Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of coal mining, especially relates to a adjustable assembly positioning mechanism for hydraulic support structural member. BACKGROUND

[0002] The main components of the hydraulic support structural member include a top beam, a shield beam, a base, a front connecting rod, a rear connecting rod and a push rod, which are combined together through welding, pin shaft connection and other modes to form a complete hydraulic support, wherein the balance ear seat is an important component in the shield beam or the top beam structure, and there is close relevance between the hinge hole of the shield beam or the top beam and the balance ear seat hole, which cooperates together to ensure the stability and good working performance of the hydraulic support. In production practice, in order to ensure the assembly position between the two, a positioning plate tool is usually designed according to the assembly position of the parts to ensure the accuracy and stability of the workpiece in the assembly process. Through accurate clamping and positioning design, the positioning plate tool can effectively prevent the workpiece from shifting or deforming in the machining process, reduce the scrap rate and rework rate, and thus ensure the assembly accuracy.

[0003] However, due to the diversification of the sizes of the top beam, the shield beam and the balance ear seat of the hydraulic support, the design of the fixed positioning plate tool is usually targeted at specific products, so its applicable range is relatively limited, that is, each set of tool can only be applied to the corresponding product, and cannot be reused after use. When the product changes, the fixed tooling may not be able to adapt to the new requirements. At the same time, the design, manufacture and storage of the same type of different size tools usually require a large amount of time, resources and space, including materials, equipment, labor and the like.

[0004] Therefore, the fixed tooling lacks flexibility and has relatively high cost. INVENTION CONTENTS

[0051] In order to better explain the utility model, so as to facilitate understanding, the following will be combined with the specific embodiments, the utility model is described in detail. Wherein, the "upper", "lower", "left", "right" and other orientation terms mentioned in this paper are with the direction of the figure as the reference. Figure 1 .

[0052] The adjustable assembly positioning mechanism for the hydraulic support structure part provided in the embodiment of the utility model realizes the adjustment of the transverse and longitudinal distances by using the guide block with the cross-shaped groove and the fastener to set the transverse positioning plate and the longitudinal positioning plate into the form of mutual perpendicularity and slidable connection, then abutting the transverse positioning plate and the longitudinal positioning plate on the positioning shaft and the reference shaft respectively, so that the two can realize the axial movement along the shaft, using the positioning sleeve to position the shaft, the hinged hole and the balance ear seat hole, to realize the adjustment of the axial distance. Thus, the assembly positioning mechanism can be adjusted in the transverse, longitudinal and axial directions, can better adapt to different models of products, has high flexibility, at the same time, without the need to produce various sizes of tooling, greatly reduces the production cost of the tooling.

[0053] For better understanding of the above technical solutions, the following will refer to the drawings more detailed description of the exemplary embodiments of the present application. Although the drawings show the exemplary embodiments of the present application, however, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. Instead, these embodiments are provided to enable a clearer, more thorough understanding of the present application, and to enable the scope of the present application to be fully conveyed to those skilled in the art.

[0054] Embodiment 1:

[0055] Referring to Figure 1 and Figure 2 , because of the close relationship between the hinge hole 101 of the shield beam 10 and the balance ear seat hole 201, both of which work together to ensure the stability and good performance of the hydraulic support, therefore the adjustable assembly positioning mechanism for the structural parts of the hydraulic support shown in the present application is an auxiliary mechanism used when assembling the balance ear seat 20 in the shield beam 10 to ensure the accuracy of the assembly. The present application is not an improvement on the structure or assembly method of the shield beam 10 and the balance ear seat 20 itself, so the specific structure and relationship of the shield beam 10 and the balance ear seat 20 will not be described in detail.

[0056] Referring to Figure 3 and Figure 4 , the adjustable assembly positioning mechanism for the structural parts of the hydraulic support shown in the present embodiment comprises a reference shaft 1 (such as Figure 14 ), a positioning shaft 2 (such as Figure 15 ), a transverse positioning plate 3 (such as Figure 5 ), a longitudinal positioning plate 4 (such as Figure 6 ), a guide block 5 (such as Figure 7 ), a fastener 6 and a positioning sleeve 7 (such as Figures 10 to 13 ).

[0057] The guide block 5 is a square structure with a cross recess 51, and a circular hole 52 is provided at the center of the cross recess 51. The circular hole 52 is a through hole, the middle part of the transverse positioning plate 3 is provided with a first long circular hole 31 along the length direction, and the middle part of the longitudinal positioning plate 4 is also provided with a second long circular hole 41 along the length direction. The transverse positioning plate 3 and the longitudinal positioning plate 4 are vertically stacked in the cross recess 51 and connected by the fastener 6, that is, the fastener 6 is sequentially inserted through the circular hole 52 in the middle of the guide block 5 and the first long circular hole 31 of the transverse positioning plate 3 and the second long circular hole 41 of the longitudinal positioning plate 4. The order of the transverse positioning plate 3 and the longitudinal positioning plate 4 stacked up and down can be freely adjusted. By sliding the fastener 6 in the first long circular hole 31 and the second long circular hole 41, the transverse positioning plate 3 and the longitudinal positioning plate 4 are connected in a cross shape in the cross recess 51, that is, the transverse positioning plate 3 and the longitudinal positioning plate 4 can slide in two directions perpendicular to each other (i.e. horizontally or vertically).

[0058] In this embodiment, as Figures 8 to 10 As shown, the horizontal and vertical grooves of the cross groove 51 have different depths. The horizontal depth is the sum of the thicknesses of the horizontal positioning plate 3 and the vertical positioning plate 4, while the vertical depth is the thickness of a single positioning plate, i.e., the thickness of either the horizontal positioning plate 3 or the vertical positioning plate 4. Preferably, the two positioning plates are set to have the same thickness. Setting the cross groove 51 to different depths ensures that after installation, the horizontal positioning plate 3 and the vertical positioning plate 4 fit more closely to the cross groove 51, resulting in better stability. The fastener 6 preferably uses bolts and nuts. The bolts are passed sequentially through the guide block 5, the transverse positioning plate 3, and the longitudinal positioning plate 4 and screwed into the nuts. The diameter of the bolts is smaller than the width of the first elongated hole 31 and the second elongated hole 41. Therefore, the transverse positioning plate 3 and the longitudinal positioning plate 4 can slide freely along the opening direction of the cross groove 51, while the outer diameter of the nuts is larger than the width of the first elongated hole 31 and the second elongated hole 41, which can play a stopping role. The nuts can not only ensure that the transverse positioning plate 3 and the longitudinal positioning plate 4 will not fall off, but can also be used to lock and fix the relative position between the positioning plates after adjusting the appropriate position. In order to ensure that the nut end can play a better stopping role, a flat washer or a large washer can be added to the end of the nut that contacts the transverse positioning plate 3 or the longitudinal positioning plate 4. While ensuring the stopping effect, it can also play a certain role in protecting the surface of the positioning plate and improving the stability of the connection.

[0059] Meanwhile, one end of the longitudinal positioning plate 4 can abut against the reference shaft 1, and one end of the transverse positioning plate 3 can abut against the positioning shaft 2. Both can move simultaneously along the axial direction of the reference shaft 1 and the axial direction of the positioning shaft 2.

[0060] In use, the reference shaft 1 is inserted into the hinge hole 101, and the positioning shaft 2 is inserted into the balance ear hole 201. By adjusting the position of the longitudinal positioning plate 4 abutting on the reference shaft 1 and the transverse positioning plate 3 abutting on the positioning shaft 2, the axial distance between the shield beam 10 and the balance ear 20 of different models can be adapted. This structure can adapt to different models of products and is very convenient. Then, the transverse positioning plate 3 and the longitudinal positioning plate 4 are adjusted to determine the transverse and longitudinal distances between the hinge hole 101 and the balance ear hole 201, that is, the transverse and longitudinal distances between the two holes are reflected on the positions of the transverse positioning plate 3 and the longitudinal positioning plate 4. Furthermore, the distance from the abutting end of the positioning plate to the guide block 5 can be measured by setting scale lines on the transverse positioning plate 3 and the longitudinal positioning plate 4 or by using additional measuring tools (such as a measuring tape), thereby determining the transverse and longitudinal distances between the hinge hole 101 and the balance ear hole 201 to ensure the assembly accuracy between the two. This assembly and positioning mechanism can be adjusted in three directions: horizontal, vertical, and axial. It can better adapt to different product models, offering high flexibility. At the same time, it eliminates the need to produce tooling of various sizes, greatly reducing the production cost of tooling.

[0061] In this embodiment, in order to conveniently adjust the distance between the transverse positioning plate 3 and the longitudinal positioning plate 4, a first scale line 34 is arranged on the transverse positioning plate 3 along the length direction, the length of the first scale line 34 is greater than or equal to the length of the first long circular hole 31, and the first scale line 34 is arranged offset to the direction in which the first long circular hole 31 abuts against the positioning shaft 2, and the offset distance is half the width of the guide block 5, so that when the guide block 5 is located at the most end position of the first long circular hole 31 in the direction of abutting against the positioning shaft 2, the side edge of the guide block 5 can be aligned with the zero position of the first scale line 34, that is, as shown in the figure. Figure 2 When placed, when the guide block 5 is located at the limit position on the right side of the transverse positioning plate 3, the right side edge of the guide block 5 is aligned with the starting numerical position of the first scale line 34.

[0062] A second scale line 44 is arranged on the longitudinal positioning plate 4 along the length direction, the length of the second scale line 44 is greater than or equal to the length of the second long circular hole 41, and the second scale line 44 is arranged offset to the direction in which the second long circular hole 41 abuts against the reference shaft 1, and the offset distance is half the height of the guide block 5, so that when the guide block 5 is located at the most end position of the second long circular hole 41 in the direction of abutting against the reference shaft 1, the bottom edge of the guide block 5 can be aligned with the zero position of the second scale line 44, that is, as shown in the figure. Figure 2 When placed, when the guide block 5 is located at the limit position on the lower side of the longitudinal positioning plate 4, the bottom edge of the guide block 5 is aligned with the starting numerical position of the second scale line 44.

[0063] The arrangement of the scale line not only improves the efficiency of adjusting the positioning plate but also improves the accuracy of the adjustment, the scale line can clearly identify the scale that needs to be adjusted, avoids the situation that measurement error is easily caused by using additional measurement tools, and the square guide block 5 not only limits the directions of the transverse positioning plate 3 and the longitudinal positioning plate 4 but also plays a role in reading the scale, that is, the size corresponding to the left end of the guide block 5 is the scale size of the transverse positioning plate 3, and the size corresponding to the lower end of the guide block 5 is the scale size of the longitudinal positioning plate 4, wherein the zero position refers to the reference value set according to the actual situation, and is not necessarily the scale 0.

[0064] In order to make the positioning plate and the shaft more convenient and more precise abutment, the transverse positioning plate 3 is provided with a first U-shaped groove 32 at the end abutting with the positioning shaft 2, the opening size of the first U-shaped groove 32 needs to be adapted to the outer diameter of the positioning shaft 2, that is, the transverse positioning plate 3 can be inserted on the positioning shaft 2 through the first U-shaped groove 32; the longitudinal positioning plate 4 is provided with a second U-shaped groove 42 at the end abutting with the reference shaft 1, the opening size of the second U-shaped groove 42 needs to be adapted to the outer diameter of the reference shaft 1, that is, the longitudinal positioning plate 4 can be inserted on the reference shaft 1 through the second U-shaped groove 42. Of course, the shape of the abutting end of the positioning plate can also be designed by those skilled in the art according to actual needs, as long as it can be fitted with the shape of the shaft and easily abutted, for example, a semicircular groove. In the embodiment, the transverse positioning plate 3 is provided with protrusions 35 on the opposite sides of the first U-shaped groove 32, the positions of the protrusions 35 are correspondingly arranged with the positions of the first U-shaped groove 32, so as to ensure the strength of the transverse positioning plate 3 at the position of the bottom of the first U-shaped groove 32.

[0065] In order to more conveniently operate the positioning plate, the transverse positioning plate 3 is provided with a first handle 33 at the end position away from the positioning shaft 2, and the longitudinal positioning plate 4 is provided with a second handle 43 at the end position away from the reference shaft 1, which not only can more conveniently move the positioning plate, but also can more stably control the positioning plate to avoid the danger of slipping during use. In the embodiment, the first handle 33 and the second handle 43 are both square through holes, of course, they can also be other shapes convenient to grasp, for example, oval through holes or circular through holes, etc., which can be freely set by those skilled in the art according to actual needs.

[0066] In the embodiment, in order to fix the reference shaft 1 after penetrating into the hinged hole 101 and the positioning shaft 2 after penetrating into the balance ear seat hole 201 to facilitate measurement.

[0067] The reference shaft 1 is provided with axially movable trapezoidal positioning sleeves 71 at both shaft ends, the reference shaft 1 is an optical axis, the inner hole of the trapezoidal positioning sleeve 71 is a through hole which can be gap-fitted with the reference shaft 1, the outer diameter is a trapezoidal structure including a large diameter section 711 and a small diameter section 712, and the large diameter sections 711 of the trapezoidal positioning sleeves 71 at both ends of the reference shaft 1 are oppositely arranged. During installation, the reference shaft 1 penetrates through the hinged holes 101 on both sides of the cover beam 10 and the trapezoidal positioning sleeves 71 in sequence, then the trapezoidal positioning sleeves 71 are moved to the hinged holes 101 on both sides respectively, until the small diameter section 712 penetrates into the hinged hole 101, and the step between the large diameter section 711 and the small diameter section 712 abuts on the outer side wall of the hinged hole 101, that is, the installation is in place. At the same time, in order to facilitate the penetration of the reference shaft 1, small shaft ends 11 with smaller diameters are arranged at both end positions. The outer diameter size of the small diameter section 712 needs to be adapted to the size of the hinged hole 101, and when the size of the hinged hole 101 changes, the trapezoidal positioning sleeve 71 also needs to be redesigned to be adapted thereto.

[0068] The two axial ends of the positioning shaft 2 are provided with axially movable conical positioning sleeves 72, the middle section of the positioning shaft 2 in contact with the transverse positioning plate 3 is an optical axis section 21, both ends are threaded sections 22, the inner hole of the conical positioning sleeve 72 is provided with an internal thread that can be screwed with the threaded section, and the outer diameter is a conical structure that can better adapt to the balance lug hole 201 of different sizes, and the small diameter ends of the two conical positioning sleeves 72 are oppositely arranged. When installing, first pass the positioning shaft 2 through the balance lug hole 201 on both sides, then screw the two conical positioning sleeves 72 into the two ends of the positioning shaft 2 respectively, until the conical surface part of the conical positioning sleeve 72 enters the balance lug hole 201 and abuts against each other, that is, it is installed in place, at this time the conical positioning sleeve 72 is used in cooperation with the positioning shaft 2, has a locking effect, and can prevent sliding.

[0069] In this embodiment, trapezoidal positioning sleeves 71 are used on the reference shaft 1, and conical positioning sleeves 72 are used on the positioning shaft 2. Because the hole diameter of the hinge hole 101 is generally larger, if the conical positioning sleeve 72 is used, the size of the conical positioning sleeve 72 will also be relatively large, and when it is screwed with the reference shaft 1, it is not very convenient to operate, so the trapezoidal positioning sleeve 71 that can be directly moved in cooperation with the shaft gap is selected; the hole diameter of the balance lug hole 201 is generally smaller, so the conical positioning sleeve 72 is selected, which can adapt to different models of balance lug 20 and has higher adaptability.

[0070] At the same time, in this embodiment, the positioning shaft 2, the transverse positioning plate 3 and the longitudinal positioning plate 4 are all arranged in parallel along the axial direction of the reference shaft 1, so as to facilitate the simultaneous adjustment of the two groups of balance lug holes 201 opposite the hinge hole 101, and the efficiency is higher. Of course, the present application is not limited to this, and those skilled in the art can set one or more groups according to actual needs. This assembly positioning mechanism has the advantages of simple structure, strong flexibility and adaptability, low manufacturing cost and convenient use. It is a general tool that can be repeatedly used for assembling and positioning the balance lug of the top beam and the cover beam structural member, and can achieve the purposes of improving quality, reducing cost and increasing efficiency.

[0071] In the embodiment, the middle section of the reference shaft 1 is preferably machined from a steel pipe with a diameter of φ62mm / φ94mm; the two ends of the positioning shaft 2 are machined with coarse threads with a diameter of φ40mm; the transverse positioning plate 3 is machined from a steel plate with a thickness of 8mm, the width of the first U-shaped groove 32 is 40mm, and the width of the first long circular hole 31 is 12mm; the longitudinal positioning plate 4 is also machined from a steel plate with a thickness of 8mm, the width of the second U-shaped groove 42 is 62mm / 92mm, and the width of the second long circular hole 41 is 12mm; the small-diameter section 712 of the trapezoidal positioning sleeve 71 is machined from a steel pipe; the inner side of the conical positioning sleeve 72 is a coarse thread structure that matches the threads on the positioning shaft 2, and the conical positioning sleeve 72 can match a hole diameter range of φ50mm-φ100mm.

[0072] The following is a brief description of the operation steps of using the assembly positioning mechanism of embodiment 1:

[0073] Step one: pass the reference shaft 1 through the hinge hole 101 and the trapezoidal positioning sleeve 71 in sequence, and the two trapezoidal positioning sleeves 71 can be placed between the two hinge holes 101 on the sides in advance.

[0074] Step two: move the two trapezoidal positioning sleeves 71 towards the hinge hole 101 on the side, until the small-diameter section 712 is inserted into the hinge hole 101, and the step between the large-diameter section 711 and the small-diameter section 712 abuts against the outer side wall of the hinge hole 101, i.e. installed in place.

[0075] Step three: insert the positioning shaft 2 into the balance ear seat hole 201.

[0076] Step four: screw the two conical positioning sleeves 72 from the two ends of the positioning shaft 2, respectively, until the conical surface part of the conical positioning sleeve 72 enters the balance ear seat hole 201 and abuts against each other, i.e. installed in place (the same operation is performed on the other set of positioning shaft 2).

[0077] Step five: insert the longitudinal positioning plate 4 through the second U-shaped groove 42 on the reference shaft 1, and insert the transverse positioning plate 3 through the first U-shaped groove 32 on the positioning shaft 2.

[0078] Step six: observe the scales on the transverse positioning plate 3 and the longitudinal positioning plate 4 to check whether the relative positions between the hinge hole 101 and the balance ear seat hole 201 are accurate, if there is deviation, the position of the balance ear 20 can be adjusted according to the measurement results.

[0079] In the initial installation stage, the assembly positioning mechanism can also be used to assist in the installation of the shield beam 10 and the balance ear 20.

[0080] Embodiment 2:

[0081] The adjustable assembly positioning mechanism for the hydraulic support structural member shown in the embodiment is different from that of the embodiment 1 in that the trapezoidal positioning sleeves 71 are selected at both ends of the reference shaft 1 and the positioning shaft 2, and the other parts are the same as those of the embodiment 1, which will not be repeated here.

[0082] In the embodiment, the trapezoidal positioning sleeves 71 are selected for both the reference shaft 1 and the positioning shaft 2, because when the trapezoidal positioning sleeves 71 are selected, the machining of the reference shaft 1 and the positioning shaft 2 is simpler, without the need to machine the threaded sections, and the installation of the trapezoidal positioning sleeves 71 is relatively easier, which only needs to be pushed into the hole. Both the machining of the assembly positioning mechanism itself and the use in engineering are more convenient. However, the adaptability of this method is lower, and it is more suitable for the case where the hole diameters of the hinged holes 101 and the balance lug seat holes 201 are not frequently adjusted.

[0083] Embodiment 3:

[0084] The adjustable assembly positioning mechanism for the hydraulic support structural member shown in the embodiment is different from that of the embodiment 1 in that the trapezoidal positioning sleeves 71 are selected at both ends of the reference shaft 1 and the positioning shaft 2, and the other parts are the same as those of the embodiment 1, which will not be repeated here.

[0085] In the embodiment, the trapezoidal positioning sleeves 71 are selected for both the reference shaft 1 and the positioning shaft 2, because when the trapezoidal positioning sleeves 71 are selected, the machining of the reference shaft 1 and the positioning shaft 2 is simpler, without the need to machine the threaded sections, and the installation of the trapezoidal positioning sleeves 71 is relatively easier, which only needs to be pushed into the hole. Both the machining of the assembly positioning mechanism itself and the use in engineering are more convenient. However, the adaptability of this method is lower, and it is more suitable for the case where the hole diameters of the hinged holes 101 and the balance lug seat holes 201 are not frequently adjusted.

[0086] Of course, the utility model is not limited to the above embodiments, and the selection of the positioning sleeve 7 can be selected according to actual needs by those skilled in the art, but the positioning sleeves 7 on the same shaft should be consistent and arranged in pairs, and the structure of the reference shaft 1 and the positioning shaft 2 also needs to be matched with the selected positioning sleeve 7, that is, when the trapezoidal positioning sleeve 71 is used, the shaft should be the optical axis; when the conical positioning sleeve 72 is used, the shaft should be the middle section in contact with the positioning plate, which is the optical axis section 21, and the two ends are the threaded sections 22.

[0087] The use scene of the adjustable assembly positioning mechanism for the hydraulic support structural member shown in the utility model is not limited to the above embodiments, and it can also be used for the assembly and positioning of the top beam and the balance lug seat, and the specific use method is similar to that of the embodiment 1, which basically replaces the shield beam in the embodiment 1 with the top beam, and the details will not be repeated here. In the utility model, the balance lug seat is equivalent to the lug plate, because this assembly positioning mechanism is mainly used to determine the relative position between the hinged hole and the balance lug seat hole or the lug plate hole, and is not limited by the specific structure of the balance lug seat and the lug plate.
