Description

Technical Field

[0001] The utility model relates to the technical field of machine vision measurement equipment, and specifically relates to a probe replacement device with a quick replacement effect. Background Technique

[0002] When a machine vision measurement device performs contact measurement with a measurement pen, it is necessary to use the probe of the measurement pen to contact the object to be measured. This requires the probe to be firmly fixed to ensure the accuracy of the measurement. During measurement, in order to meet the materials of different objects to be measured, it is necessary to replace probes of different materials, and different-shaped probes also need to be replaced according to the shapes of different objects to be measured.

[0003] For example, the disclosed document with the application number 202322874167.8 discloses a probe replacement device. After the probe is inserted into the installation groove and needs to be locked, the locking member is moved in the direction away from the fixed part, so that the inner peripheral surface of the end of the locking member away from the fixed part fits with the outer peripheral surface of the end of the connecting part away from the fixed part, and the end of the connecting part away from the fixed part can be radially contracted, so that the inner side wall of the end of the connecting part away from the fixed part abuts against the outer side wall of the probe to be fixed. The probe is fixed to the fixed seat by the radial contraction and deformation of the end of the connecting part away from the fixed part; when the probe needs to be disassembled, the locking member is moved in the direction close to the fixed part, so that the inner peripheral surface of the end of the locking member away from the fixed part no longer fits with the outer peripheral surface of the end of the connecting part away from the fixed part, and the end of the connecting part away from the fixed part returns to its original state and no longer abuts against the outer side wall of the probe, facilitating the removal of the probe body; the installation and disassembly methods of the probe are simple, the installation speed is fast, the time for installing and disassembling the probe is reduced, the convenience of using the measurement device can be improved, and the work efficiency can be increased. The structure of the fixing device is simple, and the production cost can be reduced. However, for this probe replacement device, when disassembling and assembling the probe, it is necessary to gradually screw the thread, which affects the disassembly and assembly efficiency and is still not efficient and convenient enough for the disassembly and assembly of a large number of probes.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a probe replacement device with a quick replacement effect is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a probe replacement device with a quick replacement effect to solve the problems raised in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solution: A probe changing device with a quick replacement effect, including a fixed seat. A connecting ring is fixedly installed below the outer surface of the fixed seat. A slot is opened on the lower surface of the connecting ring. Four positioning rods are slidably penetrated and evenly distributed around the surface of the connecting ring. A spring is fixedly installed at the end of the surface of the positioning rod, and the end of the spring is fixedly connected to the connecting ring. An insertion ring is slidably inserted into the slot, and four positioning holes are evenly distributed around the surface of the insertion ring.

[0007] Preferably, the lower surface of one end of the positioning rod located inside the slot is set as an inclined surface, and one end of the positioning rod located inside the slot can be slidably inserted into the positioning hole.

[0008] Preferably, a sleeve ring is fixedly installed at the lower end of the insertion ring, and lugs are fixedly arranged on both the left and right sides of the outer surface of the sleeve ring.

[0009] Preferably, elastic pieces are fixedly installed on both the left and right sides of the bottom end of the fixed seat, and inclined heads are fixedly installed at the bottom ends of the elastic pieces.

[0010] Preferably, the expansion diameter of the elastic piece is larger than the inner diameter of the sleeve ring, and the diameter of the inclined head is slightly smaller than the inner diameter of the sleeve ring.

[0011] Preferably, a probe seat is inserted into the inner side of the elastic piece, and a probe head is fixedly arranged at the bottom end of the probe seat.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] 1. Through the settings of the elastic piece, the inclined head and the sleeve ring, after the probe seat is inserted into the elastic piece, the sleeve ring is sleeved and slid upward from the bottom. The inclined head can gradually squeeze the elastic piece to contract towards the middle, and then the sleeve ring is sleeved outside the elastic piece, squeezing and covering the entire elastic piece, so that the elastic piece tightly contracts and fits on the surface of the probe seat towards the inner side, fixing the entire probe seat. Due to the elastic tension of the elastic piece itself, it can expand towards the outside, thus fitting on the inner side surface of the sleeve ring, tensioning to make the sleeve ring not easily fall off, stably squeezing the elastic piece, effectively fixing and installing the probe seat, and being able to disassemble and assemble the probe head more quickly and conveniently without manual screwing and fixing, greatly improving the disassembly and assembly efficiency;

[0014] 2. The utility model provides a slot, a positioning rod, a spring, an insert ring and a positioning hole. When the sleeve moves up to squeeze the spring sheet, the insert ring will be inserted into the slot accordingly, and the positioning rod will be pushed to extend outward by the inclined surface. When the insert ring is fully inserted, the sleeve drives the insert ring to rotate so that the positioning hole can be aligned with the positioning rod. When the positioning hole is aligned with the positioning rod, the spring pulls the positioning rod to quickly insert into the positioning hole, thereby fixing the insert ring in the slot, and then the sleeve is further fixed to cover the outside of the spring sheet, making the sleeve more stable and not easy to fall off, thereby improving the stability of the entire probe seat and probe head installation in disguise.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 - 4 As shown, a measuring needle replacement device with a quick replacement effect includes a fixed seat 1, a connecting ring 2 is fixedly installed below the outer surface of the fixed seat 1, a slot 3 is opened on the lower surface of the connecting ring 2, four positioning rods 4 are evenly distributed and slidably penetrated around the surface of the connecting ring 2, a spring 5 is fixedly installed on the surface end of the positioning rod 4, the end of the spring 5 is fixedly connected to the connecting ring 2, an insert ring 9 is slidably inserted inside the slot 3, and four positioning holes 10 are evenly distributed around the surface of the insert ring 9.

[0022] Further, the lower surface of one end of the positioning rod 4 located inside the slot 3 is set as an inclined surface, and one end of the positioning rod 4 located inside the slot 3 can be slidably inserted into the positioning hole 10.

[0023] By adopting the above technical solution, the insertion ring 9 can be inserted into the slot 3 in a matching manner. During insertion, the inclined surface can be used to push the positioning rod 4 to protrude outward, so that the insertion ring 9 can be smoothly inserted into the slot 3; the positioning hole 10 matches the end of the positioning rod 4. When the positioning hole 10 is aligned with the positioning rod 4, the spring 5 can pull the positioning rod 4 to be stably inserted into the positioning hole 10 to fix the entire insertion ring 9.

[0024] Further, a collar 8 is fixedly installed at the lower end of the insertion ring 9, and lugs 11 are fixedly arranged on both the left and right sides of the outer surface of the collar 8.

[0025] By adopting the above technical solution, when the insertion ring 9 is fixed to the connecting ring 2, the position of the collar 8 can be fixed to prevent the collar 8 from falling off.

[0026] Further, elastic pieces 6 are fixedly installed on both the left and right sides of the bottom end of the fixed seat 1, and inclined heads 7 are fixedly installed at the bottom ends of the elastic pieces 6.

[0027] By adopting the above technical solution, the elastic piece 6 itself has an elastic force of expanding outward and can deform.

[0028] Further, the expansion diameter of the elastic piece 6 is larger than the inner diameter of the collar 8, and the diameter of the inclined head 7 is slightly smaller than the inner diameter of the collar 8.

[0029] By adopting the above technical solution, the collar 8 can be gradually moved upward by the inclined head 7 to contract the elastic piece 6. Due to the elastic tension of the elastic piece 6 itself, it can expand outward, so as to fit on the inner side surface of the collar 8 for tensioning, so that the collar 8 will not easily fall off and the collar 8 can stably press the elastic piece 6.

[0030] Further, a probe holder 12 is inserted and arranged inside the elastic piece 6, and a probe head 13 is fixedly arranged at the bottom end of the probe holder 12.

[0031] By adopting the above technical solution, when the elastic piece 6 is squeezed and contracted by the collar 8, it will press the probe holder 12 inward, thereby fixedly installing the probe holder 12 and the probe head 13.

[0032] Working principle: When using the probe changing device with fast replacement effect, first, insert the probe holder 12 inside the elastic piece 6. Then, the collar 8 is sleeved and slid upward from below. By using the inclined head 7, the elastic piece 6 can be gradually squeezed and contracted towards the middle, and then it is sleeved outside the elastic piece 6, squeezing and covering the whole elastic piece 6, so that the elastic piece 6 tightly contracts and fits on the surface of the probe holder 12, fixing the whole probe holder 12. Due to the elastic tension of the elastic piece 6 itself, it can expand outward, thus fitting on the inner side surface of the collar 8, making the collar 8 not fall off easily and stably squeezing the elastic piece 6 to effectively fix and install the probe holder 12. When the collar 8 moves upward to squeeze the elastic piece 6, the insertion ring 9 will correspondingly insert into the slot 3 inside. By using the inclined surface, the positioning rod 4 is pushed to extend outward. When the insertion ring 9 is completely inserted, rotate the collar 8 to drive the insertion ring 9 to rotate, so that the positioning hole 10 can be aligned with the positioning rod 4. When the positioning hole 10 is aligned with the positioning rod 4, the spring 5 will pull the positioning rod 4 to quickly insert into the positioning hole 10, thereby fixing the insertion ring 9 inside the slot 3, and further making the collar 8 more stably fixed and covered outside the elastic piece 6, so that the collar 8 is more stable and will not fall off easily. This is the working principle of the probe changing device with fast replacement effect.
