Description

TECHNICAL FIELD

[0001] The utility model relates to the detection technical field of axle sleeve, especially to a kind of equipment of the pressure of detection pressure. BACKGROUND

[0002] Axle sleeve plays an important role in the installation and uninstallation of shaft, and the outer diameter size of axle sleeve must have strict requirements to avoid over-loose or over-tight state during installation, so as to affect the working effect of axle sleeve. Therefore, the detection of the outer diameter of axle sleeve is particularly important. For example, Chinese patent CN201620130651.7 discloses an axle sleeve outer diameter detector, which includes a detector body, a sliding groove is provided on the detector body for sliding of the axle sleeve, and a drop channel is provided on the bottom surface of the sliding groove. The width of the drop channel gradually increases along the movement direction of the axle sleeve, so that the axle sleeve can drop from the drop channel during sliding. The detection method of the detector is as follows: the width of the drop channel is the detection scale of the outer diameter of the axle sleeve. That is, when the outer diameter of the axle sleeve is greater than the width of a certain position of the drop channel, the axle sleeve is supported by the sliding groove and does not fall off. When the outer diameter of the axle sleeve is smaller than the width of a certain position of the drop channel, the axle sleeve is separated from the sliding groove and falls off from the drop channel. However, when the axle sleeve falls at the critical point of the qualified range, it is difficult to determine whether the axle sleeve is compliant. That is, the position line of the axle sleeve drop coincides with or slightly deviates from the range line, and the position line of the axle sleeve drop at the moment is difficult to distinguish by naked eye. Therefore, the detection still has the risk of error, and the detection result is not clear. SUMMARY

[0017] The specific embodiments of the utility model are further explained below. It should be understood that the explanation of the utility model embodiments here is not used to limit the protection scope of the utility model.

[0018] As Figure 1 The utility model provides a detection pressure of pressure equipment's structural schematic drawing. The detection pressure of pressure equipment includes a rack 10, a lifting assembly 20 that is arranged in one side of rack 10, a pressure head assembly 30 that is arranged in the output end of lifting assembly 20, a through plate seat 40 that is arranged in one side of pressure head assembly 30 and a receiving box 50 that is arranged in one side of through plate seat 40. It is conceivable that the detection pressure of pressure equipment also includes some other functional modules, such as power module, screw module, data line module and the like, which are the technology that the person skilled in the art is familiar with, and will not be repeated here.

[0019] Please see Figures 2 to 5 The rack 10 includes a fuselage 11, a support 12 that is arranged in one side of fuselage 11, a base 13 that is arranged in one end of fuselage 11 close to support 12 and a top seat 14 that is arranged in one end of fuselage 11 away from base 13.

[0020] The bracket 12 is used to support the receiving box 50 to receive the shaft sleeve after the pressure detection. The base 13 is used to support the penetrating seat 40. It is conceived that a plurality of through holes are formed in the base 13 to facilitate the falling of the shaft sleeve. The through holes have a diameter larger than the outer diameter of the shaft sleeve and the axes of the through holes are on the same vertical line. The top seat 14 is used to support the lifting assembly 20. The top seat 14 corresponds to the base 13, so that the pressure head assembly 30 at the output end of the lifting assembly 20 can be aligned with the penetrating seat 40 to perform the pressure detection of the shaft sleeve.

[0021] The lifting assembly 20 comprises a servo motor 21, a driving wheel 22 arranged at the output end of the servo motor 21, a synchronous belt 23 sleeved on the driving wheel 22, a driven wheel 24 arranged at one end of the synchronous belt 23 away from the driving wheel 22, a lead screw 25 fixedly penetrating through the driven wheel 24, a ball screw nut 26 screwed on the lead screw 25, and a pressure cylinder 27 fixedly arranged on the ball screw nut 26.

[0022] The servo motor 21 can drive the driving wheel 22 to rotate, thereby driving the driven wheel 24 to rotate through the synchronous belt 23. The length direction of the lead screw 25 is parallel to the arrangement direction of the base 13 and the top seat 14. The driven wheel 24 drives the lead screw 25 to rotate. The ball screw nut 26 realizes linear motion under the support of the lead screw 26 through the thread cooperation and the rolling of the ball, thereby enabling the ball screw nut 26 to drive the pressure cylinder 27 to reciprocate along the length direction of the lead screw 25.

[0023] The pressure cylinder 27 is movably arranged at one end away from the driven wheel 24 on a mounting plate 28 fixedly arranged on the top seat 14. The mounting plate 28 is fixedly arranged with a housing 29 for supporting the lifting assembly 20. The mounting plate 28 is movably arranged with two guide columns 201. The end of the pressure cylinder 27 away from the driven wheel 24 is fixedly arranged with a pressure plate 202 for mounting the pressure head assembly 30. The pressure plate 202 is fixedly arranged with the ends of the two guide columns 201, so as to provide a certain guiding effect when the pressure cylinder 27 drives the pressure plate 202 to reciprocate.

[0024] The pressure head assembly 30 comprises a connecting block 31 fixedly arranged on one side of the pressure plate 202, an installation block 32 arranged on one side of the connecting block 31, a pressure sensor 33 arranged in the installation block 32, a pressure block 34 arranged on one side of the installation block 32, and at least four guide screws 35 screwed on the installation block 32.

[0025] The mounting block 32 is fixedly installed on the connecting block 31 away from the pressing plate 202 by screws, and a receiving cavity for accommodating the pressure sensor 33 is formed between the mounting block 32 and the connecting block 31. A through guide hole 36 is formed in the middle of the end of the mounting block 32 away from the connecting block 31, and part of the pressing block 34 is arranged to pass through the guide hole 36 to transmit the pressure on the pressing block 34 to the pressure sensor 33. A through hole is formed in one side of the mounting block 32 for passing a data line for connecting the pressure sensor 33 and an external display module.

[0026] The pressure sensor 33 can convert the pressure signal into an electrical signal, and the data can be presented on the screen after computer processing. The pressure sensor 33 itself is a prior art, and its acquisition of the pressure signal and the processing process will not be described here.

[0027] The pressing block 34 is movably arranged on the guide screw 35, and the head of the guide screw 35 is located on the side of the pressing block 34 away from the mounting block 32, so that the pressing block 34 can be hung on the guide screw 35 to avoid falling off the pressing head assembly 30.

[0028] The pressing block 34 is in the shape of a cylinder, and the cross-sectional diameter is greater than the inner diameter of the shaft sleeve and less than the outer diameter of the shaft sleeve, so that the pressing block 34 can press the end face of the shaft sleeve to avoid passing through the inner hole of the shaft sleeve. The pressing block 34 is provided with a pressing column 37 corresponding to the position of the guide hole 36, the pressing column 37 movably passes through the guide hole 36, and the end thereof faces the input end of the pressure sensor 33. Thus, when the pressing block 34 presses the shaft sleeve, the end of the pressing column 37 passes through the guide hole 36 and abuts against the input end of the pressure sensor 33, so as to transmit the pressure signal to the pressure sensor 33, and the pressure signal is converted by the pressure sensor 33 to obtain the pressure data, so as to judge the shaft sleeve by combining the data to detect whether it is qualified.

[0029] The through plate seat 40 is provided with a through hole 41 corresponding to the position of the pressing block 34, and the inner diameter of the through hole 41 is less than the standard data of the outer diameter of the qualified shaft sleeve, i.e. the inner diameter of the through hole 41 is the minimum value in the standard data range of the qualified shaft sleeve, so that the shaft sleeve to be detected can be placed on the through hole 41 without falling directly from the through hole 41.

[0030] The inner diameter of the perforation 41 is greater than the outer diameter of the pressing block 34, so that after the pressing block 34 presses the bushing into the perforation 41, it can continue to be pressed, so that the bushing is threaded through the perforation 41 and falls into the receiving box 50 through the through hole on the base 13 to complete the discharging operation.

[0031] In different embodiments, by replacing different perforated plate seats 40, the inner diameter of the perforation 41 is changed, so as to adapt to the detection of bushings of different specifications, thereby improving the adaptability of the equipment.

[0032] When the pressing block 34 presses the bushing into the perforation 41, if the pressure data measured by the pressure sensor 33 is greater than the standard range, it indicates that the outer diameter of the bushing is too large, and the bushing is determined to be an out-of-specification product. If the pressure data measured by the pressure sensor 33 is less than the standard range, it indicates that the outer diameter of the bushing is too small, and the bushing is determined to be an out-of-specification product. If the pressure data measured by the pressure sensor 33 is within the standard range, it indicates that the outer diameter of the bushing is qualified, and the bushing is determined to be a specification-compliant product. Thus, the detection process is convenient and fast, and the detection result is clear and unambiguous.

[0033] Compared with the prior art, the equipment for detecting the pressure of pressing provided by the utility model drives the pressing block 34 to press the bushing downward by the lifting assembly 20, presses the bushing into the perforation 41 on the perforated plate seat 40, and detects the pressure when the pressing block 34 is pressed by the pressure sensor 33, thereby obtaining pressure data. When the pressure data measured by the pressure sensor 33 is greater than the standard range, it indicates that the outer diameter of the bushing is too large, and the bushing is determined to be an out-of-specification product. When the pressure data measured by the pressure sensor 33 is less than the standard range, it indicates that the outer diameter of the bushing is too small, and the bushing is determined to be an out-of-specification product. Thus, through digital comparison, the detection result is clear and unambiguous, even if the bushing is at the critical point of the qualified range, it can also be determined whether it is compliant by comparing the size of the pressure data. The equipment can replace different perforated plate seats 40 to change the inner diameter of the perforation 41, so as to adapt to the detection of bushings of different specifications. The detection process of the equipment for detecting the pressure of pressing is convenient and fast, and the detection result obtained is clear and unambiguous, and the adaptability is efficient.

[0034] The above is only a preferred embodiment of the utility model, and is not used to limit the protection scope of the utility model, any modification, equivalent replacement or improvement within the spirit of the utility model is covered within the claim scope of the utility model.
