Description

Technical Field

[0001] The present application relates to the technical field of bolt thread rolling processing equipment, and in particular to a gasket vibration device with an automatic direction splitting function. Background Art

[0002] The vibration device includes a vibration plate, which is an automatic feeding device, usually composed of a hopper, a controller and other parts. The pulse signal generated by the controller is used to make the electromagnet generate an alternating magnetic field, which in turn drives the hopper to vibrate at a high frequency and a slight amplitude. A spiral track is installed in the hopper. Under the action of vibration, the parts in the hopper will move upward along the spiral track.

[0003] Putting a gasket on the bolt can enhance the sealing of the connection. One side of the convex-concave gasket is convex and the other side is concave. Due to its special shape, it can generate a certain radial pressure when the bolt is tightened, making the fit between the convex-concave gasket and the surface of the connected part closer. When putting the convex-concave gasket on the bolt, in order to ensure the sealing effect, the concave surface needs to face the connected part and the convex surface needs to contact the bolt head.

[0004] Conventional vibration plates only have the function of feeding gaskets. Before the gasket sleeve is placed on the bolt, all the convex surfaces of the gasket need to face upward and be consistently sent to the work station where the bolt is located. In the prior art, it is necessary to manually divide the gasket into sections and manually adjust them before placing the gasket sleeve on the bolt for subsequent thread rolling work, which reduces efficiency and affects production progress.

[0005] Therefore, a gasket vibrating device with an automatic direction-dividing function is needed to realize the problem of automatically dividing the convex and concave gaskets and then putting them on the bolts. Summary of the invention

[0006] The purpose of the present application is to provide a double-sided toothed gasket vibration device with an automatic direction separation function, which integrates the functions of feeding convex and concave gaskets, automatically dividing the surfaces, and putting them on bolts.

[0007] The present application provides a gasket vibration device with an automatic direction splitting function, which adopts the following technical solution: A gasket vibration device with an automatic direction separation function includes a device body, on which a first vibration plate and a spiral track located inside the first vibration plate are installed. The spiral track includes a removal section for removing gaskets whose convex surfaces are in contact with the spiral track, and a straightening section for straightening gaskets remaining on the spiral track after removal. The device body also includes a feeding mechanism for bolt feeding, the feeding mechanism includes a turntable component for conveying bolts, and a first discharging track for conveying gaskets is provided between the turntable component and the straightening section. After the turntable component drives the bolts to move, they come into contact with the gasket at the discharging end of the first discharging track so that the gasket sleeve is placed on the rod of the bolt.

[0008] By adopting the above technical scheme, the rejection section can effectively remove the rejection section whose convex surface is in contact with the spiral track, ensuring that the gaskets remaining in the spiral track are all concave surfaces that are in contact with the spiral track. The straightening section can adjust the position of qualified gaskets. The first discharging track and the turntable component cooperate with each other, so that the gasket can be accurately placed on the bolt rod during the movement of the bolt, thereby improving production efficiency and reducing the need for manual operation.

[0009] Optionally, the end surface of the removal section is protrudingly formed with a step convex strip having a width smaller than the thickness of the gasket, and the step convex strip is in conflict with the outer peripheral side of the gasket whose concave surface is attached to the spiral track.

[0010] By adopting the above technical solution, the width of the step ridge is set smaller than the thickness of the gasket, and the outer peripheral side of the gasket whose convex surface is attached to the spiral track exceeds the step ridge and slides down, so that the step ridge can effectively screen out the gasket with the convex surface facing outward and retain the gasket with the concave surface attached to the spiral track.

[0011] Optionally, an elastic abutment sheet is fixedly mounted on the discharge end of the straightening section, and the elastic abutment sheet cooperates with the side surface of the track of the straightening section to form a limiting channel for limiting the passage of individual gaskets in a queue.

[0012] By adopting the above technical solution, the limiting channel formed by the elastic resistance piece and the track side of the straightening section can effectively control the arrangement state of the gaskets, avoid the stacking of gaskets, ensure that the gaskets enter the subsequent process one by one in an orderly manner after passing through the straightening section, and improve the reliability of the gasket sleeve on the bolt.

[0013] Optionally, the first discharging track is inclined, and a height limiting plate is provided on the first discharging track, the height of the plate being higher than that of the gasket to prevent the gasket from escaping from the first discharging track.

[0014] By adopting the above technical solution, the first discharging track is inclined, so that the gasket moves downward in an orderly manner under the action of gravity, thereby improving the transmission efficiency of the gasket. The height limit plate effectively prevents the gasket from leaving the track due to vibration during the downward movement of the first discharging track, thereby ensuring that the gasket is stably transported to the designated position and improving the working reliability of the entire device.

[0015] Optionally, the turntable component includes a rotating disk rotatably mounted on the device body, and a plurality of placement grooves for placing bolts and through which only the rods of the bolts are passed are evenly distributed on the outer circumference of the rotating disk, and the surface of the rotating disk is in contact with the heads of the bolts. A protective strip is also fixedly mounted on the device body to prevent the bolts from detaching from the rotating disk, and the protective strip is arranged around the circumference of the rotating disk.

[0016] By adopting the above technical solution, the rod part of the bolt passes through the placement groove and is stably placed on the rotating disk, which can accurately define the position of the bolt on the rotating disk, enhance the stability of the bolt during the rotation of the rotating disk, and the protective strip is arranged around the circumference of the rotating disk, which can play a blocking role during the movement of the bolt with the rotating disk, preventing the bolt from separating from the rotating disk due to centrifugal force, thereby improving the reliability and safety of the operation of the entire device.

[0017] Optionally, the feeding mechanism further includes a support member that contacts the bottom of the gasket on the bolt and is used to support the gasket. An arc-shaped chute for the rod part of the bolt to extend into is provided on the support member. The arc-shaped chute extends along the moving direction of the bolt, and the vertical distance between the surface of the support member and the bottom surface of the rotating disk gradually decreases along the moving direction of the bolt.

[0018] By adopting the above technical solution, during the rotation of the rotating disk driving the bolt and the gasket sleeved on the bolt, the support member can effectively support the gasket sleeved on the rod part of the bolt. The design of the arc-shaped chute enables the rod part of the bolt to smoothly extend into the support member. As the bolt moves forward, the vertical distance between the support member and the bottom surface of the rotating disk gradually decreases, making the gasket gradually close to the head of the bolt, realizing the stable assembly of the gasket onto the bolt.

[0019] Optionally, a lever for separating the bolt from the rotating disk and a second discharge track for receiving the bolt after separation are fixedly connected to the device body.

[0020] By adopting the above technical solution, the setting of the lever enables the bolt to be stably separated from the rotating disk at an appropriate position, facilitating the bolt to enter the next process, improving the working efficiency and stability of the entire device. The setting of the second discharge track ensures that the bolt after separation can be smoothly transmitted to the subsequent process, realizing seamless connection in the automated production process and reducing the need for manual intervention.

[0021] Optionally, a discharge chute for the rod part of the bolt to penetrate into is provided on the second discharge track, and the top surface of the second discharge track abuts against the bottom surface of the gasket.

[0022] By adopting the above technical solution, the discharge chute provided on the second discharge track can accurately guide the direction of the bolt, ensuring the stability and accuracy of the bolt during the discharge process. The top surface of the second discharge track abuts against the bottom surface of the gasket. Under the influence of the gravity of the bolt, the distance between the gasket and the head of the bolt is further reduced and the gasket fits with the head of the bolt, ensuring the assembly effect of the gasket and the bolt.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. The rejection section can effectively reject the rejection section where the convex surface fits the spiral track, ensuring that the gaskets remaining in the spiral track all have the concave surface fitting the spiral track. The straightening section adjusts the positions of the qualified gaskets. The first discharge track and the turntable component cooperate with each other, so that during the movement of the bolt, the gasket is accurately sleeved on the rod part of the bolt, improving the production efficiency and reducing the need for manual operation. 2. The set width of the stepped convex strip is smaller than the thickness of the gasket. The gasket with the convex surface fitting on the spiral track slides off after the outer peripheral side exceeds the stepped convex strip, so that the stepped convex strip can effectively screen out the gaskets with the convex surface facing outward and retain the gaskets with the concave surface fitting on the spiral track. 3. The limiting channel formed by the elastic contact piece and the side surface of the track of the straightening section can effectively control the arrangement state of the gaskets, avoid the stacking phenomenon of the gaskets, ensure that the gaskets enter the subsequent processes one by one in an orderly manner after passing through the straightening section, and improve the reliability of sleeving the gaskets on the bolts.

Detailed Embodiment

[0026] The following further describes the present application in detail with reference to the attached Figures 1-4 drawings.

[0027] Embodiment: A gasket vibrating device with an automatic direction separation function, referring to Figure 1 and Figure 2The device body 1 is provided with a first vibration plate 2 and a spiral track 3, the spiral track 3 is fixedly installed in the first vibration plate 2, and the gasket is fed along the spiral track 3 through the vibration of the first vibration plate 2. Along the feeding direction of the gasket, the spiral track 3 is divided into a rejection section 4 and a straightening section 5, the track surface of the rejection section 4 faces the outside of the device body 1, and the track surface of the straightening section 5 faces the center of the device body 1. There is an arc transition between the rejection section 4 and the straightening section 5, and the rejection section 4 can reject the gasket whose convex surface is in contact with the spiral track 3, so as to ensure A gasket with a concave surface that fits the track is left, and the straightening section 5 straightens the retained gasket, with the convex surface of the gasket facing the first vibrating disk 2. The device body 1 is also equipped with a feeding mechanism 6, which realizes automatic feeding of bolts. The feeding mechanism 6 includes a turntable component 7, and a first discharging track 8 is provided between the turntable component 7 and the straightening section 5. The first discharging track 8 transports the gasket of the straightening section 5 to the turntable component 7. The turntable component 7 drives the bolt to move, so that the gasket sleeve at the discharging end of the first discharging track 8 is placed on the rod of the bolt.

[0028] refer to Figure 1 and Figure 2 The end face of the removal section 4 is protrudingly formed with a step ridge 9, which is extended along the moving direction of the gasket. The step ridge 9 is located at the bottom end of the removal section 4 and the setting width of the step ridge 9 is smaller than the thickness of the gasket. When the convex surface of the gasket is in contact with the end face of the removal section 4, the peripheral edge of the gasket is lower than the step ridge 9. Under the action of gravity of the gasket, the gasket whose convex surface is in contact with the end face of the removal section 4 slides off the spiral track 3, and the gasket whose concave surface is in contact with the end face of the removal section 4 has its peripheral edge in conflict with the step ridge 9, thereby preventing the gasket whose concave surface is in contact with the end face of the removal section 4 from sliding off the spiral track 3.

[0029] refer to Figure 1 and Figure 2 An elastic resistance piece 10 is installed at the discharge end of the straightening section 5. In the present embodiment, the elastic resistance piece 10 is made of iron and is a thin sheet. One end of the elastic resistance piece 10 is fixed on the device body 1, and the other end is extended and arranged on the side of the gasket. The elastic resistance piece 10 cooperates with the track side of the straightening section 5 to form a limiting channel 11. The setting width of the limiting channel 11 only allows a single gasket to pass through, so that the gaskets coming out of the straightening section 5 are lined up in sequence to enter the first discharge track 8, and the concave surface of the gasket entering the first discharge track 8 is away from the first vibration plate 2.

[0030] refer to Figure 3 and Figure 4 The setting height of the turntable component 7 is lower than the setting height of the straightening section 5, the first discharge track 8 is inclined, and a height limiting plate 23 located above the first discharge track 8 is fixedly installed on the device body 1. The distance between the height limiting plate 23 and the end face of the first discharge track 8 is greater than the upright height of the gasket, so as to prevent the gasket from leaving the first discharge track 8 when moving downward.

[0031] Reference Figure 3 and Figure 4 Figure 4 , the feeding mechanism 6 further includes a second vibrating disk 12 for automatically feeding bolts. The turntable component 7 further includes a rotating disk 13 which is rotatably mounted on the device body 1. A third discharge track 14 is connected between the rotating disk 13 and the second vibrating disk 12. The bolts fed from the second vibrating disk 12 enter the rotating disk 13 orderly through the third discharge track 14. The turntable component 7 further includes a rotating motor 15 for driving the rotating disk 13 to rotate. The output shaft of the rotating motor 15 is fixedly connected to the rotating disk 13. A placing groove 16 is formed on the rotating disk 13. The placing groove 16 is arranged on the outer peripheral side of the rotating disk 13 and the opening of the placing groove 16 faces outward. The bolts enter the rotating disk 13 from the third discharge track 14. The rod parts of the bolts pass through the placing groove 16, and the heads of the bolts abut against the surface of the rotating disk 13. A protective strip 17 is also installed on the device body 1. The protective strip 17 is arc-shaped and surrounds the rotating disk 13. The protective strip 17 abuts against the rod parts of the bolts to prevent the bolts from falling out of the placing groove 16. When the rotating disk 13 rotates to drive the bolts to move to the discharge end of the first discharge track 8, the rod parts of the bolts abut against the upright gaskets. The end faces of the rod parts of the bolts are opposite to the central holes of the gaskets. As the bolts move, the gaskets are overturned to the horizontal state, and the rod parts of the bolts extend into the central holes of the gaskets. The gaskets are successfully sleeved on the bolts, and the concave surfaces of the gaskets face the rod parts of the bolts.

[0032] Reference Figure 3 and Figure 4 Figure 4 , a support member 18 is also fixedly installed on the device body 1. The support member 18 is arranged below the rotating disk 13 and extends along the moving direction of the bolts. The gaskets sleeved on the bolts abut against the support member 18. An arc-shaped sliding groove 19 is formed on the support member 18. The rod parts of the bolts extend into the arc-shaped sliding groove 19. The distance between the support member 18 and the rotating disk 13 gradually decreases as the bolts move. Along with the movement of the bolts, the gaskets on the rod parts of the bolts gradually approach the heads of the bolts.

[0033] Reference Figure 3 and Figure 4 Figure 4 , a dial rod 20 is also fixedly installed on the device body 1. The dial rod 20 is located above the rotating disk 13 and is arranged on the moving track of the bolts. The bolts sleeved with gaskets move to the position of the dial rod 20, and the dial rod 20 separates the bolts from the rotating disk 13. A second discharge track 21 is arranged below the dial rod 20. The second discharge track 21 is fixedly installed on the device body 1. The bolts falling from the rotating disk 13 enter the second discharge track 21. An outlet chute 22 is formed on the second discharge track 21. The gaskets sleeved on the bolts abut against the end face of the outlet chute 22. The rod parts of the bolts extend into the outlet chute 22. Under the action of gravity, the bolts drive the gaskets to further approach the heads of the bolts. The second discharge track 21 drives the bolts to be transmitted to the subsequent processes.

[0034] The implementation principle of the embodiments of this application is as follows: The first vibrating disk 2 operates to achieve automatic feeding of gaskets. The gaskets move along the spiral track 3 and first enter the rejection section 4. The gaskets with the convex surface fitting the end face of the spiral track 3 slide down from the rejection section 4 into the second vibrating disk 12, and the gaskets with the concave surface fitting the end face of the spiral track 3 are retained. The gaskets with the concave surface fitting the end face of the spiral track 3 continue to move forward into the straightening section 5. The gaskets located in the straightening section 5 remain upright and the concave surface of the gaskets faces away from the first vibrating disk 2. The elastic contact piece 10 at the discharge end of the straightening section 5 enables the gaskets entering the first discharge track 8 to be single and enter in sequence; The second vibrating disk 12 operates to achieve automatic feeding of bolts. The bolts enter the placement grooves 16 on the rotating disk 13 through the third discharge track 14 in sequence. The rotating motor 15 drives the rotating disk 13 to rotate. The rotation of the rotating disk 13 drives the bolts to contact the upright gaskets. The rod portion of the bolt extends into the central hole of the gasket. The gasket is successfully sleeved on the bolt and the concave surface of the gasket faces the rod portion of the bolt. As the rotation continues, the distance between the support member 18 and the rotating disk 13 gradually decreases, and the gasket gradually approaches the head of the bolt. When the rotating disk 13 drives the bolt to rotate to the lever 20, the lever 20 contacts the bolt and drives the bolt to separate from the rotating disk 13 and enter the second discharge track 21. The bottom surface of the gasket contacts the end face of the second discharge track 21, and the gasket further approaches the head of the bolt until it fits with the head of the bolt. The second discharge track 21 drives the bolt to be transmitted to the subsequent process.

[0035] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
