Description

Technical Field

[0001] The utility model belongs to the technical field of fixed tooling, and more specifically, relates to a fixed tooling for an idler wheel automatic punching machine. Background Art

[0002] In mechanical equipment, wheels that mainly use their inertia are collectively called idlers. In a gear train, if a gear is both a driven wheel of the previous stage transmission and a driving wheel of the next stage transmission, then this gear is called an idler. Before using the idler, it is necessary to punch holes in the idler, but the existing fixed clamping equipment has poor use effect. The patent (publication number: CN216420799U) discloses an automatic punching machine for idlers. This punching machine controls several bidirectional screws and screws manually, thereby realizing the control of several bidirectional screws and several clamping plates correspondingly fixed on the screws, and then realizes the fixation of the idler by squeezing several clamping plates, and finally realizes the punching of the idler. When this punching machine is used, when the position of the idler needs to be changed, all bidirectional screws and screws need to be manually adjusted, which is inefficient, and the adjustment accuracy is low, and the use effect is poor. When punching holes in the idler, it is not easy to perform real-time displacement of the idler, and the idler position may be inaccurate, resulting in the punched hole not meeting the standard, which greatly affects the later use effect of the idler.

[0028] The fixing assembly includes a third fixing bolt 202 . The slide rail 2 is provided with a threaded through hole adapted to the third fixing bolt 202 . The threaded through holes penetrate the bottom and the top of the slide rail 2 respectively.

[0029] The third fixing bolt 202 passes through the bottom and top of the slide rail 2 through the threaded through holes arranged on the slide rail 2 . The third fixing bolt 202 is screwed into the top of the workbench 6 to preliminarily fix the slide rail 2 on the workbench 6 .

[0030] The fixing assembly includes a fixing plate 204, which has two fixing plates 204 and is parallel to each other and arranged at intervals. The fixing plate 204 is arranged perpendicular to the workbench 6, and the bottom of the fixing plate 204 is fixedly connected to the top of the workbench 6. The length of the fixing plate 204 is the same as the length of the slide rail 2, and the width of the fixing plate 204 is the same as the height of the slide rail 2. The two fixing plates 204 are tightly fitted on the two sides of the slide rail 2 and are arranged along the length direction of the slide rail 2.

[0031] A second fixing bolt 203 is provided on the side of the fixing plate 204 away from the slide rail 2. The second fixing bolt 203 is arranged perpendicular to the fixing plate 204. A threaded through hole matched with the second fixing bolt 203 is provided on the fixing plate 204. The threaded through hole passes through the front and rear sides of the fixing plate 204 respectively.

[0032] The second fixing bolt 203 passes through the front and rear sides of the fixing plate 204 through the threaded through holes arranged on the fixing plate 204. The second fixing bolt 203 is screwed into the left and right sides of the slide rail 2. The slide rail 2 is further fixed on the workbench 6 through the action of the fixing plate 204 and the second fixing bolt 203.

[0033] The bottom of both end surfaces of the slide rail 2 is fixedly connected to the top of the workbench 6 by welding.

[0034] With such a design, during operation, the slide rail 2 is firmly fixed on the workbench 6 through the action of the third fixing bolt 202, the second fixing bolt 203 and the fixing plate 204, which is convenient to use and has a significant effect.

[0035] The slide rail 2 is provided with a slideway 201 , which is opened along the length direction of the slide rail 2 and passes through the front and rear end surfaces of the slide rail 2 .

[0036] The slide 201 is provided with two chambers, namely a first chamber 2011 located at the lower part of the slide 201, and a second chamber 2012 located at the upper part of the slide 201. The width of the first chamber 2011 is greater than the width of the second chamber 2012. The first chamber 2011 and the second chamber 2012 together constitute the slide 201 for sliding.

[0037] There are three slideways 201 , and the three slideways 201 are arranged in parallel and at intervals along the width direction of the slide rail 2 .

[0038] In this embodiment, there are multiple third fixing bolts 202 and multiple second fixing bolts 203 , and there are multiple threaded through holes matching the third fixing bolts 202 and the second fixing bolts 203 .

[0039] The support mechanism includes a support plate 304 , one end of the support plate 304 is fixedly connected to the bottom of the clamping body 3 , and the other end of the support plate 304 extends in a direction away from the clamping body 3 .

[0040] The two support plates 304 form a group, and the two support plates 304 are arranged axially symmetrically along the line connecting the midpoints of the two short sides of the bottom surface of the clamping body 3. There are three groups of support plates 304 in total, and the three groups of support plates 304 are parallel to each other and arranged at intervals at the bottom of the clamping body 3 along the length direction of the bottom surface of the clamping body 3.

[0041] This design makes the bottom area of ​​the clamping body 3 larger, and the clamping body 3 has greater stability when sliding on the slide 201. When fixation is required, the support plate 304 can also increase the stability of the clamping body 3 on the slide 201.

[0042] The support mechanism further includes a support bolt 303 , which is slidably disposed on the slideway 201 . The support bolt 303 is vertically arranged on the slideway 201 , and one end of the support bolt 303 away from the slideway 201 vertically penetrates the bottom and top of the clamping body 3 .

[0043] The supporting bolt 303 includes a supporting threaded column 3031 .

[0044] The clamping body 3 is provided with threaded through holes, which respectively penetrate the bottom and the top of the clamping body 3 , and the supporting threaded column 3031 is screwed into and passes through the clamping body 3 through the threaded through holes.

[0045] The support bolt 303 further includes a cylindrical slider 3032 , and the cylindrical slider 3032 is disposed in the first chamber 2011 .

[0046] The cylindrical slider 3032 is a cylinder, and the upper end surface of the cylindrical slider 3032 is integrally connected with the lower end surface of the supporting threaded column 3031 .

[0047] The end surface diameter of the cylindrical slider 3032 is smaller than the width of the first chamber 2011 , the end surface diameter of the cylindrical slider 3032 is larger than the width of the second chamber 2012 , and the height of the cylindrical slider 3032 is smaller than the height of the first chamber 2011 .

[0048] The end surface diameter of the supporting threaded column 3031 is smaller than the width of the second chamber 2012 .

[0049] In this embodiment, the number of the supporting bolts 303 is two, and the two supporting bolts 303 are parallel to each other and arranged on the clamping body 3 at intervals.

[0050] With this design, the clamping body 3 is pushed, and the support bolts 303 on the clamping body 3 cooperate with the slide 201 to enable the clamping body 3 to move back and forth on the slide 201 along the length direction of the slide 2. The three groups of support plates 304 make the sliding action more stable. After adjusting to the appropriate position, tighten the support bolts 303 upwards. At this time, the cylindrical slider 3032 on the support bolts 303 squeezes the inner wall of the first chamber 2011 upwards, and the clamping body 3 is firmly fixed on the slide 201 through the force of the support bolts 303 on the clamping body 3 and the reaction force of the clamping body 3 on the support bolts 303, so that it no longer moves.

[0051] A driving mechanism 4 is disposed on one side of the workbench 6 , and an output end of the driving mechanism 4 is transmission-connected to the workbench 6 .

[0052] During operation, the driving mechanism 4 drives the workbench 6 to move on the base 1, the workbench 6 drives the slide rail 2 to move, and the slide rail 2 drives the clamping body 3 to move through the support bolt 303, and the clamping body 3 moves towards or away from the drill bit.

[0053] The clamping hole 301 is adapted to the size of the idler wheel.

[0054] The axial direction of the fixing threaded hole 305 is perpendicular to the axial direction of the clamping hole 301 .

[0055] With such a design, when in use, the idler wheel is placed in the clamping hole 301, and the first fixing bolt 302 is tightened so that the first fixing bolt 302 passes through the fixing threaded hole 305 and enters the clamping hole 301, and then the first fixing bolt 302 cooperates with the inner wall of the clamping hole 301 to fix the idler wheel in the clamping hole 301.

[0056] A cooling mechanism 5 is also provided on one side of the clamping body 3 , and an output end of the cooling mechanism 5 is close to a clamping hole 301 on the clamping body 3 .

[0057] With this design, when the electric drill is used to drill a hole in the idler wheel, the temperature at the joint is too high, which may cause local deformation. The cooling mechanism 5 is used to cool it, which is convenient to use.

[0058] During operation, the idler wheel is first fixed to the clamping hole 301 by the cooperation between the first fixing bolt 302 and the inner wall of the clamping hole 301, and then the clamping body 3 is moved back and forth on the slide rail 201 along the length direction of the slide rail 2 by the cooperation between the supporting bolt 303 on the clamping body 3 and the slideway 201 to find a suitable punching position. After the length direction is determined, the supporting bolt 303 is tightened upwards, and the clamping body 3 is firmly fixed to the slideway 201 through the force of the supporting bolt 303 on the clamping body 3 and the reaction force of the clamping body 3 on the supporting bolt 303. The position of the electric drill bit is preliminarily determined, and then the driving mechanism 4 drives the workbench 6, the workbench 6 drives the slide rail 2, and the slide rail 2 drives the clamping body 3 to move toward or away from the drill bit. The limit bar 101 limits the movement trajectory of the workbench 6 to further determine the position of the clamping body 3 relative to the electric drill bit. After determining the position, the electric drill drills a hole in the idler wheel. During the drilling process, the idler wheel is cooled in real time by using the cooling mechanism 5. When the idler wheel position needs to be adjusted, the position of the idler wheel can be accurately and quickly adjusted by adjusting the support mechanism and the driving mechanism 4.

[0059] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
