Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] See attached document Figure 1-7 The present invention will be described through the following embodiments.

[0028] Example 1

[0029] This embodiment provides a manual press, including an upper crossbeam 1 and a lower crossbeam 2 arranged in parallel. The two ends of the upper crossbeam 1 and the lower crossbeam 2 are respectively connected by two lifting adjustment mechanisms 3. It also includes a pressing screw 4 and a lifting device 5. A reinforcing mechanism 6 is provided in the middle of the upper crossbeam 1. The pressing screw 4 and the reinforcing mechanism 6 are connected by a transmission. A base plate 7 is provided in the middle of the lower crossbeam 2. The lifting device 5 is provided on the base plate 7. An upper support plate 8 is provided on the top of the lifting device 5.

[0030] The clamping screw 4 is located above the center of the upper support plate 8. The clamping screw 4 and the lifting device 5 work together to assemble or disassemble the workpiece located on the upper support plate 8.

[0031] In this embodiment, the workpiece to be assembled or disassembled is placed on the upper support plate 8. The distance between the clamping screw 4 and the upper support plate 8 is adjusted according to the size of the workpiece by the lifting device 5 and the clamping screw 4. After adjustment, the clamping screw 4 is moved down to apply force to the workpiece, and the parts are assembled or disassembled. The operation is simple, and the disassembly and assembly costs are low, making it economical.

[0032] Example 2

[0033] Based on the above embodiments, the structures of the upper crossbeam 1 and the lower crossbeam 2 in this embodiment both include two side plates 9 and a horizontal plate 10. The horizontal plate 10 connects the two side plates 9 and forms an H-shape with the two side plates 9; the two sides of the horizontal plate 10 are respectively provided with connecting holes 11 corresponding to the two lifting adjustment mechanisms 3. Figure 4 As shown.

[0034] Example 3

[0035] Based on the above embodiments, the lifting and adjusting mechanism 3 of this embodiment includes a hollow outer column 31 and an inner column 32, with the inner column 32 inserted into the outer column 31, as shown below. Figure 1 and 2 As shown, the inner column 32 is installed through the corresponding connection hole 11 of the upper crossbeam 1, and the outer column 31 is installed through the corresponding connection hole 11 of the lower crossbeam 2.

[0036] In this embodiment, because the outer diameters of the outer column 31 and the inner column 32 are different (the outer diameter of the outer column 31 is larger than that of the inner column 32), the diameter of the connecting hole 11 on the upper crossbeam 1 is smaller than the diameter of the connecting hole 11 on the lower crossbeam 2. That is, the diameters of the connecting holes 11 on the upper crossbeam 1 and the lower crossbeam 2 match the diameters of the corresponding inner column 32 and outer column 31.

[0037] Example 4

[0038] Based on the above embodiments, the lifting adjustment mechanism 3 of this embodiment further includes a pin 33, such as Figure 3 As shown, the inner column 32 is provided with a row of insertion holes 34 evenly along the axial direction, and the top of the outer column 31 is also provided with a group of insertion holes 34. Each group of insertion holes 34 includes two opposite insertion holes 34 on the inner column 32 or the outer column 31. The inner column 32 and the outer column 31 are fixed by a pin 33 passing through the group of insertion holes 34 on the inner column 32 and the outer column 31.

[0039] In this embodiment, the distance between the clamping screw 4 and the upper support plate 8 is adjusted according to the size of the workpiece to be processed. Specifically, the inner column 32 is moved vertically to a suitable position inside the outer column 31. After aligning the insertion holes 34 of the inner column 32 with the insertion holes 34 at the top of the outer column 31, the pin 33 is inserted into the insertion holes 34 of the outer column 31 and the inner column 32 for fixation. This facilitates the processing of workpieces of different sizes and provides flexible use.

[0040] Example 5

[0041] Based on the above embodiments, the structure connecting the lifting adjustment mechanism 3 and the upper crossbeam 1 and lower crossbeam 2 in this embodiment is as follows: Figure 1 and 2 As shown, the inner column 32 and the outer column 31 are respectively fixed above the horizontal plate 10 of the upper beam 1 and below the horizontal plate 10 of the lower beam 2 by flanges 12. The flange 12 is convex in shape. The top of the inner column 32 and the bottom of the outer column 31 are respectively installed through the flange 12. The part with a larger outer diameter of the flange 12 is fixed to the horizontal plate 10 by bolts, and the part with a smaller outer diameter is tightened inward to the inner column 32 or the outer column 31 by bolts.

[0042] In this embodiment, because the outer diameters of the inner column 32 and the fixed outer column 31 are different, the inner diameter of the flange 12 through which the inner column 32 passes is smaller than the inner diameter of the flange 12 through which the outer column 31 passes. The inner column 32 and the outer column 31 are detachably fixed to the upper crossbeam 1 and the lower crossbeam 2 through the flange 12.

[0043] Example 6

[0044] Based on the above embodiments, the reinforcing mechanism 6 of this embodiment includes two pressure plates 61, two support blocks 62, and a connecting block 63, as follows: Figure 2 As shown, two support blocks 62 are respectively located at the front and rear ends of the upper surface of the horizontal plate 10 of the upper beam 1, that is, at the two sides of the two side plates 9 that are close to each other. A connecting block 63 is installed through the center of the horizontal plate 10. The pressure plate 61 is T-shaped. The horizontal part of one pressure plate 61 is fixed on the two support blocks 62, and the other is located below the connecting block 63, and its horizontal part is connected to the connecting block 63. The clamping screw 4 passes through the upper pressure plate 61, the connecting block 63 and the lower pressure plate 61 in sequence from top to bottom, and is connected to the connecting block 63 and the two pressure plates 61 in a driving connection.

[0045] The reinforcement mechanism 6 in this embodiment can enhance the stability of the pressing screw 4 in pressing down or processing the workpiece, and can guide the pressing screw 4 during the movement of the pressing screw 4, so as to facilitate the movement of the pressing screw 4.

[0046] Example 7

[0047] Based on the above embodiments, in order to facilitate the rotation and movement of the clamping screw 4, a handwheel 13 is provided at the top of the clamping screw 4 in this embodiment. To avoid wear on the workpiece, a clamping plate 14 is threadedly connected to the bottom of this embodiment. The detachable configuration of the clamping plate 14 facilitates the selection of different sized clamping plates 14 according to the size of the workpiece, and also facilitates assembly or disassembly directly through the clamping screw 4 if necessary without using the clamping plate 14.

[0048] Example 8

[0049] Based on the above embodiments, in this embodiment, the outer ends of the base plate 7 and the upper support plate 8 are evenly connected by several telescopic mechanisms 15, such as... Figure 2 As shown, the telescopic mechanism 15 includes a guide sleeve 151 and a guide post 152. The outer diameter of the upper part of the guide post 152 is smaller than the outer diameter of the lower part. The upper part of the guide post 152 is slidably sleeved inside the guide sleeve 151. The bottom of the guide post 152 is connected to the base plate 7, and the top of the guide sleeve 151 is connected to the upper support plate 8.

[0050] For example Figure 1 In this design, the base plate 7 and the upper support plate 8 are square, so four telescopic mechanisms 15 are used to connect the four corners of the base plate 7 and the upper support plate 8 respectively. The telescopic mechanisms 15 facilitate the lifting of the workpiece by the lifting device 5 and enhance the connection stability between the upper support plate 8 and the base plate 7.

[0051] Example 9

[0052] Based on the above embodiments, the lifting device 5 in this embodiment is a jack. The base plate 7 is provided with a receiving groove 16 adapted to the lifting device 5, and the lifting device 5 is placed within the receiving groove 16. Figure 5As shown, when the lifting device 5 is a jack, the receiving groove 16 and the bottom of the jack are adapted.

[0053] The manual press based on this utility model can be used as follows: During assembly, for example, the inner component 17 is pressed into the outer component 18, the outer component is placed on the upper support plate 8, and after the inner component is placed above the outer component, the inner component is pressed downward into the outer component by the clamping screw 4, or the outer component is driven upward by the jack so that the inner component enters the outer component. Figure 6 As shown, assembly is completed using these steps. During disassembly, for example, to separate two bonded components, the workpiece is placed between the upper support plate 8 and the clamping screw 4. Disassembly is achieved by rotating the clamping screw 4 downwards or raising the lifting device 5, causing the two bonded components to displace in opposite directions. Figure 7 As shown.

[0054] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the concept and scope of the present utility model. Without departing from the design concept of the present utility model, all modifications and improvements made by those skilled in the art to the technical solutions of the present utility model should fall within the protection scope of the present utility model.
