Description

Technical Field

[0001] The utility model relates to the field of clamping and positioning of rail vehicle profiles, in particular to a clamping and positioning device for cutting rail vehicle profiles. Background Art

[0002] The clamping and positioning device for rail vehicle profile cutting is a tool specially used in the profile cutting process in rail vehicle manufacturing and maintenance. The main purpose of this device is to ensure that the profile is accurately fixed and positioned during the cutting process to ensure the accuracy and quality of the cutting. The core function of the clamping and positioning device is to ensure that the profile is firmly clamped during the cutting process to prevent movement or vibration during the cutting process, thereby improving the accuracy of the cutting. The device can position the profile to a precise position to meet the requirements of cutting size and angle, and avoid cutting errors caused by inaccurate positioning. Its design and operation need to take into account accuracy, repeatability and safety to meet the high standards required in rail vehicle manufacturing and maintenance.

[0003] In the specific cutting, clamping and positioning of rail vehicle profiles, the usual devices use clamps to limit the profiles during processing. After the limiting is completed, the profiles are cut using a cutting machine. Although this method can cut the profiles, the limiting effect is not comprehensive, which will affect the subsequent processing of the profiles. In addition, when cutting the profiles, iron slag and debris may be generated, which is not convenient for the operator to clean. Utility Model Content

When moving, since the height of the limit bar 18 is lower than the height of the cutting blade 22, the limit bar 18 can position the top of the two sides of the profile through the action of the spring 16. Through the continuous movement of the hydraulic cylinder 12, when the cutting blade 22 moves to contact the profile, the operator can first start the two groups of hydraulic cylinders 12 to move toward each other, so as to clamp the two sides of the profile, and start the motor 21 to drive the cutting blade 22 to rotate, so that the profile can be cut. Then, when the operator is cutting the profile, the profile can be fully clamped and positioned, which will not affect the subsequent processing of the profile and improve the processing efficiency of the profile.

[0027] Reference Figure 1-Figure 4In a preferred embodiment, a mounting bracket 2 is provided at one end of the fixed shaft 13, a motor 21 is provided on one side of the mounting bracket 2, a spring 16 is provided on the surface of the telescopic rod 15, the spring 16 is provided between the limit bar 18 and the fixed plate 14, a processing table 29 is provided on the top of the fixed bracket 25, a cutting blade 22 is provided at the output end of the motor 21, the cutting blade 22 is provided just above the processing table 29, a mounting hole is provided inside the limit bar 18, a hydraulic rod 17 is inserted inside the mounting hole, and anti-slip pads 23 are provided on the opposite ends of the two sets of clamping blocks 19. By providing the anti-slip pads 23, the limiting effect of the clamping blocks 19 can be improved. 2. The blower 3, the processing table 29 and the drawer 27 cooperate with each other, so that when the operator needs to clean the iron slag debris and the like generated by the profile, the operator can first use the cutting blade 22 to cut the profile. When cutting, the operator can start the blower 3 to blow the iron slag debris and the like generated by the profile on the top of the processing table 29. At this time, since one side of the processing table 29 is set in an inclined shape, the iron slag debris and the like can be blown into the inside of the drawer 27. When the profile processing is completed, the operator processes the iron slag debris and the like in the drawer 27, so that the iron slag debris and the like generated by the iron slag debris and the like can be centrally processed, which is convenient for the operator to use.

[0028] Reference Figure 1-Figure 4 In a preferred embodiment, a limit frame 32 is provided on the top of the mounting plate 11, and the hydraulic cylinder 12 is arranged inside the limit frame 32. One side of the processing table 29 is arranged in an inclined shape. A groove is provided on the top of the fixed frame 25, and a slide rail is provided inside the groove. A drawer 27 slides on the surface of the slide rail. By providing the drawer 27, iron slag debris can be collected. A handle 28 is provided on one side of the drawer 27. By providing the handle 28, it is convenient for the operator to pull the drawer 27. A mounting groove is provided inside the fixed frame 25, and a mounting net 31 is provided inside the mounting groove. By providing the mounting net 31, the hair dryer 3 can be protected and the iron slag debris can be blocked. The mounting net 31 is provided on one side of the hair dryer 3.

[0029] Among them, hair dryer 3 is the Porter BT-DG10 iron alloy hair dryer: this is a high-pressure resistant hair dryer made of iron alloy. It is suitable for scenes that require high pressure resistance and long-term use, and can blow iron slag debris.

[0030] Specifically, the working process or working principle of the clamping and positioning device for cutting rail vehicle profiles is as follows: in the specific cutting, clamping and positioning of rail vehicle profiles, the usual device uses a clamp to limit the profile during processing, and after the limiting is completed, the profile is cut using a cutting machine, etc. Although this method can cut the profile, the limiting effect is not comprehensive enough, which will affect the subsequent processing of the profile, and when the profile is cut, iron slag and debris may be generated, which is inconvenient for the operator to clean up. Therefore, the present technical solution can solve the above problems. When the operator needs to cut the profile, the operator can first place the profile on the top of the processing table 29, and then the operator can start the hydraulic cylinder 12 to drive the fixed plate 14 and the mounting frame 2 to move synchronously. When moving, since the height of the limit bar 18 is lower than the height of the cutting blade 22, the limit bar 18 can position the top of the two sides of the profile through the action of the spring 16. Through the continuous movement of the hydraulic cylinder 12, when the cutting blade 22 When it moves to contact the profile, the operator can first start the two groups of hydraulic cylinders 12 to move toward each other, clamp the two sides of the profile, start the motor 21 to drive the cutting blade 22 to rotate, so that the profile can be cut. Then, when the operator is cutting the profile, the profile can be fully clamped and positioned, which will not affect the subsequent processing of the profile and improve the processing efficiency of the profile. When the operator needs to clean the iron slag and debris generated by the profile, the operator can first use the cutting blade 22 to cut the profile. When cutting, the operator can start the hair dryer 3 to blow the iron slag and debris generated by the profile on the top of the processing table 29. At this time, since one side of the processing table 29 is inclined, the iron slag and debris can be blown into the inside of the drawer 27. When the profile processing is completed, the operator processes the iron slag and debris in the drawer 27, so that the iron slag and debris generated by the iron slag and debris can be centrally processed for easy use by the operator. At this point, all processes are completed.

[0031] It should be noted that the hydraulic cylinder 12, hydraulic rod 17, motor 21 and hair dryer 3 are all electrically connected to an external power supply and are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
