeve 2 on rebar 1. Specifically, the sleeve alignment device includes a support frame 3, with a vertical drive mechanism installed on the top of the support frame 3. The vertical drive mechanism drives a horizontal drive mechanism. Specifically, a horizontal drive mechanism can be installed at the power output end of the vertical drive mechanism, and at least one clamping mechanism can be installed at the output end of the horizontal drive mechanism. Alternatively, the vertical drive mechanism can be movably mounted on the support frame 3, and at least one clamping mechanism can be installed at the power output end of the vertical drive mechanism. The radius of the clamping opening of the clamping mechanism is larger than the radius of rebar 1 and smaller than the radius (outer diameter) of sleeve 2.

[0034] In a typical embodiment of the present invention, such as Figures 2-8 As shown, the vertical drive mechanism is fixedly installed on the top of the support frame 3. The horizontal drive mechanism preferably includes a first horizontal drive mechanism and a second horizontal drive mechanism. The first horizontal drive mechanism drives the first slide, and the second horizontal drive mechanism is installed at the bottom of the first slide, driving the second slide. The driving directions of the first and second horizontal drive mechanisms are opposite. A clamping mechanism is installed at the bottom of the second slide. With the arrangement of the first and second horizontal drive mechanisms, after the clamping mechanism is closed, the two horizontal drive mechanisms can drive left and right, thus completing the bidirectional alignment of the sleeve 2 and improving efficiency.

[0035] A conveying device 22 is provided below the clamping mechanism. The conveying device 22 may include multiple conveying chains for simultaneously conveying multiple steel bars 1, thereby achieving continuous operation of aligning the sleeves 2 on the steel bars 1. Preferably, each segment of the conveying chain is provided with a positioning block, and the positioning block has a positioning groove 23.

[0036] Specifically, the sleeve alignment device disclosed in this embodiment includes a support frame 3, a lifting cylinder 4, a first horizontal drive cylinder 5, a second horizontal drive cylinder 6, a pneumatic finger 7, a first paddle mounting strip 8, a second paddle mounting strip 9, a first paddle 10, a second paddle 11, a top rebar cylinder 12, a top rebar cylinder 13, a top rebar push plate 14, a top rebar push plate 15, a lifting cylinder mounting plate 16, an upper slide mounting plate 17, a lower slide mounting plate 18, a pneumatic finger mounting plate 19, an upper slide 20, and a lower slide 21.

[0037] In this embodiment, the vertical drive mechanism uses a lifting cylinder 4, the first horizontal drive mechanism uses a first horizontal drive cylinder 5, and the second horizontal drive mechanism uses a second horizontal drive cylinder 6; the first slide uses an upper slide 20, the second slide uses a lower slide 21, and the clamping mechanism uses a pneumatic finger 7; the connection relationship of each component is as follows:

[0038] The lifting cylinder 4 is fixedly mounted on the lifting cylinder mounting plate 16, which is entirely fixed to the support frame 3, so that the lifting cylinder 4 is suspended on the support frame 3, and the lifting cylinder 4 provides the drive for vertical movement; the first horizontal drive cylinder 5 is connected to the power output end of the lifting cylinder 4 through the upper slide plate 17, that is, the lifting cylinder 4 can drive the first horizontal drive cylinder 5 to move up and down; and the first horizontal drive cylinder 5 drives an upper slide 20 to move horizontally to the left. The upper slide 20 is slidably mounted on the lower end of the first horizontal drive cylinder 5. The first horizontal drive cylinder 5 and the upper slide 20 can slide together through a guide rail slider. For example, a guide rail is set at the lower end of the first horizontal drive cylinder 5, and a slider is set at the upper end of the upper slide 20 to cooperate with the guide rail. A connecting block is set at one end of the upper slide 20 and is fixedly connected to the telescopic rod of the first horizontal drive cylinder 5, that is, the first horizontal drive cylinder 5 provides a horizontal driving force; the second water The horizontal drive cylinder 6 is mounted on the bottom of the upper slide table 20 via the lower slide table mounting plate 18. The second horizontal drive cylinder 6 drives the lower slide table 21 to move to the right. The lower slide table 21 is slidably mounted on the lower end of the second horizontal drive cylinder 6. The second horizontal drive cylinder 6 and the lower slide table 21 can slide together via a guide rail slider. For example, a guide rail is set at the lower end of the second horizontal drive cylinder 6, and a slider is set at the upper end of the lower slide table 21 to cooperate with the guide rail. A connecting block is set at one end of the lower slide table 21 and is fixedly connected to the telescopic rod of the second horizontal drive cylinder 6. That is, the second horizontal drive cylinder 6 also provides a horizontal driving force. The two horizontal drive mechanisms are arranged in opposite directions, one to the left and one to the right. After the clamping mechanism is closed, the first horizontal drive cylinder 5 and the second horizontal drive cylinder 6 drive the clamping mechanism to the left and right directions respectively. The clamping mechanism pushes the sleeve 2 from the left and right sides, moving the sleeve 2 to the preset position, completing the bidirectional alignment of the sleeve 2, and improving efficiency. At the same time, the above-mentioned horizontal drive mechanism ensures the smoothness of the left and right movement of the clamping mechanism, improves the alignment accuracy, and the equipment structure is compact.

[0039] Furthermore, the clamping mechanism includes pneumatic fingers 7, which drive the first lever 10 and the second lever 11 to close or open. In this embodiment, a pneumatic finger mounting plate 19 is installed at the bottom of the sliding platform 21. The extension direction of the pneumatic finger mounting plate 19 is perpendicular to the horizontal driving direction. Two sets of pneumatic fingers 7 are installed side by side at the bottom of the pneumatic finger mounting plate 19. One set of pneumatic fingers 7 drives one set of lever mounting strips, and the other set of pneumatic fingers 7 drives another set of lever mounting strips. That is, the two power output ends of the pneumatic fingers 7 are respectively connected to the first lever mounting strip 8 and the second lever mounting strip 9. Of course, it is easy to understand that in other embodiments, one or more sets of pneumatic fingers 7 can be set. The multiple sets of pneumatic fingers 7 are spaced apart along the direction perpendicular to the horizontal driving direction. After the levers are closed, the distance between the clamping openings of two adjacent sets of clamping mechanisms is a multiple of the distance between adjacent positioning grooves 23 of the conveyor chain, which can continuously and simultaneously align the sleeves 2 on multiple steel bars 1, achieving high efficiency, precision, and continuous alignment.

[0040] The following explanation uses one of these groups as an example.

[0041] Each set of paddle mounting strips includes two paddle mounting strips, namely the first paddle mounting strip 8 and the second paddle mounting strip 9 in this embodiment. A first paddle 10 is set on the first paddle mounting strip 8, and a second paddle 11 is set on the second paddle mounting strip 9. The first paddle 10 and the second paddle 11 are paired to form a paddle assembly. Both paddles have a semi-circular notch. The radius of the notch is larger than the radius of the reinforcing bar 1 and smaller than the radius of the sleeve 2 before heat shrinking, so that the two paddles can push the sleeve 2 to move relative to the reinforcing bar 1, thereby adjusting the position of the sleeve 2. Furthermore, the surfaces of the first paddle 10 and the second paddle 11 are coplanar when installed, ensuring that the notches on the first paddle 10 and the second paddle 11 can be aligned after the pneumatic finger 7 is closed.

[0042] Furthermore, each set of lever mounting strips can be equipped with multiple sets of corresponding first levers 10 and second levers 11. The specific number of sets is determined according to the number of sleeves 2 on the rebar 1. Generally, one sleeve 2 corresponds to one or two sets of first levers 10 and second levers 11. Multiple sets of levers are combined and installed side by side on the lever mounting strip, which can simultaneously complete the alignment of multiple sleeves 2. The sleeves 2 located at both ends of the rebar 1 can correspond to one set of first levers 10 and second levers 11, and the sleeves 2 located in the middle preferably correspond to two sets of first levers 10 and second levers 11. These two sets of first levers 10 and second levers 11 are located on the left and right sides of the sleeve 2, respectively. The clamping mechanism moves left and right to achieve bidirectional alignment of the sleeves 2.

[0043] Furthermore, a top rebar mechanism is installed on the left and / or right frames of the support frame 3. The top rebar mechanism on the left frame includes a tightening drive device and a top rebar push plate 14. The power output end of the tightening drive device is connected to the top rebar push plate 14. The tightening drive device can be a top rebar cylinder 12. And / or, the top rebar mechanism on the right frame includes a tightening drive device and a top rebar push plate 15. The power output end of the tightening drive device is connected to the top rebar push plate 15. The tightening drive device can be a top rebar cylinder 13. Preferably, both the left and right frames of the support frame 3 are equipped with top rebar mechanisms, and the left and right top rebar mechanisms are symmetrically arranged to align the two ends of the rebar 1.

[0044] It should be noted that, since the lifting cylinder 4 is connected to the first horizontal drive cylinder 5, the first horizontal drive cylinder 5 is connected to the second horizontal drive cylinder 6, and the second horizontal drive cylinder 6 is connected to the pneumatic finger 7, when the lifting cylinder 4 moves up and down, the first horizontal drive cylinder 5, the second horizontal drive cylinder 6, and the pneumatic finger 7 can move up and down synchronously.

[0045] Furthermore, the specific working process of the sleeve alignment device in this embodiment is as follows:

[0046] When the sleeve alignment device is in its initial state, the lifting cylinder 4 is in the raised state, the first horizontal drive cylinder 5 and the second horizontal drive cylinder 6 are in the retracted state, and the pneumatic finger 7 is in the open state. When the steel bar 1 with the sleeve 2 fitted at the bottom of the device moves through the conveying device 22 to the position directly below the middle of the two rows of first deflectors 10 and second deflectors 11, the two steel bar lifting mechanisms are activated. The steel bar 1 is pressed and aligned by the steel bar lifting plate 14 and the steel bar lifting plate 15. Then, the lifting cylinder 4 extends, the center of the deflector notch descends to the same height as the axis of the steel bar 1, the pneumatic finger 7 closes, the first horizontal drive cylinder 5 extends, and the pneumatic finger 7 pushes the sleeve 2 from one side to align it in one direction. The first horizontal drive cylinder 5 retracts, the second horizontal drive cylinder 6 extends, and the pneumatic finger 7 aligns the sleeve 2 from the other side to the other direction, achieving bidirectional alignment of the sleeve 2. Finally, the second horizontal drive cylinder 6 retracts, the pneumatic finger 7 opens, the lifting cylinder 4 retracts, the pressing drive device 12 and the steel bar lifting cylinder 13 retract, and the steel bar 1 continues to be conveyed forward to continue aligning the sleeve 2 on the next steel bar 1.

[0047] Furthermore, it should be noted that the aforementioned vertical drive mechanism can also be movably mounted on the support frame 3, for example, via a guide rail slider assembly. A drive motor or similar device drives the vertical drive mechanism to move left and right. The power output end of the vertical drive mechanism is connected to the clamping mechanism. The left and right movement of the vertical drive mechanism drives the clamping mechanism to move horizontally, thereby aligning the sleeve 2. Preferably, the vertical drive mechanism is fixedly mounted on the support frame 3 to improve stability and alignment accuracy.

[0048] It should be further noted that the lifting cylinder 4 mentioned above is only one specific method of vertical drive mechanism, and can also be replaced by other motor-driven lifting devices, hydraulic cylinder-driven lifting devices, etc., with cylinder being the preferred choice.

[0049] It should be further noted that the first horizontal drive cylinder 5 and the second horizontal drive cylinder 6 are specific forms of the horizontal drive mechanism, and can also be replaced by devices such as hydraulic cylinders.

[0050] It should be further noted that the pneumatic finger 7 is a specific form of the gripping drive mechanism, and can also be replaced by a device such as a robotic arm or a cylinder.

[0051] It should be further explained that the top steel bar cylinder 12 and the top steel bar cylinder 13 are specific forms of the top clamping drive device, and can also be replaced by a motor or a hydraulic cylinder.

[0052] It should be understood that the rectangular frame has a top-bottom structure, which serves as the top-bottom orientation reference system in this invention.

[0053] Finally, it should be noted that relational terms such as first and second are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
