Description

Technical Field

[0001] This utility model relates to the field of refrigerator handle processing technology, and in particular to a drilling and positioning device for refrigerator handle processing. Background Technology

[0002] With the improvement of living standards, refrigerators are widely used in homes and businesses. Refrigerators include refrigerator handles. Due to the structural characteristics of refrigerators, holes need to be drilled at both ends of the refrigerator handle during the manufacturing process.

[0003] When drilling holes for refrigerator handles, it is necessary to position them first. Since the length of the handles produced may vary, adjusting their positioning can be inconvenient and the positioning operation is relatively cumbersome, resulting in low processing efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a drilling and positioning device for processing refrigerator handles, thereby solving the problems mentioned in the background section.

[0005] A drilling and positioning device for processing refrigerator handles includes a base and a positioning mechanism mounted on the base. The positioning mechanism includes guide rails, a placement platform, a first limiting part, an electric cylinder, a telescopic part, a dual-axis motor, a lead screw, a second limiting part, a locking bolt, and a sliding seat. Two guide rails are respectively installed on support platforms on both sides of the upper surface of the base. The placement platform is fixedly installed in the middle of the base. The first limiting part slides along a groove on the placement platform and extends to the other side of the placement platform, where it is fixedly connected to the output end of the electric cylinder. The telescopic parts are installed opposite each other on both sides of the first limiting part. The dual-axis motor is located below the first limiting part. The lead screw is installed opposite each other at the output ends on both sides of the dual-axis motor. The sliding seat is rotatably mounted on the end of the lead screw and slides along the guide rails. Two second limiting parts are respectively connected to a corresponding lead screw and fixedly connected to a corresponding telescopic part. The locking bolt is rotatably mounted on the upper end of the second limiting part.

[0006] By adopting the above technical solution, it is convenient to place the refrigerator handle, so that the position of the refrigerator handle to be drilled is facing upwards, and the refrigerator handles of different sizes can be positioned and clamped.

[0007] The limiting part is arranged in an L-shape. The telescopic part is fixed on both sides of the short end of the limiting part. The output end of the electric cylinder is fixedly connected to the long end of the limiting part through a connecting plate. The bottom of the limiting part slides along the slide groove through a slider. The dual-axis motor is mounted on the bottom of the slider through a mounting base.

[0008] By adopting the above technical solution, it is possible to clamp and position the refrigerator handle.

[0009] The second limiting part is L-shaped, with its long end fixedly connected to the telescopic part. The side of the long end that fits against the handle and the side of the short end of the limiting part that fits against the handle are on the same vertical section. The locking bolt is rotatably installed at the short end of the second limiting part.

[0010] By adopting the above technical solution, it is possible to adjust the length according to the length of the refrigerator handle.

[0011] The sliding seat consists of a slider and a rotating shaft. The rotating shaft is rotatably connected to the slider, the slider slides along the guide rail, and the rotating shaft is fixedly connected to the lead screw.

[0012] By adopting the above technical solution, it is possible to make adjustments and clamp and position the refrigerator handle.

[0013] The upper end of the limiting part is provided with a right-angle step, which is used to fit the handle at the right angle of the limiting part.

[0014] By adopting the above technical solution, the refrigerator handle is placed in the corresponding position, which facilitates subsequent clamping and positioning.

[0015] The beneficial effects of this utility model's drilling and positioning device for refrigerator handle processing are:

[0016] The handle is pressed and limited by the first and second limiting parts together, and the short end of the second limiting part can fit against the inner side of the handle's side arm. The locking bolt can restrict the handle's freedom of upward movement, thereby stabilizing and limiting the handle, making it convenient to place the refrigerator handle, positioning the position of the refrigerator handle to be drilled upward, and positioning and clamping refrigerator handles of different sizes.

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0021] Reference Figure 1-2 A drilling and positioning device for processing refrigerator handles includes a base 1 and a positioning mechanism mounted on the base 1. The positioning mechanism includes a guide rail 2, a placement platform 3, a first limiting part 4, an electric cylinder 5, a telescopic part 6, a dual-axis motor 7, a lead screw 8, a second limiting part 9, a locking bolt 10, and a sliding seat 11. There are two guide rails 2, which are respectively installed on the support platforms on both sides of the upper surface of the base 1. The placement platform 3 is fixedly installed in the middle of the base 1. The first limiting part 4 slides along the slide groove 301 of the placement platform 3 and passes through... The other side of the placement platform 3 is fixedly connected to the output end of the electric cylinder 5. The telescopic part 6 is installed opposite to both sides of the limiting part 4. The dual-axis motor 7 is set below the limiting part 4. The lead screw 8 is installed opposite to both sides of the output end of the dual-axis motor 7. The sliding seat 11 is rotatably installed on the end of the lead screw 8 and slides along the guide rail 2. There are two limiting parts 9, which are respectively connected to the corresponding lead screw 8 and fixedly connected to the corresponding telescopic part 6. The locking bolt 10 is rotatably installed on the upper end of the limiting part 9.

[0022] The handle 12 can be placed at the corner of the upper end of the platform 3. The electric cylinder 5 is driven to move the limiting part 4 (at this time, the limiting part 4 does not need to be attached to the handle 12) so that the upper end of the limiting part 9 is moved above the handle 12. The dual-axis motor 7 is then driven to move the limiting part 9 in the opposite direction through the lead screw 8 until the two limiting parts 9 are attached to the two sides of the handle 12 for internal support. Then the electric cylinder 5 is driven to pull the limiting part 4 to apply pressure to the middle of the handle 12 and rotate the locking bolt 10 downward to restrict the handle 12, thus completing the restriction of the handle 12.

[0023] When the electric cylinder 5 pulls the limiting part 4 to move, the dual-axis motor 7 moves synchronously, while the sliding seat 11 moves along the guide rail 2 driven by the lead screw 8, and the lead screw 8 drives the limiting part 9 to move synchronously, thereby adjusting and positioning according to the size of the handle 12.

[0024] The limiting part 4 is arranged in an L-shape. The telescopic part 6 is fixed on both sides of the short end of the limiting part 4. The output end of the electric cylinder 5 is fixedly connected to the long end of the limiting part 4 through a connecting plate. The bottom of the limiting part 4 slides along the slide groove 301 through a slider. The dual-axis motor 7 is mounted on the bottom of the slider through a mounting base so that when the electric cylinder 5 moves the limiting part 4, the dual-axis motor 7 can move synchronously. The upper end of the limiting part 9 is fixedly connected to the limiting part 4 through the telescopic part 6, thereby ensuring that the limiting part 9 can move synchronously.

[0025] The limiting part 2 9 is L-shaped, with its long end fixedly connected to the telescopic part 6. The side of the long end that fits against the handle 12 and the side of the short end of the limiting part 1 4 that fits against the handle 12 are on the same vertical section. The locking bolt 10 is rotatably installed at the short end of the limiting part 2 9. The limiting part 1 4 and the limiting part 2 9 together apply pressure to limit the handle 12, and the short end of the limiting part 2 9 can fit against the inner side of the side arm of the handle 12, thereby stably limiting the handle 12.

[0026] The sliding seat 11 consists of a slider and a rotating shaft. The rotating shaft is rotatably connected to the slider, and the slider slides along the guide rail 2. The rotating shaft is fixedly connected to the lead screw 8. The sliding seat 11 can move synchronously with the lead screw 8 while adjusting the position of the dual-axis motor 7, so as to facilitate the positioning of the handle 12.

[0027] The upper end of the limiting part 14 is provided with a right-angle step, which is used to fit the handle 12 against the right angle of the limiting part 14; thus, together with the limiting part 14 and the limiting part 29, the handle 12 is fixed on the placement platform 3, while the locking bolt 10 can restrict the degree of freedom of the handle 12 to move upward.

[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
