Description

Technical Field

[0001] This utility model relates to the field of luggage and bag round pull rod processing technology, and more specifically, it relates to a positioning mechanism for luggage pull rod processing. Background Technology

[0002] In the luggage manufacturing industry, the pull handle is a key component, and its processing quality directly affects the user experience and overall quality of the luggage. Luggage pull handles typically consist of round rods of varying diameters. During processing, to ensure the precision and stability of the pull handle, a positioning mechanism is required for accurate positioning and reliable clamping.

[0003] Currently, while positioning mechanisms for luggage handles on the market can achieve a certain degree of positioning and clamping of the handle, they generally suffer from a significant problem: the distance between the contact points is not easily adjustable. Most existing positioning mechanisms employ a fixed structural design, with the position of the contact points pre-set, making it difficult to flexibly adjust for round handles of different diameters.

[0004] In actual production, due to the diverse specifications of luggage handles, different models of luggage are equipped with handles of varying diameters. When processing round handles of different diameters, existing positioning mechanisms, due to the non-adjustable distance between the contact parts, struggle to effectively clamp handles of different diameters. If the handle diameter is smaller than the preset contact distance, the handle cannot be securely clamped in the positioning mechanism, leading to wobbling and displacement during processing, severely affecting processing accuracy. If the handle diameter is larger than the preset contact distance, the handle cannot be placed into the positioning mechanism at all, causing production disruptions. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a positioning mechanism for processing a suitcase pull rod that can adjust the abutment part.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This utility model is further configured as follows: it includes a housing, a first linear actuator slidably disposed on the top of the housing, a lifting part disposed on the output end of the first linear actuator, a movable frame slidably disposed on the housing, and a grinding roller disposed on the top of the movable frame. The positioning mechanism for the pull rod processing also includes an adjustment mechanism and a grinding dust extraction mechanism. The adjustment mechanism is slidably disposed at the bottom of the lifting part, and the adjustment mechanism includes a displacement part, an ejection part, and an abutment part. The displacement part has a pair and is slidably disposed at the bottom of the lifting part. The ejection part is slidably disposed on the side of the displacement part. The abutment part has multiple parts slidably disposed on the side of the rotating part, and the end face of the rotating part is provided with a linear groove for limiting the sliding of the abutment part. The abutment part is used to abut against the inner side of the circular pull rod to be ground to achieve clamping. When the ejection part slides away from the displacement part, it can drive the abutment part to slide in a relatively distant sliding state.

[0008] By adopting the above technical solution, the problem of inconvenience in adapting to different sizes of round pull rods to be ground is solved, and the effect of convenient and quick clamping of round pull rods to be ground is achieved.

[0009] The present invention is further configured such that: the adjusting mechanism includes a rotating part and a first telescopic cylinder; the rotating part has a pair and is respectively rotatably disposed on the side of the displacement part by bearings, and the rotating part and the ejector part are in clearance fit, so that when the rotating part rotates, it can drive the ejector part and the contact part to rotate synchronously; the first telescopic cylinder has a pair and is respectively disposed on the side of the displacement part, and the output end of the first telescopic cylinder is connected to the ejector part.

[0010] The present invention is further configured such that: the adjusting mechanism also includes a connecting rod; there are multiple connecting rods respectively rotatably disposed on both sides of the ejector portion, one end of the connecting rod is rotatably connected to the ejector portion, and the other end of the connecting rod is rotatably connected to the abutment portion; when the ejector portion slides toward the displacement portion, the connecting rod can tilt and drive the abutment portion to slide in a relatively close sliding state.

[0011] The present invention is further configured such that: the adjusting mechanism includes a first gear, a first rotating rod, and a second gear; the first gear is disposed outside the first telescopic cylinder and is located beside the displacement portion; the first rotating rod has a pair and is disposed beside the displacement portion, and is located above the first gear; the second gear has a pair and is disposed outside the first rotating rod, and meshes with the first gear.

[0012] By adopting the above technical solution, when the first gear rotates, it can drive the first telescopic cylinder, the rotating part, the ejecting part and the abutting part to rotate synchronously. In this state, the abutting part drives the circular pull rod to be ground to rotate in the opposite direction to the grinding roller, thereby improving the grinding efficiency of the circular pull rod to be ground and enabling comprehensive grinding of the circular pull rod to be ground.

[0013] The present invention is further configured such that: the adjusting mechanism includes a first rotary driver and a transmission belt; the first rotary driver has a pair and is respectively arranged on the side of the displacement part, and the pair of first rotary drivers are both located above the first telescopic cylinder; one end of the transmission belt is connected to the first rotating rod, and the other end of the transmission belt is connected to the output end of the first rotary driver.

[0016] By adopting the above technical solution, during the grinding process using the grinding roller, the dust collection pipe draws the waste debris from the grinding process into the dust collection box, thereby reducing the splashing of waste debris and protecting the user's health.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] By incorporating an adjustment mechanism, the problem of adapting to different sizes of circular pull rods to be ground is solved, achieving the effect of convenient and quick clamping of the circular pull rods to be ground. When the rotating part rotates, it drives the ejector part and the abutment part to rotate synchronously. In this state, the abutment part drives the clamped circular pull rod to be ground in the opposite direction of rotation to the grinding roller, thereby improving the grinding efficiency of the circular pull rod and enabling comprehensive grinding of the circular pull rod.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0030] Please see Figure 1-7 The present invention provides the following technical solution:

[0031] Embodiment 1 includes a housing 1, a first linear actuator 2 slidably disposed on the top of the housing 1, a lifting part 3 disposed at the output end of the first linear actuator 2, a movable frame 4 slidably disposed on the housing 1, and a grinding roller 5 disposed on the top of the movable frame 4. The positioning mechanism for the pull rod processing also includes an adjustment mechanism 6 and a grinding dust extraction mechanism 7. The adjustment mechanism 6 is slidably disposed at the bottom of the lifting part 3. The adjustment mechanism 6 includes a displacement part 61, an ejection part 62, and an abutment part 63. The displacement part 61 has a pair and is slidably disposed at the bottom of the lifting part 3. The ejection part 62 is slidably disposed on the side of the displacement part 61. The abutment part 63 has multiple parts slidably disposed on the side of the rotating part 64. The end face of the rotating part 64 is provided with a linear groove for limiting the sliding of the abutment part 63. The abutment part 63 is used to abut against the inner side of the circular pull rod to be ground to achieve clamping. When the ejection part 62 slides away from the displacement part 61, it can drive the abutment part 63 to slide in a relatively distant state.

[0032] A rotary motor, preferably a servo motor, is provided on the side of the movable frame 4 to drive the grinding roller 5 to rotate. When the rotary motor is started, it drives the grinding roller 5 to rotate. The output end of the first linear actuator 2 is provided with a screw threadedly connected to the lifting part 3. When the screw rotates, it drives the lifting part 3 to slide up and down along the top of the housing 1. A second linear actuator is provided on the top of the housing 1 to drive the movable frame 4 to slide. A linear guide rail 41 is also provided on the top of the housing 1 to limit the sliding of the movable frame 4. Both the output ends of the first and second linear actuators are provided with screws, and the screw at the output end of the second linear actuator is threadedly connected to the movable frame 4. When the second linear actuator is started, it drives the movable frame 4 to move horizontally along the linear guide rail 41. A bidirectional screw is provided on the side of the lifting part 3 to drive a pair of displacement parts 61 to move closer and further apart. A servo motor is provided at the input end of the bidirectional screw to drive its rotation. When grinding a circular pull rod, the user first places the rod between a pair of displacement parts 61. Then, the bidirectional screw drives the pair of displacement parts 61 to slide closer together until the displacement parts 61 drive the abutment part 63 to be located on the inner or outer side of the rod. The ejector part 62 slides and drives the abutment part 63 to slide away from each other until the abutment part 63 abuts against the inner side of the rod, thus clamping the inner or outer side of the rod. The abutment part 63 is preferably made of rubber with anti-slip properties, and the position of the abutment part 63 can be adjusted to adjust the circular pull rod.

[0033] See Figures 3-5The adjusting mechanism 6 also includes a rotating part 64 and a first telescopic cylinder 65; the rotating part 64 has a pair and is rotatably disposed on the side of the displacement part 61 by bearings, and the rotating part 64 and the ejector part 62 are in clearance fit, so that when the rotating part 64 rotates, it can drive the ejector part 62 and the abutment part 63 to rotate synchronously; the first telescopic cylinder 65 has a pair and is disposed on the side of the displacement part 61, and the output end of the first telescopic cylinder 65 is connected to the ejector part 62.

[0034] Specifically, after the abutment part 63 clamps the circular pull rod to be ground, the lifting part 3 descends until the circular pull rod to be ground contacts the grinding roller 5. The grinding roller 5 rotates, thereby rotating and grinding the circular pull rod to be ground. In order to drive the ejector part 62 to slide away from the displacement part 61, the first telescopic cylinder 65 is first activated and drives the ejector part 62 to slide away from the displacement part 61. Since the ejector part 62 and the rotating part 64 are in clearance fit, and the rotating part 64 is connected to the displacement part 61 through a bearing, the rotating part 64 can drive the abutment part 63 and the ejector part 62 to rotate synchronously when it rotates. However, when the ejector part 62 slides away from the displacement part 61, it does not drive the rotating part 64 to move synchronously.

[0035] See Figure 4 The adjusting mechanism 6 also includes a connecting rod 66; there are multiple connecting rods 66 which are rotatably disposed on both sides of the ejector 62. One end of the connecting rod 66 is rotatably connected to the ejector 62, and the other end of the connecting rod 66 is rotatably connected to the abutment 63. When the ejector 62 slides toward the displacement part 61, the connecting rod 66 can tilt and drive the abutment 63 to slide in a relatively close sliding state.

[0036] Specifically, when the ejector part 62 slides away from the displacement part 61, the connecting rod 66 is tilted during this process and pushes the abutment part 63 to slide relatively close along the straight groove opened on the rotating part 64, thereby realizing the position adjustment of the abutment part 63, which can be adjusted according to the size change of the circular pull rod to be ground.

[0037] See Figure 5 and Figure 6 The adjusting mechanism 6 also includes a first gear 67, a first rotating rod 68, and a second gear 69; the first gear 67 is disposed outside the first telescopic cylinder 65 and is located beside the displacement part 61; the first rotating rod 68 has a pair and is disposed beside the displacement part 61, and the first rotating rod 68 is located above the first gear 67; the second gear 69 has a pair and is disposed outside the first rotating rod 68, and the second gear 69 meshes with the first gear 67.

[0038] Specifically, when the grinding roller 5 grinds the circular pull rod to be ground, in order to improve the grinding effect, the second gear 69 first rotates, which in turn drives the first gear 67 meshing with the second gear 69 to rotate. When the first gear 67 rotates, it drives the first telescopic cylinder 65, the rotating part 64, the ejecting part 62 and the abutting part 63 to rotate synchronously. In this state, the abutting part 63 drives the circular pull rod to be ground, which is held in the same direction as the rotation of the grinding roller 5, thereby improving the grinding efficiency of the circular pull rod to be ground and enabling comprehensive grinding of the circular pull rod.

[0039] See Figure 6 The adjustment mechanism 6 also includes a first rotary driver 691 and a transmission belt 692; the first rotary driver 691 has a pair and is respectively arranged on the side of the displacement part 61, and the pair of first rotary drivers 691 are both located above the first telescopic cylinder 65; one end of the transmission belt 692 is connected to the first rotating rod 68, and the other end of the transmission belt 692 is connected to the output end of the first rotary driver 691.

[0040] Specifically, in order to drive the first telescopic cylinder 65 to rotate, the first rotary driver 691 is first activated and drives the first rotating rod 68 to rotate via the transmission belt 692. Since the second gear 69 is coaxially fixed with the first rotating rod 68, this achieves the rotational drive of the first rotating rod 68.

[0041] See Figure 7 The grinding and dust collection mechanism 7 includes a mounting plate 71, a dust collection box 72, and a dust collection pipe 73. The mounting plate 71 is slidably disposed above the housing 1 and is connected to the movable frame 4. The dust collection box 72 is disposed on the top of the mounting plate 71. The dust collection pipe 73 is disposed on the side of the dust collection box 72 and is located on the side of the grinding roller 5.

[0042] Specifically, during the polishing process using the polishing roller 5, the dust extraction pipe 73 draws the debris generated during polishing into the dust collection box 72, thereby reducing debris splashing and protecting the user's health.

[0043] See Figure 7 The sanding and dust collection mechanism 7 also includes a filter plate 74 and an air pump 75; the filter plate 74 is slidably disposed on the top of the dust collection box 72; the air pump 75 is disposed on the top of the mounting plate 71 and is connected to the dust collection box 72 through a pipe.

[0044] Specifically, the sucked-in waste is blocked by the filter plate 74, and the sucked-in waste can accumulate on the side of the filter plate 74. The filter plate 74 can slide and be pulled out of the outside of the dust collection box 72 to clean or replace the filter plate 74, and facilitate the dumping of the waste adsorbed inside the dust collection box 72.

[0045] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
