Description

Technical Field

[0001] The present application relates to the technical field of optical filter attachment, and in particular to a clamping fixture, an ejector mechanism, and an optical filter attachment device. Background Art

[0002] When the filter is being attached, the ejector mechanism is extended and retracted to lift the neatly arranged filters in the material tray to a certain height, thereby separating the filter from the original material tray for subsequent attachment. The existing ejector mechanism includes a support seat and an ejector rod. The support seat is provided with a positioning groove for installing the ejector rod and a fastening screw hole connected to the positioning groove. One end of the ejector rod is inserted into the positioning groove and then screwed into the fastening screw hole by a screw. The end of the screw abuts against the side of the ejector rod, thereby completing the locking of the ejector rod. In the actual operation process, due to the reciprocating lifting and lowering of the ejector mechanism, the screw is prone to loosening over time. Since the screw and the ejector rod are in point contact, after the screw is loosened, the ejector rod is prone to sliding and tilting in the positioning groove, which leads to large fluctuations in the accuracy of the ejector rod lifting, resulting in poor attachment of the filter.

[0031] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] The disclosure below provides many different embodiments or examples for implementing different structures of the embodiments of the present application. In order to simplify the disclosure of the embodiments of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the embodiments of the present application. In addition, the embodiments of the present application may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0033] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.

[0034] In order to solve the problems in the prior art, the present application provides a clamping jig, a pin mechanism and a filter attachment device. The clamping jig can effectively alleviate or even prevent the sliding and tilting of the pin rod, thereby ensuring the accuracy of the pin rod lifting and the quality of the filter attachment.

[0035] like Figure 1-6 As shown, an embodiment of the present application provides a clamping fixture, including: a support platform 1 and a clamping assembly 3.

[0036] The support platform 1 has a mounting portion 11 for mounting the ejector rod 2. The mounting portion 11 is provided with a telescopic groove 111 and a clamping groove 112. The clamping groove 112 is located in the telescopic groove 111. The inner diameter of the clamping groove 112 can change with the change of the width of the telescopic groove 111, and is used to clamp the ejector rod 2 located in the clamping groove 112.

[0037] The clamping assembly 3 is disposed on the support platform 1 , and the clamping assembly 3 is used to change the width of the telescopic slot 111 .

[0038] In the present application, the width of the telescopic slot 111 is changed by the clamping assembly 3. When the width of the telescopic slot 111 is reduced, the inner diameter of the clamping slot 112 is simultaneously reduced, thereby realizing the clamping and locking of the ejector rod 2 by the clamping slot 112. Compared with the prior art in which the ejector rod 2 is locked by point contact, the present application fixes the ejector rod 2 by surface contact, which can effectively alleviate or even avoid the sliding and tilting of the ejector rod 2, thereby ensuring the lifting accuracy of the ejector rod 2 and the quality of the attachment of the filter a.

[0039] In the related art, the existing ejector mechanism includes a support base and an ejector rod 2. The support base is provided with a positioning groove for mounting the ejector rod 2 and a fastening screw hole connected to the positioning groove. One end of the ejector rod 2 is inserted into the positioning groove and then screwed into the fastening screw hole by a screw. The end of the screw abuts against the side of the ejector rod 2, thereby completing the locking of the ejector rod 2. In actual operation, due to the reciprocating lifting and lowering of the ejector mechanism, the screw is prone to loosening over time. Since the screw and the ejector rod 2 are in point contact, after the screw is loosened, the ejector rod 2 is prone to sliding and tilting in the positioning groove, which in turn causes large fluctuations in the lifting accuracy of the ejector rod 2, resulting in poor attachment of the filter a. Moreover, the filter a attachment equipment has very high requirements for the dust-free working environment. In order to ensure the positioning effect of the positioning groove on the ejector rod 2, the inner diameter of the positioning groove is slightly larger than the diameter of the mounting end of the ejector rod 2. When the mounting end of the ejector rod 2 is inserted into the positioning groove, dust is generated between the ejector rod 2 and the positioning groove due to relative sliding, which increases the dust amount in the working environment and affects the quality of the attachment of the filter a.

[0040] The clamping groove 112 is formed on the inner surface of the support 1 and the outer surface of the support 1 is fixed to the support 1 by the fixing means 112. The fixing means 112 is fixed to the support 1 by the fixing means 112 and the fixing means 112 is fixed to the support 1 by the fixing means 112.

[0041] In some embodiments, the clamping groove 112 includes a first state and a second state. When the clamping groove 112 is in the first state, the inner diameter of the clamping groove 112 is greater than the diameter of the ejector rod 2; when the clamping groove 112 is in the second state, the inner diameter of the clamping groove 112 is equal to the diameter of the ejector rod 2.

[0042] In the present application, when the clamping groove 112 is in the first state, the inner diameter of the clamping groove 112 is larger than the diameter of the ejector rod 2, which makes it convenient to insert the mounting end of the ejector rod 2 into the clamping groove 112, and in the process of inserting the mounting end of the ejector rod 2 into the clamping groove 112, the sliding between the clamping groove 112 can be effectively reduced. When the ejector rod 2 is installed in place, the axial positioning of the ejector rod 2 is completed, and there will be no axial relative sliding between the ejector rod 2 and the clamping groove 112. Then, the clamping groove 112 is driven by the clamping assembly 3 to switch to the second state. At this time, the inner diameter of the clamping groove 112 is equal to the diameter of the mounting end of the ejector rod 2, and the clamping groove 112 fully wraps the mounting end of the ejector rod 2, thereby ensuring the fixing effect of the ejector rod 2, alleviating or even avoiding the sliding and tilting of the ejector rod 2, and ensuring the lifting accuracy and attachment quality of the filter a.

[0043] In some embodiments, the extension direction of the telescopic slot 111 is parallel to the radial direction of the support platform 1 , and the clamping slot 112 extends along the axial direction of the support platform 1 .

[0044] In the present application, the extension direction of the telescopic groove 111 is parallel to the radial direction of the support platform 1, and passes through the mounting portion 11 of the support platform 1, ensuring that the mounting portion 11 can change the width of the telescopic groove 111 after being squeezed by the clamping assembly 3. The clamping groove 112 extends along the axial direction of the support platform 1, and the extension direction of the clamping groove 112 is perpendicular to the extension direction of the telescopic groove 111. When the width of the telescopic groove 111 becomes smaller, the inner diameter of the clamping groove 112 can be reduced, thereby clamping and locking the ejector rod 2 located in the clamping groove 112.

[0045] In some embodiments, the mounting portion 11 includes a fixing plate 113 and a clamping plate 114 arranged on both sides of the fixing plate 113, and a telescopic groove 111 is formed between the clamping plate 114 and the fixing plate 113; the clamping groove 112 includes: a first half groove 1121, arranged on the side of the fixing plate 113 facing the clamping plate 114; and a second half groove 1122, arranged on the side of the clamping plate 114 facing the fixing plate 113, and arranged opposite to the first half groove 1121.

[0046] In this application, the fixed plate 113 is located between the two clamping plates 114, and the clamping assembly 3 applies pressure to the clamping plates 114 on both sides, so that the clamping plates 114 are deformed toward the fixed plate 113, so that the distance between the clamping plates 114 and the fixed plate 113 becomes smaller, and the clamping groove 112 includes a first half groove 1121 located on the fixed plate 113 and a second half groove 1122 located on the clamping plate 114. The distance between the first half groove 1121 and the second half groove 1122 is reduced, thereby achieving a reduction in the inner diameter of the clamping groove 112, so that the clamping groove 112 clamps and locks the ejector rod 2.

[0047] Specifically, the width of the fixed plate 113 along the width direction of the telescopic slot 111 is greater than the width of the clamping plate 114 along the width direction of the telescopic slot 111. The clamping plate 114 can undergo a certain deformation along the width direction of the telescopic slot 111, while the position of the fixed plate 113 remains unchanged, thereby more accurately positioning the position of the ejector rod 2.

[0048] Specifically, at least two clamping grooves 112 are provided in each telescopic groove 111. By changing the width of the telescopic groove 111, that is, the clamping plate 114 is deformed toward the fixed plate 113, the inner diameters of the multiple clamping grooves 112 in the telescopic groove 111 can be changed synchronously. Compared with the situation in the prior art where each ejector rod 2 is tightened by a bolt, the consistency of the positions of the multiple clamping grooves 112 in the same telescopic groove 111 can be ensured, and the positioning effect of the ejector rod 2 can be further improved.

[0049] In a specific embodiment, the number of the clamping grooves 112 in the telescopic groove 111 in the present application is two.

[0050] In some embodiments, the first half groove 1121 and the second half groove 1122 are respectively arc-surface structures for fitting the outer circumference of the ejector rod 2 .

[0051] In the present application, the mounting end of the ejector rod 2 is a cylindrical structure. By setting the first half groove 1121 and the second half groove 1122 to an arc surface structure, the first half groove 1121 and the second half groove 1122 are fully fitted with the outer peripheral surface of the ejector rod 2, further increasing the contact area between the clamping groove 112 and the ejector rod 2, thereby further improving the fixing effect and positioning effect of the ejector rod 2.

[0052] Optionally, in the case where the cross section of the ejector rod 2 is polygonal, the first half groove 1121 and the second half groove 1122 can be configured to be shaped to match the ejector rod 2 to ensure the fixing and positioning effects of the ejector rod 2 .

[0053] In some embodiments, the support platform 1 further includes a support plate 12 , the fixing plate 113 and the clamping plate 114 are respectively connected to the support plate 12 , and the clamping groove 112 is connected to the support plate 12 at one end thereof facing the support plate 12 .

[0054] In the present application, the fixing plate 113 and the clamping plate 114 are both connected to the support plate 12, and the fixing plate 113 and the clamping plate 114 are arranged on the top of the support plate 12. The fixing plate 113, the clamping plate 114 and the support plate 12 are integrally processed and formed to ensure the accuracy of the position of the fixing plate 113. The thickness of the clamping plate 114 is relatively thin so that it can be deformed toward the fixing plate 113 and is used to clamp the ejector rod 2.

[0055] In one embodiment, a fitting surface 1141 is provided on the side of the clamping plate 114 away from the fixed plate 113, and a first through-hole is provided on the fixed plate 113 and the clamping plate 114 along the width direction of the telescopic slot 111. The clamping assembly 3 includes: two clamping blocks 31, which are respectively fitted with the fitting surfaces 1141 of the two clamping plates 114; and a fastener 32, which passes through the first through-hole on the fixed plate 113 and the clamping plate 114. The fastener 32 connects the two clamping blocks 31 to apply a locking force to the two clamping blocks 31 to move toward each other.

[0056] In the present application, the two clamping blocks 31 are respectively in contact with the contact surfaces 1141 of the two clamping plates 114. The fastener 32 passes through the first through-hole and connects the two clamping blocks 31, exerting a locking force on the two clamping blocks 31 so as to cause the two clamping plates 114 to deform toward the fixed plate 113. Specifically, the fastener 32 is a bolt, with a through-hole provided on one clamping block 31 and a threaded hole provided on the other clamping block 31. The bolt passes through the through-hole and is threadedly connected to the threaded hole. By rotating the bolt, the locking force exerted on the two clamping blocks 31 is exerted so as to cause the two clamping blocks 31 to move toward each other.

[0057] Specifically, after the clamping block 31 is in contact with the contact surface 1141 of the clamping plate 114, the area of ​​the contact surface 1141 between the clamping block 31 and the clamping plate 114 is increased, ensuring that the amount of deformation of the entire clamping plate 114 toward the fixed plate 113 remains consistent, thereby ensuring the positioning accuracy of the ejector rod 2 within the multiple clamping slots 112 within the telescopic slot 111. The clamping block 31 contacts the support plate 12, which supports the clamping block 31 and positions the clamping block 31 axially along the support platform 1, facilitating the connection between the clamping assembly 3 and the support platform 1.

[0058] Moreover, by providing two clamping blocks 31 , the deformation amounts of the two clamping plates 114 toward the fixed plate 113 can be kept consistent, thereby ensuring the positioning effect of the ejector rod 2 .

[0059] In another embodiment, the clamping plate 114 includes a first clamping plate 1142 and a second clamping plate 1143, and the first clamping plate 1142 is provided with a fitting surface 1141 on the side away from the fixed plate 113, the first clamping plate 1142 and the fixed plate 113 are provided with a second through-hole along the width direction of the telescopic groove 111, and the second clamping plate 1143 is provided with a threaded groove along the width direction of the telescopic groove 111; the clamping assembly 3 includes: a clamping block 31, which is fitted with the fitting surface 1141 of the first clamping plate 1142; and a fastener 32, which passes through the second through-hole and is threadedly connected to the threaded groove, and the fastener 32 connects the clamping block 31 and the second clamping plate 1143 to apply a locking force to the clamping block 31 and the second clamping plate 1143 to move toward each other.

[0060] In the present application, only one clamping block 31 can be provided, and the fastener 32 is a bolt. The bolt passes through the through hole on the first clamping block 31 and then passes through the two second through holes in sequence, and then is threadedly connected to the threaded groove on the second clamping plate 1143. Similarly, the two clamping plates 114 can be deformed toward the fixed plate 113, and the ejector rod 2 in the clamping groove 112 can be clamped and locked.

[0061] Optionally, the clamping assembly 3 may also include two U-shaped clamps, which are clamped on the outside of the two clamping plates 114 through the U-shaped clamps, and then abut against the clamping plates 114 through the fastening bolts on the clamps, thereby causing the clamping plates 114 to deform toward the fixed plate 113.

[0062] In some embodiments, the support platform 1 further includes a mounting post 13 connected to the support plate 12 . A positioning member 131 is provided on the mounting post 13 . The positioning member 131 is used to position the support platform 1 .

[0063] In this application, the positioning part 131 is a rod. When installing the ejector mechanism inside the equipment, the staff can adjust the angle of the ejector mechanism by identifying the positioning part 131. During subsequent routine maintenance, the positioning part 131 can also be used to identify the direction to avoid installation misalignment and achieve a fool-proof effect.

[0064] In some embodiments, an introduction groove 1123 is provided at an open end of the clamping groove 112 .

[0065] In the present application, the introduction groove 1123 at the top of the clamping groove 112 facilitates the insertion of the ejector rod 2 into the clamping groove 112 and plays a guiding role.

[0066] Specifically, the introduction groove 1123 is of a gradually expanding design and can be a chamfered structure or a rounded structure.

[0067] The clamping fixture changes the width of the telescopic slot 111 through the clamping assembly 3. When the width of the telescopic slot 111 is reduced, the inner diameter of the clamping slot 112 is synchronously reduced, thereby achieving the clamping and locking of the clamping slot 112 on the ejector rod 2. Compared with the prior art in which the ejector rod 2 is locked by point contact, the present application fixes the ejector rod 2 by surface contact, which can effectively alleviate or even prevent the ejector rod 2 from sliding and tilting, thereby ensuring the lifting accuracy of the ejector rod 2 and the quality of the attachment of the filter a.

[0068] An embodiment of the present application provides an ejector mechanism, comprising: an ejector rod 2; and the above-mentioned clamping fixture.

[0069] In the present application, the ejector rod 2 is installed in the clamping groove 112 of the clamping fixture, and the ejector rod 2 is locked after clamping by the clamping assembly 3. The ejector rod 2 and the clamping groove 112 of the clamping fixture are locked through surface contact, which can ensure the fixing and positioning effect of the ejector rod 2, and effectively alleviate or even prevent the ejector rod 2 from sliding and tilting in the clamping groove 112 in the future.

[0070] Specifically, there are four clamping grooves 112 and two telescopic grooves 111. Each telescopic groove 111 is provided with two clamping grooves 112. The four ejector rods 2 are positioned respectively through the four clamping grooves 112. The filter a in the material tray is lifted up by the four ejector rods 2, so that the filter a is separated from the material tray, so as to carry out subsequent attachment operations.

[0071] An embodiment of the present application provides a filter a attaching device, including the above-mentioned ejector mechanism.

[0072] In this application, the filter a attaching device also includes a material tray, and the filters a are neatly arranged in the material tray. The filter a in the material tray is lifted up by the ejector mechanism, thereby separating the filter a from the material tray and performing subsequent filter a attaching operations.
