Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone shell processing jig design, in particular to a positioning jig for mobile phone shell processing. Background Art

[0002] Mobile phone case processing jigs are auxiliary tools used in the manufacturing process of mobile phone cases. They play an important role in improving production efficiency, ensuring product quality and reducing production costs. For example, spraying jigs, welding jigs and pressure-maintaining jigs, etc., all of these processing jigs need to use positioning mechanisms when they are in use to ensure that the mobile phone case maintains sufficient stability during the processing, thereby ensuring stable and efficient work.

[0003] Currently, the positioning mechanisms used in the mobile phone shell processing jigs on the market are mostly driven by multiple electric devices. For example, patent No. CN218613006U discloses an adjustable positioning jig for processing mobile phone shells. By opening the cylinder, the cylinder can drive the clamp to move to clamp the mobile phone shell, and the mobile phone shell can be processed and positioned according to the needs.

[0004] This clamping mechanism is relatively convenient and fast to use, and has certain advantages when processing shells of different specifications in batches. However, it still has certain shortcomings. When producing shells of specific mobile phones of the same model, due to the large batch size and the same specifications, there is no need to adjust the clamping range. At this time, its shortcomings are more obvious. First, it is not easy to control the force through the cylinder control, and operating errors can easily cause damage to the workpiece, especially when frequent adjustments are required. Mistakes are more likely to occur. Secondly, multiple cylinder drives consume a lot of electricity, which greatly increases production costs. In addition, the cylinders are frequently used and require frequent maintenance and repairs, which is also very troublesome. At the same time, each cylinder is driven separately, and the clamping cannot be completed in one step.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a positioning fixture for processing a mobile phone shell is proposed. Utility Model Content

[0023] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0024] like Figure 1-Figure 6As shown, it includes a base 1, and a jig table 2 is installed on the top surface of the base 1 through four support rods. A shell body 3 is placed on the top surface of the jig table 2, and a positioning mechanism 4 is installed between the jig table 2 and the base 1. The positioning mechanism 4 includes a screw rod 41 rotating between the base 1 and the jig table 2, and the external thread of the screw rod 41 is connected to a lifting block 42, and the four sides of the lifting block 42 are rotatably connected to a driving rod 43. The top of the driving rod 43 is hinged at the bottom of a moving slider 44, and the moving slider 44 slides in the slideway inside the jig table 2. The vertical rod 45 on the top of the moving slider 44 passes through the jig table 2 and is installed with an L-shaped clamping plate 46, and the L-shaped clamping plate 46 is in contact with the outer wall of the shell body 3.

[0025] By designing the positioning mechanism 4, when clamping and positioning, the shell body 3 is placed at a suitable position on the top surface of the fixture table 2. At this time, the screw rod 41 is manually rotated to make the lifting block 42 descend, the connecting part of the driving rod 43 and the lifting block 42 rotates, and a pulling force is applied to the moving slider 44, so that the moving slider 44 slides in the slideway, and the four driving rods 43 are driven at the same time, so that the four vertical rods 45 drive the L-shaped clamping plate 46 together toward the direction of the shell body 3, and finally complete the clamping. In this way, the clamping is very simple and fast, and the clamping operation can be completed in one step, and the efficiency is very high. It should be noted that the connecting part of the moving slider 44 and the driving rod 43 and the vertical rod 45 all slide in the opening of the slideway connected to the fixture table 2. This is an existing design method and will not be repeated here.

[0026] Two sliding rods 49 are inserted and slidably connected at the top of the L-shaped clamping plate 46, and a top pressure plate 411 is installed at the bottom of the sliding rod 49. The top pressure plate 411 is in contact with the top surface of the shell body 3, and a spring 410 is connected to the top of the sliding rod 49 and the top surface of the L-shaped clamping plate 46. The bottom surface of one side of the top pressure plate 411 is designed as an arc surface, and the arc surface is located at the end of the top pressure plate 411 close to the shell body 3. A socket 48 is fixed on the back of the L-shaped clamping plate 46, and the socket 48 is sleeved on the outside of the vertical rod 45 and fixed with screws. An anti-slip knob 47 is fixed to the outer wall of the screw rod 41, and the anti-slip knob 47 is close to the top surface of the seat 1.

[0027] In further optimization of the positioning mechanism 4, when the L-shaped clamp 46 presses against the side of the shell body 3, one side of the top pressure plate 411 will also contact the upper corner of one side of the shell body 3. Since the contact surface between the top pressure plate 411 and the shell body 3 is an arc surface design, the top pressure plate 411 moves upward until the horizontal part of the bottom of the top pressure plate 411 contacts the top surface of the shell body 3. At this time, the slide rod 49 will also move upward and stretch the spring 410, thereby making the top pressure plate 411 press the top surface of the shell body 3 well, further enhancing the positioning effect, and the design of the sleeve 48 makes it easy to disassemble the L-shaped clamp 46 for maintenance, which is very convenient.

[0028] The jig table 2 is composed of an upper base 21 and a lower base 22, which are attached to each other and fixed with bolts, and the upper base 21 and the lower base 22 divide the jig table 2 into two equal parts, the lower base 22 is located at the bottom and connected to the base 1 through a support rod, and the lower base 22 is rotatably connected to the top of the screw rod 41, the upper base 21 is located at the top and the outer shell body 3 is placed thereon, and a limit block 5 is installed on the top of the upper base 21, the limit blocks 5 are evenly distributed on the four sides of the outer shell body 3, and two limit blocks 5 are provided on each side of the outer shell body 3, the limit blocks 5 are close to the outer shell body 3, and the limit blocks 5 on each side are located on both sides of the L-shaped clamp 46.

[0029] In the optimized design of the jig table 2, dust is easily accumulated inside the slideway where the movable slider 44 slides during use. Therefore, a splicing design is adopted to divide the upper seat 21 and the lower seat 22 into two parts for cleaning, which is very convenient. The limit block 5 can play an initial positioning role to facilitate placement.

[0030] Working principle: When working, first install the base 1 on a suitable processing table, spraying and welding are both possible, then cover the upper base 21 on the top surface of the lower base 22 and fix it, when clamping and positioning, place the shell body 3 on the inner side of the limit block 5 on the top surface of the fixture table 2 for initial positioning, at this time manually rotate the screw rod 41 to make the lifting block 42 descend, the connecting part of the driving rod 43 and the lifting block 42 rotates, and applies tension to the moving slider 44, so that the moving slider 44 slides in the slideway, and the four driving rods 43 are driven at the same time, so that the four vertical rods 45 drive the L-shaped clamping plate 46 to fit with the shell body 3 in the direction of the shell body 3, and at the same time, one side of the top pressure plate 411 will also contact the upper corner of one side of the shell body 3, so that the top pressure plate 411 moves up until the horizontal part of the bottom of the top pressure plate 411 contacts the top surface of the shell body 3, which can well press the top surface of the shell body 3, thereby completing the positioning operation, and then it is well used for the processing of mobile phone shells with the same specifications as the batch.
