[0002] During the mold frame processing, it is necessary to punch holes in the side wall of the mold frame plate. However, the drill bits of the current general punching equipment are all located at the top, so the mold frame plate needs to be erected to punch holes in the side wall. However, in actual use, it is found that the stroke of the punching drill bit cannot meet all the requirements for mold frames of different heights. That is, when punching holes in the side wall of a mold frame plate with a smaller height, a pad needs to be set underneath it to increase the height of the end face that needs to be punched, while a mold frame plate with a larger height can be placed directly on the punching platform. This form of operation makes it difficult to clamp and position the mold frame plate, and the operation is complicated and inefficient. Utility Model Content

[0014] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0015] Embodiment 1:

[0016] like Figure 1-Figure 4As shown, the utility model discloses a positioning fixture for vertical processing of a mold frame plate, comprising a bottom plate 1, wherein the bottom plate 1 is used to be fixed under a device for processing the side wall of the mold frame plate. If it is necessary to punch holes in the side wall of the mold frame plate, the bottom plate 1 can be fixed under the punching device. A rectangular ring-shaped fixing cylinder 2 is arranged on the base, and two rows of limiting long holes 3 are arranged on the front and back side walls of the fixing cylinder 2. The limiting long holes 3 are arranged at intervals at both ends of the front and back side walls in the vertical direction. The limiting long holes 3 are in a horizontal state, and the limiting long holes 3 on the front side wall are in a horizontal state. There is a one-to-one correspondence between the long holes 3 and the limiting long holes 3 on the back side wall. Support rods 4 are inserted into the corresponding limiting long holes 3 on the front side wall and the back side wall. The support rods 4 run through the entire fixed tube 2. The support rods 4 are used to support the mold frame plate for vertical processing; a first clamping mechanism is provided on the front side wall and the back side wall of the fixed tube 2 between the two rows of limiting long holes 3, and a second clamping mechanism is provided in the middle of the upper ends of the side walls on both sides of the fixed tube 2. The first clamping mechanism and the second clamping mechanism are used to support the four sides of the mold frame plate for vertical processing.

[0017] The fixed tube 2 is a hollow rectangular parallelepiped structure with an open top, so it is a rectangular ring structure. Two groups of limiting long holes 3 are set on the front side wall and the back side wall of the fixed tube 2, and each group of limiting long holes 3 has four, that is, the four limiting long holes 3 in each group of limiting long holes 3 are arranged in four layers in the vertical direction, and the four limiting long holes 3 in each layer on the two side walls need to be at the same horizontal height. Under normal circumstances, the minimum distance between a layer of limiting long holes 3 on the same side wall is smaller than the width of the mold frame plate to be processed, so that the support rods 4 in the limiting long holes 3 at the appropriate position can be selected according to the height of the mold frame plate to be located at the closest position, that is, two support rods 4 are located at the ends of the limiting long holes 3 that are close to each other, and the support rods 4 in the remaining limiting long holes 3 are located at the ends that are far away from each other, so that the mold frame plate can be mounted on the support rods 4 at a suitable height. The first clamping mechanism is then used to clamp the front and back of the formwork board, and the second clamping mechanism is used to clamp the two sides of the formwork board, so as to clamp the four side walls of the formwork board stably and reliably. This operation method only requires selecting a suitable support rod 4 for support according to the height of the formwork board, which is simple and convenient to operate, greatly improves the clamping efficiency, and has high stability of clamping and fixing.

[0018] The ends of the two groups of limiting long holes 3 that are close to each other extend downward to form an L-shaped structure, and the depth of the limiting long holes 3 extending downward is greater than or equal to the width of the limiting long holes 3. The ends of the limiting long holes 3 that are close to each other extend downward, so when the support rod 4 is needed to support the formwork plate, the support rod 4 can be moved to the portion of the corresponding limiting long hole 3 that extends downward, so that the support rod 4 is stable in the limiting long hole 3 and will not move, and the support for the formwork plate is more stable. The depth of the limiting long hole 3 extending downward is limited to ensure the stability of the portion of the support rod 4 that extends downward in the limiting long hole 3.

[0019] The structure of the first clamping mechanism is as follows: two groups of through holes are arranged on the front or back side wall of the fixed cylinder 2 between the two groups of limiting long holes 3, two of which are located at the upper end of the side wall of the fixed cylinder 2, and two of which are located at the lower end of the side wall of the fixed cylinder 2, and a hydraulic cylinder 5 is arranged on the outer surface of the side wall of the fixed cylinder 2 at each through hole, and the telescopic rod of the hydraulic cylinder 5 extends through the through hole to the inside of the fixed cylinder 2, and a pressure plate 6 is arranged at the end of the telescopic rod of the hydraulic cylinder 5 inside the fixed cylinder 2.

[0020] The first clamping mechanism is arranged on the front and back of the fixed cylinder 2. Due to the existence of the support rod 4, the first clamping mechanism is arranged between the two groups of limiting long holes 3, so that there will be no interference between the first clamping mechanism and the support rod 4. Four through holes are arranged on the side walls of the front and back of the fixed cylinder 2, two of which are located at the upper end and two at the lower end. Preferably, the four through holes can be arranged at the four corners of a rectangle, and a hydraulic cylinder 5 is arranged on the side wall at each through hole. The telescopic rod of the hydraulic cylinder 5 extends through the through hole to the inside of the fixed cylinder 2, and a pressure plate 6 is arranged on the telescopic rod of each hydraulic cylinder 5. When the telescopic rod of the hydraulic cylinder 5 is extended, the pressure plate 6 is pressed on the side wall of the mold frame plate, so as to clamp the mold frame plate.

[0021] Among the four hydraulic cylinders 5 on the same side wall of the fixed cylinder 2, the telescopic rods of the two hydraulic cylinders 5 on the same side are respectively connected to the same long strip-shaped pressing plate 6, and the pressing plate 6 is arranged in the vertical direction. A pressing plate 6 is set on the telescopic rods of the two hydraulic cylinders 5 on the same side, so that the pressing plate 6 is long and basically arranged in a vertical state. This type of pressing plate 6 has a wider clamping range for the formwork plate and high stability. The pressing plates 6 on the hydraulic cylinders 5 on the front and back of the fixed cylinder 2 correspond to each other, so that the clamping of the formwork plate can be kept stable and reliable.

[0022] The structure of the second clamping mechanism is as follows: through holes are provided on the side walls on both sides of the fixed cylinder 2, the through holes are located at the upper ends of the side walls, hydraulic cylinders 5 are provided at the through holes on the side walls on both sides of the fixed cylinder 2, and the telescopic rods of the hydraulic cylinders 5 extend through the through holes to the inside of the fixed cylinder 2.

[0023] The second clamping mechanism is used to clamp the two side walls of the formwork plate, and is arranged on the side walls on both sides of the fixing cylinder 2. The hydraulic cylinder 5 is arranged at the upper end of the side wall, and it is preferably considered to be arranged above the uppermost limiting long hole 3, so that the side wall of the formwork plate can always be clamped.
