Description

Technical Field

[0001] The present invention relates to the technical field of grid member processing, and particularly relates to an assembly device for conical head bolt parts. Background Art

[0002] Due to its excellent spatial stress performance, high flexibility, and relatively economical and efficient construction cost, the grid structure has become the preferred structural form for many large-scale construction projects. As the core component of the grid structure, the performance and quality of grid members directly determine the stability, safety, and durability of the entire grid structure. Grid members are rod-shaped components used in grid structures, which are connected into a grid-like structure through nodes to bear various loads and effects. Grid members mainly consist of members, nodes, and supports. Members are the main load-bearing components; nodes are important components for connecting members, usually composed of welded balls, bolt balls, or steel plate nodes, etc.; supports are used to support the grid structure and transfer loads to the lower structure, and can evenly distribute the loads to each member and node to form a stable spatial stress system. The member includes a rod body, a conical head, and a bolt. During assembly, the bolt needs to be glued into the conical head in advance, then the conical head with the bolt is moved to the end of the rod body, and the connection between the conical head and the rod body is spot-welded. Subsequently, at the rod body where the spot welding is completed, the connection between the conical head and the rod body is welded by welding equipment to form a member. After welding, the member is moved into a shot blasting equipment, and the member is polished and cleaned by the shot blasting equipment. Then, the polished and cleaned member is painted, and finally, the members are bundled according to a certain quantity.

[0003] A Chinese patent document with the publication number CN110405420B discloses a processing technology for steel structure grid members, including the following steps: blanking, chamfering, rust removal, welding, removing welding slag, painting, and marking; the painting equipment includes a bracket, a member clamping device, a member painting device, a member picking device, and a collection box. Through the member clamping device, the feeding and fixing of the member are completed, and at the same time, the rotation during the member painting process is completed; through the member painting device, the painting of the member is completed; and then through the member picking device, the painted member is picked up.

[0004] The following deficiencies also exist in the above-mentioned prior art: The conical head has a large-diameter end and a small-diameter end. In order to prevent the bolt from falling off, during assembly, the bolt needs to be glued into the conical head from the large-diameter end of the conical head first, and then the large-diameter end of the conical head is aligned with the end of the member and spot-welded. When pulling out the threaded part of the bolt from the conical head for use, tools need to be used to pull out the threaded part of the bolt from the conical head for subsequent threaded connection between the bolt and the bolt ball. Since the aperture of the small-diameter end part of the conical head is small, it is time-consuming and laborious to operate. Summary of the Invention

[0005] The present invention provides an assembly device for conical head bolt parts, aiming to solve the problem in the related art that when pulling out the threaded part of the bolt from the conical head to make the bolt threadedly connected with the bolt ball, due to the small aperture at the end part of the small diameter of the conical head, it is time-consuming and laborious to operate.

[0006] The assembly device for conical head bolt parts of the present invention includes a feeding mechanism, a discharging mechanism, a loading mechanism, a picking mechanism and a spot welding mechanism, and further includes a supporting mechanism. The supporting mechanism includes an adhesive part and a plugging part. The adhesive part includes an adhesive sleeve, a positioning sleeve, an elastic part I and a locking part. The outer side of the adhesive sleeve is coated with glue and can be adhered to the inner wall of the conical head. The positioning sleeve can hold the bolt. The positioning sleeve is connected in the adhesive sleeve through the elastic part I. The locking part is rotatably connected in the adhesive sleeve and is used for locking the positioning sleeve when the elastic part I is in a compressed state. The adhesive sleeve includes a plug, a pressing part, a movable part and an elastic part II. The plug can be inserted into the conical head and contact the end of the bolt. The movable part is connected to the plug through the elastic part II. The pressing part is inserted into the plug. The movable part can extend out of the plug and limit the plug. The pressing part can push the movable part and extend into the plug.

[0007] Beneficial effects: First, the adhesive part is placed on the feeding mechanism by the discharging mechanism, then the bolt is inserted into the positioning sleeve on the adhesive part, and then the conical head is sleeved on the adhesive sleeve and the adhesive sleeve is adhered to the inner wall of the conical head. Finally, the plugging part is installed on the conical head and limits the bolt, thus completing the assembly of the grid member. When the threaded part of the bolt is passed through the conical head for subsequent use, the plugging part can be manually rotated, so that the plug on the plugging part pushes the locking part to move and releases the locking of the positioning sleeve. After pushing the pressing part to make the movable part retract into the plug and removing the plug from the conical head, the elastic part I can apply a thrust to the bolt, so that the threaded part of the bolt passes through the conical head, without the need to pull the bolt with other tools, which is time-saving and labor-saving.

[0008] Preferably, a conical surface is provided on the outer side of the adhesive sleeve, and the glue is coated on the conical surface.

[0009] The effect is that: Through the conical surface on the adhesive sleeve, it can be adapted to the inner wall of the conical head, so as to facilitate the tight adhesion of the adhesive sleeve to the inner wall of the conical head.

[0010] Preferably, the adhesive part further includes a rotating ring and a connecting part. The rotating ring is rotatably connected in the adhesive sleeve, and the rotating ring is connected to the locking part through the connecting part.

[0011] The effect is that: The rotating ring rotatably connected in the adhesive sleeve can provide support for the locking part.

[0012] Preferably, four locking parts are provided, and a circular limiting cavity is formed between the four locking parts for limiting the bolt.

[0013] The effect is that: through the circular limiting cavity formed between the four locking parts, the bolt can be limited and guided to prevent the bolt from tilting due to gravity after separating from the positioning sleeve in the horizontal state, so as to ensure that the bolt can pass through the jack on the conical head.

[0014] Preferably, a locking groove is arranged on the outer side of the positioning sleeve, and the locking part is slidably connected in the locking groove.

[0015] The effect is that: through the locking groove, when the second elastic part is in a compressed state, the positioning sleeve can be locked by the locking part.

[0016] Preferably, the locking groove includes an arc section and an opening section. The arc section is communicated with the opening section, and the opening section penetrates to the bottom of the positioning sleeve.

[0017] The effect is that: when the locking part is located in the arc section, the locking part can lock the positioning sleeve. At this time, the second elastic part is in a compressed state. When the locking part moves to the opening section, the locking of the positioning sleeve by the locking part is released, and the second elastic part can push the positioning sleeve to move the bolt in the direction of the small-diameter end of the conical head.

[0018] Preferably, a damping block is connected inside the bonding sleeve, and the damping block is in contact with the inner wall of the positioning sleeve.

[0019] The effect is that: through the damping block, after the locking of the positioning sleeve by the locking part is released, the speed of the second elastic part pushing the positioning sleeve to move can be slowed down first, providing time for the plugging member to be pulled out of the jack, so as to avoid injury to the staff caused by the first elastic part immediately pushing the bolt to move when the plugging member has not completely separated from the conical head.

[0020] Preferably, a channel is arranged on the plug, and the movable part is slidably connected in the channel.

[0021] Preferably, a slope is arranged on the movable part, and the pressing part is in contact with the slope on the movable part.

[0022] The effect is that: through the pressing part, the slope on the movable part can be pushed, so that the movable part moves in the direction close to the axis of the plug, facilitating the release of the locking of the plug.

[0023] Preferably, the feeding mechanism includes a mounting frame, a feeding member and positioning parts. The feeding member is connected inside the mounting frame, and a plurality of positioning parts are provided, and all the plurality of positioning parts are connected to the feeding member.

[0024] The beneficial effects of the present invention are:

[0025] 1. First, place the bonding part on the feeding mechanism through the feeding mechanism. Then, insert the bolt into the positioning sleeve on the bonding part. Next, set the tapered head on the bonding sleeve, and bond the inner wall of the bonding sleeve to the tapered head. Finally, install the plugging part on the tapered head to limit the bolt, thus completing the assembly of the grid member. When the threaded part of the bolt passes through the tapered head for subsequent use, the plugging part can be rotated to make the plug on the plugging part push the locking part to move and release the locking of the positioning sleeve. After pushing the pressing part to make the movable part retract into the plug and removing the plug from the tapered head, the elastic part can apply a thrust to the bolt to make the threaded part of the bolt pass through the tapered head, eliminating the need to use other tools to pull the bolt, saving time and effort.

[0026] 2. Through the circular limiting cavity formed between the four locking parts, the bolt can be limited and guided to ensure that the bolt can pass through the jack on the tapered head.

[0027] 3. Through the damping block in contact with the positioning sleeve, after the locking of the positioning sleeve by the locking part is released, the speed of the elastic part two pushing the positioning sleeve can be slowed down first, providing time for the plugging part to be pulled out from the jack, so as to avoid hurting the staff when the elastic part one immediately pushes the bolt to move before the plugging part is completely separated from the tapered head.

[0042] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0043] As Figures 1 to 12As shown in the figure, the assembly device for the tapered head bolt parts of the present invention includes a feeding mechanism 1, a supporting mechanism 6, a blanking mechanism 2, a loading mechanism 3, a picking mechanism 4, and a spot welding mechanism 5. Through an external conveying device (the external conveying device is a prior art and is not shown in the figure), the rod body 90 can be conveyed onto the loading mechanism 3, and the loading mechanism 3 supports the rod body 90. Two feeding mechanisms 1 are provided, and the two feeding mechanisms 1 are respectively located on both sides of the loading mechanism 3. Two blanking mechanisms 2 are provided, and the two blanking mechanisms 2 are respectively arranged in cooperation with the two feeding mechanisms 1. The blanking mechanism 2 can successively place the supporting mechanism 6, the bolt 80, and the tapered head 70 onto the feeding mechanism 1, and fix the bolt 80 in the tapered head 70 through the supporting mechanism 6. By manually driving the supporting mechanism 6, the bolt 80 can be pushed, so that the threaded part of the bolt 80 automatically extends out of the small-diameter end part of the tapered head 70, which is time-saving and labor-saving. Two picking mechanisms 4 are provided, and the two picking mechanisms 4 are respectively installed on both sides of the loading mechanism 3. After the bolt 80 is fixed in the tapered head 70, the picking mechanism 4 can pick up the tapered head 70 with the bolt 80 therein and move it to the end of the rod body 90. The spot welding mechanism 5 can perform spot welding on the connection between the tapered head 70 and the rod body 90 to prevent the tapered head 70 at the end of the rod body 90 from falling off when the rod body 90 moves to the welding equipment.

[0044] When assembling the grid members, first, the external conveying device conveys the rod body 90 onto the loading mechanism 3, and the loading mechanism 3 supports the rod body 90. Then, the blanking mechanism 2 places the supporting mechanism 6, the bolt 80, and the tapered head 70 onto the feeding mechanism 1 one by one, and the supporting mechanism 6 fixes the bolt 80 in the tapered head 70. Subsequently, the picking mechanism 4 picks up the tapered head 70 with the bolt 80 fixed therein and moves the tapered head 70 to the end of the rod body 90. Finally, the spot welding mechanism 5 performs spot welding on the connection between the tapered head 70 and the rod body 90, thereby completing the assembly among the tapered head 70, the bolt 80, and the rod body 90.

[0045] Such as Figures 1 to 5As shown in the figure, the feeding mechanism 1 includes a mounting frame 11, a feeding member 12 and a positioning portion 13. The feeding member 12 is installed in the mounting frame 11 and is used to support and feed the supporting mechanism 6, the tapered head 70 and the bolt 80. After the bolt 80 is fixed in the tapered head 70 through the supporting mechanism 6, the tapered head 70 containing the bolt 80 is moved to the picking mechanism 4, and the picking mechanism 4 picks up the tapered head 70 containing the bolt 80 and moves the tapered head 70 to the end of the rod body 90, so as to facilitate subsequent spot welding of the connection between the tapered head 70 and the rod body 90. The feeding member 12 includes a motor, a conveyor belt and two driving rollers. The two driving rollers are respectively rotatably connected to both ends inside the mounting frame 11. The conveyor belt is drivingly connected between the two driving rollers. The motor is connected to the mounting frame 11, and the output shaft of the motor is connected to one of the driving rollers. Starting the motor can drive the transmission between the conveyor belt and the two driving rollers. The positioning portion 13 is provided in a plurality, and the plurality of positioning portions 13 are equidistantly connected to the outside of the conveyor belt and are used to position the supporting mechanism 6. The loading mechanism 3 includes a frame body 31 and a supporting member 32. The supporting member 32 is connected to the frame body 31 and is used to support the rod body 90.

[0046] When assembling the grid members, the supporting mechanism 6 is first placed on the positioning portion 13 of the conveyor belt through the feeding mechanism 2, and the supporting mechanism 6 is positioned by the positioning portion 13. Then the bolt 80 is placed in the supporting mechanism 6, and finally the tapered head 70 is sleeved outside the supporting mechanism 6, and the supporting mechanism 6 is adhered to the inner wall of the tapered head 70, so as to fix the bolt 80 in the tapered head 70. Subsequently, the feeding member 12 is started to convey the tapered head 70 to the picking mechanism 4, and the picking mechanism 4 picks up the tapered head 70 containing the bolt 80 and moves the tapered head 70 to the end of the rod body 90.

[0047] As shown in Figure 2 , Figures 5 to 12 the figure, a jack 701 is provided at the small-diameter end portion of the tapered head 70 for the threaded portion of the bolt 80 to pass through the small-diameter end portion of the tapered head 70. The supporting mechanism 6 includes an adhesive member 61 and a plugging member 62. The adhesive member 61 can be adhered inside the tapered head 70 and support the bolt 80, so that the bolt 80 is coaxially arranged with the tapered head 70, and the threaded portion of the bolt 80 faces upward. The plugging member 62 can plug the jack 701 and be in close contact with the top of the bolt 80, so as to fix the bolt 80 in the tapered head 70. When using the bolt 80, the plugging member 62 is taken out from the jack 701 at the small-diameter end portion of the tapered head 70 and the adhesive member 61 is driven, so that the adhesive member 61 pushes the threaded portion of the bolt 80 to pass through the jack 701, which is time-saving and labor-saving.

[0048] Continuing to refer to Figure 2 , Figures 5 to 12As shown, the bonding member 61 includes a bonding sleeve 611, a positioning sleeve 612, a first elastic part 613, a rotating ring 615, a connecting part 616, a locking part 617 and a damping block 618. The bonding sleeve 611 is sleeved on the positioning part 13. The outer side of the bonding sleeve 611 is a conical surface, which is adapted to the inner wall of the conical head 70. Glue can be coated on the conical surface of the bonding sleeve 611 through an external glue coating device (the external glue coating device is a prior art and is not shown in the figure), so that the bonding sleeve 611 can be bonded to the inner wall of the conical head 70. The positioning sleeve 612 is arranged in the bonding sleeve 611. The first elastic part 613 is connected between the positioning sleeve 612 and the bonding sleeve 611. The first elastic part 613 is a compression spring. A locking groove 614 is arranged on the outer side of the positioning sleeve 612. There are four locking grooves 614. The locking groove 614 is provided with an arc section and an opening section. The arc section and the opening section are communicated, and the opening section penetrates to the bottom of the positioning sleeve 612. The rotating ring 615 is rotatably connected in the bonding sleeve 611. There are four locking parts 617 and four connecting parts 616. The four locking parts 617 are connected to the rotating ring 615 through the four connecting parts 616. The four locking parts 617 are respectively slidably connected with the four locking grooves 614;

[0049] When the locking part 617 slides in the arc section of the locking groove 614, the locking part 617 can lock the positioning sleeve 612, and the first elastic part 613 is in a compressed state. When the locking part 617 moves to the opening section, the locking part 617 releases the locking of the positioning sleeve 612. At this time, the first elastic part 613 can push the positioning sleeve 612 to move towards the small-diameter end part of the conical head 70, and the positioning sleeve 612 pushes the bolt 80, so that the threaded part of the bolt 80 passes through the jack 701 on the conical head 70. A circular limiting cavity is formed between the four locking parts 617, and the inner diameter of the circular limiting cavity is equal to the outer diameter of the large head of the bolt 80. The bolt 80 can be limited through the circular limiting cavity to prevent the bolt 80 from tilting due to gravity after being separated from the positioning sleeve 612 in the horizontal state, so as to ensure that the threaded part of the bolt 80 can pass through the jack 701 on the conical head 70. The damping block 618 is connected in the bonding sleeve 611, and the damping block 618 is in contact with the inner wall of the positioning sleeve 612. The damping block 618 can slow down the moving speed of the first elastic part 613 pushing the positioning sleeve 612 after the locking part 617 releases the locking of the positioning sleeve 612, and after the damping block 618 is separated from the positioning sleeve 612, the first elastic part 613 speeds up the moving speed of pushing the positioning sleeve 612, so as to avoid hurting the staff when the elastic part 613 immediately pushes the bolt 80 to move before the plugging member 62 is completely separated from the conical head 70.

[0050] Continue to refer to Figure 2 、 Figures 5 to 12As shown, the plugging member 62 includes a plug head 621, a pressing portion 623, a movable portion 624, and a second elastic portion 625. The plug head 621 is inserted into the jack 701, and the plug head 621 is in a T shape. One end of the plug head 621 extending into the jack 701 is in contact with the end of the bolt 80. Four channels 622 are provided on the outer side of the plug head 621, and one end of the channel 622 is communicated with the inner side of the plug head 621. The pressing portion 623 is inserted into the end of the plug head 621 extending out of the jack 701, and the pressing portion 623 is slidably connected with the four channels 622. The movable portions 624 are provided in four numbers, and the four movable portions 624 are respectively slidably connected in the four channels 622. The second elastic portion 625 is a compression spring, and the second elastic portion 625 is provided in four numbers. The four movable portions 624 are respectively connected with the plug head 621 through the four second elastic portions 625. Through the second elastic portion 625, the movable portion 624 can extend out of the channel 622 and contact the abutting surface 702, so as to lock the plug head 621 at the small-diameter end portion of the tapered head 70, and further block and limit the top of the bolt 80 to realize the fixation of the bolt 80. The top of the movable portion 624 is provided with an inclined surface, and the pressing portion 623 is in contact with the inclined surface at the top of the movable portion 624. When the pressing portion 623 moves downward, it can push the inclined surface of the movable portion 624, so that the movable portion 624 moves toward the direction close to the central axis of the plug head 621 and compresses the second elastic portion 625 until one end of the movable portion 624 extending out of the channel 622 completely enters the channel 622, thus releasing the lock on the plug head 621, so as to facilitate the removal of the plug head 621 from the small-diameter end portion of the tapered head 70. When the plug head 621 plugs the jack 701 at the small-diameter end portion of the tapered head 70, the jack 701 can be closed through the plug head 621 to prevent the paint from entering the tapered head 70 from the jack 701 and adhering to the threaded portion of the bolt 80 during the subsequent painting process, thereby affecting the subsequent use of the bolt 80.

[0051] Working principle:

[0052] Start the external conveying device to convey the rod body 90 to the loading mechanism 3 for subsequent assembly.

[0053] Start the external glue application device to apply glue on the conical surface of the bonding sleeve 611.

[0054] Start the feeding mechanism 2 to clamp and move the bonding sleeve 611 until the bonding sleeve 611 is sleeved on the positioning portion 13.

[0055] Start the feeding mechanism 2 to clamp and move the bolt 80 so that the bolt 80 is inserted into the positioning sleeve 612 inside the bonding sleeve 611.

[0056] Start the feeding mechanism 2 to clamp and move the tapered head 70 so that the tapered head 70 is sleeved on the outside of the bonding sleeve 611, and the bonding sleeve 611 is adhesively fixed to the inner wall of the tapered head 70 through the glue applied on its conical surface.

[0057] Start the discharging mechanism 2 to clamp the plug 621 and push the pressing part 623 downward. The downward movement of the pressing part 623 can push the inclined surface of the movable part 624, so that the movable part 624 moves towards the direction close to the central axis of the plug 621, and compress the second elastic part 625 until one end of the movable part 624 extending out of the channel 622 completely enters the channel 622. Subsequently, the discharging mechanism 2 inserts the plug 621 into the jack 701 at the small-diameter end of the tapered head 70. Then, release the pressing part 623. At this time, under the elastic force of the second elastic part 625, the second elastic part 625 pushes the movable part 624 to move away from the axis of the plug 621 until the movable part 624 extends out of the channel 622 and contacts the abutting surface 702, thereby locking the plug 621 at the small-diameter end of the tapered head 70. At this time, the two ends of the bolt 80 are blocked and limited by the plug 621 and the positioning sleeve 612, and then the bolt 80 is fixed in the tapered head 70.

[0058] Start the feeding mechanism 1 to convey the tapered head 70 equipped with the bolt 80 to the picking mechanism 4. Then, start the picking mechanism 4 to pick up the tapered head 70 equipped with the bolt 80 and drive the tapered head 70 to move to the end of the rod body 90. Finally, start the spot welding mechanism 5 to perform spot welding on the connection between the tapered head 70 and the rod body 90.

[0059] When using the grid frame members, the threaded portion of the bolt 80 needs to pass through the insertion hole 701 at the small-diameter end of the conical head 70 for subsequent installation. The staff can first turn the plug 621 to make the movable portion 624 push the locking portion 617 to rotate until the locking portion 617 moves from the arc section of the locking groove 614 to the opening section. Then, push the pressing portion 623 to make the pressing portion 623 push the inclined surface of the movable portion 624, so that the movable portion 624 moves towards the direction close to the central axis of the plug 621 and compresses the second elastic portion 625 until one end of the movable portion 624 extending out of the channel 622 completely enters the channel 622, thereby releasing the locking of the plug 621 and removing the plug 621 from the insertion hole 701 at the small-diameter end of the conical head 70. At this time, the first elastic portion 613 in the compressed state pushes the positioning sleeve 612 to make the bolt 80 move towards the direction close to the small-diameter end of the conical head 70, and the damping block 618 reduces the moving speed of the positioning sleeve 612, so that the staff has enough time to remove the unlocked plug 621 from the insertion hole 701. After the damping block 618 is separated from the positioning sleeve 612, the first elastic portion 613 accelerates the speed of pushing the positioning sleeve 612 to make the positioning sleeve 612 apply a thrust to the bolt 80, so that the threaded portion of the bolt 80 passes through the insertion hole 701 at the small-diameter end of the conical head 70. And after the bolt 80 is separated from the positioning sleeve 612, the circular limiting cavity formed between the four locking portions 617 limits and guides the bolt 80 to ensure that the threaded portion of the bolt 80 can pass through the insertion hole 701 on the conical head 70.

[0060] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
