[0001] This utility model relates to the field of press technology, specifically to a high-precision manual press. Background Technology

[0002] Manual presses are mainly used for disassembling tight parts such as gears and bushings, as well as correcting deformed parts. When selecting a press, it is best to choose a multi-functional machine. Different presses are used depending on the diameter of the workpiece being corrected. With societal development, manual presses are used when parts require machining. In the manufacturing process of flat wire motors, after the flat wire is wound, there is a wire insertion process, which requires a press to perform the wire pressing operation.

Utility Model Content

[0005] The present invention aims to overcome the defects in the prior art and provide a manual press that can effectively control the pressing distance and improve the pressing accuracy.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a manual press, comprising a support frame and a pressing mechanism disposed on the support frame, wherein the support frame is provided with an adjusting component for adjusting the height of the pressing mechanism, the adjusting component comprising a lifting column for connecting the pressing mechanism and a fixing component for fixing the lifting position of the pressing mechanism; the pressing mechanism comprises a cantilever connected to the lifting column and a pressing column disposed on the cantilever, the pressing column being provided with a plurality of lifting teeth, the cantilever being provided with a gear meshing with the lifting teeth, and a handle for driving the gear to rotate being connected to the gear.

[0007] As a preferred embodiment of this utility model, the connection end of the cantilever and the lower pressure column is provided with a through hole for the lower pressure column to pass through, and the cantilever is provided with a gear groove that communicates with the through hole, and the gear is rotatably disposed in the gear groove.

[0008] As a preferred embodiment of this utility model, the gear is provided with a gear shaft that drives the gear to rotate. One end of the gear shaft is connected to the bottom end of the handle. The cantilever is provided with a shaft hole along the width direction of the cantilever, and the gear shaft is located in the shaft hole.

[0009] As a preferred embodiment of this utility model, the cantilever is provided with a guide column, the guide column is provided with a sliding sleeve, the two ends of the guide column are provided with limiting members for lifting and limiting the sliding sleeve, and the top of the pressing column is provided with a connecting member connected to the sliding sleeve.

[0010] As a preferred embodiment of this utility model, the lower pressure column is provided with a spring for lifting and resetting the lower pressure column, and the two ends of the spring abut against the cantilever and the connecting member respectively.

[0011] As a preferred embodiment of this utility model, a guide shaft is provided on one side of the lifting column, and the fixing component is slidably connected to the guide shaft.

[0012] As a preferred embodiment of this utility model, the connection end of the cantilever and the lifting column is provided with a fixing hole for connecting the lifting column, and fixing grooves are provided on both sides of the fixing hole along the length direction of the cantilever, and bolts for tightening the fixing grooves are provided on the fixing component.

[0013] As a preferred embodiment of the present invention, the adjustment assembly further includes a mounting base for fixing the lifting column and the guide shaft, and a connecting plate for connecting the guide shaft is provided at the top of the lifting column.

[0014] As a preferred embodiment of this utility model, the bottom end of the lower pressure column is provided with a pressure line structure. The pressure line structure includes a base and pressure blocks respectively disposed at both ends of the base. A first pressure plate and a second pressure plate are disposed between the two pressure blocks. The base is provided with a fixing pin for fixing the first pressure plate and the second pressure plate.

[0015] In a preferred embodiment of this utility model, both the first pressing plate and the second pressing plate are arranged perpendicularly to the pressing block, and the first pressing plate is located on both sides of the second pressing plate. The length of the second pressing plate is greater than that of the first pressing plate, and both ends of the first pressing plate and the second pressing plate are set as arc-shaped structures.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The overall height of the pressing mechanism is adjusted by the set adjustment components to adapt to the pressing height of the flat wire motor, thereby reducing the lifting distance of the pressing mechanism. At the same time, by setting lifting teeth on the pressing column and setting gears to mesh with the lifting teeth, a handle is connected to the gear to control the rotation of the gear. The handle drives the gear to rotate, thereby driving the pressing column to rise and fall, thereby achieving precise control of the pressing distance of the pressing column, improving the pressing accuracy, and thus meeting the high precision requirements of the flat wire motor insertion process.

[0018] 2. Furthermore, limiters are provided at both ends of the guide column. The pressing column is connected to the sliding sleeve of the guide column through the connector and moves up and down between the two limiters, thereby limiting the lifting distance of the pressing column and thus avoiding damage to the flat wire due to excessive descent distance.

[0019] 3. Furthermore, a spring is installed on the lower pressure column. When the lower pressure column descends and completes the wire pressing, the spring is in a compressed state. Releasing the handle causes the lower pressure column to automatically reset under the action of the spring, thereby allowing it to enter the next wire insertion position more quickly and improving the wire pressing efficiency.

[0020] 4. Furthermore, by sliding the fixing component onto the guide shaft, the lifting and lowering of the cantilever is guided. And by tightening the fixing groove at the end of the cantilever by passing bolts through the fixing component, the cantilever is fixed to the lifting column, ensuring that the height of the pressing mechanism does not change during the pressing process. At the same time, the cooperation between the fixing component, the guide shaft, and the lifting column restricts the horizontal degree of freedom of the pressing mechanism, ensuring that the cantilever does not rotate horizontally, thereby improving the stability of the pressing mechanism in pressing the line.

Detailed Implementation

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1-3 As shown, a manual press includes a support frame 1 and a pressing mechanism 2 mounted on the support frame 1. The support frame 1 is provided with an adjusting component 3 for adjusting the height of the pressing mechanism 2. The adjusting component 3 includes a lifting column 303 for connecting the pressing mechanism 2 and a fixing member 302 for fixing the lifting position of the pressing mechanism 2. The pressing mechanism 2 includes a cantilever 201 connected to the lifting column 303 and a pressing column 202 mounted on the cantilever 201. The pressing column 202 is provided with a plurality of lifting teeth 2021. The cantilever 201 is provided with a gear 203 that meshes with the lifting teeth 2021. A handle 204 that drives the gear 203 to rotate is connected to the gear 203.

[0027] Furthermore, the support frame 1 is fixed to the ground or workbench with bolts to ensure the stability of the press during the pressing process. The adjustment component 3 is set on one side of the support frame 1 and is set along the height direction of the support frame 1. The cantilever 201 of the pressing mechanism 2 is connected to the lifting column 303 of the adjustment component 3. The pressing mechanism 2 can be adjusted along the height direction of the lifting column 303 and fixed by the fixing component 302, thereby adapting to the pressing height of the flat wire motor and reducing the lifting distance of the pressing mechanism 2. At the same time, by setting the lifting gear 2021 on the pressing column 202 and setting the gear 203 to mesh with the lifting gear 2021, the gear 203 is connected to the handle 204 to control the rotation of the gear 203. The handle 204 drives the gear 203 to rotate, thereby driving the pressing column 202 to rise and fall, thereby achieving precise control of the pressing distance of the pressing column 202, improving the pressing accuracy, and thus meeting the high precision requirements of the flat wire motor insertion process.

[0028] The cantilever 201 and the lower pressure column 202 are connected at the end of the cantilever 201 with a through hole 2013 for the lower pressure column 202 to pass through. The cantilever 201 is provided with a gear groove 2015 that communicates with the through hole 2013. The gear 203 is rotatably disposed in the gear groove 2015. Furthermore, the diameter of the through hole 2013 is larger than the diameter of the lower pressure column 202. The lower pressure column 202 is disposed in the through hole 2013 and moves up and down in the through hole 2013. The through hole 2013 is located at the end of the cantilever 201, that is, the connection end between the cantilever 201 and the lower pressure column 202, specifically at the end away from the adjustment component 3. The gear groove 2015 is disposed along the length direction of the cantilever 201 and is disposed on one side of the through hole 2013 and communicates with the through hole 2013. The gear 203 is rotatably disposed in the gear groove 2015 and meshes with several lifting teeth 2021 on the lower pressure column 202 in the gear groove 2015.

[0029] The gear 203 is provided with a gear shaft 2031 that drives the gear 203 to rotate. One end of the gear shaft 2031 is connected to the bottom end of the handle 204. The cantilever 201 is provided with a shaft hole 2014 along the width direction of the cantilever 201. The gear shaft 2031 is located in the shaft hole 2014. Furthermore, the shaft hole 2014 is provided at the gear groove 2015 and passes through the cantilever 201. The axial direction of the shaft hole 2014 is perpendicular to the axial direction of the through hole 2013. The gear shaft 2031 is connected in the shaft hole 2014, and one end of the gear shaft 2031 extends out from the shaft hole 2014 and is connected to the handle 204. By pressing the handle 204 downward, the gear shaft 2031 and the gear 203 rotate synchronously, thereby driving the lower pressure column 202 to move downward, thereby realizing the wire pressing operation.

[0030] A guide post 205 is provided on the cantilever 201, and a sliding sleeve 2051 is provided on the guide post 205. Limiting members 2052 for limiting the lifting and lowering of the sliding sleeve 2051 are provided at both ends of the guide post 205. A connecting member 2022 for connecting to the sliding sleeve 2051 is provided at the top of the pressing post 202. Furthermore, the guide post 205 is located at the end of the cantilever 201, and the guide post 205 and the pressing post 202 are located at the same end of the cantilever 201, and are arranged parallel to each other. The sliding sleeve 2051 is sleeved on the guide post 205, and can rise and fall on the guide post 205. Limiting members 2052 for limiting the lifting and lowering of the sliding sleeve 2051 are provided at both ends of the guide post 205. A limiting component 2052 is used to limit the lifting distance of the sliding sleeve 2051. A connecting component 2022 is provided on the top of the pressing column 202. The connecting component 2022 is fixedly connected to the top of the sliding sleeve 2051. The pressing column 202 and the sliding sleeve 2051 are connected through the connecting component 2022. The pressing column 202 and the sliding sleeve 2051 lift synchronously, thereby connecting the pressing column 202 with the guide column 205. The guide column 205 guides the lifting of the pressing column 202. At the same time, the limiting component 2052 limits the lifting distance of the pressing column 202, thereby preventing damage to the flat wire due to excessive descent distance.

[0031] The lower pressure column 202 is equipped with a spring 206 for lifting and resetting the lower pressure column 202. The two ends of the spring 206 abut against the cantilever 201 and the connector 2022 respectively. Furthermore, the spring 206 is sleeved on the lower pressure column 202. When the lower pressure column 202 descends and completes the wire pressing, the spring 206 is in a compressed state. Releasing the handle 204 causes the lower pressure column 202 to automatically reset under the action of the spring 206, thereby more quickly entering the next wire insertion position for wire pressing and improving the wire pressing efficiency.

[0032] A guide shaft 301 is provided on one side of the lifting column 303, and a fixing member 302 is slidably connected to the guide shaft 301. Furthermore, the guide shaft 301 is arranged parallel to the lifting column 303, and the fixing member 302 is slidably arranged on the guide shaft 301. The fixing member 302 can be a linear bearing. The fixing member 302 is connected to the cantilever 201, and the lifting and lowering guidance of the cantilever 201 is realized through the guide shaft 301.

[0033] The connecting end of the cantilever 201 and the lifting column 303 is provided with a fixing hole 2011 for connecting the lifting column 303. Fixing grooves 2012 are provided on both sides of the fixing hole 2011 along the length direction of the cantilever 201. The fixing member 302 is provided with bolts 3021 for tightening the fixing grooves 2012. Furthermore, the diameter of the fixing hole 2011 is adapted to the diameter of the lifting column 303. The lifting column 303 is connected in the fixing hole 2011. The fixing grooves 2012 are arranged along the length direction of the cantilever 201, and are located on opposite sides of the fixing hole 2011. The cantilever 201 has bolt holes on its side that pass through the fixing groove 2012. Bolts 3021 pass through the fixing member 302 and are connected to the bolt holes. By tightening the bolts 3021, the fixing groove 2012 is tightened, thereby fixing the cantilever 201 to the lifting column 303. This ensures that the height of the pressing mechanism 2 does not change during the pressing process. At the same time, the cooperation between the fixing member 302, the guide shaft 301, and the lifting column 303 restricts the horizontal degree of freedom of the pressing mechanism 2, ensuring that the cantilever 201 will not rotate horizontally, thereby improving the stability of the pressing mechanism 2 in pressing the line.

[0034] The adjustment assembly 3 also includes a mounting base 304 for fixing the lifting column 303 and the guide shaft 301. The top of the lifting column 303 is provided with a connecting plate 3031 for connecting the guide shaft 301. Furthermore, the mounting base 304 is set on the support frame 1, and the lifting column 303 and the guide shaft 301 are mounted on the mounting base 304. The connecting plate 3031 is provided on the top of the lifting column 303 and is connected to the top of the guide shaft 301. The lifting column 303 and the guide shaft 301 are connected through the connecting plate 3031, thereby ensuring the stability between the lifting column 303 and the guide shaft 301.

[0035] The bottom end of the lower pressure column 202 is provided with a pressure wire structure 4. The pressure wire structure 4 includes a base 401 and pressure blocks 402 respectively disposed at both ends of the base 401. A first pressure plate 403 and a second pressure plate 404 are disposed between the two pressure blocks 402. The base 401 is provided with fixing pins 405 for fixing the first pressure plate 403 and the second pressure plate 404. Furthermore, the base 401 is connected to the bottom end of the lower pressure column 202, and pressure blocks are respectively connected to both ends of the base 401. 402, the bottom end of the pressure block 402 is a concave arc-shaped structure. When pressing the line, the pressure block 402 abuts against the tooling, and the arc-shaped structure of the pressure block 402 is adapted to the tooling. A first pressure plate 403 and a second pressure plate 404 are connected to the lower surface of the base 401. The first pressure plate 403 and the second pressure plate 404 are both inserted into the base 401, and a fixing pin 405 for fixing the first pressure plate 403 and the second pressure plate 404 is provided on the base 401.

[0036] The first pressing plate 403 and the second pressing plate 404 are both perpendicular to the pressing block 402, with the first pressing plate 403 located on both sides of the second pressing plate 404. The second pressing plate 404 is longer than the first pressing plate 403. Both ends of the first pressing plate 403 and the second pressing plate 404 are set with arc-shaped structures. Furthermore, the first pressing plate 403 and the second pressing plate 404 are both arranged along the length direction of the base 401, that is, the first pressing plate 403 and the second pressing plate 404 are perpendicular to the surface of the pressing block 402, and the first pressing plate 403 and the second pressing plate 404 are arranged parallel to each other. The first pressing plate 403 is provided with... Two first pressing plates 403 are located on opposite sides of a second pressing plate 404. The length of the second pressing plate 404 is greater than the length of the first pressing plate 403, meaning that both ends of the second pressing plate 404 are longer than the first pressing plate 403. The pressing operation is achieved through the first pressing plate 403 and the second pressing plate 404, and the longer second pressing plate 404 is used to squeeze the flat line at the edge, thus providing the pressing effect. In addition, both ends of the first pressing plate 403 and the second pressing plate 404 are arc-shaped structures. The arc-shaped structure is designed to avoid damaging the flat line during pressing.
