[0002] An end cover is a relatively common mechanical component, which generally refers to a cover installed at the end of a machine, device or component, playing roles such as closing, protecting, supporting, connecting, etc.

[0003] There is a current end cover as Figure 4 shown. A connecting plate for connecting or installing other components is provided at the center of one end thereof, and through holes are provided on the left and right sides near the root of the connecting plate for installing fasteners, etc. When machining this kind of end cover, a machining device such as a drill press is required to open holes thereon, and a fixture is required to fix it during the hole opening process. However, in the prior art, the existing fixture can only play a role of fixing and clamping, and cannot position it. At the same time, only one workpiece can be clamped at a time, resulting in too long machining and clamping time and low production efficiency during batch processing.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a drilling and fixing device for an end cover is provided, in order to achieve a more practical value purpose. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides a drilling and fixing device for an end cover, which is achieved by the following specific technical means:

Two groups of arc surfaces one for clamping are provided on one side of the fixed seat. Two groups of positioning plates are horizontally and fixedly installed on the top of the fixed seat. One ends of the two groups of positioning plates are respectively arranged at the top ends of the arc surfaces one, and U-shaped positioning grooves are provided. A screw rod is rotatably installed between the two groups of arc surfaces one of the fixed seat. One end of the screw rod is threadedly connected with a clamping plate. Two groups of arc surfaces two are provided on the side of the clamping plate opposite to the fixed seat.

[0007] Further, the two groups of arc surfaces two are respectively arranged opposite to the two groups of arc surfaces one and have the same size.

[0008] Further, a through hole is provided on one side of the fixed seat, and a threaded hole is provided on the clamping plate corresponding to the through hole. The threaded end of the screw rod passes through the through hole and is connected with the threaded hole of the clamping plate.

[0009] Further, a connecting seat with a hole is fixedly arranged at the end of the threaded end of the screw rod, and a driving handle is connected through the connecting seat. A flange is provided at the other end of the screw rod, and the diameter of the flange is larger than the diameter of the through hole.

[0010] Further, a support column is vertically and fixedly connected to the center of the top of the clamping plate, and the bottom end of the support column is slidably connected to the bottom plate.

[0011] Further, a T-shaped slider is provided at the bottom end of the support column, and a T-shaped chute slidably connected to the T-shaped slider is provided at the top of the bottom plate.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] By the combined use of the fixed seat, the clamping plate and the screw rod, the utility model can clamp two groups of end caps at one time during use, effectively saving the clamping time for batch processing, effectively improving the drilling efficiency of the overall end caps, and at the same time, through the setting of the positioning plate, rapid positioning of the end caps can be realized during clamping, effectively improving the accuracy of the drilling position, and the overall specific structure is relatively simple and the operation is convenient, which can be well applied to the batch drilling operation of end caps.

[0023] As shown in the attached Figure 1 to the attached Figure 3 figure:

[0024] The present utility model provides a drilling and fixing device for an end cover, which includes a bottom plate 1. A fixing seat 2 is fixedly installed on the top of the bottom plate 1. Two groups of arc surfaces 1 for clamping are arranged on one side of the fixing seat 2. Two groups of positioning plates 3 are horizontally and fixedly installed on the top of the fixing seat 2. One ends of the two groups of positioning plates 3 are respectively arranged at the top ends of the arc surfaces 1, and U-shaped positioning grooves are arranged. The width of the U-shaped positioning grooves matches the thickness of the connecting plate at the center of the end cover, so as to quickly position the end cover during installation and improve the accuracy of drilling operations. A screw rod 5 is rotatably installed between the two groups of arc surfaces 1 of the fixing seat 2. One end of the screw rod 5 is threadedly connected with a clamping plate 4. Two groups of arc surfaces 2 are arranged on the side of the clamping plate 4 opposite to the fixing seat 2.

[0025] Among them, the two groups of arc surfaces 2 are respectively arranged opposite to the two groups of arc surfaces 1 and have the same size, so as to quickly clamp and fix the side of the end cover and ensure high stability during drilling operations.

[0026] Among them, a through hole is arranged on one side of the fixing seat 2, and a threaded hole is arranged on the clamping plate 4 corresponding to the through hole; the threaded end of the screw rod 5 passes through the through hole and is connected with the threaded hole of the clamping plate 4.

[0027] Among them, a connecting seat with holes is fixedly arranged at the end of the threaded end of the screw rod 5, and a driving handle 6 is connected through the connecting seat to facilitate quickly driving the screw rod 5 to rotate to adjust the position of the clamping plate 4; a flange is arranged at the other end of the screw rod 5, and the diameter of the flange is larger than the diameter of the through hole to ensure that the other end of the screw rod 5 will not enter the through hole, causing the clamping to fail.

[0028] Among them, a support column 7 is vertically and fixedly connected to the center of the top of the clamping plate 4, and the bottom end of the support column 7 is slidably connected to the bottom plate 1. Through the arrangement of the support column 7, the stability of the effective clamping plate 4 is improved for easy use.

[0029] Among them, a T-shaped slider is arranged at the bottom end of the support column 7, and a T-shaped sliding groove 101 slidably connected to the T-shaped slider is arranged at the top of the bottom plate 1. Through the cooperation of the T-shaped sliding groove 101 and the T-shaped slider, it can be ensured that the support column 7 has high stability in the vertical direction to prevent the situation of leaving the T-shaped sliding groove 101.

[0030] The working principle of this embodiment: When in use, first fix and install the bottom plate 1 on the machine table of a drilling machine or other processing equipment through fasteners, then place the end cover on one side of the fixed seat 2 and make the connecting plate at the center of its top end located in the U-shaped positioning groove of the positioning plate 3. Then use the driving handle 6 to rotate the screw rod 5 to drive the clamping plate 4 to move towards the end cover to clamp the end cover. After clamping, drilling operations can be carried out. Through the cooperation of the fixed seat 2, the clamping plate 4 and the screw rod 5 of the present utility model, it can be realized that two groups of end covers can be clamped at one time during use, effectively saving the clamping time for batch processing, effectively improving the overall drilling efficiency of the end covers. At the same time, through the arrangement of the positioning plate 3, quick positioning of the end cover can be realized during clamping, effectively improving the accuracy of the drilling position, and the overall specific structure has the advantages of being relatively simple and convenient to operate, and can be well applied to the batch drilling operation of end covers.

[0031] The embodiments of the present utility model are given for purposes of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and to enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.
