Description

Technical Field

[0001] This utility model relates to the technical field of tie rod processing equipment, and in particular to a position adjustment device for tie rods. Background Technology

[0002] Pull handles are common components in suitcases, primarily assisting users in lifting and pulling the suitcase, thus saving effort. Since users have different heights and arm lengths, the extension length of the pull handle varies. To facilitate user use, several fixing holes are usually drilled on the pull handle for secure fixing. Currently, workers manually place the pull handle to be processed onto a fixing fixture before drilling. However, this method has the following problems: because the cross-sectional shape of the pull handle is not square or rectangular, but may be an irregular polygon, such products are particularly prone to defects. Before each drilling, workers need to check whether the pull handle is correctly positioned, especially the top and bottom orientation. After long periods of work, workers may become fatigued and prone to incorrect pull handle placement, leading to defective products. Therefore, a new pull handle position adjustment device is needed to improve production efficiency and product qualification rate. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a highly automated position adjustment device for tie rods that can improve production efficiency and product qualification rate.

[0004] The technical solution of this utility model: A position adjustment device for a pull rod, comprising a device base, a fixed base connected to the device base, a plurality of first clamping plates slidably connected to the fixed base, a plurality of second clamping plates slidably connected to the fixed base, a first hydraulic cylinder for driving the first clamping plates to move horizontally, a second hydraulic cylinder for driving the second clamping plates to move horizontally, a baffle fixedly connected to the device base, a sliding base slidably connected to the device base, a first clamping rod movably connected to the baffle, a second clamping rod movably connected to the sliding base, and a mechanism for driving the sliding base. The equipment includes a third hydraulic cylinder that moves horizontally along the base, a first rotary motor that drives the first clamping rod to rotate, a second rotary motor that drives the second clamping rod to rotate, a CCD vision inspection instrument and a controller connected to the equipment base, the first clamping plate and the second clamping plate moving towards each other, the movement direction of the sliding base being perpendicular to the first clamping plate and the second clamping plate respectively, the rotation direction of the first clamping rod and the second clamping rod being the same, and the controller being electrically connected to the first hydraulic cylinder, the second hydraulic cylinder, the third hydraulic cylinder, the first rotary motor, the second rotary motor and the CCD vision inspection instrument respectively.

[0005] Using the above technical solution, firstly, the tie rod to be processed is placed on a fixed base. Then, the controller controls the first and second hydraulic cylinders to drive the first and second clamping plates to move towards each other, thereby clamping the tie rod. Next, the controller controls the third hydraulic cylinder to drive the sliding base to move towards the baffle, so that both ends of the tie rod are clamped by the first and second clamping rods respectively. Then, the first and second clamping plates are reset. The position of the tie rod is detected by a CCD vision inspection instrument and compared with the standard processing and placement state of the tie rod stored in the CCD vision inspection instrument. If the two match, no position adjustment is required, and subsequent drilling work can be carried out directly. If the position does not match, the CCD vision inspection instrument sends an electrical signal to the controller, and the controller controls the first rotary motor to rotate a certain angle until the tie rod is in the correct position. This can significantly reduce labor costs, ensure that the tie rod to be processed is in the correct orientation, and thus reduce the defect rate. A further feature of this invention is that both the first clamping rod and the second clamping rod are provided with fixing blocks, and the cross-sectional shape of the fixing blocks is adapted to the cross-sectional shape and size of the pull rod to be processed.

[0006] By adopting the above technical solution, since the cross-sectional shape of the fixing block is compatible with the cross-sectional shape and size of the pull rod to be processed, when adjusting the position of the pull rod, the fixing block is inserted into the hollow groove inside the pull rod, which can further ensure the positional stability of the pull rod when rotating, thereby improving the accuracy of subsequent processing of the pull rod and thus improving the product qualification rate.

[0007] Further features of this invention: The fixed base is provided with a fixed groove, and the fixed groove is provided with a support base slidably connected to the fixed groove and a fourth hydraulic cylinder for driving the support base to move in the vertical direction. The fixed base is also provided with a clamping block hinged to the fixed base and a third rotary motor for driving the clamping block to rotate. The support base and the clamping block are respectively provided with a first limiting groove and a second limiting groove. The first limiting groove and the second limiting groove are respectively adapted to the shape and size of the pull rod to be processed. The controller is electrically connected to the fourth hydraulic cylinder and the third rotary motor.

[0008] Using the above technical solution, after the first and second clamping rods clamp both ends of the pull rod respectively, the first and second clamping plates reset. Simultaneously, the controller controls the fourth hydraulic cylinder to drive the support base to move vertically downward, allowing the pull rod to rotate more easily. Once the pull rod is adjusted to the correct position, the controller controls the fourth hydraulic cylinder to drive the support base to move vertically upward. At the same time, the controller controls the third rotary motor to drive the clamping block to rotate at a certain angle, so that the clamping block and the support base simultaneously clamp the upper and lower sides of the pull rod. This facilitates subsequent drilling operations, ensures the positional stability of the pull rod during drilling, and thus improves the product qualification rate.

[0009] A further feature of this invention is that the inner walls of both the first limiting groove and the second limiting groove are provided with a first rubber pad and a second rubber pad, respectively, and the first rubber pad and the second rubber pad are adapted to the shape and size of the first limiting groove and the second limiting groove.

[0010] By adopting the above technical solution, since the inner walls of the first limiting groove and the second limiting groove are both provided with a first rubber pad and a second rubber pad, the rubber pads have good shock absorption and anti-slip performance, which can further improve the positional stability of the pull rod during the drilling process, thereby improving the drilling accuracy and the product qualification rate.

Detailed Implementation

[0013] like Figure 1As shown, a position adjustment device for a pull rod includes a device base 1, a fixed base 2 connected to the device base 1, a plurality of first clamping plates 3 slidably connected to the fixed base 2, a plurality of second clamping plates 4 slidably connected to the fixed base 2, a first hydraulic cylinder 5 for driving the first clamping plates 3 to move horizontally, a second hydraulic cylinder 6 for driving the second clamping plates 4 to move horizontally, a baffle 7 fixedly connected to the device base 1, a sliding base 8 slidably connected to the device base 1, a first clamping rod 9 movably connected to the baffle 7, a second clamping rod 10 movably connected to the sliding base 8, and a second clamping rod 10 for driving the sliding base 8 to move horizontally. A three-cylinder hydraulic cylinder 11, a first rotary motor 12 for driving the first clamping rod 9 to rotate, a second rotary motor 13 for driving the second clamping rod 10 to rotate, a CCD vision inspection instrument 14 and a controller 15 connected to the equipment base 1, the first clamping plate 3 and the second clamping plate 4 move towards each other, the movement direction of the sliding base 8 is perpendicular to the first clamping plate 3 and the second clamping plate 4 respectively, the rotation direction of the first clamping rod 9 and the second clamping rod 10 is the same, and the controller 15 is electrically connected to the first hydraulic cylinder 5, the second hydraulic cylinder 6, the third hydraulic cylinder 11, the first rotary motor 12, the second rotary motor 13 and the CCD vision inspection instrument 14 respectively.

[0014] First, the tie rod to be processed is placed on the fixed base 2. Then, the controller 15 controls the first hydraulic cylinder 5 and the second hydraulic cylinder 6 to drive the first clamping plate 3 and the second clamping plate 4 to move towards each other, thereby clamping the tie rod. Then, the controller 15 controls the third hydraulic cylinder 11 to drive the sliding base 8 to move towards the baffle 7, so that both ends of the tie rod are clamped by the first clamping rod 9 and the second clamping rod 10 respectively. Then, the first clamping plate 3 and the second clamping plate 4 are reset. The position of the tie rod is detected by the CCD vision inspection instrument 14 and compared with the standard processing position of the tie rod stored in the CCD vision inspection instrument 14. If the two match, no position adjustment is required, and subsequent drilling work can be carried out directly. If the position does not match, the CCD vision inspection instrument 14 sends an electrical signal to the controller 15, and the controller 15 controls the first rotary motor 12 to rotate a certain angle until the tie rod is in the correct position. This can reduce labor costs, ensure that the tie rod to be processed is in the correct orientation, and thus reduce the defect rate.

[0015] Both the first clamping rod 9 and the second clamping rod 10 are provided with fixing blocks 16, and the cross-sectional shape of the fixing blocks 16 is adapted to the cross-sectional shape and size of the pull rod to be processed.

[0016] Since the cross-sectional shape of the fixing block 16 is compatible with the cross-sectional shape and size of the pull rod to be processed, when adjusting the position of the pull rod, the fixing block 16 is inserted into the hollow groove inside the pull rod, which can further ensure the positional stability of the pull rod when rotating, thereby improving the accuracy of subsequent processing of the pull rod and thus improving the product qualification rate.

[0017] The fixed base 2 is provided with a fixed groove 17. The fixed groove 17 is provided with a support base 18 slidably connected to the fixed groove 17 and a fourth hydraulic cylinder 19 for driving the support base 18 to move in the vertical direction. The fixed base 2 is also provided with a clamping block 20 hinged to the fixed base 2 and a third rotary motor 21 for driving the clamping block 20 to rotate. The support base 18 and the clamping block 20 are respectively provided with a first limiting groove 22 and a second limiting groove 23. The first limiting groove 22 and the second limiting groove 23 are respectively adapted to the shape and size of the pull rod to be processed. The controller 15 is electrically connected to the fourth hydraulic cylinder 19 and the third rotary motor 21.

[0018] After the first clamping rod 9 and the second clamping rod 10 clamp the two ends of the pull rod respectively, the first clamping plate 3 and the second clamping plate 4 are reset. At the same time, the controller 15 controls the fourth hydraulic cylinder 19 to drive the support base 18 to move vertically downward, so that the pull rod can be rotated more easily. When the pull rod is adjusted to the correct position, the controller 15 controls the fourth hydraulic cylinder 19 to drive the support base 18 to move vertically upward. At the same time, the controller 15 controls the third rotary motor 21 to drive the clamping block 20 to rotate a certain angle, so that the clamping block 20 and the support base 18 clamp the upper and lower sides of the pull rod simultaneously. This facilitates subsequent drilling work, ensures the positional stability of the pull rod during drilling, and thus improves the product qualification rate. The inner walls of the first limiting groove 22 and the second limiting groove 23 are provided with a first rubber pad 24 and a second rubber pad 25, which are adapted to the shape and size of the first limiting groove 22 and the second limiting groove 23 respectively.

[0019] Since the inner walls of the first limiting groove 22 and the second limiting groove 23 are provided with a first rubber pad 24 and a second rubber pad 25, the rubber pads have good shock absorption and anti-slip properties, which can further improve the positional stability of the pull rod during the drilling process, thereby improving the drilling accuracy and the product qualification rate.
