Description

Technical Field

[0001] This utility model relates to the field of electric drill gearbox assembly technology, specifically to a torsion spring assembly mechanism. Background Technology

[0002] The torsion spring in the gearbox of an electric drill is a key component for transmitting torque and buffering impact. The quality of its assembly with the spring seat directly affects the service life, output torque stability, and safety performance of the electric drill.

[0003] The assembly of traditional torsion springs and spring seats mainly relies on manual operation, which has the following significant problems: Torsion springs are small in size and highly elastic, and are prone to deformation or bouncing when manually handled, making assembly difficult. The spring seat and spring require high precision in their fit. It is difficult to control the force and angle when manually pressing them together, which can easily lead to defects such as uneven pressing, missing parts, or spring twisting. Manual inspection relies on visual inspection and simple tools (such as calipers), which are highly subjective and have a high rate of missed detections. With rising labor costs, the unit cost of manual assembly is increasing year by year; Therefore, a torsion spring assembly mechanism is needed to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a torsion spring assembly mechanism to solve the problems mentioned in the background art, which are that the assembly of traditional torsion springs and spring seats mainly relies on manual operation, resulting in the following problems: low efficiency and poor consistency of manual assembly, insufficient reliability of manual inspection, high quality risk, high labor intensity and high production cost.

[0005] This utility model provides the following technical solution: a torsion spring assembly mechanism, including an assembly mechanism, wherein the assembly mechanism includes a turntable driven by a servo motor and having a material placement groove on its surface, and the material placement groove of the turntable is used by a mechanical gripper to sequentially place the spring and the spring seat; In addition, there are pressing fixtures distributed around the turntable for pressing and fixing the springs and spring seats, and material handling fixtures for removing the finished springs. The material handling fixture separates the good products and defective products into different areas. An assembly fixture is set outside the good product area to assemble the good products onto the products on the conveyor line. It also includes a feeding mechanism that supplies materials to the turntable.

[0006] To achieve the above technical solution, a turntable is used to drive the material trough to adjust its position. In conjunction with the pressing tool and the material picking tool on the outside of the turntable, the spring is pressed into the spring seat and then taken out, forming continuous production. Compared with the existing technology, the operation process of this device is faster, the overall efficiency is higher, and the overall assembly is less prone to errors and has better stability.

[0007] As a further improvement to this utility model, a positioning fixture driven by a servo motor is also provided around the turntable to adjust the position of the spring seat.

[0008] Implementing the above technical solution facilitates adjusting the initial orientation of the spring seat.

[0009] As a further improvement to this utility model, a testing fixture is also provided around the turntable to test the finished spring after it has been compressed.

[0010] The above technical solution aims to prevent defective products from being packaged into the final product.

[0011] As a further improvement to this utility model, the number of material placement slots on the turntable corresponds to the number and position of the surrounding tooling, and is symmetrical along the center of the turntable, so that any material placement slot is cyclically passed through the adjustment tooling, pressing tooling, detection tooling and material picking tooling.

[0012] The above technical solutions will improve overall production efficiency.

[0013] As a further improvement to this utility model, the feeding mechanism includes a first vibrating feeding plate that feeds the adjusting tooling with a spring seat.

[0024] Example: Referring to the accompanying drawings, this utility model provides a torsion spring assembly mechanism, which is used to automate the assembly of the spring and the spring seat, as well as the assembly of the finished product. Its core structure and working process are as follows: In assembly mechanism 100: The turntable 110 has four material slots evenly distributed along the circumference (slot depth 15-20mm, diameter 0.5-1mm larger than the spring seat), which are driven by a servo motor to achieve intermittent rotation (rotation angle 90° / station). The adjustment fixture 115 is located at the first station of the turntable 110, including an adjustment seat driven by a servo motor (with a positioning groove on the surface that matches the spring seat), which, together with a photoelectric sensor, captures the direction of the spring seat and rotates and positions it to a specified angle. The pressing fixture 111 is located at the second station of the turntable 110. The pressing head is driven by the pressing head cylinder to press the spring into the spring seat (pressing depth 10-15mm to ensure that the spring is fully inserted into the slot). Inspection fixture 112 is located at the third station of turntable 110. It uses a laser displacement sensor to detect the spring assembly height. If the height is within the set range, it is judged as a good product; otherwise, it is a defective product. The material handling fixture 113 is located at the fourth station of the turntable 110. It includes a pneumatic gripper and a translational pusher cylinder. Based on the test results, it distributes the finished springs to the good product area or the defective product area.

[0025] In the material supply mechanism 200: The first vibrating feeder 210 is used for feeding spring seats. Vibration oriented the spring seats (face up). A material separating mechanism is set at the end of the feeding track (separates 1 spring seat at a time). The second vibrating feeding plate 211 conveys springs, and the material distribution component 212 uses a cylinder to push the baffle plate to separate individual springs, ensuring precise docking with the spring seat.

[0026] In the assembly mechanism: Assembly fixture 114 includes a rotary cylinder and a lifting cylinder (stroke 100-150mm), with a pneumatic gripper at the end (fitted to the shape of the spring seat). After grabbing the finished spring from the good product area, it rotates 180°, descends, and fits into the assembly shaft of product 333.

[0027] Assembly process Spring seat feeding and adjustment: The first vibrating feeder 210 conveys the spring seat to the front end. The mechanical gripper (pneumatic gripper, which descends by a cylinder and moves by a push cylinder) descends, grabs and transfers the spring seat to the adjustment fixture 115. After the adjustment fixture 115 is rotated and positioned, the mechanical gripper places the spring seat into the material trough of the turntable 110 (empty material troughs are cyclically fed in).

[0028] Spring press fitting Turntable 110 rotates 90°, carrying the spring seat to below the pressing fixture 111. The second vibrating feeding plate 211 feeds the material, and the material distribution component 212 separates a single spring. The mechanical gripper puts the spring into the spring seat. The pressing head cylinder of the pressing fixture 111 is activated, and the pressing head descends to press the spring into the spring seat. After the spring is formed into a finished product, the pressing head is reset.

[0029] Detection and material distribution Turntable 110 continues to rotate 90°, and the finished spring is moved to the inspection fixture 112, where the laser sensor detects the assembly height. Turntable 110 rotates another 90°, and tooling 113 picks up the finished spring and distributes it to the good / defective product area according to the test results.

[0030] Finished product assembly to product The assembly tool 114 lowers the lifting cylinder to grab the finished spring from the good product area. After the cylinder resets and the rotating cylinder rotates 180°, the lifting cylinder then lowers to fit it into the assembly position of product 333, completing the final assembly.
