Description

Technical Field

[0001] The present application relates to machining, and particularly to a cutting and positioning device. Background Art

[0002] The base of the steering main rod is a key connecting component. During the manufacturing process, a cutting separation opening needs to be made in the shaft hole on the base for passing through components. Traditional cutting methods often rely on the experience of operators and it is difficult to ensure the stability and accuracy of cutting. With the continuous progress of mechanical manufacturing technology, higher requirements are put forward for the precision and efficiency of cutting the shaft hole of the steering main rod base.

[0003] When cutting workpieces such as the base for fixing the steering main rod, the stability is insufficient, which easily causes the movement of the workpiece during the cutting process, thus affecting the cutting precision. Summary of the Invention

[0004] In order to improve the above problems, the present application provides a cutting and positioning device.

[0005] A cutting and positioning device provided by the present application adopts the following technical solution:

[0006] A cutting and positioning device includes a fixture frame and a pressing member; the fixture frame includes a first-layer frame body and a second-layer frame body; there is a placement opening for placing the workpiece between the first-layer frame body and the second-layer frame body, and a connecting frame is provided to connect the two; a positioning groove is opened on the first-layer frame body; the pressing member is installed on the top of the first-layer frame body, and the pressing end penetrates through the first-layer frame body and extends towards the second-layer frame body; the workpiece is located in the placement opening, and the workpiece is moved to make the point to be cut of the workpiece fit with the positioning groove, and the pressing end of the pressing member moves towards the second-layer frame body to fix the workpiece, and the cutting direction is to cut from top to bottom along the positioning groove.

[0007] By adopting the above technical solution, when it is necessary to cut the workpiece, the workpiece is placed on the second-layer frame body in the placement opening, and at the same time, the workpiece is moved along the second-layer frame body to make the point to be cut of the workpiece fit with the positioning groove. At this time, the cutting point position of the workpiece is positioned to ensure the accuracy of the cutting position. Subsequently, the pressing member is opened, and the pressing end of the pressing member moves towards the second-layer frame body to clamp and fix the workpiece in cooperation with the second-layer frame body, avoiding the deviation of the workpiece due to force during the cutting process. When cutting, the cutting device cuts from top to bottom along the positioning groove, thereby cutting the workpiece that is fixed and has a fixed cutting position.

[0008] Optionally, the first-layer frame body is further provided with a limiting groove; an adjusting portion is slidably connected in the limiting groove, and the adjusting portion is restricted in the limiting groove; the positioning groove is opened on the adjusting portion.

[0009] By adopting the above technical solution, the position of the positioning groove on the first frame body can be conveniently adjusted by moving the adjustment part along the limiting groove to adapt to workpieces of different sizes, thereby improving the versatility and flexibility of the positioning device.

[0010] Optionally, a threaded hole is provided on the adjusting portion; a screw-fastening portion is screwed into the threaded hole, and after the screw-fastening portion passes through the threaded hole, it abuts against the groove wall of the limiting groove.

[0011] By adopting the above technical solution, the screw-tightening part passes through the threaded hole and extends into the limiting groove. As the screw-tightening part continues to rotate, it presses against the groove wall of the limiting groove, and the adjusting part cannot be separated from the limiting groove, so that the adjusting part is pressed at this position and cannot move along the limiting groove, thereby achieving a positioning effect, making the position of the positioning groove fixed and difficult to shift, thereby further improving the cutting accuracy.

[0012] Optionally, the second frame body is provided with a cutting groove arranged opposite to the positioning groove of the first frame body.

[0013] By adopting the above technical solution, the purpose of setting the cutting groove is that when the cutting equipment is cutting the workpiece, the cutting point of the cutting equipment can penetrate the workpiece and extend into the cutting groove to ensure that the cutting point of the workpiece can be fully cut to avoid the situation where the workpiece is not cut at all.

[0014] Optionally, a slidable adapter is provided at the connecting frame, and the adapter abuts against the workpiece.

[0015] By adopting the above technical solution, the adapter can contact the workpiece when sliding along the connecting frame, so that when the workpiece moves to the positioning groove or the cutting groove, it can be close to the adapter to locate the placement position of the workpiece, which is convenient for positioning and cutting.

[0016] Optionally, the adapter includes an adapter portion and a contact portion; the adapter portion is threadedly connected to the connecting frame; and the contact portion is installed on the adapter portion and is located in the placement opening.

[0017] By adopting the above technical solution, the adapter part rotates along the screw joint, so that the adapter part drives the contact part to contact the workpiece, and then the position of the workpiece is recorded and located. When the next workpiece is cut, it can be directly moved to contact the contact part, that is, the positioning groove is aligned with the point to be cut, and no fine-tuning is required, thereby improving the convenience of precise adjustment.

[0018] Optionally, the second frame is also provided with scale marks.

[0019] By adopting the above technical solution, the placement position of the workpiece or the position where the contact part extends can be accurately understood by using the scale pattern, which not only ensures the accurate position of the cutting point of the workpiece, but also prevents the position of the contact part from shifting when it is used for too long.

[0020] Optionally, the cutting positioning device further includes a positioning light source, and the light irradiated by the positioning light source penetrates through the positioning groove and irradiates towards the second-layer frame or the workpiece.

[0021] By adopting the above technical solution, when the workpiece is located on the second-layer frame, the light of the positioning light source is located on the workpiece, so as to more accurately ensure the accuracy of the cutting point.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. When it is necessary to cut the workpiece, place the workpiece on the second-layer frame in the placement opening, and at the same time move the workpiece along the second-layer frame so that the cutting point to be cut of the workpiece fits the positioning groove. At this time, the cutting point position of the workpiece is located, ensuring the accuracy of the cutting position. Then, open the pressing part, and the pressing end of the pressing part moves towards the second-layer frame to clamp and fix the workpiece in cooperation with the second-layer frame, avoiding the workpiece from shifting under force during the cutting process. When cutting, the cutting device cuts from top to bottom through the positioning groove, so as to cut the workpiece that is fixed and has a fixed cutting position;

[0025] 3. The function of setting the cutting groove is that when the cutting device cuts the workpiece, the cutting point of the cutting device can penetrate the workpiece and extend into the cutting groove to ensure that the cutting point of the workpiece can be fully cut open, avoiding the situation of not being cut open at all;

[0026] 4. The adapting part rotates along the screw connection point, so that the adapting part drives the contact part to contact the workpiece. Subsequently, the position of the workpiece is recorded and located. When the next workpiece is cut, it can be directly moved to contact the contact part, that is, the positioning groove is aligned with the cutting point to be cut, without further fine adjustment, improving the convenience of precise adjustment.

[0037] The following will further describe the present application in detail with reference to the Figure 1 - attached Figure 4 drawings.

[0038] An embodiment of the present application discloses a cutting positioning device.

[0039] A cutting positioning device, as shown in the reference Figure 1 , includes a fixture frame 1 and a pressing member 2; the fixture frame 1 includes a first layer frame body 11 and a second layer frame body 12; there is a placement opening for placing a workpiece between the first layer frame body 11 and the second layer frame body 12, and the two are connected by a connecting frame 13. In this embodiment, the workpiece can be the base of a steering main rod, and a shaft hole for a shaft or rod to pass through is provided on the base. It is necessary to cut open the shaft hole to penetrate the shaft or rod, and then fasten it with a fastening screw to facilitate the overall disassembly and assembly. After the first layer frame body 11 and the second layer frame body 12 are connected by the connecting frame 13, the gap between the two is the space for placing the workpiece, that is, the placement opening. The workpiece can be placed on the second layer frame body 12 for cutting.

[0040] A positioning groove 111 is provided on the first layer frame body 11, and an external cutting machine can perform cutting along the positioning groove 111, and several positioning grooves 111 can be provided.

[0041] The pressing member 2 is installed on the top of the first layer frame body 11, and the pressing end penetrates the first layer frame body 11 and extends towards the second layer frame body 12. The pressing member 2 can be any power element such as a cylinder, an electric push rod, or an oil cylinder. When the pressing end penetrates the first layer frame body 11 and moves towards the second layer frame body 12, it can cooperate with the second layer frame body 12 to clamp and fix the workpiece.

[0042] Specifically, when it is necessary to cut the workpiece, place the workpiece on the second layer frame body 12 in the placement opening, and at the same time move the workpiece along the second layer frame body 12 to make the cutting point of the workpiece fit the positioning groove 111. At this time, the cutting point position of the workpiece is positioned to ensure the accuracy of the cutting position. Then, open the pressing member 2, and the pressing end of the pressing member 2 moves towards the second layer frame body 12 to cooperate with the second layer frame body 12 to clamp and fix the workpiece, avoiding the workpiece from shifting under force during the cutting process. When cutting, the cutting device cuts from top to bottom along the positioning groove 111, so as to cut the fixed workpiece with an accurate cutting position.

[0043] In some embodiments, as shown in the referenceFigure 2 As shown, the first-layer frame body 11 is further provided with a limiting groove 112, and the limiting groove 112 can be any special-shaped groove such as a T-shaped groove or an I-shaped groove.

[0044] A regulating part 113 is slidably connected in the limiting groove 112, and the regulating part 113 is restricted in the limiting groove 112. A positioning groove 111 is formed on the regulating part 113. The regulating part 113 can be a sliding block, and the positioning groove 111 is formed on the sliding block. When the sliding block moves along the limiting groove 112, the position of the positioning groove 111 on the first-layer frame body 11 can be conveniently adjusted to adapt to workpieces of different sizes, improving the versatility and flexibility of the positioning device.

[0045] Furthermore, a threaded hole is formed on the regulating part 113, and a tightening part 114 is screwed in the threaded hole. After the tightening part 114 penetrates through the threaded hole, it abuts against the groove wall of the limiting groove 112. The tightening part 114 can be a bolt. By using the bolt to penetrate through the threaded hole and extend into the limiting groove 112, as the bolt continues to rotate, it abuts tightly against the groove wall of the limiting groove 112, and the regulating part 113 cannot break away from the limiting groove 112, so that the regulating part 113 is tightened at this position and cannot move along the limiting groove 112, thus achieving the positioning effect, making the position of the positioning groove 111 fixed and difficult to shift, and further improving the cutting accuracy.

[0046] Among them, the screwing part is a wing bolt, and the wing bolt can provide a convenient fulcrum for rotation, facilitating the loosening and tightening of the regulating part 113.

[0047] In another embodiment, as shown in Figure 3 a cutting groove 121 is formed on the second-layer frame body 12 and is arranged opposite to the positioning groove 111 of the first-layer frame body 11, that is, the positioning groove 111 and the cutting groove 121 are located on the same vertical straight line, and the vertical extension line of the positioning groove 111 can penetrate through the cutting groove 121. The function of setting the cutting groove 121 is that when the cutting equipment cuts the workpiece, the cutting point of the cutting equipment can penetrate the workpiece and extend into the cutting groove 121 to ensure that the cutting point of the workpiece can be fully cut and avoid the situation of not being cut at all.

[0048] Furthermore, as shown in Figure 3 a slidable adapter 14 is arranged at the connecting frame 13. The adapter 14 abuts against the workpiece. When the adapter 14 slides along the connecting frame 13, it can contact the workpiece, so that when the workpiece moves to the positioning groove 111 or the cutting groove 121, it can be close to the adapter 14 to position the placement position of the workpiece and facilitate positioning and cutting.

[0049] Specifically, after determining the position of the workpiece to be cut, the workpiece moves along the second-layer frame 12, so that the position to be cut fits with the cutting groove 121 and the positioning groove 111. At this time, the adapter 14 is slid to the position in contact with the workpiece, and then the pressing member 2 can be activated to fix the workpiece and perform cutting. When subsequent workpieces are cut, there is no need to adjust the position of the workpiece again to align the position to be cut with the positioning groove 111. The workpiece is directly moved to be in close contact with the adapter 14, which means that the position to be cut is aligned with the positioning groove 111, improving the convenience of positioning.

[0050] Furthermore, the adapter 14 includes an adaptation portion 131 and a contact portion 132; the adaptation portion 131 is screwed to the connecting frame 13. The adaptation portion 131 can be a screw rod, and screw holes can be provided on the connecting frame 13, so that the screw rod can rotate along the screw holes and extend to the workpiece. The contact portion 132 is installed on the adaptation portion 131 and is located within the placement opening. The contact portion 132 can be made of a rubber plate or a plastic plate, which has a certain elasticity and can avoid rigid contact with the workpiece during cutting and damage the workpiece.

[0051] Among them, the connection method between the contact portion 132 and the adaptation portion 131 can be a movable connection. Specifically, a pivot groove is provided at one end of the contact portion 132, and the contact portion 132 pivots with the adaptation portion 131 using the pivot groove. When the contact portion 132 contacts the workpiece, the adaptation portion 131 can continue to rotate, while the contact portion 132 can be subject to the frictional force of the workpiece and does not rotate with the adaptation portion 131, which can prevent the workpiece from being scratched by the contact portion 132.

[0052] Specifically, the adaptation portion 131 rotates along the screw connection point, so that the adaptation portion 131 drives the contact portion 132 to contact the workpiece. Subsequently, the position of the workpiece is recorded and positioned. When the next workpiece is cut, it can be directly moved to contact the contact portion 132, that is, at the alignment point of the positioning groove 111 and the point to be cut, without the need for further fine adjustment, improving the convenience of precise adjustment.

[0053] In some embodiments, scale lines are also provided on the second-layer frame 12. Using the scale lines, the placement position of the workpiece or the position where the contact portion 132 extends can be accurately understood, which not only ensures the accuracy of the cutting point position of the workpiece but also can prevent the position of the contact portion 132 from shifting when it is used for too long.

[0054] In some embodiments, referring to Figure 4 As shown, the cutting positioning device further includes a positioning light source 3. The light irradiated by the positioning light source 3 passes through the positioning groove 111 and irradiates towards the second-layer frame 12 or the workpiece. When the workpiece is on the second-layer frame 12, the light of the positioning light source 3 is on the workpiece, so as to more accurately ensure the accuracy of the cutting point.

[0055] The positioning light source 3 can be an LED lamp, and the color of the LED lamp can be determined according to requirements, such as red, green, etc.

[0056] Among them, if the adjusting part 113 is provided, the positioning light source 3 is installed on the adjusting part 113, so that when the adjusting part 113 moves along the limiting groove 112, the positioning light source 3 moves with the adjusting part 113 to ensure that the light of the positioning light source 3 can accurately pass through the positioning groove 111 to the surface of the workpiece (not shown in the figure).

[0057] Among them, when a plurality of cutting grooves 121 are provided, the positions of the positioning groove 111 and the cutting groove 121 are fixed, then the positioning light source 3 can be provided on the first layer frame 11 or the pressing part 2, and the positioning light source 3 can directly irradiate the cutting groove 121 from the positioning groove 111.

[0058] The embodiments of the specific implementation manners are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. The same components are denoted by the same reference numerals. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
