Technical Field

[0001] The utility model relates to the field of production and assembly of skipping ropes, in particular to a skipping rope handle assembly machine. Background Art

[0002] The usual skipping rope handles, see Figure 4 , including a handle and a rope cap, which are connected together by threaded fitting. At present, the skipping rope handle is assembled manually. Due to the tightness of the threaded fitting and the angle matching between the rope cap and the handle, the existing manual operation has the following problems: First, the assembly efficiency is low, and it is difficult to meet the requirements of the automated production of the skipping rope handle; second, since different operators are difficult to control the tightening force of the thread when assembling the skipping rope handle, the tightness between the handle and the rope cap of the assembled skipping rope handle is inconsistent, and the quality of assembly is difficult to ensure uniformity; third, during the assembly of the skipping rope handle, when the rope cap is manually tightened, sweat and grease on the fingers are easily adhered to the rope cap, affecting the appearance of the skipping rope handle. Utility Model Content

[0003] In view of the many defects existing in the manual assembly of the skipping rope handle, in order to meet the requirements of rapid assembly of the skipping rope handle and improve the efficiency and quality stability of the skipping rope handle assembly, the utility model provides a skipping rope handle assembly machine.

[0004] The technical solution provided by the utility model is: a skipping rope handle assembly machine, including a machine base, the machine base is provided with a bottom plate and a top plate arranged opposite to each other up and down, the bottom plate and the top plate are supported by a plurality of support rods, a plurality of assembly stations are arranged between the bottom plate and the top plate, each of the assembly stations includes a handle socket connected to the bottom plate, a handle slot is provided on the handle socket, a grip pre-installed with a rope cap is plugged and fixed vertically through the handle slot, a support is provided at the rear end of the handle socket, a claw cylinder is installed on the support, and a pair of rotatable The gripping claws, by means of the gripping claw cylinder, a pair of the gripping claws rotate relative to each other and clamp the handle, the top plate, a downward pressure cylinder is installed on it, the telescopic rod of the downward pressure cylinder is connected to a lifting mechanism through the top plate, the lifting mechanism includes a first lifting plate, a servo motor is arranged on the first lifting plate, a three-jaw clamping cylinder is connected to the power output shaft of the servo motor, the three-jaw clamping cylinder is provided with openable and closable clamping claws, the lifting mechanism lowers the clamping claws to the rope cap by means of the downward pressure cylinder, the three-jaw clamping cylinder clamps the rope cap through the clamping claws, and the servo motor rotates the three-jaw clamping cylinder to realize the threaded connection of the rope cap on the handle.

[0005] Furthermore, the lifting mechanism is provided with two sliding rods, the top plate is provided with a first linear bearing corresponding to the sliding rod, the sliding rod is sleeved in the first linear bearing, and a sliding connection is formed between the sliding rod and the top plate by means of the first linear bearing. Furthermore, through the sliding connection of the first linear bearing, the lifting mechanism can better achieve up and down positioning and sliding, ensuring that the lifting mechanism accurately positions the clamping claw to pre-send it around the outer periphery of the rope cap of the rope skipping handle.

[0006] Furthermore, the lifting mechanism further includes a second lifting plate, and the second lifting plate is elastically connected to the first lifting plate through a spring. After the downward pressure cylinder quickly lowers the lifting mechanism, the clamping claws of the three-claw clamping cylinder clamp the rope cap of the rope skipping handle, and the rope cap is screwed in under the rotation of the servo motor. At the same time, when the rope cap is screwed into the handle, the rope cap will drop with the pitch. Therefore, through the elastically set first lifting plate, when the height position of the second lifting plate remains unchanged, the first lifting plate is stretched by the spring so that the position of the first lifting plate can be kept consistent with the descending position of the rope cap.

[0007] Furthermore, the first lifting plate is provided with a plurality of sleeve rods corresponding to the springs, and the second lifting plate is provided with a plurality of second linear bearings corresponding to the sleeve rods, and the sleeve rods are sleeved inside the springs and pass through the outside of the second linear bearings.

[0008] Furthermore, a triangular cone-shaped clamping groove is provided on the clamping claw. When the two clamping claws of the clamping claw cylinder rotate relative to each other and clamp, a clamping space for the grip to be clamped is formed between the clamping grooves of the two clamping claws, which further fixes the grip.

[0009] Furthermore, the gripping claw is made of rubber material. The gripping claw made of rubber material will not damage the gripping handle during the process of clamping the gripping handle, and the rubber material has a large resistance, and after clamping, the rope cap will not rotate during the process of being screwed into the gripping handle.

[0010] Furthermore, the bottom plate and the top plate are provided with two assembly stations. Therefore, the assembly machine of the rope skipping handle only needs one person to operate, and while one assembly station manually places and fixes the rope skipping handle or manually takes out the rope skipping handle, the other assembly station can simultaneously quickly assemble the rope skipping handle, and the rotation cooperation between man and machine can greatly improve the assembly efficiency of the rope skipping handle.

[0011] The utility model discloses a method for manually pre-installing a rope cap and a handle of a rope skipping handle when assembling the handle and the rope cap. The pre-installation refers to pre-placing the rope cap on the handle and rotating it twice so that the rope cap can be positioned so as not to be loosened from the handle. The pre-installed rope skipping handle is inserted into the handle slot of the handle socket, with the rope cap of the rope skipping handle facing upward. The handle of the rope skipping handle is further clamped and fixed by a claw cylinder. Then, the lifting mechanism is lowered by pressing down the cylinder so that the claws of a three-claw clamping cylinder installed on the lifting mechanism surround the outer side of the rope cap. After the rope cap is clamped by the claws of the three-claw clamping cylinder, the servo motor is started, and the servo motor drives the three-claw clamping cylinder to rotate. The screwing degree of the rope cap on the handle can be controlled by controlling the number of rotations of the servo motor, thereby achieving a uniform and consistent screwing effect of the rope cap when the handle is assembled.

[0012] The utility model provides a lifting mechanism by arranging a first lifting plate and a second lifting plate, and the first lifting plate and the second lifting plate are elastically connected by a spring, so that in the process of the three-claw clamp cylinder clamping and rotating the rope cap, the first lifting plate is elastically stretched and lowered to maintain the position moved by the spiral descending of the rope cap, thereby achieving the purpose of screwing the rope cap into the handle.

[0013] The utility model can realize the operation by one person through the arrangement of a plurality of assembly stations, and the assembly efficiency of the rope skipping handle can be greatly improved through the rotation cooperation between man and machine. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The following is a brief description of the implementation of the present utility model in conjunction with the accompanying drawings.

[0020] A skipping rope handle assembly machine, referring to 1- Figure 3 , including a machine base 1, the machine base 1 is provided with a bottom plate 11 and a top plate 12 arranged opposite to each other, the bottom plate 11 and the top plate 12 are supported by a plurality of support rods 13, a plurality of assembly stations are arranged between the bottom plate 11 and the top plate 12, each assembly station includes a handle socket 2 connected to the bottom plate 11, a handle slot 21 is provided on the handle socket 2, a grip 81 pre-installed with a rope cap 82 is inserted and fixed vertically through the handle slot 21, refer to Figure 4 Pre-installation means that the rope cap 82 is pre-installed on the handle 81 and rotated twice so that the rope cap 82 can be positioned and will not be loosened from the handle 81.

[0021] A support 14 is provided at the rear end of the handle socket 2, and a claw cylinder 3 is installed on the support 14. A pair of rotatable claws 31 extend from the front end of the claw cylinder 3 in the direction of the grip 81. Figure 2 A triangular cone-shaped clamping groove 32 is provided on the clamping claw 31. When the two clamping claws 31 of the clamping claw cylinder 3 rotate relative to each other and clamp, a clamping space for the handle 81 to be clamped is formed between the clamping grooves 32 of the two clamping claws 31. Through the clamping claw cylinder 3, a pair of clamping claws 31 rotate relative to each other and clamp the handle 81 using the two clamping grooves 32. After the handle 81 is clamped and fixed by the clamping claw cylinder 3, the handle 81 is completely fixed in the handle socket 2.

[0022] In this embodiment, the claw 31 is made of rubber material. During the assembly process of the rope cap 82 being screwed into the handle 81, the rotation of the rope cap 82 drives the rotation of the handle 81. Therefore, the rubber claw 31 is used to increase the resistance after clamping, and the rope cap 82 will not rotate during the process of being screwed into the handle 81.

[0023] The top plate 12 is provided with a pressing cylinder 6, and the telescopic rod of the pressing cylinder 6 is connected to the lifting mechanism 7 through the top plate 12. Figure 3, the lifting mechanism 7 includes a first lifting plate 71 and a second lifting plate 72, and the second lifting plate 72 is elastically connected to the first lifting plate 71 by a spring 75. In this embodiment, the elastic connection of the spring 75 refers to the connection between the two ends of the spring 75 and the first lifting plate 71 and the second lifting plate 72 by a commonly used existing connection method such as clamping or welding, so that a stretchable and compressible connection body is formed between the first lifting plate 71 and the second lifting plate 72. A servo motor 5 is provided on the first lifting plate 71, and a three-claw clamping cylinder 4 is connected to the power output shaft of the servo motor 5. The three-claw clamping cylinder 4 is provided with a clamping claw 41 that can be opened and closed. Through the downward pressure cylinder 6, the lifting mechanism 7 lowers the clamping claw 41 of the three-claw clamping cylinder 4 to the rope cap 82, and the three-claw clamping cylinder 4 is connected to the power output shaft of the servo motor 5. The claw clamp cylinder 4 clamps the rope cap 82 through the clamp claw 41, and the servo motor 5 rotates the three-claw clamp cylinder 4 to realize the threaded connection of the rope cap 82 on the handle 81. During assembly, the servo motor 5 drives the three-claw clamp cylinder 4 to rotate. It is only necessary to control the number of rotations of the servo motor 5 to control the degree of screwing of the rope cap 82 on the handle 81, thereby achieving a uniform and consistent screwing effect of the rope cap 82 when assembled on the handle 81. During the process of screwing the rope cap 82 into the handle 81, the rope cap 82 will decrease with the pitch. Therefore, through the elastically set first lifting plate 71, while the second lifting plate 72 ensures that the height position remains unchanged, the first lifting plate 71 is stretched by the spring 75 so that the position of the first lifting plate 71 can follow the descending position of the rope cap 82 and remain consistent.

[0024] Among them, the lifting mechanism 7 is provided with two sliding rods 16, the sliding rods 16 are connected to the second lifting plate 72 of the lifting mechanism 7, and the top plate 12 is provided with a first linear bearing 15 corresponding to the sliding rod 16, and the sliding rod 16 is sleeved in the first linear bearing 15. Through the first linear bearing 15, a sliding connection is formed between the sliding rod 16 and the top plate 12. Therefore, the lifting mechanism 7 can better realize the up and down positioning and sliding, and ensure that the lifting mechanism 7 accurately positions the clamping claw 41 and pre-sends it around the outer periphery of the rope cap 82 of the skipping rope handle 8.

[0025] To ensure accurate positioning of the elastic connection between the first lifting plate 71 and the second lifting plate 72, in the present embodiment, a plurality of sleeve rods 74 corresponding to the springs 75 are provided on the first lifting plate 71, and a plurality of second linear bearings 73 corresponding to the sleeve rods 74 are provided on the second lifting plate 72. The sleeve rods 74 are sleeved inside the springs 75 and pass through the outside of the second linear bearings 73. Through the sliding connection of the sleeves 74 on the second linear bearings 73, the first lifting plate 71 can better ensure stable positioning during the descending process of the three-claw clamping cylinder 4 rotating the rope cap 82, so that the rope cap 82 will not be eccentric, ensuring that the rope cap 82 can be tightened according to the rotation direction of the thread when screwed in.

[0026] In this embodiment, a plurality of assembly stations can be set between the bottom plate 11 and the top plate 12. Preferably, two assembly stations can be set. Therefore, each skipping rope handle assembly machine only needs one person to operate. While the skipping rope handle 8 is manually placed or manually removed at one assembly station, the skipping rope handle 8 can be quickly assembled at another assembly station at the same time. Through the rotation cooperation between man and machine, the assembly efficiency of the skipping rope handle 8 can be greatly improved.

[0027] The above embodiments only express the implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
