Description

Technical Field

[0001] The present application belongs to the technical field of lighting equipment manufacturing, and in particular relates to a lamp pole straightening device. Background Art

[0002] Streetlights typically consist of light poles and lighting components. The production process for light poles generally involves cutting, bending, welding, repairing, polishing, shaping, and trimming. During the shaping process, the light poles must be straightened to ensure that the straightness tolerance meets the straightness tolerance requirements of the process documentation. Failure to meet these requirements will directly affect the quality of the light poles.

[0003] The following problems are common in the process of straightening lamp poles in the existing technology: 1. During the straightening process, the lamp pole will rotate due to the low position stability of the lamp pole, causing the direction of the outward curved part of the lamp pole to be misaligned; 2. During the straightening process, the straightness of the lamp pole needs to be tested multiple times to ensure that the lamp pole is straightened. This method of determining whether the lamp pole is straightened is cumbersome and not intuitive. Utility Model Content

[0004] In order to address the deficiencies of the above-mentioned prior art, the present application provides a lamp pole straightening device, which has a simple structure and can effectively straighten lamp poles with various curvatures. The device is also provided with a positioning mechanism that can automatically and effectively position the straightened lamp poles.

[0005] In order to achieve the above purpose, the utility model adopts the following technologies:

[0006] A lamp pole straightening device comprises two parallel fixed seats and a linear mechanism disposed between the two fixed seats. The front end surfaces of the fixed seats are each provided with a swinging support block, the swing axes of the two support blocks being vertical, and each support block being provided with a limiting slot, the opening of the limiting slot facing upward or tilted toward the upper side away from the fixed seat, and the extension trajectory of the limiting slot being perpendicular to the swing axis of the corresponding support block. When the support block swings to a predetermined angle, the extension trajectories of the two limiting slots coincide; the movable end of the linear mechanism faces the front end of the fixed seat, the axis of the movable end of the linear mechanism being horizontal and coplanar with the axes of the two limiting slots, and the movable end being movable along its own axis. The movable end of the linear mechanism is provided with a connector for connecting to the lamp pole to be straightened.

[0007] Furthermore, a movable rod is vertically inserted into the front end surface of the fixing seat. The movable rod is movable along the axis, and the support block is hinged to the front end of the movable rod.

[0008] Furthermore, a pair of rotating seats are provided on the front end surface of the movable rod in the vertical direction; a rotating plate is provided at the rear end of the support block, and the rotating plate is rotatably connected to the rotating seat through a pin shaft.

[0009] Furthermore, a positioning pin is vertically provided on the front end face of the fixing seat, which is movable along the axis. A positioning hole for matching the positioning pin is provided on the rear end face of the supporting block. When the extension tracks of the two limiting grooves coincide, the front end of the positioning pin is inserted into the positioning hole.

[0010] Furthermore, the front end of the positioning pin is a spherical structure, and the side wall of the positioning hole is an inclined surface.

[0011] Furthermore, a clamping block is provided on the inner side wall of the limiting groove, and the clamping block is arranged to move in a direction perpendicular to the side wall of the limiting groove.

[0012] Furthermore, one side of the top surface of the clamping block facing the other inner wall of the limiting groove is an inclined surface.

[0013] Furthermore, the fixing seat and the linear mechanism are both arranged on a base.

[0014] The beneficial effects of the utility model are:

[0015] 1. Through the linear mechanism, the setting of the limit groove and the structural design of the clamping block, combined with the swing setting of the support block on the front end of the fixed seat, the lamp pole to be straightened can be easily placed in the limit groove, and the lamp pole to be straightened can be automatically clamped by the clamping block. The limit groove can adapt to the contour of the curved part of the lamp pole to be straightened through the swing of the support block.

[0016] 2. Through the setting of the movable rod, the support block can move in a direction perpendicular to the front end surface of the fixed seat while swinging, so that the limit groove can better accommodate the lamp poles with different curvatures at both ends to be straightened. During the straightening process, the limit groove can further adapt to the contour of the curved part of the lamp pole to be straightened;

[0017] 3. By moving the positioning pin along the axis and setting the front end of the positioning pin to a spherical structure, and then by setting the side of the positioning hole to an inclined surface, the positioning pin can always abut against the rear end face of the support block during the swinging process of the support block. When the front end of the positioning pin slides into the positioning hole, it indicates that the extension trajectories of the two limit grooves coincide, that is, the lamp pole has been straightened.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] The embodiment of the present application provides a lamp pole straightening device, such as Figure 1 As shown, the linear mechanism 5 comprises two parallel fixed seats 3 and a linear mechanism 5 disposed between the two fixed seats 3. The front end surfaces of the fixed seats 3 are each provided with a swinging support block 1. The swing axes of the two support blocks 1 are vertical. Each support block 1 has a limiting slot 11. The opening of the limiting slot 11 faces upward or tilted toward the upper side away from the fixed seat 3. The extension trajectory of the limiting slot 11 is perpendicular to the swing axis of the corresponding support block 1. When the support block 1 swings to a predetermined angle, the extension trajectory of the two limiting slots 11 coincides. The movable end of the linear mechanism 5 faces the front end of the fixed seat 3. The axis of the movable end of the linear mechanism 5 is horizontal and coplanar with the axes of the two limiting slots 11. The movable end is movable along its own axis. The movable end of the linear mechanism 5 is provided with a connector 52 for connecting to the lamp pole to be straightened. The limiting slot 11 can be configured as a U-shaped slot or a V-shaped slot. In this embodiment, the limiting slot 11 is a U-shaped slot. When the limiting slot 11 is a V-shaped slot, its opening direction is tilted toward the upper side away from the fixed seat 3. The linear mechanism 5 is a linear cylinder or a hydraulic cylinder. The connecting member 52 includes an annular seat 511 provided on the movable end of the hydraulic cylinder. A locking ring 512 is provided on the annular seat 511. The locking ring 512 is in a horizontal state. A straightening belt 513 is sleeved on the locking ring 512.

[0025] Specifically, after the two ends of the lamp pole to be straightened are respectively placed in the corresponding U-shaped grooves, since the support block 1 is swingably set at the front end of the fixing seat 3, the inner wall of the U-shaped groove can adapt to the contour of the lamp pole to be straightened with various bending angles; when the lamp pole is placed, the extension tracks of the two U-shaped grooves intersect with each other, and the part of the lamp pole that bends outwards faces the end away from the fixing seat 3; then the straightening belt 513 is put on the bending part of the lamp pole to be straightened, the linear mechanism 5 is operated, and the straightening belt 513 pulls the lamp pole so that the part of the lamp pole that bends outwards faces the fixing seat 3. The seat 3 moves, thereby achieving the purpose of straightening the lamp pole; during the straightening process, the extension trajectories of the two U-shaped grooves gradually overlap; when the extension trajectories of the two U-shaped grooves overlap, the lamp pole has been straightened, and the linear mechanism 5 stops running at this time; the support block 1 is swingably set at the front end of the fixed seat 3, so that the U-shaped groove can adapt to the contours of the lamp pole to be straightened with various curvatures, so as to facilitate the placement of the lamp pole and improve the position stability of the lamp pole; the setting of the two U-shaped grooves makes it possible to judge whether the lamp pole is straightened by observing whether the extension trajectories of the two U-shaped grooves overlap.

[0026] More specifically, in order to achieve the straightening of lamp poles with different curvatures at both ends, Figure 2 and Figure 1 As shown, a movable rod 2 is vertically inserted into the front end face of the fixed seat 3. The movable rod 2 is movable along the axis, and a pair of rotating seats 21 are provided on the front end face of the movable rod 2 in the vertical direction; a rotating plate 13 is provided at the rear end of the support block 1, and the rotating plate 13 is rotatably connected to the rotating seat 21 via a pin 14. Under such a setting, the support block 1 can rotate around the vertical axis and move back and forth in the direction perpendicular to the front end face of the fixed seat, so that the U-shaped groove has more positions and postures to adapt to the contour of the lamp pole to be tested, thereby improving the position stability of the lamp pole to be tested after being placed; the straightening belt 513 pulls the lamp pole to drive the movable rod 2 to retract into the front end face of the fixed seat 3 until the stroke is completed, and then begins straightening. During the above process, the straightening belt 513 pulls the lamp pole, and the contour of the lamp pole further acts on the U-shaped groove, thereby improving the position stability of the lamp pole during the straightening process.

[0027] Specifically, such as Figure 2 As shown, the front end face of the fixing seat 3 is vertically provided with a pin seat 43 and a positioning pin 41. The positioning pin 41 is fitted in the pin seat 43 and is arranged to move along the axis. The front end of the positioning pin 41 is a spherical structure. The rear end face of the support block 1 is provided with a positioning hole 42 for matching the positioning pin 41. The side wall of the positioning hole 42 is an inclined surface. The front end of the positioning pin 41 is inserted into the positioning hole 42. When the extension tracks of the two limiting grooves 11 coincide. Figure 3 and Figure 4As shown, the front end of the locating pin 41 always abuts against the rear end face of the support block 1, and reciprocates along its own axis in the pin seat 43 as the support block 1 swings and moves. When the extension tracks of the two U-shaped grooves coincide, the front end of the locating pin 41 will automatically slide into the locating hole 42 along the side wall of the locating hole 42, effectively positioning the straightened lamp pole, making it easy to observe the straightening status in an intuitive visual manner, and preventing the lamp pole from being bent in the reverse direction.

[0028] Specifically, such as Figure 3 As shown, a clamping block 12 is provided on the inner wall of the U-shaped groove. The clamping block 12 is movable in a direction perpendicular to the inner wall of the U-shaped groove and is used to press the lamp pole into the U-shaped groove to prevent the lamp pole from rotating. The top surface of the clamping block 12 is inclined on one side facing the other inner wall of the U-shaped groove. The setting of the inclined surface of the clamping block 12 and the movable setting of the clamping block 12 play a guiding role for the lamp pole to be straightened placed in the U-shaped groove. The contour of the lamp pole to be straightened contacts the inclined surface. While moving along the inclined surface, the clamping block 12 contracts inward in a direction perpendicular to the inner wall of the U-shaped groove. After the lamp pole to be straightened has completely entered the U-shaped groove, the clamping block 12 extends outward in a direction perpendicular to the inner wall of the U-shaped groove, automatically clamping the lamp pole to be straightened, thereby improving the clamping stability and preventing the lamp pole from rotating during the straightening process.

[0029] Specifically, such as Figure 1 As shown, the fixing seat 3 and the linear mechanism 5 are both arranged on a base 6, so that the device forms an integral structure and is easy to move.

[0030] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
