[0017] The present invention will be further described below with reference to the accompanying drawings.
[0018] As attached Figures 1 to 4 The clamping-type external shape measuring device includes a base plate 1, on which a support platform 2 is provided for placing the workpiece to be measured. A first slide block 3 and a second slide block 4 are respectively provided on both sides of the support platform 2, as shown in the attached figure. Figure 1As shown, the first slide 3 and the second slide 4 are located on the left and right sides of the support platform, respectively. A first measuring plate 5 is mounted on the first slide 3, and a second measuring plate 6 is mounted on the second slide 4. The first slide 3 and the second slide 4 can slide horizontally on the base plate 1 and laterally towards the support platform 2, so that the first measuring plate 5 and the second measuring plate 6 are clamped on the lateral sides of the workpiece to be measured, i.e., the left and right sides. A horizontal scale 7 is provided on the base plate 1, which displays the lateral distance between the first measuring plate 5 and the second measuring plate 6. When the first measuring plate 5 and the second measuring plate 6 are clamped on the left and right sides of the workpiece to be measured, the lateral distance between them is the width of the workpiece.
[0019] The first measuring plate 5 has a third slide 8 and a fourth slide 9 on the side facing away from the support platform 2, as shown in the attached figure. Figure 1 As shown, the third slide 8 and the fourth slide 9 are located on the upper and lower sides of the support platform 2, respectively. The third slide 8 has a third measuring plate 10, and the fourth slide 9 has a fourth measuring plate 11. The first measuring plate 5 and the second measuring plate 6 are vertical plates, while the third measuring plate 10 and the fourth measuring plate 11 are horizontal plates. The third slide 8 and the fourth slide 9 can slide up and down on the first measuring plate 5, so that the third measuring plate 10 and the fourth measuring plate 11 are clamped on the vertical sides of the workpiece to be measured, i.e., the upper and lower sides. A vertical scale 12 is provided on the first measuring plate 5, which displays the height difference between the third measuring plate 10 and the fourth measuring plate 11. When the third measuring plate 10 and the fourth measuring plate 11 are clamped on the upper and lower sides of the workpiece to be measured, the height difference between the third measuring plate 10 and the fourth measuring plate 11 is the height of the workpiece to be measured.
[0020] A transverse slide rail 13 is provided on the base plate 1, and the first slide block 3 and the second slide block 4 are movably mounted on the transverse slide rail 13. A vertical slide rail 14 is provided on the side of the first measuring plate 5 facing away from the support platform 2, and the third slide block 8 and the fourth slide block 9 are movably mounted on the vertical slide rail 14. A locking mechanism 15 is provided between each slide block and the corresponding slide rail. The locking mechanism 15 can fix the slide block on the corresponding slide rail, thereby fixing the position of the measuring plate so as to accurately read the scale reading and obtain the external dimensions of the part to be measured.
[0021] The horizontal scale 7 is positioned adjacent to the horizontal slide rail 13. Indicator rods 16 are connected to the lower parts of both the first measuring plate 5 and the second measuring plate 6. The indicator rods 16 point downwards towards the horizontal scale 7, and there is a certain gap between the bottom end of the indicator rod 16 and the upper surface of the horizontal scale 7 to prevent friction between them. The indicator rods 16 allow for more accurate measurement of the scales corresponding to the first measuring plate 5 and the right measuring element.
[0022] In one embodiment, two transverse slide rails 13 are arranged side by side on the base plate 1, and the two transverse slide rails 13 are parallel to each other. A first slide block 3 and a second slide block 4 are respectively mounted on the two transverse slide rails 13, and two transverse scales 7 are respectively arranged adjacent to the two transverse slide rails 13, with the scales of corresponding areas of the two transverse scales 7 being consistent. Therefore, the scale readings corresponding to the first measuring plate 5 and the second measuring plate 6 can be read respectively, and then the two scale readings can be subtracted to obtain the distance between the first measuring plate 5 and the second measuring plate 6.
[0023] The vertical scale 12 is disposed on one side surface of the first measuring plate 5, and the side of the first measuring plate 5 on which the vertical scale 12 is disposed is referred to as the scale surface 17. The third measuring plate 10 has an indicator groove 18, and an insert rod is formed at the upper end of the first measuring plate 5, which slides into the indicator groove 18. The shape of the insert rod matches the shape of the indicator groove 18, and the cooperation between the insert rod and the indicator groove 18 ensures that the third measuring plate 10 is horizontal. The opening of the indicator groove 18 is flush with the scale surface 17, facilitating the reading of the scale corresponding to the lower surface of the third measuring plate 10.
[0024] The fourth measuring plate 11 is a horizontal plate, comprising a base plate portion 19 and a clamping plate portion 20. The base plate portion 19 is fixed on the fourth slide block 9, and one side of the base plate portion 19 is spaced apart from the scale surface 17 to facilitate reading the scale corresponding to the upper surface of the base plate portion 19. The clamping plate portion 20 is connected to the base plate portion 19 in a bent shape and extends towards the first slide block 3. When the workpiece to be measured is placed on the support platform 2, the clamping plate portion 20 can extend under the workpiece to allow the third measuring plate 10 and the fourth measuring plate 11 to cooperate and clamp on the upper and lower sides of the workpiece.
[0025] In one embodiment, a plurality of positioning posts 21 are provided on the support platform 2, and the part to be measured has a positioning groove that cooperates with the positioning posts 21, so that the positioning posts 21 can be positioned and cooperate with the part to be measured to position the part to be measured on the support platform 2.
[0026] Handles 22 are installed on both sides of the base plate 1, which facilitates the handling of the entire measuring device.
[0027] In one embodiment, the locking mechanism 15 is as shown in the attached figure. Figure 4 As shown, the slide includes multiple pulleys located at the bottom of the slide block. The lateral spacing between the pulleys can be adjusted by a knob. When the lateral spacing between adjacent pulleys increases, the adjacent pulleys press against both sides of the slide rail, thereby locking the slide block onto the slide rail. When the lateral spacing between adjacent pulleys decreases, the slide block and the slide rail are in clearance fit.
[0028] When the locking mechanism 15 is not locking the slide, there will be a certain gap between the slide and the corresponding slide rail. Due to the gap, the slide is more likely to slide on the slide rail. When the locking mechanism 15 locks the slide, the slide and the slide rail are tightly pressed together, and the measuring plate on the slide is perpendicular to the corresponding slide rail.
[0029] When measuring the width of the part to be measured, the first slide block 3 and the second slide block 4 need to slide on the transverse slide rail 13. At this time, the first slide block 3 and the second slide block 4 are in an unlocked state. Since the slide block and the corresponding slide rail are in a clearance fit when unlocked, it cannot be guaranteed that the measuring plate and the corresponding slide rail are perpendicular to each other. Under such circumstances, the data measured by the measuring plate may be deviated, affecting the measurement accuracy of the shape of the part to be measured.
[0030] Therefore, in this invention, a guide plate 23 is also provided on the fourth slide 9. The guide plate 23 is parallel to the fourth measuring plate 11 and located below the fourth measuring plate 11. The clamping portion 20 of the fourth measuring plate 11 is located above the second slide 4. When the fourth slide 9 moves down until the guide plate 23 presses against the base plate 1, the clamping portion 20 of the fourth measuring plate 11 presses against the second slide 4.
[0031] When measuring, follow these steps:
[0032] Step S1: Place the part to be measured on the support platform 2;
[0033] Step S2: Control the corresponding locking mechanism 15 to release the first slide 3, the second slide 4 and the fourth slide 9, and then let the fourth slide 9 move down along the vertical guide rail until the guide plate 23 presses against the base plate 1. At this time, the clamping part 20 of the fourth measuring plate 11 also presses against the second slide 4.
[0034] Step S3: Keep the guide plate 23 pressed against the base plate 1, and then lock the fourth slide 9. After locking the fourth slide 9, the fourth measuring plate 11 and the guide plate 23 are perpendicular to the first measuring plate 5. Therefore, the guiding effect generated by the cooperation of the guide plate 23 and the base plate 1 can keep the first slide 3 in a horizontal state, and correspondingly, the first measuring plate 5 in a vertical state. The guiding effect generated by the fourth measuring plate 11 and the second slide 4 can keep the second slide 4 in a horizontal state, and correspondingly, the second measuring plate 6 in a vertical state. This can improve the dimensional measurement accuracy of the workpiece.
[0035] Step S4: Move the first slide block 3 and the second slide block 4 so that the first measuring plate 5 and the second measuring plate 6 are clamped on the left and right sides of the workpiece to be measured. Then lock the first slide block 3 and the second slide block 4. Obtain the distance between the first measuring plate 5 and the second measuring plate 6 through the horizontal scale 7, and then obtain the width of the workpiece to be measured.
[0036] Step S5: Loosen and move the third slide 8 and the fourth slide 9 so that the third measuring plate 10 and the fourth measuring plate 11 are clamped on the upper and lower sides of the part to be measured. Then lock the third slide 8 and the fourth slide 9. Obtain the distance between the third measuring plate 10 and the fourth measuring plate 11 through the vertical scale 12, and then obtain the height of the part to be measured.
[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
