Detailed Description
The above-described aspects are further described below in conjunction with specific embodiments. It should be understood that these examples are illustrative of the present application and are not limiting the scope of the present application. The implementation conditions employed in the examples may be further adjusted as in the case of the specific manufacturer, and the implementation conditions not specified are typically those in routine experiments.
The level difference detecting device (hereinafter referred to as level difference detecting device) proposed in the present application is described next with reference to the accompanying drawings.
As shown in fig. 1-4, the application includes a casing 1, wherein a cavity structure is formed inside the casing 1, a raised step 2 is arranged at one end of the casing 1, a through hole 21 is formed in the end face of the step 2, and the through hole 21 is communicated with the cavity structure.
As shown in fig. 1-4, a dial indicator 3 is disposed in the casing 1, the dial indicator 3 includes a measuring head 31, a connecting rod 32 and a gauge head 33, the measuring head 31 is used for contacting the surface of the measured object, and the connecting rod 32 converts the moving value into the rotation of the pointer on the gauge head 33 after generating linear motion, so as to read the size of the measured object. The dial indicator is a conventional technology, and the specific structure and working principle thereof are not described in detail herein. The gauge head 33 of the dial gauge 3 is partially arranged in the cavity structure, the connecting rod 32 is arranged in the through hole 21, and the gauge head 31 protrudes out of the end face of the step 2, so that the gauge head 31 can contact the surface of the measured object.
As shown in fig. 1-4, the standard component 4 is sleeved on the circumference of the connecting rod 32, is configured in the through hole 21 and partially protrudes out of the end face of the step 2. A first positioning hole 22 is formed in one side wall of the step 2, a second positioning hole 41 is correspondingly formed in the side wall of the standard component 4, and positioning pins (not shown) are inserted into the first positioning hole 22 and the second positioning hole 41, so that the standard component 4 is fixed relative to the shell 1. The height of the end face of the standard 4 from the end face of the step 2 is controlled by setting the height of the end face of the standard 4 from the second positioning hole 41. The distance between the end face of the standard component 4 and the end face of the step 2 is the standard height of the product sinking table.
As shown in fig. 1-4, the connecting rod 32 of the dial indicator 3 is further circumferentially sleeved with a fastener 5, and the fastener 5 adopts an elastic non-closed ring member to ensure locking connection between the fastener 5 and the dial indicator 3. A clamping hole 23 is formed in one side of the step 2 corresponding to the position of the fastener 5, a clamping piece (not shown) is arranged in the clamping hole 23 in a penetrating mode, and the clamping piece can be connected in the clamping hole 23 through threads. By screwing the clamping piece, the end of the clamping piece is propped against the fastening piece 5, and the fastening piece 5 and the dial indicator 3 are acted by force, so that the dial indicator 3 is fixed in the shell 1.
As shown in fig. 1 to 4, the gauge head 31 of the dial gauge 3 protrudes from the end surface of the standard 4, and the protruding height of the gauge head 31 with respect to the end surface of the standard 4 is set to a predetermined value. When in measurement, a sinking table of a product to be measured is attached to a height difference detection device, if the height difference of the product sinking table meets the standard, a concave surface of the sinking table pushes against a measuring head 31 to enable the measuring head 31 to descend to be flush with the end surface of a standard part 4, and if the concave surface of the sinking table is attached to the end surface of the standard part 4, namely the descending value of the measuring head 31 is equal to a fixed value, and the convex surface of the sinking table is attached to the end surface of a step 2, the product meets the standard; if the concave surface of the sinking platform is attached to the end surface of the standard component 4, namely the descent value of the measuring head 31 is equal to a fixed value, but the convex surface of the sinking platform is not attached to the end surface of the step 2, and a gap exists, the height difference of the sinking platform of the product is too small and does not meet the requirement; if the convex surface of the sinking table is attached to the end surface of the step 2 and the measuring head is not lowered to the height of the end surface of the standard component 4, that is, the lowering value of the measuring head 31 is smaller than the fixed value, the height difference of the sinking table is too large, and the product is not in accordance with the regulation.
