Description

Technical Field

[0001] The invention relates to the technical field of metal parts detection, and in particular to an automatic metal parts detection device. Background Art

[0002] Metal shaft parts are a very common basic part in hardware accessories. Their main function is to support the components of various transmission devices, realize the transmission of torque and withstand various working loads. According to the different structural forms of shaft parts, they can generally be divided into three categories: smooth shafts, stepped shafts and special-shaped shafts; or into solid shafts, hollow shafts, etc.

[0003] Except for the linear optical axis (whose diameter is basically unchanged along the axial direction and has no external protrusions), most of the other shaft parts, such as stepped shafts or other asymmetric shaft parts, have multiple cylindrical sections with different diameters in the axial direction. As a result, when these shaft parts are tested for coaxiality or end face runout, if the two ends of the shaft are directly placed on the support blocks on both sides, the contact points with the support blocks at different diameters will be at different heights, causing the shaft to be placed in an inclined state as a whole, and the axis of the shaft will not be parallel to the reference plane of the testing instrument, or the end face of the shaft will not be able to completely contact the detection needle of the testing instrument, thus affecting the accuracy of the test results.

[0004] In order to solve this problem, it is usually necessary to make matching V-shaped pads in advance according to the size of the shaft to be tested to ensure that both ends of the shaft can be fully supported, which is rather troublesome. In addition, such customized V-shaped pads can only be used for shafts of specific sizes and cannot be reused for shafts of other sizes, thus causing a certain amount of resource waste.

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] The present invention will be further described below in conjunction with the embodiments.

[0024] Example 1, reference Figure 1 - Figure 4 , which is the first embodiment of the present invention, provides an automated metal parts detection device, including a detection table 1, an electric rail installed on the table top of the detection table 1, and a three-coordinate detector 2 installed on the electric rail, a leveling component 3 for placing shaft parts is installed on the detection table 1, and the leveling component 3 is located on the front of the three-coordinate detector 2.

[0025] Specifically, the three-coordinate measuring machine 2 can be composed of a three-axis robotic arm and an automatic detection component, which includes but is not limited to a probe, a detection needle and a sensor. The detection needle touches the cylindrical surface or end face of the axis to be detected to complete the coaxiality or end face runout detection of the metal parts. This is a prior art and will not be elaborated here.

[0026] Specifically, before detecting the end face runout of shaft parts, it is necessary to first detect their coaxiality, which is the basic accuracy requirement for shaft parts. If there is a large error in coaxiality, the actual axis of the shaft deviates from the reference axis. In this case, when detecting the end face runout, due to the inaccurate axis position of the shaft itself, the measurement result of the end face runout will include additional deviations caused by the coaxiality error.

[0027] Specifically, a control host is provided on the detection table 1. The control host adopts a computer in the prior art. The specific structural composition and working principle are not particularly limited here as long as it can complete basic detection operations such as program control, signal reception, data processing and analysis. The control host includes but is not limited to a controller, a receiving module and a processing module. The control host is connected to the three-coordinate measuring instrument 2 for wired or wireless control.

[0028] Reference Figure 1 and Figure 2 The leveling assembly 3 includes an integrally formed mounting base 31 connected to the surface of the detection table 1, an adjusting block 32 and a positioning block 33 are installed on the mounting base 31, and the positioning block 33 is located on one side of the adjusting block 32, a first cushion block 34 is provided on the top of the adjusting block 32, a second cushion block 35 is fixedly installed on the top of the positioning block 33, a threaded rod 36 and a limit rod 37 are rotatably installed on the top of the adjusting block 32, and the threaded rod 36 is threadedly connected to the adjusting block 32, the limit rod 37 is located on one side of the threaded rod 36, and the limit rod 37 is movably passed through the wall of the adjusting block 32; a "V"-shaped groove is opened on the first cushion block 34, and the second cushion block 35 has the same structure as the first cushion block 34.

[0029] Specifically, a slide bar (shown in the figure but not numbered) is fixedly mounted on the mounting seat 31, the axis of the slide bar is parallel to the reference plane of the three-dimensional coordinate measuring instrument 2, the positioning block 33 is fixedly mounted on the slide bar, and the adjustment block 32 is slidably mounted on the slide bar, so that the adjustment block 32 can be slidably adjusted left and right along the axis of the slide bar; since there are many types of sizes of shaft parts to be inspected, it can quickly adapt to shafts of different lengths and diameters, and the inspector can intuitively observe the size of the shaft, and then immediately make corresponding sliding adjustments to the position of the adjustment block 32.

[0030] The mounting seat 31 can also be mounted by rotating the lead screw, and the adjusting block 32 is fixedly mounted on the top of the mounting seat 31. The adjusting block 32 is threadedly mounted on the lead screw, and a driving motor is installed at the end of the lead screw to electrically adjust the horizontal position of the adjusting block 32.

[0031] Specifically, a knob is fixedly mounted on the top of the threaded rod 36 to facilitate adjusting the height of the first cushion block 34 .

[0032] Specifically, the distance between the adjusting block 32 and the positioning block 33 is adjusted according to the length of the axis to be detected, the cylindrical segment with a small diameter is placed on the adjusting block 32, and the cylindrical segment with a large diameter is placed on the positioning block 33, and then the threaded rod 36 is rotated to move the adjusting block 32 upward, so that the inclined axis gradually becomes horizontally placed until the axis of the entire axis to be detected is parallel to the horizontal reference plane of the three-coordinate measuring instrument 2, which is convenient for subsequent detection of coaxiality or end face runout. There is no need to customize various V-shaped pads in advance, which can ensure that axes of different sizes to be detected are in a horizontal state when supported, thereby improving the size adaptability of different axes to be detected.

[0033] Reference Figure 2 - Figure 4 The side of the positioning block 33 away from the adjusting block 32 is connected to a fixed block 38, a wedge-shaped groove is opened in the fixed block 38, a rectangular long block 39 is inserted on one side of the vertical surface of the wedge-shaped groove, and a horizontal frame 310 is rotatably installed on the top of the rectangular long block 39 through a connecting rod; a counterweight column 311 is provided on one side of the inclined surface in the wedge-shaped groove, and an anti-slip pad is bonded to the outer surface of the counterweight column 311, and an extrusion rod 312 is slidably connected to the wall of the fixed block 38, the rod body of the extrusion rod 312 is located at the bottom of the counterweight column 311, and an inclined push surface is provided on the extrusion rod 312.

[0034] Specifically, the extrusion rod 312 is pushed obliquely toward the counterweight column 311, so that the counterweight column 311 moves upward in the wedge-shaped groove. At this time, the counterweight column 311 can move to both sides in the wedge-shaped groove, and the height of the rectangular long block 39 is adjusted according to the size of the axis to be detected. After the height adjustment is completed, the extrusion rod 312 is pushed obliquely away from the counterweight column 311. The counterweight column 311 moves downward under the action of gravity, so that the outer surface of the counterweight column 311 (with an anti-slip pad bonded to it) is in close contact with the outer wall of the rectangular long block 39, ensuring that the rectangular long block 39 will not move due to gravity or other external forces, thereby completing stepless adjustment according to the size of different axes to be detected, and achieving more accurate height positioning and a wider adjustment range.

[0035] Reference Figure 4 Both ends of the extrusion rod 312 are movable through the outer wall of the fixed block 38, one end of the extrusion rod 312 is fixedly installed with a pressing block, and a first elastic member is connected between the pressing block and the outer wall of the fixed block 38.

[0036] Specifically, by pressing the pressure block inward, the inclined push surface on the extrusion rod 312 is brought closer to the counterweight column 311; the first elastic member can be a compression spring or spring sheet commonly used in the prior art, and here it is preferably a compression spring that can withstand axial tension, so that after the pressure on the pressure block is released, the extrusion rod 312 automatically resets, and the inclined push surface on the extrusion rod 312 moves away from the counterweight column 311, and the counterweight column 311 moves downward again, and the anti-slip pad is against the outer wall of the rectangular long block 39, thereby completing the fixation of the height position of the rectangular long block 39 by increasing the friction force.

[0037] Reference Figure 4 , horizontal frame 310 is symmetrically provided with horizontal grooves 313 , a moving block 314 is slidably connected between the two horizontal grooves 313 , a micrometer is fixedly installed at the center of the moving block 314 , and a push rod is fixedly installed on the outer wall of the moving block 314 .

[0038] Specifically, a mounting rod ( Figure 5 310, and the position of the moving block 314 and the micrometer can be fixed by tightening the nut after the detection is completed.

[0039] Specifically, after manually moving the rectangular long block 39 up and down to adjust the height of the horizontal frame 310, the contact end of the bottom of the micrometer is made to contact the outer surface of the cylindrical segment closest to it, and the push rod is pulled to move the moving block 314 in the horizontal groove 313 (when pushing the moving block 314, the height of the adjustment block 32 is fine-tuned to ensure that the contact end of the micrometer is always in contact with the outer surface of the shaft to be tested), and the reading on the micrometer is used to determine whether the axis of the shaft to be tested is completely parallel to the horizontal reference plane of the three-dimensional coordinate measuring instrument 2.

[0040] Example 2, reference Figure 1 - Fig. 9 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: an auxiliary component 4 is installed on the horizontal frame 310, and the auxiliary component 4 includes a prompt block 41 fixedly installed between two horizontal grooves 313, a trigger block 42 is arranged in the prompt block 41, and a groove adapted to the trigger block 42 is opened in the prompt block 41, and a flip plate 43 is rotatably installed on the outer wall of the prompt block 41 through a torsion spring; the inner side surface of the flip plate 43 close to the trigger block 42 is red, and the outer side surface of the flip plate 43 away from the trigger block 42 is green.

[0041] Specifically, as the moving block 314 moves completely from one side to the other side in the horizontal groove 313, the moving block 314 first contacts the trigger block 42, and then pushes the trigger block 42 to move toward the flip plate 43, so that the flip plate 43 rotates 90° about the axis of the shaft, completing the outward expansion of the red inner side of the flip plate 43 (at this time, the red inner side of the flip plate 43 is opposite to the inspector), and the green outer side of the flip plate 43 rotates to the back, so that the inspector can clearly see that the axis of the axis to be inspected has been completed and is parallel to the horizontal reference plane of the three-coordinate measuring instrument 2.

[0042] Reference Figure 6 - Fig. 9, a movable cavity 44 is provided in the prompt block 41, and the movable cavity 44 is located on both sides of the groove, a sleeve 46 is rotatably installed on the inner wall of the movable cavity 44 through a shaft 45, and a telescopic rod 47 is slidably connected in the sleeve 46, and one end of the telescopic rod 47 away from the sleeve 46 is fixedly connected to a rotating plate 48, and connecting ears are connected to both sides of the trigger block 42, and the rotating plate 48 is rotatably connected to the outer wall of the trigger block 42 through the connecting ears and the rotating shaft; a second elastic member is connected between the sleeve 46 and the outer wall of the rotating plate 48, a connecting block 49 is fixedly installed on the inner wall of the movable cavity 44, a rubber plug 410 is connected to the outer wall of the connecting block 49, and a locking groove adapted to the shape of the rubber plug 410 is provided on the outer wall of the rotating plate 48; when the moving block 314 is not in contact with the trigger block 42, the telescopic rod 47 is retracted into the sleeve 46, and the second elastic member is in a compressed state.

[0043] Specifically, the second elastic member is preferably a compression spring that can withstand axial pressure and has the ability to store elastic energy.

[0044] Specifically, when the trigger block 42 moves toward the side close to the flip plate 43, the rotating plate 48 rotates. At this time, the telescopic rod 47 and the sleeve 46 no longer maintain a horizontal state. Under the elastic action of the second elastic member, the telescopic rod 47 is pushed diagonally upward and pops out quickly. The telescopic rods 47 on both sides push the trigger block 42 to pop out quickly as a whole, thereby causing the trigger block 42 to lift and unfold the flip plate 43, indicating to the inspector that the leveling operation has been completed.

[0045] Specifically, the rubber plug 410 can be in the shape of a right-angled trapezoid. The rubber plug 410 has moderate hardness and elasticity. When compressed, it can produce reversible deformation without causing permanent impact on its restoration to its original state. When the rotating plate 48 is driven to move upward, the card lock of the rotating plate 48 can be released. At the same time, when the rotating plate 48 is pressed downward, the locking function is realized. The design of the rubber plug 410 allows it to flexibly perform locking and unlocking operations during the movement of the rotating plate 48.

[0046] Reference Figure 4 and Figure 5 Both ends of the moving block 314 are made of magnetic material, and a magnetic attraction plate 411 is installed between the prompt block 41 and the horizontal groove 313, and the magnetic attraction plate 411 and the moving block 314 are magnetically attracted.

[0047] Specifically, when the moving block 314 moves in the horizontal groove 313 and gradually approaches the magnetic plate 411, the magnetic attraction of the magnetic plate 411 can accurately fit the moving block 314 thereto, and the magnetic plate 411 provides an acceleration to the moving block 314 during the process of absorbing the moving block 314 (the specific magnitude of this acceleration depends on the actual mass of the moving block 314 and the magnitude of the magnetic attraction), so that the moving block 314 can move quickly, the auxiliary rubber plug 410 can smoothly escape from the lock groove, and the flip plate 43 is quickly lifted up and unfolded. The rest of the structure is the same as that of Example 1.

[0048] Example 3, reference Figure 1 - Fig.11 , which is the third embodiment of the present invention, is different from the second embodiment in that: during transportation, processing or storage, the end face of the shaft part may be worn due to collision, forming an inclined surface; or the end face may produce burrs or be contaminated with impurities such as oil, dust, etc., which will affect the measurement accuracy of the probe. Therefore, before detecting the end face runout of the shaft part, it is usually necessary to grind the end face appropriately to ensure the flatness of the end face, so as to perform accurate measurement.

[0049] Reference Figure 2 , Fig.10 and Fig.11 A grinding assembly 5 is installed between the leveling assembly 3 and the auxiliary assembly 4. The grinding assembly 5 includes a material receiving box 51 fixedly installed or welded on the side wall of the first cushion block 34. A grinding motor 52 is fixedly installed on the material receiving box 51, and a grinding disc is installed on the output shaft of the grinding motor 52. A telescopic air pipe 53 is detachably installed on the side wall of the material receiving box 51, and the telescopic air pipe 53 is connected to the inner cavity of the material receiving box 51; an air guide bin 54 is arranged on the top of the prompt block 41, and the air guide bin 54 is A piston rod 55 is slidably connected to the inner cavity, and one end of the piston rod 55 away from the air guide bin 54 is fixedly connected to the outer wall of the trigger block 42 through an extension plate, and the other end of the telescopic air pipe 53 is connected to the inner cavity of the air guide bin 54; a one-way valve 56 is installed on the wall of the air guide bin 54, and the flow direction of the one-way valve 56 is one-way from the inside of the air guide bin 54 to the outside of the air guide bin 54, so that when the piston rod 55 moves to the side of the flip plate 43 with the trigger block 42, the gas flows out from the one-way valve 56.

[0050] Specifically, a material receiving inclined surface is provided in the material receiving box 51 (refer to Fig.10 ), and fits with the side wall of the first cushion block 34 to receive the grinding chips generated during grinding and prevent the grinding chips from falling onto the mounting seat 31 and affecting the movement of the adjusting block 32.

[0051] Specifically, when the red inner side of the flip plate 43 is opposite to the inspector, the grinding motor 52 is turned on to rotate the grinding disc, and the end face of the shaft to be inspected is pushed toward the side of the grinding motor 52. In this way, the grinding disc properly grinds the end face of the shaft, thereby facilitating the subsequent accurate measurement of the three-coordinate detector 2; after the grinding is completed, the moving block 314 (micrometer) and the trigger block 42 are reset. During the resetting process of the trigger block 42, the piston rod 55 connected to it is evacuated. Under the connection of the telescopic air pipe 53, the grinding chips in the receiving box 51 are sucked into the telescopic air pipe 53. Subsequently, it is only necessary to remove the telescopic air pipe 53 for flushing inside the pipe.

[0052] Specifically, the telescopic air tube 53 is preferably a thin corrugated tube. When the adjustment block 32 is adjusted according to the different lengths of the shaft to be detected, the telescopic air tube 53 can freely expand and contract to adapt to itself.

[0053] Reference Fig.10 A mounting frame 57 is symmetrically connected to the material receiving box 51, and a clamping rod 58 is slidably connected to the side of the mounting frame 57 close to the grinding motor 52, and a third elastic member is connected between the outer wall of the clamping rod 58 and the inner wall of the mounting frame 57, and an arc-shaped electromagnet 59 is fixedly installed at one end of the clamping rod 58. The two opposing arc-shaped electromagnets 59 are magnetically attracted to each other when energized, and the arc-shaped electromagnet 59 is always opened and closed synchronously with the grinding motor 52.

[0054] Specifically, the third elastic member is preferably a compression spring that can withstand axial pressure and has the ability to store elastic energy, so that after the arc electromagnet 59 is powered off, the arc electromagnet 59 can automatically reset away from the axis to be detected.

[0055] Specifically, when the grinding motor 52 is turned on, the arc electromagnet 59 is energized, and the two arc electromagnets 59 approach the shaft to be tested to clamp the cylindrical surface of the shaft to be tested, thereby improving the stability of the grinding disc when grinding the end surface.

[0056] Based on Examples 1-3, the working principle of the present invention is as follows: Place the two ends of the axis to be detected on the adjustment block 32 and the positioning block 33 respectively, change the height of the adjustment block 32 by the threaded rod 36 (at this time, the axis to be detected is roughly in a parallel state), and one end of the axis to be detected located on the adjustment block 32 is located between the two arc-shaped electromagnets 59, push the extrusion rod 312 obliquely toward the counterweight column 311, and adjust the height of the horizontal frame 310 according to the diameter of any cylindrical segment on the axis to be detected, so that the contact end at the bottom of the micrometer contacts the outer surface of the cylindrical segment closest to it, and then pull the push rod to make the moving block 314 move in the horizontal groove 313, and fine-tune the height of the adjustment block 32 by the degree on the micrometer until the degree on the micrometer does not change, and the axis of the axis to be detected is completely parallel to the horizontal reference plane of the three-dimensional coordinate measuring instrument 2.

[0057] As the moving block 314 moves in the horizontal groove 313 and gradually approaches the magnetic plate 411, the magnetic attraction of the magnetic plate 411 accurately fits the moving block 314 therewith, and the moving block 314 pushes the trigger block 42 to move toward the flip plate 43, and the rotating plate 48 rotates. Under the elastic action of the second elastic member, the telescopic rod 47 is pushed obliquely upward and pops out quickly, and the telescopic rods 47 on both sides push the trigger block 42 to pop out quickly as a whole, thereby causing the trigger block 42 to lift and unfold the flip plate 43, and the axis of the axis to be detected is parallel to the horizontal reference plane of the three-dimensional coordinate measuring instrument 2.

[0058] When the red inner side of the flip plate 43 is opposite to the inspector, the grinding motor 52 is turned on to rotate the grinding disc, and the two arc-shaped electromagnets 59 clamp the cylindrical surface of the shaft to be inspected. The inspector pushes the end face of the shaft to be inspected toward the side of the grinding motor 52. In this way, the grinding disc properly grinds the end face of the shaft. After the grinding is completed, the grinding motor 52 and the arc-shaped electromagnet 59 are powered off and turned off, and the moving block 314 and the trigger block 42 are reset. During the resetting process of the trigger block 42, the piston rod 55 connected to it is evacuated, and under the connection of the telescopic air pipe 53, the grinding chips in the receiving box 51 are sucked into the telescopic air pipe 53, and then the shaft to be inspected is moved away from the grinding disc (until the subsequent detection needle of the three-dimensional coordinate measuring instrument 2 can contact the end face), and the automatic metal parts detection of the three-dimensional coordinate measuring instrument 2 is started.
