Abstract
Description
Technical Field
[0001] This utility model relates to the field of automatic bolt tightening technology in the automotive industry, and in particular to a vertical and horizontal dual-purpose tightening device. Background Technology
[0002] An engine is made up of hundreds or thousands of parts that are organically connected in a certain way and according to certain requirements to form an engine assembly. During the assembly process, the most common assembly method that operators encounter is threaded connection.
[0003] Threaded connections are one of the four common connection methods between engine components (threaded connections, welding, riveting, and adhesive bonding), accounting for approximately 70% of engine connections. They offer advantages such as high precision, convenient assembly, and easy disassembly and assembly of parts. Therefore, the reliability of threaded connections is crucial and important for ensuring engine quality. For example, in connecting rod bolt connections, insufficient torque can lead to engine bearing noise at best, and at worst, the nut loosening, causing connecting rod breakage and serious engine damage.
[0004] Traditional engine assembly threaded connections require manual tightening of bolts one by one, which presents technical problems such as the inability to tighten multiple bolts simultaneously, low precision, and uneven torque. Furthermore, traditional tightening methods are labor-intensive and noisy.
[0005] Therefore, researching electric tightening technology is of great significance for ensuring the assembly quality of engines. Utility Model Content
[0006] This utility model mainly solves the technical problems of traditional engine assembly threaded connections, which require manual tightening of bolts one by one, resulting in multiple bolts not being able to be tightened simultaneously, low precision, and uneven torque. It proposes a vertical and horizontal dual-purpose tightening device with angle adjustment to adapt to tightening bolts at both horizontal (horizontal) and vertical (vertical) angles, thereby improving the product's adaptability.
[0007] This utility model provides a vertical and horizontal dual-purpose tightening device, including: a frame, an outer housing, an inner housing, and at least one tightening shaft;
[0008] The frame includes: a suspension rod and support plates disposed at both ends of the suspension rod; an arc-shaped slide rail is provided on the support plate;
[0009] Rotating shafts are respectively provided on both sides of the outer casing; the rotating shafts are hinged to the support plate;
[0010] A locking bolt is provided on one side of the outer casing. The locking bolt passes through an arc-shaped slide rail, and a locking handwheel is provided at the outer end of the locking bolt.
[0011] An inner box is rotatably disposed within the outer box; the bottom end of the inner box passes through the lower plate of the outer box.
[0012] At least one tightening shaft is provided inside the inner box, and a tightening sleeve is provided at the output end of the tightening shaft.
[0013] Preferably, a suspension seat is provided on the suspension rod.
[0014] Preferably, four support rods are provided between the upper and lower plates of the outer casing.
[0015] Preferably, a round handle is provided at the bottom end of the inner box.

[0027] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.
[0028] like Figure 1-3 As shown in the figure, the present invention provides a vertical and horizontal dual-purpose tightening device, including: a frame, an outer housing 14, an inner housing 15, and at least one tightening shaft 7.
[0029] The frame includes: a suspension rod 2 and support plates 3 disposed at both ends of the suspension rod 2; the suspension rod 2 and the two support plates 3 are connected to form the frame by bolts. A suspension seat 1 is provided on the suspension rod 2 to facilitate the fixing of the frame. An arc-shaped slide rail 4 is provided on the support plate 3 to facilitate guidance during rotation and adjustment.
[0030] The outer casing 14 has rotating shafts 6 on both sides; the rotating shafts 6 are hinged to the support plate 3; a locking bolt 13 is provided on one side of the outer casing 14, the locking bolt 13 passes through the arc-shaped slide rail 4, and a locking handwheel 10 is provided at the outer end of the locking bolt 13. Tightening the locking handwheel 10 can lock the outer casing 14. When the outer casing 14 rotates, the rotating shaft 6 acts as a fulcrum, and the locking bolt 13 and locking handwheel 10 can lock the outer casing 14 at different positions on the arc-shaped slide rail 4. When the outer casing 14 is locked at the highest point of the arc-shaped slide rail 4, the outer casing 14 is used vertically (vertical); when the outer casing 14 is locked at the lowest point of the arc-shaped slide rail 4, the outer casing 14 is used horizontally (horizontal).
[0031] An inner box 15 is rotatably mounted inside the outer box 14. Specifically, the top of the inner box 15 is connected to the upper plate 5 of the outer box 14 via a bearing; the bottom of the inner box 15 passes through the lower plate 9 of the outer box 14, and the bottom of the inner box 15 is connected to the lower plate 9 via a bearing to facilitate the rotation of the inner box 15. Four support rods 8 are provided between the upper plate 5 and the lower plate 9 of the outer box 14 to reinforce the outer box 14.
[0032] At least one tightening shaft 7 is provided inside the inner housing 15, and a tightening sleeve 12 is provided at the output end of the tightening shaft 7. In this invention, two tightening shafts 7 are provided. The tightening shafts 7 are electric tightening shafts. An electric tightening shaft is a precision tool used in automated assembly lines, mainly for tightening fasteners such as screws and bolts. The electric tightening shaft can automatically rotate and tighten bolts and can precisely control the tightening torque. An electric tightening shaft typically includes: a motor, a planetary gear reducer, a torque sensor, and an output shaft; the torque sensor is connected to the tightening sleeve 12 via the output shaft.
[0033] A round handle 11 is provided at the bottom of the inner box 15. Rotating the round handle 11 can rotate the inner box 15 and the tightening shaft 1, thereby realizing the circumferential rotation adjustment of the tightening shaft 1.
[0034] The working principle of this utility model is as follows: The outer housing 14 is hinged to the frame via two left and right rotating shafts 6. The outer housing 14 can rotate along the arc-shaped slide rail 4, driving the inner housing 15 and its tightening shaft 7 to rotate, achieving both horizontal and vertical angle operation. During manual operation, the angle of the tightening shaft 7 is adjusted according to the angle of the workpiece (bolt) to be tightened. Figure 1-3 The image shows the vertical usage configuration. Figure 4-5 The diagram shows the horizontal use state. The outer housing 14 is locked in place by locking the handwheel 10 to fix the use angle. The position of the tightening shaft 7 is adjusted according to the work position, and the tightening sleeve 12 is put into the bolt to start tightening the bolt. Once the tightening torque is reached, the tightening work is completed in one go.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions for some or all of the technical features, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
