Description

Technical Field

[0001] The utility model mainly relates to the technical field of plastic grinding, and in particular to a mobile chassis hole burr cleaning device. Background Art

[0002] Household appliances such as washing machines are equipped with mobile chassis made of injection molded parts. After the injection molded parts are completed, the burrs on the holes of the chassis made of the injection molded parts need to be cleaned.

[0003] In the current deburring process of injection molded parts, workers are required to use a handheld electric grinder or a trimming knife to perform the deburring operation. The handheld electric grinder is heavy, and workers need to hold the handheld electric grinder for a long time during the deburring operation of the holes in the mobile chassis, which consumes a lot of physical energy of the workers.

[0004] The inventor proposed a mobile chassis hole burr cleaning device. By setting a telescopic structure, a handheld electric grinder is assembled on a bracket at the moving end of the telescopic structure. The worker operates the rubber-coated grip on the bracket to prevent the vibration generated by the handheld electric grinder from being directly transmitted to the worker's hands. During the grinding operation, the worker only needs to press the injection molded part on the workbench with one hand and operate the rubber-coated grip with the other hand to complete the grinding operation.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0038] See attached Figure 1-4 The utility model provides a mobile chassis hole burr cleaning device, comprising the following structure:

[0039] The workbench 1 has a positioning tube 2 fixedly disposed on the top surface thereof, and a shaft sleeve 3 is sleeved on the outer side of the positioning tube 2 .

[0040] The first connecting rod 4 has a connecting shaft 5 movably connected to its bottom, a second connecting rod 6 movably connected to its top, a bracket 7 movably connected to its bottom, and an electric grinder 8 fixedly disposed on the outer side of the bracket 7.

[0041] In this embodiment, Figure 1 and Figure 2 As shown, an aluminum profile frame 11 is fixedly provided at the bottom of the workbench 1 , a slide 12 is slidably connected to the outer side of the aluminum profile frame 11 , and a collection box 13 is clamped to the outer side of the slide 12 .

[0042] The slide 12 and the collection box 13 cooperate, and the user can adjust the working position of the collection box 13 outside the workbench 1 as needed, so that the user can clean the plastic debris and other debris generated by the deburring operation on the workbench 1 into the collection box 13 to keep the workbench 1 clean and tidy.

[0043] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the surface of the positioning tube 2 is fixed with positioning holes at equal intervals from bottom to top, the surface of the positioning tube 2 is plugged with a positioning pin 21, and the outer side of the positioning tube 2 is movably sleeved with the middle part of the shaft sleeve 3.

[0044] The positioning hole and the positioning pin 21 cooperate to complete the installation height adjustment of the sleeve 3 on the positioning tube 2. The structural design is simple and convenient to use, wherein the positioning pin 21 provides support for the sleeve 3.

[0045] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the bottom of the sleeve 3 abuts against the outer side of the limiting pin, and limiting frames 31 are fixedly provided on the top and bottom of the sleeve 3.

[0046] The arrangement of the shaft sleeve 3 and the limiting frame 31 cooperates with the leaf spring 51 on the connecting shaft 5 to prevent the first connecting rod 4 from falling directly onto the working platform 1 due to lack of limiting.

[0047] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the left and right ends of the connecting shaft 5 are movably connected to the inner sides of the left and right ends of the sleeve 3 respectively, and leaf springs 51 are fixed on both sides of the connecting shaft 5, and the rear end of the leaf spring 51 extends between the opposite sides of the two limit frames 31.

[0048] The connecting shaft 5 completes the assembly of the first connecting rod 4 outside the sleeve 3. The leaf spring 51 is designed and used. After the user comes into contact with the device, the leaf spring 51 cooperates with the rotating shaft to drive the first connecting rod 4 to deflect upward on the outside of the sleeve 3.

[0049] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a return spring 61 is clamped on the top of the second connecting rod 6 , and the bottom of the return spring 61 is clamped on the outer side of the limiting frame 31 on the top of the shaft sleeve 3 .

[0050] When the user is not in contact with the device, the return spring 61 cooperates with the second connecting rod 6 to pull the second connecting rod 6 at the top of the first connecting rod 4 and deflect it counterclockwise to complete the lifting of the bracket 7, thereby preventing the grinding head of the electric grinder 8 from colliding with the surface of the workbench 1 and damaging the workbench 1.

[0051] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the left side and the front of the bracket 7 are fixedly connected to the bottom and the top of the rubber-coated gripping rod 71 respectively, and the first clamping seat 72 and the second clamping seat 73 are fixedly provided on the bottom left side and the front side of the bracket 7 respectively, and the middle parts of the first clamping seat 72 and the second clamping seat 73 are fixedly provided with a straight-line laser indicator 74, and the two straight-line laser indicators 74 and the axis line connecting the output shaft of the electric grinder 8 are perpendicular to each other.

[0052] The design of the rubber-coated grip 71 and the bracket 7 allows the worker to operate the rubber-coated grip 71 on the bracket 7 to avoid the vibration generated by the handheld electric grinder 8 being directly transmitted to the worker's hands. During the grinding process, the worker only needs to press the injection molded part on the table top of the workbench 1 with one hand, and operate the rubber-coated grip 71 with the other hand to complete the grinding operation. The worker's hands do not need to bear the weight of the electric grinder 8, thereby reducing the worker's labor load.

[0053] When the straight-line laser pointer 74 on the first clamping seat 72 and the second clamping seat 73 is irradiated onto the injection-molded part of the mobile chassis or the table top of the workbench 1, the vertical intersection of the two laser indicator lines is the axial direction of the output shaft of the electric grinder 8, which assists workers in determining the specific position of the grinding head above the mobile chassis and facilitates workers to adjust the working position of the electric grinder 8 through the rubber-coated grip 71 to deburr the holes of the mobile chassis, thereby improving the convenience of the deburring operation of the mobile chassis.

[0054] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
