Description
Technical Field
[0001] The utility model belongs to the technical field of electric motorcycle manufacturing, in particular to a deformation inspection tool for electric motorcycle special-shaped parts with a column. Background Art
[0002] Some special-shaped parts of electric motorcycles mainly include a column part and a shell part, such as the single rocker arm of an electric motorcycle, which mainly includes a column for connecting to the shock absorbing mechanism and a single rocker arm shell connected to the column. The special-shaped parts of electric motorcycles need to go through the processes of casting and heat treatment. After the casting and heat treatment processes, the special-shaped parts may be deformed, especially at the column part of the special-shaped parts, resulting in poor verticality of the column; at the same time, the deformation of the special-shaped part shell will also cause the column of the special-shaped part to shift. If the deformed special-shaped parts are directly flowed into the machining workshop without being shaped, it is easy to cause the eccentricity of the machined special-shaped parts to be scrapped. At present, there is no detection device on the market for detecting the deformation of special-shaped parts of electric motorcycles. Utility Model Content
[0003] The utility model aims to provide an electric scooter special-shaped part deformation inspection tool with a column, which can detect the deformation of the electric scooter special-shaped part and judge whether the special-shaped part is deformed, thereby preventing the deformed special-shaped part from directly flowing into a machining workshop, causing the special-shaped part after machining to be eccentric and scrapped.
[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an electric motorcycle special-shaped part deformation inspection tool with a column, comprising a bottom plate, at least one opposing positioning block and a lateral positioning block are provided on the bottom plate, the opposing positioning block is provided with an opposing positioning surface with the same shape as the outer wall of the shell of the special-shaped part standard part, the lateral positioning block is provided with a lateral positioning surface with the same shape as the outer wall of the shell of the special-shaped part standard part, and the extension directions of the opposing positioning surface and the lateral positioning surface are arranged to intersect; a transverse pressing member is provided on the opposite side of the opposing positioning block, and the transverse pressing member is used to push the shell of the special-shaped part to be detected to the opposing positioning surface; a positioning seat extending upward is provided on the bottom plate, and a detection member is provided on the upper end of the positioning seat, and the detection member can move close to or away from the column to be detected, and the detection member is provided with a detection groove which passes through from top to bottom and opens laterally, the circumferential inner edge shape of the detection groove is the same as the circumferential outer edge shape of the column standard part, and the circumferential inner wall of the detection groove is used to contact the circumferential outer wall of the column to be detected.
[0005] During use, the operator places the special-shaped part to be detected on the bottom plate, and one side of the special-shaped part to be detected contacts the lateral positioning surface. Then the transverse pressing part pushes the shell of the special-shaped part to be detected, so that the shell of the special-shaped part to be detected contacts the opposite positioning surface; then the operator moves the detection part so that the detection groove is close to the column to be detected, and the operator observes whether the column to be detected can enter the detection groove. If the column to be detected can enter the detection groove, the operator observes whether the circumferential outer wall of the column to be detected contacts the circumferential inner wall of the detection groove. If so, it means that the verticality of the column meets the requirements; if the column cannot enter the detection groove, or after entering the detection groove, it is found that the circumferential outer wall of the column is in line contact with the circumferential inner wall of the detection groove, it means that the column has been deformed and the verticality does not meet the requirements.
[0006] Among them, the standard parts of special-shaped parts, shells and columns refer to standard parts with completely standardized structural dimensions.
[0007] If the detected irregular-shaped part does not meet the requirements, the operator will take out the irregular-shaped part and hit it with a wooden hammer to correct the deformed irregular-shaped part.
[0008] Among them, the outer wall of the shell of the special-shaped part to be detected is positioned by the opposite positioning block and the lateral positioning block. If the shell of the special-shaped part to be detected has a large deformation, the column to be detected still cannot enter the detection groove, or even if it enters the detection groove, it cannot be in surface contact with the circumferential inner wall of the detection groove.
[0009] The transverse pressing member may be an electric push rod, a cylinder, etc.
[0010] This solution uses the detection groove to detect whether the special-shaped parts to be inspected are deformed, so as to select defective products and avoid the special-shaped parts directly flowing into the machining workshop without being shaped, thereby causing the special-shaped parts after machining to be eccentric and scrapped.
[0011] Preferably, the upper end of the positioning seat is provided with a slide groove which is laterally open and extends transversely, and the detection member is slidably fitted in the slide groove.
[0012] The detection piece is slidably fitted in the slide groove to limit the vertical position of the detection piece, and can also limit the horizontal position of the detection piece, so that the detection piece can only move towards or away from the vertical pole to be detected, which makes the detection more accurate.
[0013] Preferably, the upper end of the positioning seat is provided with a clearance groove which is open upward and extends laterally, the clearance groove is located at the upper end of the slide groove and is connected with the slide groove, the width of the clearance groove is smaller than the width of the slide groove, the extension direction of the clearance groove is the same as that of the slide groove, and the detection member is provided with a handle extending upward, the handle passes upward through the clearance groove and extends above the upper end of the clearance groove.
[0014] The operator can move the detection piece conveniently by moving the handle in the clearance groove.
[0015] Preferably, the detection member is provided with an indicator line for displaying the position of the detection member.
[0016] The indicator line is used to indicate the specific position of the inspection part. When the inspection slot contacts the outer wall of the column of the special-shaped part to be inspected, the position of the indicator line can reflect whether the verticality of the column of the special-shaped part to be inspected meets the requirements and judge whether the special-shaped part is deformed. The extension direction of the indicator line is perpendicular to the extension direction of the chute.
[0017] Preferably, the detection member is provided with an observation groove which opens upward, and the extension direction of the observation groove is perpendicular to the extension direction of the slide groove. The connection between the groove wall of the observation groove away from the detection groove side and the upper end surface of the detection member constitutes the indicator line. When the groove wall of the observation groove away from the detection groove side is flush with the outer wall of the positioning seat, the verticality of the column to be detected meets the requirements.
[0018] The observation slot is upwardly open and extends in a direction perpendicular to the extension direction of the slide slot, so the observation slot is at least composed of slot walls close to and far from the detection slot and a slot bottom. There is a connection between the slot wall of the observation slot far from the detection slot and the upper end surface of the detection piece, and the connection forms an indicator line. The observation slot has a certain width, so that it is convenient for the operator to observe the detection piece, so as to determine whether the column to be detected and the special-shaped piece to be detected are deformed.
[0019] Preferably, the detection member is provided with a guide groove which is open laterally and penetrates vertically, the detection groove is communicated with the guide groove, the detection groove is located on the inner side of the guide groove, and the width of the guide groove is greater than the width of the detection groove.
[0020] The guide groove has a guiding function, and when the detection piece is close to the column to be detected, it is convenient for the column to be detected to enter the detection groove.
[0021] Preferably, the transverse clamping member includes a fixed block and a rotating member, the fixed block is fixed on the base plate, the rotating member is threadedly matched with the fixed block, the rotating member is arranged horizontally, and when the rotating member is screwed, the rotating member moves closer to or away from the shell of the special-shaped part to be detected.
[0022] When the rotating part is screwed, the rotating part will move horizontally, thereby pushing the housing of the irregular-shaped part to be inspected. The rotating part can be a bolt, which is cheaper than a cylinder or an electric push rod.
[0023] Preferably, a vertical pressing piece is provided on the bottom plate, and the vertical pressing piece is used to press the shell of the special-shaped part to be detected.
[0024] The pressing member can limit the upper and lower positions of the housing of the special-shaped part to be detected. The pressing member can be a pressing cylinder, a quick clamp, etc.
[0025] The utility model has the following advantages: the solution contacts the outer wall of the column of the special-shaped part to be detected through the detection groove, and observes the position of the indicator line at the same time, so as to judge whether the special-shaped part is deformed, so as to select defective products, and avoid the special-shaped parts directly flowing into the machining workshop without being shaped, thereby causing the eccentricity and scrapping of the special-shaped parts after machining.

A transverse clamping member is provided on the opposite side of the two opposite positioning blocks 11, and the transverse clamping member includes a fixed block 2 and a rotating member 21. The rotating member 21 is arranged horizontally and threadedly matched with the fixed block 2, and the rotating member 21 is screwed to make the rotating member 21 move horizontally. Three weight-reducing holes 3 that pass through the bottom plate 1 are provided. A vertical pressing member 8 for pressing the housing 100 of the to-be-detected special-shaped component is provided on the bottom plate 1 . The vertical pressing member 8 is any existing quick clamp.
[0034] like Figures 1 to 5 As shown, a positioning seat 4 extending upward is also provided on the bottom plate 1, and a slide groove 41 extending in the left-right direction and opening to the left is provided at the upper end of the positioning seat 4; a detection member 6 is slidably provided in the slide groove 41, and the detection member 6 is plate-shaped. A clearance groove 42 extending in the left-right direction and opening upward is provided at the upper end of the positioning seat 4, and the clearance groove 42 is located at the upper end of the slide groove 41 and is connected to the slide groove 41, and the width of the slide groove 41 is smaller than the width of the clearance groove 42. A matching hole 63 opening upward is provided on the detection member 6, and the handle 5 is threadedly matched with the matching hole 63, and the handle 5 passes through the clearance groove 42 upward and extends above the upper end of the clearance groove 42. Among them, the handle 5 is a bolt.
[0035] like Figures 3 to 5 As shown, the end of the detection member 6 away from the positioning seat 4 has a detection groove 61 that runs through it from top to bottom. The detection groove 61 opens to the left. The circumferential inner wall of the detection groove 61 is used to contact the circumferential outer wall of the upper end of the column to be detected. The cross-sectional shape of the circumferential inner edge of the detection groove 61 is the same as the cross-sectional shape of the circumferential outer edge of the upper end of the column standard part. Among them, the circumferential inner wall of the detection groove 61 has a taper of 3°, which is the same as the taper of the outer wall of the upper end of the column standard part. The end of the detection groove 61 away from the positioning seat 4 is also provided with a guide groove 62 that runs through it from top to bottom. The detection groove 61 is connected to the guide groove 62, and the width of the guide groove 62 is greater than the width of the detection groove 61. The detection groove 61 is located on the inner side of the guide groove 62.
[0036] like Figures 3 to 5As shown, the detection member 6 is provided with an observation groove 7 extending in the front-to-back direction and opening upward, the observation groove 7 has two left and right groove walls and a groove bottom, and an indicator line 72 is formed at the connection between the groove wall 71 of the observation groove 7 away from the detection groove and the upper end surface of the detection member 6. When the groove wall 71 away from the detection groove is flush with the side wall of the positioning seat 4, that is, the indicator line 72 is located at the groove opening of the slide groove 41, the verticality of the column to be detected meets the requirements, and the special-shaped part to be detected has not been deformed.
[0037] During the inspection process, the operator places the special-shaped part to be inspected on the base plate 1 so that the shell 100 of the special-shaped part to be inspected contacts the lateral positioning block 12, and then screws the rotating part 21 so that the rotating part 21 moves and presses against the shell 100 of the special-shaped part to be inspected, so that the circumferential outer wall of the shell 100 of the special-shaped part to be inspected contacts the opposite positioning block 11, and then presses the shell 100 of the special-shaped part to be inspected with the clamping part 8. After that, the operator moves the handle 5 so that the detection member 6 is close to the column 101 to be detected, and the detection groove 61 of the detection member 6 is close to the upper end of the column 101 to be detected. The operator observes whether the column 101 to be detected can successfully enter the detection groove 61. If the column 101 to be detected successfully enters the detection groove 61, the operator observes whether the column 101 to be detected is in surface-to-surface contact with the circumferential inner wall of the detection groove 61. If it is surface-to-surface contact, the operator observes whether the groove wall 71 away from the detection groove is flush with the side wall of the positioning seat 4. If it is flush, it means that the verticality of the column 101 to be detected meets the requirements and the special-shaped part has not been deformed. If it is found during the above detection that the column 101 to be detected does not meet the verticality requirements, it means that the special-shaped part has been deformed, and the special-shaped part is taken out and reshaped by hitting with a wooden hammer to correct the special-shaped part, and the detection is repeated after correction.
