Description

Technical Field

[0001] This application relates to a break-in device, and more particularly to an isobaric break-in device capable of simultaneously performing pressure calibration for multiple force sensors. Background Technology

[0002] Currently, the break-in and calibration of force sensors mostly involves calibrating a single force sensor using a break-in machine. Therefore, increasing the number of force sensors to be calibrated significantly increases the process time. Furthermore, because different force sensors have different machining tolerances, directly using a rigid fixture to run-in and calibrate multiple force sensors with a press will cause deviations in the pressure applied to each sensor due to these tolerances, resulting in a failure to achieve isobaric pressure and causing problems with the break-in and calibration process. In addition, using excessive pressure on the press can easily cause problems or damage to some force sensors.

[0003] In view of this, the applicant has devoted himself to researching and applying theoretical principles to address the shortcomings of the prior art, and has made every effort to solve the aforementioned problems, which has become the target of the applicant's improvement. Utility Model Content

[0004] The main purpose of this application is to eliminate the machining tolerances of each force sensor by finely adjusting the angle and position of each adjusting rod through hydraulic oil, thereby achieving isobaric pressure and simultaneously running-in and calibrating multiple force sensors.

[0005] To achieve the above objectives, this application provides an isobaric running-in device for simultaneously performing press-fit calibration on multiple force sensors. The isobaric running-in device includes: a frame; a pressure plate disposed on the frame; an isobaric mechanism disposed on the frame and including a base, multiple adjusting rods, and hydraulic oil, wherein each adjusting rod is movably connected to the base and respectively carries each force sensor, and the hydraulic oil is filled in the base; and a driver disposed on the frame and corresponding to one of the pressure plate and the isobaric mechanism, wherein the driver can drive the corresponding pressure plate or the isobaric mechanism to move closer to or away from the other of the pressure plate and the isobaric mechanism; wherein when the pressure plate presses against each force sensor carried by each adjusting rod, each adjusting rod is finely adjusted relative to the base by the hydraulic oil so that each force sensor can press against the pressure plate with equal pressure.

[0006] In one embodiment of this application, the base includes a body and a cover plate. The body has a receiving groove and a plurality of through grooves. The cover plate is on the body and closes the receiving groove. Each through groove is connected to the receiving groove and is located on the side of the body away from the cover plate. Each adjusting rod passes through each through groove. Hydraulic oil is filled in the receiving groove.

[0007] In one embodiment of this application, the equal pressure mechanism further includes a plurality of positioning rings, each positioning ring being disposed in a slot and sleeved with a corresponding adjusting rod.

[0008] In one embodiment of this application, each adjusting rod includes a support base and a movable rod body. The movable rod body is movably connected to a corresponding through slot. The support base is disposed at one end of the movable rod body and protrudes outside the support body to support the corresponding force sensor.

[0009] In one embodiment of this application, in each adjusting rod, the movable rod body has a flange, and the corresponding positioning ring can stop the flange to prevent the adjusting rod from disengaging from the corresponding slot.

[0010] In one embodiment of this application, each adjusting rod further includes an oil-blocking seat and a rubber ring. The oil-blocking seat is connected to the end of the movable rod away from the bearing seat, and the rubber ring elastically abuts against the movable rod and the oil-blocking seat.

[0011] In one embodiment of this application, the seat body further has a plurality of limiting protrusions, each limiting protrusion being located in a through groove, and a positioning ring in each through groove abutting against one side of the corresponding limiting protrusion.

[0012] In one embodiment of this application, a plurality of positioning rings are provided in each through groove, and each positioning ring in each through groove is respectively arranged on the opposite sides of the corresponding limiting protrusion.

[0013] In one embodiment of this application, the base further includes a sealing gasket, and the base body also has an annular groove. The annular groove is located on the side of the base facing the cover plate and surrounds the receiving groove. The sealing gasket is received in the annular groove and elastically abuts against the base and the cover plate.

[0014] In one embodiment of this application, the adjusting rods are symmetrically arranged on the base.

[0015] The isobaric running-in equipment of this application uses adjustable rods that can be movably connected to the base and respectively carry each force sensor. Hydraulic oil is filled into the base, so that when the pressure plate presses against each force sensor carried by each adjustable rod, each adjustable rod can be finely adjusted in angle and position by hydraulic oil. This eliminates the tolerances generated during the processing of each force sensor, thereby achieving the effect of isobaric running-in and calibration of multiple force sensors at the same time, and thus greatly reducing the process time.

[0047] The detailed description and technical content of this application will be explained below with reference to the accompanying drawings. However, the drawings are for illustrative purposes only and are not intended to limit the scope of this application.

[0048] This application provides an isobaric running-in device for simultaneously performing pressure calibration on multiple force sensors A. Please refer to [the relevant documentation / reference]. Figures 1 to 4 As shown, the isobaric break-in equipment of this application includes a frame 10, a pressure plate 20, an isobaric mechanism 30, and a driver 40.

[0049] The frame 10 mainly includes a top plate 11 and a bottom plate 12. The top plate 11 is arranged parallel above the bottom plate 12. The frame 10 may also include a plurality of support columns (not shown) connected between the top plate 11 and the bottom plate 12 to form a stable frame structure, but this application does not impose any restrictions on the specific form or structure of the frame 10.

[0050] The pressure plate 20 is disposed on the frame 10. Specifically, the pressure plate 20 is disposed on the side of the top plate 11 facing the bottom plate 12, that is, the pressure plate 20 is located between the top plate 11 and the bottom plate 12. The side of the pressure plate 20 facing the bottom plate 12 is a flat surface that has been precision machined and ground. More specifically, in this embodiment, the flatness of the flatness of the plane of the pressure plate 20 facing the bottom plate 12 is no greater than 0.3 mm, but this application does not impose any further limitations on this.

[0051] An isobaric mechanism 30 is mounted on the base of the frame 10 and includes a base 31, multiple adjusting rods 32, and a hydraulic oil 33. Each adjusting rod 32 is movably connected to the base 31 and carries a force sensor A. Specifically, the base 31 includes a body 311 and a cover plate 312. The body 311 has a receiving groove 3111 and multiple through grooves 3112. The receiving groove 3111 is recessed upward from the bottom of the body 311. Each through groove 3112 communicates with the receiving groove 3111 and is located on the side of the body 311 away from the cover plate 312. The cover plate 312 bases the body 311 and closes the receiving groove 3111. Specifically, in this embodiment, the cover plate 312 is secured to the bottom of the base 311 by multiple bolts. However, this application is not limited to this; for example, the cover plate 312 can also be fixed to the bottom of the base 311 by means of snap-fit, buckle, welding, or fusion. Each adjusting rod 32 passes through each through slot 3112. The hydraulic oil 33 is filled into the receiving groove 3111 of the base 31, and the hydraulic oil 33 is confined within the receiving groove 3111 by the cover plate 312 and each adjusting rod 32, preventing it from overflowing.

[0052] The driver 40 is disposed on the frame 10 and corresponds to one of the pressure plate 20 and the equalization mechanism 30. The driver 40 can drive the corresponding pressure plate 20 or equalization mechanism 30 to move closer to or away from the other. In this embodiment, the driver 40 is a servo motor and is disposed on the frame 10 corresponding to the equalization mechanism 30, so the driver 40 can drive the equalization mechanism 30 to move closer to or away from the pressure plate 20. However, this application is not limited thereto. For example, the driver 40 can also be a cylinder, an electric actuator, or other forms of linear actuator, and the driver 40 can also be disposed on the frame 10 corresponding to the pressure plate 20 and be able to drive the pressure plate 20 to move closer to or away from the equalization mechanism 30, as in another embodiment of this application. Figure 5 As shown.

[0053] Therefore, refer to Figure 4 As shown, when the driver 40 drives the equal pressure mechanism 30 to move closer to the pressure plate 20, causing the pressure plate 20 to press against each force sensor A carried on each adjusting rod 32, each adjusting rod 32 can be finely adjusted relative to each through groove 3112 by the hydraulic oil 33 inside the receiving groove 3111 of the base 31, so that each force sensor A can be pressed against the pressure plate 20 with equal pressure. More specifically, each adjusting rod 32 can be finely adjusted in angle and position within each through groove 3112 by the hydraulic oil 33, thereby eliminating the tolerances generated during the processing of each force sensor A, so that the pressure plate 20 achieves an equal pressure effect on each force sensor A. Therefore, the equal pressure running-in equipment of this application can simultaneously run-in and correct multiple force sensors A, thereby significantly reducing the process time.

[0054] Further explanation: the equal pressure mechanism 30 also includes multiple positioning rings 34. Each positioning ring 34 is respectively disposed in each slot 3112 of the base 31, and each positioning ring 34 is respectively sleeved on the corresponding adjusting rod 32. Thus, by having each positioning ring 34 sleeve on the corresponding adjusting rod 32, the stability of each adjusting rod 32 when sliding relative to the base 31 can be improved, thereby reducing the angle and position that each adjusting rod 32 needs to be fine-tuned using hydraulic oil 33. It is worth mentioning that, due to the high machining precision of the positioning rings 34, the range of motion of the adjusting rod 32 can be effectively limited, thereby effectively reducing the angle and position that each adjusting rod 32 needs to be fine-tuned. In this embodiment, two positioning rings 34 are provided in each slot 3112, thereby further improving the stability of each adjusting rod 32 when sliding and further effectively reducing the angle and position that each adjusting rod 32 needs to be fine-tuned. However, this application is not limited to this; for example, the number of positioning rings 34 provided in each slot 3112 may be only one or more.

[0055] In addition, in this embodiment, each adjusting rod 32 includes a support 321, a movable rod 322, an oil-blocking seat 323, and a rubber ring 324. The movable rod 322 is movably connected to the corresponding through slot 3112. The support 321 is located at the top of the movable rod 322 and protrudes outside the seat 311 to support the corresponding force sensor A. The oil-blocking seat 323 is connected to the bottom end of the movable rod 322 away from the support 321 to confine the hydraulic oil 33 within the groove 3111, that is, the support 321 and the oil-blocking seat 323 are respectively connected to the opposite ends of the movable rod 322. The rubber ring 324 elastically abuts against the movable rod 322 and the oil-blocking seat 323, thereby effectively preventing the hydraulic oil 33 from seeping between the oil-blocking seat 323 and the movable rod 322.

[0056] In each adjusting rod 32, the movable rod body 322 has a flange 3221. The positioning ring 34 corresponding to each adjusting rod 32 can stop the flange 3221, thereby effectively preventing the adjusting rod 32 from disengaging from the corresponding through groove 3112. In other words, before the cover plate 312 is fixed to the base 31, each adjusting rod 32 is inserted into the receiving groove 3111 from the bottom of the base 31 until each adjusting rod 32 passes through the corresponding through groove 3112 and abuts against the corresponding positioning ring 34 through its flange 3221 to confirm that it is installed in the correct position. In addition, in order to effectively position the installation depth of each positioning ring 34, the base body 311 also has a plurality of limiting protrusions 3113. Each limiting protrusion 3113 is located in each through groove 3112, and each positioning ring 34 in each through groove 3112 abuts against one side of the corresponding limiting protrusion 3113. In this embodiment, each positioning ring 34 in each through groove 3112 is respectively disposed and abuts against the opposite sides of the corresponding limiting protrusion 3113. Thus, each positioning ring 34 in each through groove 3112 can be placed in the through groove 3112 from the top of the base 31, and can be placed in the through groove 3112 from the bottom of the base 31 via the receiving groove 3111, so that each positioning ring 34 abuts against the opposite sides of the limiting protrusion 3113 to form a positioning.

[0057] Further, the base 31 also includes a sealing gasket 313. The seat 311 of the base 31 also has an annular groove 3114. Specifically, the annular groove 3114 is located on the side of the base 31 facing the cover plate 312 and surrounds the periphery of the receiving groove 3111. The sealing gasket 313 is accommodated in the annular groove 3114, and the sealing gasket 313 elastically abuts against the base 31 and the cover plate 312, thereby effectively preventing hydraulic oil 33 from leaking out between the seat 311 and the cover plate 312. In addition, each adjusting rod 32 is symmetrically arranged on the base 31, so that when the pressure plate 20 presses against each force sensor A on each adjusting rod 32, the force can be evenly distributed without skewing. In this embodiment, the number of adjusting rods 32 is four, but this application is not limited to this. For example, there can be two, three, or more adjusting rods 32, as long as the adjusting rods 32 are symmetrically arranged.

[0058] The isobaric running-in equipment of this application uses adjusting rods 32 that can be movably connected to the base 31 and respectively carry each force sensor A. Hydraulic oil 33 is filled into the base 31, so that when the pressure plate 20 presses against each force sensor A carried by each adjusting rod 32, each adjusting rod 32 can be finely adjusted in angle and position by hydraulic oil 33. This eliminates the tolerances generated during the processing of each force sensor A, thereby achieving the effect of isobaric running-in and calibration of multiple force sensors A at the same time, and thus greatly reducing the process time.

[0059] In summary, the foregoing description in this application is intended to enable those skilled in the art to clearly understand the technical content of this application and implement it accordingly, and is not intended to limit the scope of patent protection of this application. In addition, this application may of course have other embodiments not listed. Without departing from the spirit and essence of this application, those skilled in the art should be able to devise various corresponding changes and modifications based on this application, but all such corresponding changes and modifications should fall within the scope of protection of the patent claimed in this application.
