Detailed Description
In the present application, the terms "front", "rear", "upper", "lower", and the like are used to describe the directions shown in the drawings. It should be understood that the above directional terms are described for clearly indicating the relative position relationship of the technical solutions of the present application, and the arrangement of the products carrying the technical solutions of the present application may not be limited to the directional relationships shown in the drawings of the present application, so the above directional terms do not limit the protection scope of the present application.
The technical solution of the present application will be described in detail below with reference to the accompanying drawings.
In the conventional measuring apparatus, particularly in the case where a plurality of measuring heads are arranged, it is often necessary to coordinate the positional relationship between the plurality of measuring heads, and if an operator performs a measuring operation that violates an operation rule, damage to the measuring apparatus is likely to occur due to lack of a protection function against erroneous operation.
To address at least some of the above issues, the present application provides a measuring device with an interlock mechanism, as shown in fig. 1, comprising: a base 10, wherein the base 10 is fixedly arranged on the frame and is provided with a workbench 11 for arranging the part S to be measured; a first contact assembly 12 and a second contact assembly 13, the first contact assembly 12 and the second contact assembly 13 being spaced from each other and movably disposed to the base 10, the first contact assembly 12 and the second contact assembly 13 each having an approaching position approaching the table 11 for making measurements and a remote position away from the table 11 for not making measurements; an interlock mechanism arranged in the base 10 and associated with the first and second contact assemblies 12, 13, such that only in a state in which one of the first and second contact assemblies 12, 13 is in its proximate position, the other of the first and second contact assemblies 12, 13 can take a measurement.
According to the technical scheme of the application, one of the first contact assembly 12 and the second contact assembly 13 can be in the state of the approach position, and the other of the first contact assembly 12 and the second contact assembly 13 can be moved into the approach position to carry out the measurement operation. In other words, if one of the first and second contact assemblies 12, 13 is in a remote position where it does not take a measurement, the other of the first and second contact assemblies 12, 13 cannot enter into a proximate position where it takes a measurement. Therefore, through the arrangement of the interlocking mechanism, the working position relationship between the first contact assembly 12 and the second contact assembly 13 is correlated, so that even if an operator has operation errors, the first contact assembly 12 and the second contact assembly 13 of the measuring device can automatically prevent the measuring contact from mistakenly contacting the workpiece S to be measured through the interlocking mechanism, and the safety of the measuring device is improved.
The base 10 is fixedly arranged on the frame or is a part of the frame. The working platform 11 of the base 10 is generally horizontally arranged as shown in fig. 1, but the application is not limited thereto, and the working platform 11 may be vertically arranged in some working occasions. The table 11 may be provided with a clamp for releasably clamping the part S to be measured.
The first contact assembly 12 and the second contact assembly 13 may both be used for detecting a predetermined parameter for measurement, or may be designed such that one is used for measurement purposes and the other is used for positioning purposes. In the case of both operating conditions for measuring the predetermined parameter, the above-described interlocking mechanism can be used, for example, such that the first contact assembly 12 is brought into the proximity position in which the measurement is to be carried out, and the second contact assembly 13 is brought into its proximity position, so that the predetermined parameter can be measured in two different ways one after the other.
According to the solution of the present application, as shown in fig. 2, one of the first contact assembly 12 and the second contact assembly 13 is preferably used for measurement, and the other is used for positioning the workpiece to be measured. For example, the first contact assembly 12 is used for positioning a workpiece to be measured, the second contact assembly 13 is used for measuring the workpiece to be measured, and when the first contact assembly 12 positions the workpiece to be measured at the approaching position, the second contact assembly 13 can enter the approaching position to measure the workpiece to be measured; when the first feeler assembly 12 is in a remote position from the table 11, the workpiece to be measured is not positioned correctly, the interlocking mechanism acts on the second feeler assembly 13 to make it unable to enter the access position, so as to prevent the damage of the measuring head due to the wrong operation.
The first contact assembly 12 and the second contact assembly 13 may each be movably disposed on the table 11, and disposed at a distance from each other so that no interference occurs therebetween during the respective movements. The moving directions of the first contact assembly 12 and the second contact assembly 13 may be the same as each other or may be different from each other. For example, in the preferred embodiment of the present application, as shown in fig. 1 and 2, the base 10 includes a vertical portion 14 fixedly connected to the table 11, the first contact assembly 12 is disposed on the table 11 to be movable back and forth, the second contact assembly 13 is disposed on the vertical portion 14 to be movable vertically up and down, and the second contact assembly 13 is located above the first contact assembly 12. Through the arrangement mode, the first contact assembly 12 and the second contact assembly 13 hardly generate interference in the moving mode, so that not only can the height space be fully utilized and the horizontal space be saved, but also the measuring device of the application can have higher integration compactness. In this condition, the interlock mechanism may correlate the horizontal back and forth movement of the first contact assembly 12 with the vertical up and down movement of the second contact assembly 13. For example, the second contact assembly 13 can only be moved up or down into the measuring position when the first contact assembly 12 is moved forward or backward to the corresponding position.
In the technical solution of the present application, the interlocking mechanism may be implemented in various ways. For example, the interlock mechanism may be an electrical automatic interlock mechanism, which is realized by the design of the electrical control device of the first contact assembly 12 and the second contact assembly 13; or the interlocking mechanism can be realized by a hydraulic mechanism; or may be interlocked by means of a mechanical structure, which will be described in detail below.
The movement of the first contact assembly 12 described above may be controlled by a linear drive mechanism such as an air cylinder, or to reduce the cost of the measuring device, the movement of the first contact assembly 12 may be controlled manually. Preferably, the measuring device includes a first manual actuation mechanism mechanically coupled to the first contact assembly 12 to reciprocate the first contact assembly 12 in a forward-rearward direction between its proximate and distal positions. The first manual actuation mechanism may be a handle fixedly connected to the first contact assembly 12, and the first contact assembly 12 is directly pushed or pulled to reciprocate between the approaching position and the distant position thereof by manually manipulating the handle; or the first manual actuating mechanism can be provided with a switching mechanism such as a lever and/or a ramp structure which can function to save labor and/or change the direction of force, so as to provide a manual braking mechanism which is labor-saving and convenient to operate. Preferably, the first manual actuation mechanism comprises a manual operation portion 15, and the manual operation portion 15 is located on a side of the table 11. The manual operation section 15 is provided on the side of the table 11, so that the manual operation by the operator can be facilitated.
As shown in fig. 3 and 4, the first contact assembly 12 may preferably include a first bracket 121 and a positioning contact 122 fixedly disposed on the first bracket 121, and the first bracket 121 may be disposed on the table 11 to be movable back and forth. An operator manually operates the first manual actuating mechanism, so that the first support 121 moves back and forth on the workbench 11, and the positioning contact 122 fixedly arranged on the first support 121 approaches to or departs from a workpiece to be measured. When the positioning contact 122 is in the approaching position, the positioning contact abuts against the workpiece to be measured, so that the positioning contact 122 can be accurately positioned relative to the workpiece to be measured. For example, when the workpiece to be measured is a gear, the positioning contact 122 may be engaged with the tooth slot to prevent the gear from rotating during the measurement process; or, a positioning structure, such as a positioning hole, for matching with the positioning contact is preset on the workpiece to be measured.
Preferably, the first bracket 121 passes through the lower part of the part S to be measured from the front of the part S to be measured and extends to between the part S to be measured and the vertical part 14, so that the layout space is saved, the integration compactness of the measuring device is improved, the positioning contact 122 can face the part S to be measured at the rear of the part S to be measured, the positioning contact 122 is arranged close to the second contact assembly 13, and the matching degree of the positioning contact 122 and the second contact assembly 13 is increased so as to improve the measuring precision of the measuring device. Wherein, all set up locating contact 122 and second contact subassembly 13 and be located the rear of part S that awaits measuring, can make operating personnel conveniently observe measuring device' S operating condition in the operation process.
As shown in fig. 5, the second contact assembly 13 includes: a slide table 131 provided vertically movably to the vertical portion 14 and a measurement contact 132 mounted on the slide table 131 and arranged downward. A slide rail is preferably disposed between the sliding table 131 and the vertical portion 14, so that the sliding table 131 can slide on the vertical portion 14 along the slide rail direction by means of the slide rail matching. The measurement probe 132 may be a sensor or a probe that interacts with a sensor to directly contact the workpiece to be measured.
According to the first contact assembly 12 and the second contact assembly 13, the following manner is realized through the interlocking mechanism: when the positioning contact 122 is in the close position to contact and position the workpiece, the operator can control the measuring contact 132 to approach or contact the workpiece to be measured for measurement; when the positioning contact 122 is located at a far position far away from the workpiece to be measured, the operator cannot control the measuring contact 132 to be close to the workpiece to be measured through the locking of the interlocking mechanism, so that the error rate of manually controlling the measuring device is reduced. Wherein the interlocking mechanism preferably comprises a locking mechanism 16 arranged adjacent the measurement feeler 132 in the vertical portion 14, as shown in fig. 5, which locking mechanism 16 is adapted to releasably lock the measurement feeler 132. In order for the latch mechanism 16 to be released only when the first contact assembly 12 is in its proximate position, the latch mechanism 16 may be a latch device, such as a proximity switch control, that associates the proximity switch with the moving position of the first contact assembly 12; or the locking mechanism 16 may be a mechanical locking mechanism whereby the mechanical structure extending through the first contact assembly 12 interferes with the mechanical structure extending through the second contact assembly 13 to effect movement of the second contact assembly 13 to its proximate position only when the first contact assembly 12 is in its proximate position.
Preferably, as shown in fig. 5, the locking mechanism 16 may include a locking member 161 elastically connected to the vertical portion 14 movably back and forth, and having a locking position at a front side and a releasing position at a rear side. The lock member 161 may be fixed to the measuring feeler 132 so that when the lock member 161 is in the lock position, the measuring feeler 132 is away from the workpiece to be measured, and when the lock member 161 is in the release position, the measuring feeler 132 may be moved to the approach position and measures the workpiece to be measured; or preferably, the locking member 161 and the measuring feeler 132 are matched through a mechanical structure such as an inclined plane, so that the measuring feeler 132 is slightly moved upwards away from the workpiece to be measured or downwards close to the workpiece to be measured by switching the locking member 161 between a locking position at the front side and a releasing position at the rear side, thereby further reducing the impact generated when the measuring feeler 132 contacts the workpiece to be measured and protecting the workpiece and the feeler. The locking mechanism 16 preferably comprises a crank mechanism by which the locking and releasing of the locking member 161 is manually controlled. As shown in fig. 5, the crank mechanism preferably includes: a hand crank 162 and an actuating member 163 vertically movably provided to the vertical portion 14 by the driving of the hand crank 162, the actuating member 163 being engaged with the locking member 161 to reciprocally switch the locking member 161 between the locking position and the releasing position by the vertical movement of the actuating member 163.
As shown in fig. 5, the actuator 163 includes: a sliding plate 1631 connected with the hand crank 162 and vertically movably disposed on the vertical portion 14, and an actuating rod 1632 vertically movably disposed on the sliding table and extending downward, wherein an extending portion of the sliding plate 1631 can interfere with the actuating rod 1632 in the vertical direction, and when the sliding plate 1631 moves downward under the operation of the hand crank 162, the extending portion of the sliding plate 1631 presses the actuating rod 1632 to move downward and simultaneously drives the sliding table 131 to move downward, so that the second contact assembly 13 moves to the approaching position. To reduce the impact of the sliding plate 1631 on the actuating rod 1632 in the above-described action, an elastic member such as a spring is preferably provided between the actuating rod 1632 and the slide table 131.
To facilitate the handling or placement of the workpiece to be measured, it is preferable to keep the second contact assembly 13 as far away from the workpiece to be measured as possible in the non-measuring state. Preferably, as shown in fig. 5, the sliding plate 1631 is fixedly provided with an upward lifting member 1633, and the lifting member 1633 is used for lifting the second contact assembly 13 to move upward from the close position to the remote position. When the sliding plate 1631 is controlled by the hand crank 162 to move upward, the jacking piece 1633 moves upward synchronously and pushes against the sliding table 131, so that the sliding table 131 and the second contact assembly 13 disposed thereon are away from the workpiece to be measured.
According to a preferred embodiment of the present application, the interlock mechanism restricts the second contact assembly 13 from moving to the proximate position when the first contact assembly 12 is in the distal position. When measuring a workpiece (such as a gear) to be measured, firstly, an operator controls the positioning contact 122 of the first contact assembly 12 to move to an approaching position through the manual operation part 15 so as to accurately position the workpiece to be measured; at this time, the interlock mechanism releases the second contact assembly 13, the operator controls the sliding plate 1631 to slide downward through the hand crank 162, and the extending portion of the sliding plate 1631 presses the actuating rod 1632, so that the sliding table 131 slides downward to the approaching position; continuing to press the actuating rod 1632, the actuating rod 1632 moves downward to move the locking member 161 from the locking position at the front side to the releasing position at the rear side against the elastic force of the elastic member between the actuating rod 1632 and the slide table 131, so as to release the measuring tip 132 to measure the workpiece to be measured.
As shown in fig. 5 and 6, the interlocking mechanism preferably includes: a first slider 21, the first slider 21 being fixedly connected to the first support 121 and moving back and forth on the table 11 together with the first support 121; a second slider 22, the second slider 22 being fixedly connected to the slide table 131 and moving up and down on the vertical portion 14 together with the slide table 131; and a releasable stopper structure disposed between the first slider 21 and the second slider 22 so that the first bracket 121 stops the downward movement of the second slider 22 when in the distant position of the first contact assembly 12 and allows the upward and downward movement of the second slider 22 when in the close position of the first contact assembly 12.
As shown in fig. 6, 7 and 8, the releasable stop structure preferably comprises: a guide rod 23, the guide rod 23 being fixedly mounted on the second slider 22 and extending downward; and a guide hole 24 opened in the first slider 21 and extending therethrough by the guide rod 23, the guide hole 24 having a radial dimension larger than that of the guide rod 23, the first slider 21 being pressed against the guide rod 23 to stop the downward movement of the second slider 22 when the first carrier 121 is at the distant position of the first contact assembly 12, and the first slider 21 being out of contact with the guide rod 23 at the close position of the first contact assembly 12. By means of the matching of the guide rod 23 and the guide hole 24, the distance that the first contact assembly 12 moves is too large or too small, the guide rod 23 cannot fall into the guide hole 24, that is, the second contact assembly 13 cannot move to the approaching position, and therefore the precision of the interlocking mechanism is further improved according to the size of the guide hole 24. As shown in fig. 8, the first slider 21 is preferably provided with a stopper plate 25, the stopper plate 25 blocks a portion of the guide hole 24, and the position of the stopper plate 25 on the first slider 21 is preferably adjustable, so that the size of the guide hole 24 is adjustable. The guide rod 23 is preferably provided with a planar portion 231 extending toward the stop plate 25 and along the vertical direction, so that the guide rod 23 is in a semi-cylindrical shape as a whole, and can be accurately matched with the guide hole 24 provided with the stop plate 25.
The measuring device with the interlock mechanism of the preferred embodiment described above enables the interlocking mating of the first contact assembly 12 and the second contact assembly 13 by means of the releasable stop structure of the measuring device. Specifically, when the first contact assembly 12 is located at the distant position, the guide rod 23 and the guide hole 24 are not aligned, in which case, when the operator erroneously operates the second contact assembly 13 to move to the close position, the guide rod 23 may interfere with the surface of the first slider 21 to prevent the second contact assembly 13 from moving to the close position; when an operator operates the first contact assembly 12 to the approaching position to position the part S to be measured, the guide rod 23 is aligned with the guide hole 24, and at this time, the second contact assembly 13 is operated to move to the approaching position, and the guide rod 23 can smoothly pass through the guide hole 24, so that the second contact assembly 13 can move to the approaching position.
The preferred embodiments of the present application have been described in detail above, but the present application is not limited to the specific details of the above embodiments, and various simple modifications can be made to the technical solution of the present application within the technical idea of the present application, and these simple modifications all belong to the protection scope of the present application.
It should be noted that, in the foregoing embodiments, various features described in the above embodiments may be combined in any suitable manner, and in order to avoid unnecessary repetition, various possible combinations are not described in the present application.
In addition, any combination of the various embodiments of the present application is also possible, and the same should be considered as disclosed in the present application as long as it does not depart from the idea of the present application.
