Description

Technical Field

[0001] The utility model belongs to the technical field of caster manufacturing devices, in particular to an air pressure feeding device. Background Art

[0002] During the production of casters, the connecting pieces are mostly formed by stamping metal plates. Therefore, a feeding device is needed to feed the metal plates under the stamping die during stamping. In the existing technology, air-compressed feeding devices are often used for feeding. The principle is to convert the energy of compressed air into mechanical energy to drive the raw materials to move.

[0003] Chinese invention patent CN104340613A discloses a single-cylinder feeding device and a feeding method thereof. The provided single-cylinder feeding device and a feeding method thereof only require one power source to achieve positioning and transportation of materials. They have a simple structure and low production cost. At the same time, they can improve production efficiency and save space for the feeding mechanism.

[0004] The pneumatic feeding in the existing technology cannot be adjusted according to the volume of the material to be pushed. Due to the various sizes of casters, the sizes of metal plates used for stamping are also different. During pneumatic feeding, the positioning of the raw materials must be ensured at all times. Therefore, raw materials of different sizes cannot be used in the same pneumatic feeding device. Utility Model Content

[0005] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and in the abstract and title of the utility model to avoid obscuring the purpose of this section, the abstract and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the present invention.

[0006] In order to solve the problems raised in the above background technology, the present invention adopts the following technical solutions.

[0008] The upper surface of the bottom plate is symmetrically provided with vertical plates, the adjustment box is located between a pair of vertical plates, and the limiting beams are symmetrically installed between the pair of vertical plates. The distance between the limiting beams is less than the length of the supporting plate, and the push plate is located between the lower surface of the limiting beams and the upper surface of the supporting plate;

[0009] A support block is assembled in the adjusting box, and the support block passes through the upper surface of the adjusting box, and the support plate is installed on the upper surface of the support block. A rack is provided on one side of the support block, and a gear column is provided on one side of the rack. A rotating shaft is connected to the center of the gear column, and both ends of the rotating shaft pass through both sides of the adjusting box. One end of the rotating shaft is connected to a limit block, and a limit sleeve is provided on the outer surface of one side of the corresponding adjusting box, and the limit block is slidably connected in the limit sleeve.

[0010] The length of the rotating shaft is longer than that of the adjusting box. The end of the rotating shaft away from the limit block extends outside the adjusting box. The end of the rotating shaft close to the limit block is sleeved with a spring, which is fixed on the inner wall of the adjusting box. A resistance block is provided on the rotating shaft near the spring.

[0011] One end of the rotating shaft extending outside the regulating box is provided with levers at equal intervals in a circular pattern. Pressing one end of the rotating shaft with the lever causes the end of the rotating shaft connected to the limit block to protrude outward, causing the limit block to disengage from the limit sleeve. Rotating the rotating shaft controls the rotation of the gear column to drive the support block connected to the rack to rise and fall.

[0012] The other side of the support block is in contact with the inner wall of the adjustment box, and a slide bar is provided on the side where the support block is in contact with the inner wall of the adjustment box, and a slide groove is provided on the corresponding inner wall of the adjustment box. Limiting columns are symmetrically provided on the lower surface of the support plate, and a through hole is provided on the upper surface of the adjustment box for the limiting columns to move.

[0013] A waist hole is provided on the vertical plate, and one of the limit beams is arranged at the waist hole and has bolts threadedly connected at both ends. The bolts pass through the waist hole and are connected to the limit beam arranged at the waist hole. The limit beam arranged at the waist hole is fixed to any point of the waist hole by tightening the bolts.

[0014] The compression cylinder can be connected to an external air compressor, which provides compressed air to realize the outward movement of the output end of the compression cylinder, thereby pushing the push plate to move between the lower surface of the limit beam and the upper surface of the support plate.

[0015] A guide plate is also installed on the upper surface of the base plate. The guide plate is sloped and has a hollow structure. The installation position of the guide plate is opposite to the position of the compression cylinder, and the top of the guide plate is at the same height as the upper surface of the adjustment box.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) In the present invention, the gear column is driven to rotate by the rotating shaft, and the gear column cooperates with the rack to control the lifting of the support block, thereby realizing the adjustment of the height of the support plate, thereby controlling the distance between the support plate and the limiting beam. The mechanical structure of the gear column and the rack can realize relatively precise height adjustment, meeting the application with precise requirements for the height of the support plate, and is suitable for metal plates of different thicknesses. It ensures that the compression cylinder can push the metal plate smoothly while the metal plates stacked above will not be offset under the constraint of a pair of limiting beams, and the mounting frame is installed on the bottom plate for installing the compression cylinder, making the whole structure compact. The compression cylinder can be connected to an external air compressor to facilitate the acquisition of power source and realize the movement of the push plate.

[0018] (2) In the present invention, a lever is provided at one end of the rotating shaft extending outside the adjustment box. The operator can press the lever to disengage the limit block from the limit sleeve and then rotate the rotating shaft. This design makes the adjustment operation of the height of the support plate relatively convenient and does not require complicated tools or too many operating steps. Furthermore, the support plate is installed on the support block, and the support block and the inner wall of the adjustment box cooperate with the sliding bar and the sliding groove, so that the support plate can maintain good stability during the lifting process.

[0019] (3) In the present invention, a waist hole is opened on the vertical plate, and the limiting beam is set at the waist hole and connected by bolts. This design allows the distance between the limiting beams to be adjusted according to actual needs. The limiting beam is fixed at any point of the waist hole by tightening the bolts, which improves the flexibility of the device and can adapt to metal plates of different sizes.

[0020] (4) The guide plate installed on the bottom plate of the present invention is sloped and hollowed out. Its installation position is opposite to the compression cylinder, and its top end is at the same height as the upper surface of the adjustment box. When the metal plate is pushed down by the air pressure feeding, the guide plate can play a guiding role, allowing the metal plate to more conveniently reach the stamping work area. While ensuring the guiding function, the hollow structure can also reduce the overall weight of the device and the contact with the metal plate, reducing friction and wear.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0032] See Figure 1 and Figure 2The structure diagram of an air pressure feeding device in this embodiment is shown. The air pressure feeding device in this embodiment includes a base plate 100. The upper surface of the base plate 100 is equipped with an adjustment box 103. The upper surface of the adjustment box 103 is movably connected to a support plate 1039. The upper surface of the base plate 100 and one side of the adjustment box 103 are equipped with a mounting bracket 1042. A compression cylinder 104 is installed on the mounting bracket 1042. A push plate 1041 is installed at the output end of the compression cylinder 104, and the height of the push plate 1041 is higher than the upper surface of the support plate 1039. In this embodiment, the connecting rod for stamping casters is used. The metal plates of the connecting piece are stacked and placed on the support plate 1039. The output end of the compression cylinder 104 is used to control the extension and contraction of the push plate 1041 to push the bottom metal plate outward. Furthermore, to ensure power, the compression cylinder 104 in this embodiment can be connected to an external air compressor. The air compressor provides compressed air to realize the outward movement of the output end of the compression cylinder 104, thereby pushing the push plate 1041 to move between the lower surface of the limiting beam 1011 and the upper surface of the support plate 1039. In this embodiment, the energy of the compressed air is converted into mechanical energy by the compression cylinder 104 to push the metal plate to move.

[0033] See Figure 1-3 1039 . Offset will occur. In this embodiment, a plurality of plug-in holes are opened on the limit beam 1011, and a blocking column 1012 is inserted into the plug-in hole; further, in this embodiment, a waist hole is opened on the vertical plate 101, and one of the limit beams 1011 is set at the waist hole and is threadedly connected with bolts at both ends. The bolts pass through the waist hole and are connected to the limit beam 1011 set at the waist hole, and the limit beam 1011 set at the waist hole is fixed to any part of the waist hole by tightening the bolts. In this embodiment, a waist hole is opened on the vertical plate 101, and the limit beam 1011 is set at the waist hole and is connected by bolts. This design enables the distance between the limit beams 1011 to be adjusted according to actual needs, and the limit beam is fixed to any part of the waist hole by tightening the bolts, which improves the flexibility of the device and can adapt to pallets of different sizes or working requirements.

[0034] See Figure 4-6In this embodiment, a support block 1031 is assembled in the regulating box 103, and the support block 1031 passes through the upper surface of the regulating box 103, and a support plate 1039 is installed on the upper surface of the support block 1031. A rack 1033 is provided on one side of the support block 1031, and a gear column 1035 is provided on one side of the rack 1033. A rotating shaft 1034 is connected to the center of the gear column 1035. The two ends of the rotating shaft 1034 pass through the two sides of the regulating box 103 and are connected by bearings. In the embodiment, the gear column 1035 is driven to rotate by the rotating shaft 1034. The gear column 1035 cooperates with the rack 1033 to control the lifting and lowering of the support block 1031, thereby adjusting the height of the support plate 1039, thereby controlling the distance between the support plate 1039 and the limiting beam 1011. The mechanical structure of the gear column 1035 and the rack 1033 can achieve relatively precise height adjustment, meeting the application of precise requirements for the height of the support plate 1039 and being suitable for metal plates of different thicknesses.

[0035] Furthermore, in this embodiment, one end of the rotating shaft 1034 is connected to a limiting block 1037, and the outer surface of one side of the corresponding adjustment box 103 is provided with a limiting sleeve 1038, and the limiting block 1037 is slidably connected to the limiting sleeve 1038. The rotating shaft 1034 extends to one end outside the adjustment box 103 and is equidistantly provided with a shift rod in a circular manner. The other side of the support block 1031 is in contact with the inner wall of the adjustment box 103, and a sliding bar 1032 is provided on the side where the support block 1031 is in contact with the inner wall of the adjustment box 103. The corresponding inner wall of the adjustment box 103 is provided with a sliding groove, and the lower surface of the support plate 1039 is symmetrically provided with limiting columns, and the upper surface of the adjustment box 103 is provided with a through hole for The limiting column is movable. In this embodiment, one end of the lever provided on the rotating shaft 1034 is pressed to make the end of the rotating shaft 1034 connected to the limiting block 1037 protrude outward, causing the limiting block 1037 to disengage from the limiting sleeve 1038. The rotating shaft 1034 is rotated to control the gear column 1035 to rotate and drive the support block 1031 connected to the rack 1033 to rise and fall. This design makes the height adjustment operation of the support plate 1039 relatively convenient and does not require complicated tools or too many operating steps. Furthermore, the support block 1031 and the inner wall of the adjustment box 103 cooperate with the slide bar 1032 and the slide groove, so that the support plate 1039 can maintain good stability during the lifting process.

[0036] It is worth noting that in order to ensure that the rotating shaft 1034 has sufficient length for the operator to hold and rotate after being pressed, the length of the rotating shaft 1034 in this embodiment is longer than the length of the adjusting box 103. At the same time, in order to achieve the reset of the rotating shaft 1034, the rotating shaft 1034 in this embodiment extends to the outside of the adjusting box 103 at one end away from the limit block 1037. A spring 1036 is sleeved on the end of the rotating shaft 1034 close to the limit block 1037. The spring 1036 is fixed on the inner wall of the adjusting box 103. A resistance block is provided on the rotating shaft 1034 near the spring 1036, and the reset of the rotating shaft 1034 is achieved by the rebound force of the spring 1036.

[0037] See Figure 1 In this embodiment, a guide plate 105 is further installed on the upper surface of the base plate 100. The guide plate 105 is sloped and has a hollow structure. The installation position of the guide plate 105 is opposite to the position of the compression cylinder 104, and the top of the guide plate 105 is at the same height as the upper surface of the adjustment box 103. The guide plate 105 can play a guiding role, so that the metal plate can more conveniently reach the stamping working area. The hollow structure can not only ensure the guiding function, but also reduce the overall weight of the device and the contact with the metal plate, thereby reducing friction and wear.

It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the concept of the present invention, which should be regarded as falling within the scope of protection determined by the claims submitted for the present invention.
