Description

Technical Field

[0001] The utility model relates to the technical field of support frames, in particular to a support frame for mechanical manufacturing. Background Technique

[0002] Mechanical manufacturing refers to the industrial department engaged in the production of various power machinery, hoisting and transportation machinery, chemical machinery, textile machinery, machine tools, tools, instruments, meters and other mechanical equipment. The mechanical manufacturing industry provides technical equipment for the entire national economy. The production process of a product refers to the whole process of turning raw materials into finished products. In the actual production and experimental measurement processes, the safety, stability and accuracy of the storage position of materials directly affect the effective progress of subsequent processes such as part picking, guiding, assembly and measurement. Therefore, it is of great practical significance to achieve accurate support for materials.

[0003] Although the existing support devices have various functions such as being movable, liftable and clamping and fixing, they still have certain defects. For example, the overall structure of the device is relatively large and cannot be folded and stored, which is not convenient for storage. Therefore, we design a support frame for mechanical manufacturing to solve the above technical problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a support frame for mechanical manufacturing to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] A support frame for mechanical manufacturing includes a bottom plate. Universal wheels with brakes are provided at the four corners of the bottom of the bottom plate. A push rod is provided on the right surface of the bottom plate. Side plates are symmetrically arranged on the left and right of the top of the bottom plate. The bottom of the side plates is slidably connected to the top of the bottom plate. A lifting plate is provided at the top of the side plates. A clamping assembly is provided at the top of the lifting plate. A first groove is horizontally opened in the middle of the top surface of the bottom plate. A first threaded rod is rotatably provided between the inner walls on the left and right sides of the first groove. Two sets of first external threads with opposite directions are provided on the first threaded rod. The two sets of first external threads are symmetrically distributed on both sides of the midpoint of the length direction of the first threaded rod. Two rectangular sliders adapted to the first groove are slidably provided in the first groove. The rectangular sliders are threadedly sleeved outside the first threaded rod. A motor is fixedly provided on the right surface of the bottom plate. The output shaft of the motor extends into the first groove and is connected to one end of the first threaded rod. Two sets of auxiliary components are provided on the top of the bottom plate. The two sets of auxiliary components are symmetrically distributed in front and behind the first groove.

[0007] As a preferred embodiment of the present utility model: The auxiliary component includes a connecting groove connecting two receiving grooves. The connecting groove is of a dovetail groove structure and is arranged parallel to the first groove. The four receiving grooves are respectively distributed at the four corners of the top of the bottom plate. A dovetail slider adapted to the connecting groove is provided at the bottom of the side plate. One ends of the tops of the two rectangular sliders close to each other are respectively rotatably connected to the corresponding side plates through a plurality of hinges, and the two side plates rotate in opposite directions.

[0008] As a further preferred embodiment of the present utility model: The clamping component includes a rotating handle, a second threaded rod and a clamping block. A second groove is formed at the top of the lifting plate. A second threaded rod is rotatably provided between the left and right side walls of the second groove. Two sets of second external threads in opposite directions are provided on the second threaded rod, and two connecting blocks matched with the second threaded rod are threadedly sleeved on the second threaded rod. The connecting block is slidably connected to the inner wall of the second groove. The top of the connecting block is fixedly connected with a clamping block. The bottom of the clamping block is slidably connected to the top of the lifting plate. The two clamping blocks are symmetrically distributed on the left and right sides of the top of the lifting plate. A rotating handle is rotatably provided on the front surface of the lifting plate. The front end of the second threaded rod is connected to the rotating handle. Rubber layers are provided on the sides of the two clamping blocks close to each other.

[0009] As a further preferred embodiment of the present utility model: A cavity is provided inside the side plate, and a plurality of electric push rods are provided inside the cavity. The extending ends of the plurality of electric push rods vertically penetrate upward to the outside of the cavity and are fixedly connected to the bottom of the lifting plate.

[0010] As a further preferred embodiment of the present utility model: The size of the connecting groove is larger than the size of the dovetail slider. When the two rectangular sliders are farthest apart, the dovetail slider moves into the corresponding receiving groove.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. By setting the auxiliary component in the present utility model, when the two rectangular sliders are farthest apart, the dovetail slider moves into the corresponding receiving groove. At this time, the side plate can be rotated so that the side plate rotates from the vertical state to the horizontal state, as shown in the figure and the figure. It should be noted that when the side plate rotates from the horizontal state to the vertical state, the motor is started, and the motor drives the first threaded rod to rotate. Under the action of the two sets of first external threads in opposite directions, the two rectangular sliders can move closer to each other, which can drive the two side plates to move closer to each other. Correspondingly, the dovetail slider slides into the corresponding connecting groove. On the one hand, it plays a role in guiding and stabilizing the movement of the side plate. On the other hand, the cooperation between the dovetail slider and the connecting groove can limit the rotation of the side plate, that is, the side plate can only move in the horizontal direction and cannot rotate under the action of the hinge. Therefore, the stability of the subsequent support operation can be guaranteed. Therefore, when the device is not in use, it can be folded and stored, which is easy to store and does not occupy space resources.

[0013] 2. When the present utility model is in use, the staff rotates the turning handle to drive the second threaded rod. Under the action of two sets of second external threads with opposite directions, the connecting block can drive two clamping blocks to approach each other, thereby clamping and fixing the workpiece. At the same time, since the two side plates can move towards or away from each other, the device can support and fix workpieces with different sizes, has high applicability, and is easy to operate. In addition, when the height of the side plate cannot meet the actual use requirements, the electric push rod can be started. The extending end of the electric push rod extends, driving the lifting plate to move upward, that is, driving the workpiece to move upward to meet the use needs and further improving the applicability of the device.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0020] Please refer to Figures 1-4, in the embodiment of the present utility model, a support frame for mechanical manufacturing includes a bottom plate 1. Universal wheels 2 with brakes are provided at the four corners of the bottom of the bottom plate 1. A push rod 3 is provided on the right surface of the bottom plate 1. Side plates 4 are symmetrically arranged on the top of the bottom plate 1 in the left and right directions. The bottom of the side plate 4 is slidably connected to the top of the bottom plate 1. A lifting plate 5 is provided at the top of the side plate 4. A clamping assembly is provided at the top of the lifting plate 5. A first groove 20 is horizontally opened in the middle of the top surface of the bottom plate 1. A first threaded rod 16 is rotatably provided between the inner walls on the left and right sides of the first groove 20. Two sets of first external threads with opposite directions are provided on the first threaded rod 16. The two sets of first external threads are symmetrically distributed on both sides of the midpoint in the length direction of the first threaded rod 16. Two rectangular sliders 17 adapted to it are slidably provided in the first groove 20. The rectangular sliders 17 are threadedly sleeved outside the first threaded rod 16. A motor 18 is fixedly provided on the right surface of the bottom plate 1. The output shaft of the motor 18 extends into the first groove 20 and is connected to one end of the first threaded rod 16. Two sets of auxiliary components are provided on the top of the bottom plate 1. The two sets of auxiliary components are symmetrically distributed in front of and behind the first groove 20.

[0021] The auxiliary component includes a connecting groove 15 connecting two receiving grooves 19. The connecting groove 15 is of a dovetail groove structure. The connecting groove 15 is arranged parallel to the first groove 20. The four receiving grooves 19 are respectively distributed at the four corners of the top of the bottom plate 1. A dovetail slider 10 adapted to the connecting groove 15 is provided at the bottom of the side plate 4. One ends of the two rectangular sliders 17 close to each other at the top are respectively rotatably connected to the corresponding side plates 4 through a plurality of hinges 14. The two side plates 4 rotate in opposite directions. The size of the connecting groove 15 is larger than the size of the dovetail slider 10. When the two rectangular sliders 17 are farthest apart, the dovetail slider 10 moves into the corresponding receiving groove 19. At this time, the side plate 4 can be rotated so that the side plate 4 rotates from the vertical state to the horizontal state, as Figure 3 and Figure 4 shown. It should be noted that when the side plate 4 rotates from the horizontal state to the vertical state, the motor 18 is started. The motor 18 drives the first threaded rod 16 to rotate. Under the action of the two sets of first external threads with opposite directions, the two rectangular sliders 17 can move closer to each other, and then the two side plates 4 can be driven to move closer to each other. Correspondingly, the dovetail slider 10 slides into the corresponding connecting groove 15. On the one hand, it plays a role in guiding and stabilizing the movement of the side plate 4. On the other hand, the cooperation between the dovetail slider 10 and the connecting groove 15 can limit the rotation of the side plate 4, that is, the side plate 4 can only move in the horizontal direction and cannot rotate under the action of the hinge 14. Therefore, the stability of the subsequent support operation can be ensured. Therefore, when the device is not in use, it can be folded and stored, which is easy to store and does not occupy space resources.

[0022] The clamping assembly includes a rotating handle 7, a second threaded rod 13 and a clamping block 6. A second groove 11 is formed at the top of the lifting plate 5.

The two clamping blocks 6 are symmetrically distributed on the left and right sides of the top of the lifting plate 5. A rotating handle 7 is rotatably provided on the front surface of the lifting plate 5. The front end of the second threaded rod 13 is connected to the rotating handle 7. Rubber layers 12 are provided on the sides of the two clamping blocks 6 that are close to each other. When in use, the staff rotates the rotating handle 7 to drive the second threaded rod 13. Under the action of the two sets of second external threads with opposite directions, the two clamping blocks 6 can be driven to approach each other through the connecting blocks, so as to clamp and fix the workpiece. At the same time, since the two side plates 4 can move towards or away from each other, the device can support and fix workpieces with different sizes, has high applicability and is easy to operate.

[0023] A cavity 9 is provided inside the side plate 4. A plurality of electric push rods 8 are provided inside the cavity 9. The extending ends of the plurality of electric push rods 8 vertically penetrate upward to the outside of the cavity 9 and are fixedly connected to the bottom of the lifting plate 5.
