Description

Technical Field

[0001] This invention relates to the field of mold manufacturing technology, and specifically to a nut-driving device. Background Technology

[0002] A mold is a tool used to create shaped objects. This tool consists of various parts, and different molds are composed of different parts. It primarily achieves the shaping of objects by altering the physical state of the material being molded.

[0003] Mold parts are typically connected using bolts, and the outer diameter of the bolts varies depending on the size of the part. Some mold parts are very small, and the outer diameter of the connecting bolts used is only 1.2-1.6mm. After the bolts are installed, it is difficult for the operator to install the matching nuts onto them. How to provide a device that can effectively install the nuts is a problem we need to study. Summary of the Invention

[0004] The purpose of this invention is to provide a nut-driving device to solve the problems caused by the prior art.

[0005] To achieve the above objectives, the present invention is implemented using the following technical solution:

[0006] A nut-driving device includes a base plate, and positioning guide posts for matching mold connection holes are connected to both sides of the top surface of the base plate.

[0007] A mounting plate is connected to the top surface of the base plate, a first cylinder is fixedly connected to the bottom surface of the mounting plate, a slide rail is fixed to the top surface of the mounting plate, a cylinder connecting plate is connected to one end of the slide rail, the bottom end of the cylinder connecting plate is connected to the output end of the first cylinder, a second cylinder is connected to the top surface of the cylinder connecting plate, a slide block is connected to the other end of the slide rail, an outer rod sleeve is connected to the slide block, an inner support rod is slidably connected inside the outer rod sleeve, the inner support rod is connected to the cylinder connecting plate through a connecting slide block seat, and the inner support rod is connected to the second cylinder through a connecting head.

[0008] The end of the outer sleeve is provided with a mounting hole for installing a nut.

[0009] Furthermore, the slide block is provided with an air hole, which is connected to the connecting inner hole inside the outer sleeve rod. The mounting hole is connected to the connecting inner hole, and the inner diameter of the mounting hole is larger than the inner diameter of the connecting inner hole.

[0010] Furthermore, a quincunx hole is provided between the connecting inner hole and the mounting hole.

[0011] Furthermore, the mounting plate and the base plate are connected by a support frame.

[0012] Furthermore, there are two positioning guide posts, and each of the two positioning guide posts is equipped with a magnet.

[0013] Furthermore, the top surfaces of the magnets on the two positioning guide posts are in the same horizontal plane.

[0014] Furthermore, it also includes a handle connecting plate, on which a handle is provided, and the handle connecting plate is connected to the base plate.

[0015] According to the above technical solution, the embodiments of the present invention have at least the following effects:

[0016] 1. When using the nut-installing device, the nut is placed in the mounting hole. The first cylinder drives the inner support rod and the outer sleeve to move simultaneously, so that the inner support rod contacts the bolt. Then, the second cylinder drives the outer sleeve to move, and the outer sleeve drives the nut to fit around the bolt to complete the installation. This device can effectively install nuts and solve the problem of difficulty in installing small-sized nuts.

[0017] 2. By setting a connecting inner hole on the outer rod and connecting it to the air hole, an air source can be connected to the air hole during use, which can effectively realize the suction and installation of nuts, improving the efficiency of nut suction and installation; the plum blossom hole set in this device can ensure the fixing effect of nuts in the installation hole and increase the suction effect of nuts.

[0018] 3. The positioning guide post of this device is compatible with the connecting hole on the mold, which ensures the connection effect of the positioning guide post. By setting a magnet on the positioning guide post, the magnet attracts the mold, ensuring that no manual hand is needed when tightening the nut, thus freeing up manpower. Attached Figure Description

[0026] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0027] It should be noted that in the description of this invention, the terms "front," "rear," "left," "right," "upper," "lower," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used only for the convenience of describing the invention and do not require the invention to be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on the invention. The terms "front," "rear," "left," "right," "upper," and "lower" used in the description of this invention refer to the directions shown in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0028] like Figures 1 to 6 As shown, a nut-driving device includes a base plate 1. Positioning guide posts 3, adapted to the mold connection holes, are connected to both sides of the top surface of the base plate 1. A mounting plate 5 is connected to the top surface of the base plate 1. A first cylinder 6 is fixedly connected to the bottom surface of the mounting plate 5. A slide rail 13 is fixed to the top surface of the mounting plate 5. One end of the slide rail 13 is connected to a cylinder connecting plate 71. The bottom end of the cylinder connecting plate 71 is connected to the output end of the first cylinder 6. A second cylinder 7 is connected to the top surface of the cylinder connecting plate 71. The other end of the slide rail 13 is connected to a slide block 10. An outer rod sleeve 12 is connected to the slide block 10. An inner support rod 11 is slidably connected inside the outer rod sleeve 12. The inner support rod 11 is connected to the cylinder connecting plate 71 via a connecting slide block seat 8. The inner support rod 11 is connected to the second cylinder 7 via a connector 9. An installation hole 123 for installing a nut is provided at the end of the outer rod sleeve 12.

[0029] When using the nut-installing device, the nut is placed in the mounting hole. The first cylinder drives the inner support rod 11 and the outer sleeve 12 to move simultaneously, so that the inner support rod 11 contacts the bolt. Then, the second cylinder drives the outer sleeve 12 to move, and the outer sleeve 12 drives the nut to fit around the bolt to complete the installation. This device can effectively install nuts and solve the problem of difficulty in installing small-sized nuts.

[0030] Specifically, such as Figure 1 As shown, the nut-installing device of this apparatus includes a base plate 1, which serves as the overall connection and support. A handle connecting plate 2 is connected to the left side of the base plate 1. The handle connecting plate 2 is L-shaped, with one end plate connected to the base plate 1 by screws, and the other end plate having a handle 21, which facilitates the operator to hold the device and install the nut.

[0031] like Figure 1 As shown, a support frame 4 is connected to the top surface of the base plate 1. There are two support frames 4, one in the front and one in the back. The two support frames 4 work together to connect the mounting plate 5. The end of the mounting plate 5 is also connected to the base plate 1 through a support rod 41, which ensures the stability of the mounting plate 5.

[0032] like Figure 2 As shown, a first cylinder 6 is fixedly connected to the bottom surface of the mounting plate 5, and the first cylinder 6 is arranged in the left-right direction. The top surface of the mounting plate 5 has a left-right mounting groove, in which a slide rail 13 is fixed. A cylinder connecting plate 71 is slidably connected to the left end of the slide rail 13, and the bottom end of the cylinder connecting plate 71 is connected to the output end of the first cylinder 6. The extension and retraction of the first cylinder 6 causes the cylinder connecting plate 71 to move left and right on the slide rail 13.

[0033] like Figure 2 As shown, a second cylinder 7 is fixed on the cylinder connecting plate 71, and a connecting slide head seat 8 is slidably connected to the slide rail 13, located on the left side of the cylinder connecting plate 71. A connector 9 is connected to the output end of the second cylinder 7, and the connector 9 is located inside the connecting slide head seat 8. A slide block 10 is slidably connected to the right end of the slide rail 13, and the left end of the slide block 10 is located inside the connecting slide head seat 8, connecting the slide block 10 and the connector 9. A baffle is provided inside the connecting slide head seat 8, and the connector 9 is located on the right side of the baffle. When the second cylinder 7 drives the connector 9 to move to the right, the connector 9 does not contact the baffle; when the second cylinder drives the connector 9 to move to the left, the connector 9 contacts the baffle.

[0034] During operation, the first cylinder 6 retracts, causing the cylinder connecting plate 71 to move to the right. The cylinder connecting plate 71 then causes the second cylinder 7 and the connecting slide block 8 to move to the right. The second cylinder 7, through the connecting head 9, causes the slide block 10 to move to the right. The first cylinder extends, causing the connecting slide block 8 and the slide block 10 to move to the left to reset. The second cylinder 7 extends, causing the connecting head 9 to move to the right, which in turn causes the slide block 10 to move to the right. The second cylinder retracts, causing the connecting slide block 8 and the slide block 10 to move to the left.

[0035] like Figure 2As shown, an outer rod sleeve 12 is fixedly connected to the slide block 10, and an inner support rod 11 is sleeved inside the outer rod sleeve 12. The left end of the inner support rod 11 is connected to the connecting slide block 8. In use, the first cylinder 6 drives the inner support rod 11 and the outer rod sleeve 12 to move together, so that the inner support rod 11 contacts the screw. Then, the second cylinder 7 drives the outer rod sleeve 12 to move to complete the installation of the nut.

[0036] like Figure 4 and Figure 5 As shown, the outer sleeve 12 has a mounting hole 123 at its end, which is used to place the nut and is sized to match the nut. The outer sleeve 12 has a connecting inner hole 121 at its central axis, which is connected to an air hole on the slide block 10. Air is supplied to the connecting inner hole 121 via an air source, creating negative pressure at the mounting hole 123 at the end to attract the nut. Installing the nut can also be accomplished by blowing air.

[0037] To ensure the adsorption effect of the nut, a plum blossom groove 122 is provided at the mounting hole 123 and the connecting inner hole 121. The plum blossom groove 122 serves two purposes: firstly, it limits the installation of the nut, and secondly, it increases the adsorption effect of the air source on the nut, thus ensuring the installation effect of the nut.

[0038] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
