Description

Technical Field

[0001] The present invention relates to the technical field of cold heading machines, and particularly relates to a tooth tube maintenance device for a cold heading machine. Background Art

[0002] A cold heading machine is a special device mainly used for mass-producing fasteners such as nuts and bolts by heading. A tooth tube is usually installed inside the cold heading machine. The function of the tooth tube is to form threads on fasteners such as nuts and bolts during the cold heading process. However, after long-term use, the tooth tube will be damaged and worn flat, and there may even be problems such as the tooth tube bursting and the tooth path getting stuck. At this time, a tooth tube maintenance device is needed to repair the tooth tube to ensure the normal processing work of the tooth tube of the cold heading machine.

[0003] However, the maintenance head in the existing tooth tube maintenance devices on the market is often fixed on the machine table. Usually, several tooth tubes are installed on a cold heading machine. At the same time, customers have requirements for thread processing of fasteners such as nuts and bolts with different diameters and pitches. At this time, different specifications of tooth tubes need to be installed inside the cold heading machine. However, the existing maintenance devices cannot adjust the position according to different specifications of tooth tubes during the maintenance process, resulting in problems of low automation and adaptability. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a tooth tube maintenance device for a cold heading machine with high versatility and capable of adapting to different specifications of tooth tubes in view of the above-mentioned deficiencies of the prior art.

[0005] To achieve the above object, the present invention provides the following technical solution: A tooth tube maintenance device for a cold heading machine, including a machine table and a maintenance head arranged on the machine table, characterized in that: a first sliding component is arranged on the upper end surface of the machine table along its length direction, the sliding component includes a slider connected to the maintenance head and a driving structure capable of driving the slider to reciprocate along the length direction of the machine table; a second sliding component is arranged between the slider and the maintenance head, and the second sliding component can drive the maintenance head to reciprocate along the width direction of the machine table on the slider.

[0006] Adopting the above technical solution: Compared with the prior art where the position cannot be adjusted according to different specifications of tooth tubes during the maintenance process, the present invention can realize the reciprocating movement adjustment of the maintenance head along the length and width directions of the machine table through the first sliding component and the second sliding component, so that the maintenance head can adjust its position according to tooth tubes of different lengths, improving the adaptability and the maintenance efficiency at the same time.

[0007] A further arrangement of the present invention is that: the driving structure includes sliding rods arranged oppositely and connected to both ends of the machine table at both ends respectively, and a chassis located at one end of the machine table. The slider is slidably arranged on the sliding rod. A driving motor is arranged in the chassis. One end of the sliding rod close to the chassis can pass through the chassis. The output end of the driving motor is linked with a first transmission screw rod. The other end of the first transmission screw rod far from the driving motor is rotatably arranged on the machine table, and the first transmission screw rod is located between the sliding rods. The first transmission screw rod passes through the slider and is in threaded transmission connection with the slider.

[0008] Adopting the above technical solution: through the arrangement of the driving motor and the first transmission screw rod, and the first transmission screw rod passes through the slider and is in threaded transmission connection with the slider. During use, by starting the driving motor to drive the first transmission screw rod to rotate, the slider can be promoted to move along the first transmission screw rod, realizing the position adjustment of the maintenance head, and improving the degree of automation; at the same time, due to the arrangement of the chassis, the driving motor can be protected and the function of dust prevention can be achieved.

[0009] A further arrangement of the present invention is that: first limit blocks are oppositely arranged on one side of the slider close to the chassis. A limit rod extends towards the chassis on the first limit block. A second limit block is arranged on the chassis corresponding to the first limit block. A through hole for the limit rod to pass through is opened on the second limit block, and the first limit block and the second limit block can abut against each other.

[0010] Adopting the above technical solution: through the arrangement of the first limit block, the limit rod and the second limit block, when the slider drives the maintenance head to move towards the chassis, a limiting function can be achieved to prevent the maintenance head and the slider from hitting the chassis.

[0011] A further arrangement of the present invention is that: the second sliding component includes a mounting block arranged on the upper end surface of the slider. The maintenance head is detachably connected with a mounting plate through the bottom of the mounting frame. Fixing plates are fixedly connected to both ends of the mounting plate. A second transmission screw rod is rotatably connected between the fixing plates. Rotating handles are linked to both ends of the second transmission screw rod. A groove is arranged on the mounting block. A transmission block is fixedly connected to the bottom of the groove of the groove. A first screw hole is arranged on the transmission block. The second transmission screw rod passes through the first screw hole and is in threaded transmission connection with the first screw hole.

[0012] Adopting the above technical solution: through the threaded transmission connection arrangement of the transmission block and the second transmission screw rod, since the two ends of the second transmission screw rod are rotatably connected to the fixing plates at both ends of the mounting plate, and the transmission block is fixedly connected in the mounting block, when rotating the rotating handle to link the second transmission screw rod, the mounting plate can be driven to move along the mounting block, so as to promote the position adjustment of the maintenance head to correspond to the dental tubes at different positions for maintenance, which is convenient for the staff to use.

[0013] A further arrangement of the present invention is that sliding steps are provided on both sides of the transmission block where the groove is located. On the side of the mounting plate close to the mounting block, sliding blocks are provided corresponding to the sliding steps. The sliding blocks are located on the sliding steps and can reciprocate along the sliding steps.

[0014] With the above technical solution: Through the arrangement of the sliding steps on the mounting block and the sliding blocks on the mounting plate, during use, the sliding blocks are located on the sliding steps and can reciprocate along the sliding steps, which not only ensures the sliding effect of the mounting plate on the mounting block, but also the sliding steps play a certain guiding role.

[0015] A further arrangement of the present invention is that a mounting portion is provided at the bottom of the mounting frame. At least one first mounting groove is opened at both ends of the mounting portion. A plurality of second mounting grooves corresponding to the first mounting grooves are provided on the upper end surface of the mounting plate.

[0016] With the above technical solution: Through the arrangement of the mounting portion, the first mounting groove and the second mounting groove, during assembly, after the first mounting groove and the second mounting groove are aligned, the fastener is inserted for fixation, thereby realizing the assembly. At the same time, due to the arrangement of a plurality of second mounting grooves, the front and rear positions of the maintenance machine head can be finely adjusted and repaired.

[0017] A further arrangement of the present invention is that a hydraulic lifting mechanism is provided on the bottom surface of one end of the machine table.

The output end of the hydraulic cylinder is hinged to the connecting block. The base is provided with a hydraulic pump connected to the hydraulic cylinder. The hydraulic pump is a manual hydraulic pump. The manual hydraulic pump is provided with a lifting operation foot pedal and a lowering operation handle.

[0018] With the above technical solution: Through the arrangement of the base, the lifting platform and the scissors frames, during use, the oil pump of the hydraulic pump transports the oil in the external oil storage tank to the hydraulic cylinder through the oil pipe. The hydraulic cylinder pushes the connecting block to drive the connecting rod to rotate, thereby driving the scissors frames to lift. Further, the scissors frames drive the lifting platform to lift, completing the function that the maintenance machine head can lift. In addition, through the lifting operation handle and the lowering operation foot pedal provided on the manual hydraulic pump, it is convenient to manually control the lifting of the lifting platform.

[0019] A further setting of the present invention is that at least one connecting block is fixedly provided on both sides of the machine platform near one end of the lifting platform, and the connecting block extends outward.
