Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a positioning mechanism for detecting an automatic control instrument of an electric instrument. Background Technique

[0002] An electric automation instrument is composed of several automation components and is an automation technical tool with relatively perfect functions. It generally has several functions at the same time, such as measurement, display, recording or measurement, control, alarm, etc. The automation instrument itself is a system and also a subsystem in the whole automation system. The automation instrument is an "information machine", and its main function is the conversion of information forms, converting the input signal into an output signal. The signal can be expressed in the time domain or frequency domain, and the transmission of the signal can be modulated into a continuous analog form or a discontinuous digital form. When an electric automation instrument is produced, it is necessary to detect the instrument to check whether it is qualified.

[0003] When some existing electric instruments are detected, some dust is easily attached to their surfaces. Therefore, the operator needs to use a cleaning device to pre-clean the electric instruments before detection, and then the detection can be carried out. Therefore, it is more troublesome to detect electric instruments. For this reason, we propose a positioning mechanism for detecting an automatic control instrument of an electric instrument to solve the above-mentioned problems. Content of the Utility Model

[0004] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments.

[0005] Therefore, the purpose of the utility model is to provide a positioning mechanism for detecting an automatic control instrument of an electric instrument, which can solve the problem that when some existing electric instruments are detected, some dust is easily attached to their surfaces. Therefore, the operator needs to use a cleaning device to pre-clean the electric instruments before detection, and then the detection can be carried out. Therefore, it is more troublesome to detect electric instruments.

[0006] To solve the above technical problems, the utility model provides a positioning mechanism for detecting an automatic control instrument of an electric instrument, and adopts the following technical scheme: it includes a calibration mechanism, which includes a base, a detection box is fixedly arranged on the top surface of the base, an electric push rod is fixedly arranged on the top surface of the base, a placement plate is fixedly arranged at the extending end of the electric push rod, an assembly groove is horizontally opened along the width of the placement plate, a gear rod is rotatably arranged in the assembly groove, calibration parts are movably sleeved at both ends of the two gear rods, a toothed plate is fixedly arranged on the top surface of the base, and the toothed plate meshes with the gear rod;

[0007] A purging mechanism, which includes a contact rod fixedly arranged on one side of the calibration member facing the detection box. A hollow plate corresponding to the contact rod is fixedly arranged in the detection box. A gas pushing member is movably arranged in the hollow plate. A purging member for purging the electrical instrument is fixedly arranged on the side surface of the hollow plate. The air inlet end of the purging member is communicated with the inner wall of the hollow plate. When the electric push rod pushes the calibration member to move into the detection box, the contact rod is inserted into the hollow plate and abuts against the gas pushing member.

[0008] By adopting the above technical solution, in this solution, the electrical instrument is first placed on the placement plate, and then the placement plate is pushed to move by the electric push rod, so as to push the electrical instrument into the detection box for detection.

[0013] Optionally, the gear rod includes a rod body and a transmission gear. The rod body includes two thread segments with opposite thread directions. The transmission gear is fixedly sleeved in the middle of the outer wall of the rod body, and the transmission gear meshes with the toothed plate.

[0014] By adopting the above technical solution, in this solution, when the electric push rod pushes the placement plate to move, the toothed plate drives the transmission gear to rotate and prompts the two calibration members to move towards the placement plate at the same time, and then the calibration members abut against the electrical instrument.

[0015] Optionally, the correction member includes an internally threaded ring and two connecting plates. The internally threaded ring is movably sleeved on the rod body and is threadedly connected to the rod body.

Opposite ends of the two connecting plates are perpendicularly and fixedly provided with L-shaped plates. The internally threaded ring and the connecting plates are both located in the assembly groove and are slidably engaged with the inner wall of the assembly groove.

[0016] By adopting the above technical solution, in this solution, when the toothed plate drives the transmission gear to rotate, the internally threaded ring drives the connecting plates and the L-shaped plates to move, and then the position of the electrical instrument is corrected by the contact between the L-shaped plate and the electrical instrument.

The air-pushing member includes a piston plate and a compression spring. The piston plate is movably arranged in the hollow plate.

[0022] By adopting the above technical solution, in this solution, when the piston plate moves, the air in the hollow plate is pushed into the supply air pipe through the circular pipe, and then the air flow is ejected through the nozzles.

[0023] In summary, the present utility model has at least one of the following beneficial effects:

[0024] When the storage plate moves, the resistance rod is inserted into the hollow plate and pushes the air pusher to move. At this time, the air pusher pushes the airflow in the hollow plate into the purge part, and then the purge part sprays airflow to purge the dust on the surface of the electrical instrument, thereby reducing the impact of dust on the accuracy of electrical instrument detection, and making it easier to clean the dust on the surface of the electrical instrument;

[0034] The following will further elaborate on the present utility model in conjunction with the attached drawings. Figures 1-5 A further detailed description of the present utility model will be given below.

[0035] Embodiment 1. Referring to Figures 1-5 , in this embodiment, in order to solve the problem that when some existing electrical instruments are being detected, dust is likely to adhere to their surfaces, so the operator needs to use cleaning equipment to pre-clean the electrical instruments before detection, which makes the detection of electrical instruments rather troublesome. The present utility model discloses a positioning mechanism for the automated self-control instrument detection of electrical instruments.

[0036] It includes a calibration mechanism 100, which includes a base 101. A detection box 102 is fixedly arranged on the top surface of the base 101. An electric push rod 103 is fixedly arranged on the top surface of the base 101. A placement plate 104 is fixedly arranged at the extending end of the electric push rod 103. A detector 102a is fixedly arranged on the inner top wall of the detection box 102. An opening for the placement plate 104 to enter is formed at one end of the detection box 102 facing the placement plate 104. Through the opening, it is convenient for the electric push rod 103 to push the placement plate 104 to move, thereby pushing the electrical instrument into the detection box 102. Through the detector 102a, it is convenient to detect the electrical instrument that enters the detection box 102.

[0037] A sealing plate 104a is fixedly arranged at one end of the placement plate 104 away from the detection box 102. The sealing plate 104a is fixedly connected to the extending end of the electric push rod 103. When the electric push rod 103 pushes the placement plate 104 to move, the sealing plate 104a fits with the opening of the detection box 102. When the placement plate 104 moves into the detection box 102, the sealing plate 104a blocks the opening of the detection box 102, thereby reducing the possibility of external debris entering the detection box 102 and affecting the detection accuracy of the electrical instrument.

[0038] An assembly groove 105 is horizontally formed along the width of the placement plate 104. A gear rod 106 is rotatably arranged in the assembly groove 105. Through the assembly groove 105, it is convenient to assemble the gear rod 106. Both ends of the two gear rods 106 are movably sleeved with calibration members 107. A toothed plate 108 is fixedly arranged on the top surface of the base 101. The toothed plate 108 meshes with the gear rod 106. When the placement plate 104 moves, the gear rod 106 is driven to rotate by the toothed plate 108 and the two calibration members 107 are simultaneously moved towards the placement plate 104 direction, and then the calibration members 107 are brought into contact with the electrical instrument.

[0039] The purge mechanism 200 includes a resistance rod 201 fixedly arranged on the side of the correction member 107 facing the detection box 102, a hollow plate 202 corresponding to the resistance rod 201 is fixedly arranged in the detection box 102, and an air pusher 203 is movably arranged in the hollow plate 202. As the storage plate 104 moves, the resistance rod 201 is inserted into the hollow plate 202 and pushes the air pusher 203 to move.

[0040] A purge member 204 for purging electrical instruments is fixedly arranged on the side of the hollow plate 202. A jack for inserting the abutment rod 201 into the hollow plate 202 is provided at one end of the hollow plate 202 facing the storage plate 104. The air pusher 203 includes a piston plate 203a and a compression spring 203b. The piston plate 203a is movably arranged in the hollow plate 202. One side of the piston plate 203a abuts against the abutment rod 201. The other side of the piston plate 203a abuts against the abutment rod 201 through the compression spring 203b. The inner wall of the hollow plate 202 is connected. When the resistance rod 201 is inserted into the hollow plate 202 through the socket, the resistance rod 201 pushes the piston plate 203a to move and pushes the air in the hollow plate 202 into the purge part 204, and as the piston plate 203a moves, the compression spring 203b is compressed and deformed. When the resistance rod 201 is separated from the piston plate 203a, the piston plate 203a loses thrust, and the compression spring 203b recovers its deformation and pushes the piston plate 203a to return to its original position.

[0041] The air inlet end of the purge member 204 is connected to the inner wall of the hollow plate 202. When the electric push rod 103 pushes the correction member 107 to move into the detection box 102, the abutment rod 201 is inserted into the hollow plate 202 and abuts against the air pushing member 203. The purge member 204 includes an air supply pipe 204a. The inner wall of the air supply pipe 204a is connected to the inner wall of the hollow plate 202 through a circular tube. A plurality of nozzles 204b are fixedly connected to the bottom surface of the air supply pipe 204a facing one end of the storage plate 104. When the piston plate 203a moves, the air in the hollow plate 202 is pushed into the air supply pipe 204a through the circular tube, and then the airflow is ejected through the nozzle 204b. The ejected airflow facilitates the purge of dust on the electrical instrument.

[0042] The specific working principle is: as the placement plate 104 moves, the resistance rod 201 is inserted into the hollow plate 202 and pushes the air pushing member 203 to move. At this time, the air pushing member 203 pushes the airflow in the hollow plate 202 into the purge member 204, and then the purge member 204 sprays airflow to purge the dust on the surface of the electrical instrument, thereby reducing the impact of dust on the accuracy of electrical instrument detection, and making it easier to clean the dust on the surface of the electrical instrument.

[0043] Example 2, refer to Figures 1-3, in this embodiment, in order to solve the problem that the positioning of some existing detection devices is relatively troublesome, based on the same concept as in the above-mentioned first embodiment, this positioning mechanism for the automatic control instrument detection of electrical instruments further includes:

[0044] The gear rod 106 includes a rod body 106a and a transmission gear 106b. The rod body 106a includes two threaded sections with opposite thread directions. The transmission gear 106b is fixedly sleeved in the middle of the outer wall of the rod body 106a. The transmission gear 106b meshes with the toothed plate 108. When the electric push rod 103 pushes the placement plate 104 to move, the toothed plate 108 drives the transmission gear 106b to rotate and prompts the two correction members 107 to move towards the placement plate 104 at the same time, and then the correction members 107 are in contact with the electrical instrument, so as to facilitate the correction of the position of the electrical instrument.

[0045] The correction member 107 includes an internal thread ring 107a and two connecting plates 107b. The internal thread ring 107a is movably sleeved on the rod body 106a and is threadedly connected to the rod body 106a. The relative ends of the two connecting plates 107b are fixedly connected to the outer wall of the internal thread ring 107a. The opposite ends of the two connecting plates 107b are vertically and fixedly provided with L-shaped plates 107c. The internal thread ring 107a and the connecting plates 107b are both located in the assembly groove 105 and are slidably matched with the inner wall of the assembly groove 105. When the toothed plate 108 drives the transmission gear 106b to rotate, the internal thread ring 107a drives the connecting plates 107b and the L-shaped plates 107c to move, and then the L-shaped plates 107c are in contact with the electrical instrument to facilitate the correction of the position of the electrical instrument.

[0046] The specific working principle is: First, place the electrical instrument on the placement plate 104, and then push the placement plate 104 to move through the electric push rod 103, so as to push the electrical instrument into the detection box 102 for detection. When the placement plate 104 moves, the toothed plate 108 drives the gear rod 106 to rotate and prompts the two correction members 107 to move towards the placement plate 104 at the same time, and then the correction members 107 are in contact with the electrical instrument, so as to facilitate the correction of the position of the electrical instrument.

[0047] Embodiment Three, referring to Figures 2-3 , in this embodiment, in order to solve the problem that it is relatively troublesome to fix the electrical instrument when some existing detection devices detect the electrical instrument, based on the same concept as in the above-mentioned first embodiment, this positioning mechanism for the automatic control instrument detection of electrical instruments further includes:

[0048] A slide groove 107d is vertically provided on the side of the L-shaped plate 107c facing the storage plate 104, and a pressure plate 107e is movably provided in the slide groove 107d. The bottom surface of the pressure plate 107e is connected to the inner bottom wall of the slide groove 107d by setting a spring 107f. The edge of the lower end of the hollow plate 202 facing the storage plate 104 is rounded. When the storage plate 104 moves into the detection box 102, the hollow plate 202 contacts the pressure plate 107e so that the pressure plate 107e is pressed. The plate 107e moves downward, and the slide groove 107d facilitates the assembly of the pressure plate 107e, and the spring 107f pushes the pressure plate 107e to move upward. As the hollow plate 202 moves into the detection box 102, the hollow plate 202 contacts the pressure plate 107e and pushes the pressure plate 107e to move downward, so that the electrical instrument is fixed on the storage plate 104 through the pressure plate 107e, thereby reducing the possibility of position displacement of the electrical instrument during detection.

[0049] The specific working principle is: as the hollow plate 202 moves into the detection box 102, the hollow plate 202 contacts the pressing plate 107e and pushes the pressing plate 107e to move downward, thereby fixing the electrical instrument on the storage plate 104 through the pressing plate 107e.

[0050] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
