Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of centering measurement device, more particularly to a kind of electrode centering measurement tool. BACKGROUND
[0002] In the long-term operation, electrode rod is easily deformed under long-term stress, which leads to the failure of normal centering of upper and lower electrodes, i.e., the spot welding points of the upper and lower electrodes are not in the same center, and the deviation of the centering of the upper and lower electrodes is normally within 1 mm. If the deviation exceeds 1 mm, the contact area between the electrode and the workpiece to be welded is abnormal during welding, the current density is poor, and the welding strength is insufficient.
[0003] The existing measurement method usually adopts visual method, which is highly subjective, and the visual angle greatly affects the measurement size. Or the method of using ruler to measure, since the electrode outer periphery is arc surface, and cannot contact scale, still rely on level, error is bigger, cannot accurate measurement. UTILITY MODEL CONTENT
[0004] The utility model aims at overcoming the large measurement error of the centering of the upper and lower electrodes in the prior art, and provides an electrode centering measurement tool to accurately measure the centering of the upper and lower electrodes.
[0005] To solve the above technical problems, the utility model adopts the technical scheme of:
[0006] The utility model provides an electrode centering measurement tool, which comprises a measurement rest plate, a base, a measurement needle seat and a measurement needle. The measurement rest plate has an abutting surface for abutting with the electrode. The base is arranged on the measurement rest plate. The base is provided with a scale plate. The measurement needle seat is in sliding connection with the base. The measurement needle is arranged on the measurement needle seat. The end of the measurement needle close to the abutting surface is perpendicular to the tangent plane of the abutting surface relative to the first sliding direction of the base.
[0007] The utility model discloses an electrode centering degree measuring tool, when measuring the up and down electrode centering degree, the abutting surface of the measuring rest board is abutted on one of the electrodes, the measuring rest board is rotated around one of the electrodes, the end of the measuring needle close to the abutting surface is passed through the center of the two electrodes along the first sliding direction of the base, the measuring needle base is moved, the measuring needle base is slid in the base, the measuring needle is contacted with the other electrode, the reading is read on the scale board through the position of the measuring needle base, thereby the up and down electrode centering degree is accurately measured. Since the end of the measuring needle close to the abutting surface is passed through the center of the two electrodes along the first sliding direction of the base, and the first sliding direction of the base is perpendicular to the tangent plane of the abutting surface, the distance of the measuring needle movement is the maximum distance between the outer diameters of the up and down electrodes, since the radius of the up and down electrodes is equal, the maximum distance between the outer diameters of the up and down electrodes is equal to the center distance of the up and down electrodes, and the center distance of the up and down electrodes is the centering degree of the up and down electrodes, thereby the centering degree of the up and down electrodes can be obtained through the distance of the measuring needle movement. By abutting one of the electrodes through the measuring rest board, and abutting the other electrode through the measuring needle, the reading is read on the scale board through the position of the measuring needle base, thereby the up and down electrode centering degree is accurately measured.
[0008] Further, the abutting surface is an arc surface, and the first sliding direction is arranged along a radial direction of the arc surface. By arranging the abutting surface as an arc surface, the abutting surface can be more stably attached to the electrode, thereby more accurately measuring the up and down electrode centering degree.
[0009] Further, the measuring needle is arranged along the first sliding direction. When the measuring needle slides along the first sliding direction, the measuring needle moves along the axial direction of the measuring needle, thereby the centering degree of the up and down electrodes can also be obtained through the distance of the measuring needle beyond the tangent plane.
[0010] Further, the end of the measuring needle close to the abutting surface is a pointed end. By arranging the end of the measuring needle abutting the electrode as a pointed end, the measuring needle can be better abutted with the electrode.
[0011] Further, the utility model also includes an elastic member, two ends of the elastic member are connected with the base and the measuring needle base respectively, and the axial direction of the elastic member is arranged along the first sliding direction. By arranging the elastic member, the measuring needle can be kept abutting with the electrode during measurement, thereby facilitating accurate reading on the scale board.
[0012] Further, the scale board has a zero position, and when the elastic member is in a natural state, the measuring needle base is located at the zero position. By arranging the measuring needle base at the zero position when the elastic member is in the natural state, the measuring needle base can be automatically reset to the zero position when no measurement is performed, the elastic member is not stressed when the up and down electrode centering degree is qualified, and the elastic member is elongated or compressed when the up and down electrode centering degree has a deviation, thereby facilitating measurement of the up and down electrode centering degree.
[0013] Further, the scale board has a zero position, the width of the zero position is equal to the width of the measuring needle seat. When the measuring needle seat is located at the zero position, the measuring needle seat fully covers the zero position, and the centering degree of the upper and lower electrodes can be read by reading the distance of the measuring needle seat beyond the zero position on the left or right side.
[0014] Further, the length of the base is not greater than the length of the measuring backboard, and the width of the base is not greater than the width of the measuring backboard. By making the size of the base smaller than the size of the measuring backboard, the measuring backboard stably supports the base.
[0015] Further, the base is provided with a sliding rail, and the measuring needle seat is in sliding connection with the sliding rail. By arranging the sliding rail, the measuring needle seat can be stably slid in the base.
[0016] Further, the base is provided with a first limiting piece, the measuring needle seat is provided with a second limiting piece matched with the first limiting piece, and the second limiting piece is in sliding connection with the first limiting piece. By arranging the first limiting piece and the second limiting piece, the measuring needle seat is prevented from being separated from the base, so that the centering degree of the upper and lower electrodes can be measured at different angles.
[0017] Compared with the prior art, the electrode centering degree measuring tool has the following beneficial effects:
[0018] 1. The electrode centering degree measuring tool accurately measures the centering degree of the upper and lower electrodes by arranging the measuring backboard to abut against one of the electrodes, arranging the measuring needle to abut against the other electrode, reading the reading from the scale board according to the position of the measuring needle seat relative to the base, and reading the reading from the scale board.
[0019] 2. The electrode centering degree measuring tool has the following beneficial effects: the elastic piece is arranged to keep the measuring needle in abutment with the electrode during measurement, so that the reading from the scale board can be accurately read; the measuring needle seat is located at the zero position when the elastic piece is in a natural state, the measuring needle seat can be automatically reset to the zero position when measurement is not performed, the elastic piece is not stressed when the centering degree of the upper and lower electrodes is qualified, and the elastic piece is elongated or compressed when the centering degree of the upper and lower electrodes has a deviation, so that the centering degree of the upper and lower electrodes can be measured.

[0026] Embodiment one
[0027] The present embodiment is a first embodiment of an electrode centering degree measuring tool, as shown in Figure 1As shown, the electrode centering degree measuring tool comprises a measuring backplate 100, a base 200, a measuring needle holder 300 and a measuring needle 400. The measuring backplate 100 has an abutting surface 110 for abutting against an electrode. The base 200 is arranged on the measuring backplate 100. A scale plate 500 is arranged on the base 200. In this embodiment, the scale plate 500 is arranged on the upper surface of the base 200, which is convenient for a user to read. The measuring needle holder 300 is in sliding connection with the base 200. The measuring needle 400 is arranged on the measuring needle holder 300. The end of the measuring needle 400 close to the abutting surface 110 is perpendicular to the tangent plane of the abutting surface 110 relative to the first sliding direction of the base 200.
[0028] The measuring needle 400 is arranged along the first sliding direction. When the measuring needle 400 slides along the first sliding direction, the measuring needle 400 moves along the axial direction of the measuring needle 400, so that the centering degree of the upper and lower electrodes can also be obtained by measuring the distance of the measuring needle 400 beyond the tangent plane. Therefore, in this embodiment, the scale plate 500 can also be arranged on the measuring needle 400.
[0029] As shown in Figure 1 and Figure 2 , the scale plate 500 has a zero position 510. The width of the zero position 510 is equal to the width of the measuring needle holder 300. When the measuring needle holder 300 is located at the zero position 510, the measuring needle holder 300 fully covers the zero position 510. The scale plate 500 is provided with readings on both sides of the zero position 510. By reading the distance of the measuring needle holder 300 beyond the zero position 510 on the left or right side, the centering degree of the upper and lower electrodes can be read.
[0030] The working principle of the electrode centering degree measuring tool is as follows:
[0031] As shown in Figure 3As shown, when measuring the alignment of the upper and lower electrodes, the contact surface 110 of the measuring plate 100 is placed against one of the electrodes. The measuring plate 100 is rotated around one of the electrodes, so that the end of the measuring needle 400 near the contact surface 110 passes through the center of the two electrodes in the first sliding direction relative to the base 200. The measuring needle holder 300 is moved and slids in the base 200, so that the measuring needle 400 contacts the other electrode. The reading is read on the scale plate 500 according to the position of the measuring needle holder 300, thereby accurately measuring the alignment of the upper and lower electrodes. Since the first sliding direction of the end of the measuring needle 400 near the contact surface 110 relative to the base 200 passes through the centers of the two electrodes, and the first sliding direction of the end of the measuring needle 400 near the contact surface 110 relative to the base 200 is perpendicular to the tangent of the contact surface 110, the distance the measuring needle 400 moves is the maximum distance between the outer diameters of the upper and lower electrodes. Since the radii of the upper and lower electrodes are equal, the maximum distance between the outer diameters of the upper and lower electrodes is equal to the distance between the centers of the upper and lower electrodes. The distance between the centers of the upper and lower electrodes is the alignment of the upper and lower electrodes. Therefore, the alignment of the upper and lower electrodes can be obtained by measuring the distance the measuring needle 400 moves. By setting the measuring plate 100 to abut against one electrode and the measuring needle 400 to abut against the other electrode, the reading is taken from the scale plate 500 by measuring the position of the measuring needle seat 300 relative to the base 200, thereby accurately measuring the alignment of the upper and lower electrodes. Using this measuring tool, operation is convenient, the reading is intuitive and efficient, and the reference judgment is simple and clear, improving the accuracy of alignment measurement, thereby ensuring the strength and quality of spot welding.
[0032] This alignment measuring tool is not only suitable for measuring the alignment of upper and lower electrodes, but can also be directly applied to measuring the alignment between two cylinders of equal diameter. When measuring the alignment of two cylinders with unequal diameters, simply measure the diameters of both cylinders, perform a simple calculation after measurement, or adjust the scale on plate 500 to obtain the alignment of the two cylinders with unequal diameters. Therefore, this alignment measuring tool can be used to measure the alignment of any two objects.
[0033] Example 2
[0034] This embodiment is the second embodiment of the electrode pair moderate measurement tool. This embodiment is similar to the first embodiment, except that, as Figure 1 As shown, the contact surface 110 is an arc surface, and the first sliding direction is set radially along the arc surface. By making the contact surface 110 an arc surface, the contact surface 110 can more stably fit the electrode, thereby more accurately measuring the alignment of the upper and lower electrodes. In this embodiment, the arc surface of the contact surface 110 is consistent with the arc of the electrode, so that they fit together consistently during measurement.
[0035] The end of the measuring needle 400 close to the abutting surface 110 is provided with a pointed end 410. By providing the end of the measuring needle 400 abutting the electrode with the pointed end 410, the measuring needle 400 can better abut the electrode.
[0036] The length of the base 200 is not greater than the length of the measuring backboard 100, and the width of the base 200 is not greater than the width of the measuring backboard 100. By making the size of the base 200 smaller than the size of the measuring backboard 100, the measuring backboard 100 can stably support the base 200, and the tool as a whole is reinforced.
[0037] Embodiment Three
[0038] This embodiment is a third embodiment of the electrode centering degree measuring tool, which is similar to the first embodiment, except that it further comprises a resilient member, two ends of the resilient member are connected with the base 200 and the measuring needle holder 300 respectively, and the axial direction of the resilient member is along the first sliding direction. By providing the resilient member, the measuring needle 400 can abut the electrode during measurement, thereby facilitating accurate reading on the scale plate 500.
[0039] The scale plate 500 has a zero position 510, and when the resilient member is in a natural state, the measuring needle holder 300 is located at the zero position 510. By making the measuring needle holder 300 located at the zero position 510 when the resilient member is in a natural state, the measuring needle holder 300 can automatically reset to the zero position 510 when no measurement is performed. When the centering degree of the upper and lower electrodes is zero, the resilient member is not stressed, and the measuring needle 400 is not stressed in contact with the electrode. When the centering degree of the upper and lower electrodes has a deviation, the resilient member is elongated or compressed, thereby facilitating the measurement of the centering degree of the upper and lower electrodes.
[0040] In this embodiment, the resilient member can be provided at both ends of the measuring needle holder 300 and connected with the base 200, and the resilient member is provided as a spring. When the measuring needle 400 cannot contact the electrode, the measuring backboard 100 can be rotated to the opposite side or the measuring needle 400 can be manually pushed to contact the electrode.
[0041] Embodiment Four
[0042] This embodiment is a fourth embodiment of the electrode centering degree measuring tool, which is similar to the first embodiment, except that, as shown in Figure 1 The base 200 is provided with a sliding rail 210, and the measuring needle holder 300 is slidingly connected with the sliding rail 210. By providing the sliding rail 210, the measuring needle holder 300 can be stably slid in the base 200.
[0043] The base 200 is provided with a first limiting piece 220, the measuring needle seat 300 is provided with a second limiting piece 310 matched with the first limiting piece 220, and the second limiting piece 310 is in sliding connection with the first limiting piece 220. By arranging the first limiting piece 220 and the second limiting piece 310, the measuring needle seat 300 is prevented from being separated from the base 200, thereby facilitating the measurement of the centering degree of the upper and lower electrodes at different angles.
[0044] In the embodiment, the first limiting piece 220 is a protrusion, the second limiting piece 310 is a groove, and the protrusion is inserted into the groove. The first limiting piece 220 and the second limiting piece 310 not only prevent the measuring needle seat 300 from being separated from the base 200, but also guide the movement of the measuring needle seat 300 relative to the base 200. When the measuring needle seat 300 slides relative to the base 200, the groove moves under the guidance of the protrusion. Similarly, the first limiting piece 220 can be a groove, and the second limiting piece 310 can be a protrusion.
