Description

Technical Field

[0002] Streetlights typically consist of lamps, poles, arms, and flanges. The poles are formed from steel plates through bending, welding, repairing, and polishing, and are then polished to a smooth and aesthetically pleasing surface. Traditionally, pole polishing is performed manually using a handheld grinder. This method has a low degree of automation, high labor intensity, and low production efficiency. Alternatively, a grinder can be used to polish the pole, but existing grinders typically grind the pole surface by rotating a grinding disc around the pole's axis. This results in a bulky and complex structure, particularly for poles with larger cross-sectional profiles. Utility Model Content

[0025] 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.

[0026] The embodiment of the present application provides a lamp pole grinding device, such as Figure 1 and Figure 2As shown, it includes two placement platforms 1 with hollow interiors and arranged in parallel. The top surfaces of the two placement platforms 1 are recessed to form placement grooves 11 for carrying lamp poles. The extended contours of the two placement grooves 11 overlap and are in a horizontal state; a hollow portion 12 is provided on the placement groove 11 and connected to the interior of the placement platform 1; an adjustment mechanism 2 and a clamping mechanism 3 are provided inside the placement platform 1, and the adjustment mechanism 2 is arranged to move in the vertical direction, and its adjustment end is located within the projection range of the hollow portion along the vertical direction, and is used to rotate the lamp pole carried on the placement groove 11 when the adjustment mechanism 2 moves upward in the vertical direction to a predetermined distance; the clamping part of the clamping mechanism 3 is located within the projection range of the hollow portion along the vertical direction, and is used to clamp the lamp pole carried on the placement groove 11; a grinding mechanism 4 is provided on one side of the two placement platforms 1, which is movable along the direction of the extended contour of the placement groove 11, and is used to grind the lamp pole in the clamping state.

[0027] Specifically, the two ends of the lamp pole to be polished are placed on the two placement grooves 11 respectively, and the adjustment mechanism 2 begins to move upward in the vertical direction until its adjustment end passes through the hollow portion 12 provided on the placement groove 11 and contacts the surface of the lamp pole to be polished. At the same time, the clamping portion of the clamping mechanism 3 is in a separated state; the adjustment end of the adjustment mechanism 2 begins to drive the lamp pole to rotate around the axis, and the welding line or other defects generated by the lamp pole welding are directed toward the side where the polishing mechanism 4 is provided; thereafter, the adjustment mechanism 2 begins to move downward in the vertical direction, and at the same time, the clamping portion of the clamping mechanism 3 is linked to be in a retracted state, thereby clamping the lamp pole; the polishing mechanism 4 begins to move in the direction of the extended contour of the placement groove 11, and polishes the welding line or other defects on the surface of the lamp pole. The linkage setting of the adjustment mechanism 2 and the clamping mechanism 3, and the cooperation with the polishing mechanism 4 realize the automatic polishing of the welding line or other defects on the surface of the lamp pole.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, the hollow portion 12 includes two first channel grooves 121, which are respectively located on both sides of the extended contour axis of the placement groove 11, serving as channels for the operation of the adjustment end of the adjustment mechanism 2; the hollow portion 12 also includes two second channel grooves 122, which are respectively located on both sides of the extended contour axis of the placement groove 11, serving as operation channels for the separation or retraction of the clamping part in the clamping mechanism 3.

[0029] like Figures 2-4As shown, a third linear mechanism 6 is provided below the lifting plate 21. In this embodiment, the third linear mechanism 6 adopts a linear cylinder. The movable end of the linear cylinder is vertically upward and connected to the bottom of the lifting plate 21, so that the adjustment mechanism 2 can realize the function of moving smoothly in the vertical direction; two pairs of parallel fixed frames 22 are provided on the lifting plate 21, and fixed shafts 23 are provided above the two pairs of fixed frames 22. The two fixed shafts 23 are parallel to each other. Pulleys 24 are rotatably provided on the two fixed shafts 23, and the two pulleys 24 can pass vertically through the first channel groove 121; a driving wheel 25 is provided below the pulley 24, and the driving wheel 25 is connected to the driving end of a first drive motor 26. The first drive motor 26 is installed on the lifting plate 21, and the rotation axes of the two fixed shafts 23 and the driving end of the first drive motor 26 are parallel to each other, and the two fixed shafts 23 are connected to the driving end of the first drive motor 26 through a connecting frame 28. Belts 27 are sleeved on the driving wheel 25 and the two pulleys 24 to realize belt transmission. By setting up the connecting frame 28, when the lifting plate 21 moves in the vertical direction, the belt 27 always cooperates well with the driving pulley 25 to maintain the transmission efficiency of the belt drive and the efficiency of the adjustment mechanism 2 in adjusting the lamp pole; the friction coefficient on the surface of the belt 27 should be reasonably set, that is, the pulley 24 can smoothly drive the lamp pole to rotate around the axis without slipping, and when the pulley 24 rotates, the belt 27 will not produce scratches on the surface of the lamp pole; the two pulleys 24 are driven by a driving pulley 25 through the belt drive method, which not only can adjust the position of the lamp pole, but also optimize the structure of the device.

[0030] like Figure 5 and Figure 6 As shown, the clamping mechanism 3 includes two clamping plates 31 arranged opposite to each other, the bottom of the clamping plate 31 is rotatably connected to the lifting plate 21, and the rotation axes of the two clamping plates 31 are respectively located on both sides of the extended contour axis of the placement groove 11, and the three are parallel to each other; guide grooves 32 are provided on both sides of the length direction of the two second channel grooves 122, and matching blocks 311 are provided on both sides of the middle part of the clamping plate 31, and the matching blocks 311 are slidably fitted in the guide grooves 32; clamping blocks 312 are provided on the upper parts of the two clamping plates 31 facing each other.

[0031] Specifically, two pairs of rotating seats 22 are provided on the lifting plate 21, and are respectively located on both sides of the extended contour axis of the placement slot 11. A rotating shaft 313 is formed at the bottom of the clamping plate 31. The rotating shaft 313 fits in the rotating seat 211, and the rotating shaft 313 is parallel to the extended contour axis of the placement slot 11. When the position adjustment of the lamp pole is completed, the movable end of the linear cylinder moves downward in the vertical direction, and the matching blocks 311 provided on both sides of the middle of the clamping plate 31 fit in the guide slot 32, so that the matching blocks 311 are close to the extended contour axis of the placement slot 11 in the guide slot 32, and the clamping plate 31 also rotates around the rotating shaft 313, and the two clamping plates 31 gradually retract, and the movable end of the linear cylinder continues to move downward in the vertical direction until the two clamping plates 31 clamp the lamp pole; when the position of the lamp pole needs to be adjusted, the movable end of the linear cylinder moves upward in the vertical direction, so that the matching blocks 311 move in the guide slot 32. , and extends the contour axis away from the placement groove 11, the clamping plate 31 cooperates to rotate around the rotating shaft 313, and the two clamping plates 31 gradually separate, so that the lamp pole is out of the clamping state, and then adjusted by the adjustment mechanism 2; the shape of the clamping block 312 can be set to V-shaped or the surface of the clamping block 312 in contact with the lamp pole can be set to an arc surface or other structure that can adapt to different lamp pole sizes. This embodiment adopts the method of setting the contact surface to an arc surface; through the above settings, the clamping plate 31 of the clamping mechanism 3 can automatically cooperate with the operation of the adjustment mechanism 2 to automatically clamp the lamp pole, and is suitable for clamping lamp poles of different sizes.

[0032] like Figure 1 As shown, the grinding mechanism 4 includes a first linear mechanism 41 arranged along the direction of the extended contour of the placement groove 11, and its movable end is connected to a second linear mechanism 42. The movable end of the second linear mechanism 42 is perpendicular to the extended contour axis of the placement groove 11 and is connected to a second drive motor 43. The driving end of the second drive motor 43 is connected to a grinding wheel 44, and the rotation axis of the grinding wheel 44 is parallel to the extended contour axis of the placement groove 11.

[0033] Specifically, the second linear mechanism 42 in the grinding mechanism 4 of this embodiment adopts a linear screw, whose movable end is connected to a movable platform 46. Guide rails 45 are provided on both sides of the linear mechanism 42. The guide rails 45 are parallel to each other and face the extension and contraction direction of the linear mechanism 42. The bottom of the movable platform 46 moves and cooperates with the guide rails 45; the top of the movable platform 46 is provided with a grinding wheel frame 47 and a second linear mechanism 42. In this embodiment, the second linear mechanism 42 adopts a linear cylinder, whose movable end is horizontal and perpendicular to the extending contour axis of the placement slot 11, and is connected to one side of the grinding wheel frame 47. The second drive motor 43 is connected to the upper part of the other side of the grinding wheel frame 47, and the driving end of the second drive motor 43 is connected to the grinding wheel 44. When the position adjustment of the lamp pole is completed and it is in a clamping state, the second linear mechanism 42 drives the grinding wheel frame 47 to move, thereby driving the grinding wheel 44 to approach the lamp pole until the grinding wheel 44 contacts the welding line or other defective parts on the surface of the lamp pole. After that, the first linear mechanism 41 drives the movable platform 46 to move along the extended contour axis of the placement groove 11, thereby driving the grinding wheel 44 to move along the lamp pole, thereby completing the grinding of the lamp pole surface.

[0034] Specifically, such as Figure 1 As shown, the placement table 1, the grinding mechanism 4, and the guide rail 45 are all installed on a base 5, which optimizes the device structure and improves the degree of integration.

[0035] Specifically, such as Figure 1 and Figure 2 As shown, the cross-sectional profile of the placement groove 11 is V-shaped, so that the placement groove 11 can stably support lamp poles of various cross-sectional shapes or sizes.

[0036] 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.
