Description

Technical Field

[0001] The utility model relates to the technical field of thin-wall plastic parts processing, in particular to an anti-deformation auxiliary fixture for thin-wall plastic parts processing. Background Art

[0002] Plastic parts refer to various parts made of plastic materials, which have the characteristics of light weight, short molding cycle, and high molding precision. They can be widely used in different fields such as home appliances, automobiles, electronics, and medical devices. Plastic parts are divided into injection molded parts, blow molded parts, extrusion molded parts, plastic injection molded parts, and plastic welded parts. At present, when processing special-shaped plastic parts, it is necessary to use a lathe to process them. During the turning process, due to the special shape of the plastic parts, the side walls of the plastic parts are thinner during processing. This will cause the plastic parts to deform or break during processing, which will increase the production failure rate of plastic parts. Therefore, it is necessary to provide an anti-deformation auxiliary fixture for processing thin-walled plastic parts to solve the above technical problems. Utility Model Content

[0003] The utility model aims to provide an anti-deformation auxiliary jig for processing thin-walled plastic parts, so as to solve the problems raised in the above-mentioned background technology.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

Installed on one side of the top of one of the sliders, a working motor is fixedly installed on one side of the top of the mounting frame, support frames are fixedly installed on the tops of the two sliders, one of the support frames is rotatably connected to a rotating seat at the top, and a fixed seat is fixedly installed on the top of the other support frame, the output end of the working motor is fixedly connected to one end of the synchronous pulley assembly, and the other end of the synchronous pulley assembly is fixedly connected to one end of the rotating seat, an auxiliary component is installed on one side of the rotating seat, and the end of the auxiliary component away from the rotating seat is fixedly connected to one side of the fixed seat, and a workpiece body is inserted between the auxiliary components.

[0006] A further improvement of the technical solution of the utility model is that: currently, when processing special-shaped plastic parts, it is necessary to use a lathe to process them. In the process of turning, due to the special shape of the plastic parts, the side walls of the plastic parts are thinner during processing.

[0008] A further improvement of the technical solution of the utility model is that the setting of the blocking soft plate can block the debris falling into the bottom plate, preventing the debris from accumulating inside the bottom plate and falling into the gap between the bottom plate and the slider, thereby affecting the movement stability of the slider, thereby ensuring the smooth operation of the device.

[0010] A further improvement of the technical solution of the utility model is that when the workpiece body needs to be processed, the workpiece body is clamped into the clamping seat, and then the distance between the sliders is adjusted to reduce the distance between the extrusion seat and the clamping seat, so that the workpiece body on the clamping seat is restricted by the extrusion seat, so as to increase the stability of the workpiece body during processing, and then the processing device is used to process the workpiece body. During the processing, air can be introduced into the interior of the fixed seat through the air inlet pipe, and blown to the workpiece body through the air outlet provided on the fixed seat, so as to clean the processing debris on the workpiece body.

[0011] The above technical solution is adopted, in which lightweight holes are opened on some of the limiting plates.

In addition, the limiting plate can view the workpiece body inserted into the base, increase the viewing area of ​​the workpiece body, and facilitate processing and use by the staff.

[0013] The above technical solution is adopted, and the outer ring of the card seat in this solution is provided with avoidance grooves at equal intervals.

[0014] A further improvement of the technical solution of the utility model is that the avoidance groove is set as a reserved groove for processing the workpiece body, which is convenient for processing the side wall of the workpiece body at the avoidance groove, and the place where the avoidance groove is not set on the holder can protect the workpiece body to avoid deformation of the workpiece body during the processing. The limiting plate can cooperate with the holder to better protect the workpiece body.

[0015] The above technical solution is adopted, in which one end of the fixing seat is sleeved with a mounting ring, the mounting ring is fixedly connected to the fixing seat by fastening bolts, and a protective net is fixedly installed on one end of the mounting ring away from the fixing seat.

[0031] In this embodiment, the staff drives the bidirectional screw 3 to rotate by turning the handwheel 4, and then adjusts the distance between the sliders 6, so that the workpiece body 14 to be processed is inserted into the interior of the auxiliary component. Subsequently, the bidirectional screw 3 adjusts the distance between the sliders 6 so that the auxiliary component can limit and clamp the workpiece body 14, and then the workpiece body 14 is processed by the lathe. Due to the setting of the auxiliary component, the workpiece body 14 can be protected to avoid deformation during the processing, avoid damage to the workpiece body 14 during the processing, and reduce the failure rate of the processing of the workpiece body 14.

[0032] like Figure 1 and Figure 2 As shown, based on Example 1, the utility model provides a technical solution: preferably, a blocking soft plate is provided between the two sliders 6.

[0033] In this embodiment, the setting of the blocking soft board can block the debris falling into the bottom plate 1, preventing the debris from accumulating inside the bottom plate 1 and falling into the gap between the bottom plate 1 and the slider 6, thereby affecting the movement stability of the slider 6, thereby ensuring the smooth operation of the device.

[0042] like Figure 3 As shown, based on Example 1, the utility model provides a technical solution: preferably, one end of the mounting ring 20 close to the fixing seat 15 is equidistantly provided with protrusions that are installed and matched with the fastening bolts 21.

[0043] In this embodiment, the protrusion at one end of the mounting ring 20 can increase the installation fit between the mounting ring 20 and the fixing seat 15 , thereby increasing the stability of the mounting ring 20 .

[0044] The following is a detailed description of the working principle of the anti-deformation auxiliary fixture for processing thin-walled plastic parts.

Then, by adjusting the spacing between the sliders 6, the spacing between the extrusion seat 12 and the holder 16 is reduced, so that the extrusion seat 12 restricts the workpiece body 14 on the holder 16, so as to increase the workpiece body 14 on the holder 16. The stability during processing is ensured, and then the processing device is used to process the workpiece body 14. During the processing, the wind can be introduced into the interior of the fixed seat 15 through the air inlet pipe 18, and blown to the workpiece body 14 through the air outlet 17 set on the fixed seat 15, so as to clean the processing debris on the workpiece body 14. The setting of the protective net 22 can prevent the production debris from clogging the air outlet 17, and can maintain the smoothness of the air outlet 17, thereby ensuring the operating stability of the device, and the setting of the mounting ring 20 can install the protective net 22.

[0046] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
