Abstract
The invention relates to a grinding paper clamp rod of a swinging arm type handheld grinding machine. The grinding paper clamp rod comprises a longitudinal trapezoidal groove which is formed in the upper end face of the grinding paper clamp rod, wherein a trapezoidal strip is arranged in the trapezoidal groove; a locating notch is formed in each of the left and right sides of the lower end of the trapezoidal strip; a stepped hole is formed in the rear end of the grinding paper clamp rod, a spring is arranged in the stepped hole, a button is connected into the spring, turning sheets are respectively connected to the left and right sides of the upper end of the button, strip-shaped holes I are respectively formed in the junctions between the turning sheets and the button, the middle parts of the turning sheets are respectively connected to the internal wall of the rear end of the trapezoidal groove, strip-shaped holes II are respectively formed in the other ends of the turning sheets and are respectively connected with locating columns, and guiding rails which are used for limiting the locating columns to vertical linear movement are arranged at the upper parts of the locating columns. According to the grinding paper clamp rod of the swinging arm type handheld grinding machine, the trapezoidal strip is snapped into the trapezoidal groove, the upper edge of the trapezoidal groove is of an acute angle, and the frictional force between grinding paper and the interior of the trapezoidal groove is enormous after the two edges of the grinding paper bypass the upper edge of the trapezoidal groove and are snapped into the trapezoidal groove, so that the grinding paper difficultly falls out of the trapezoidal groove, and the stability of clamping of the grinding paper is guaranteed.
Description
Technical field
The present invention relates to grinding apparatus technical field, specifically a kind of swing arm hand-held sander sand paper folder rod.
Background technology
Corrosion is the modal wear form of metal, as long as there is the place of oxygen and water, it is not all the time along with metal, especially metal-iron that the mankind are the most frequently used, iron rust is a kind of henna material, and it is so hard unlike iron, is easy to come off, after one block of iron gets rusty completely, volume can swell 8 times.If iron rust removes not in time, because spongiform iron rust especially easily absorbs moisture, the iron in iron rust also just gets rusty faster.
In the industrial production, iron rust is more common, the raw metal piled up or melter product are after a period of time shelves, because steam in factory is comparatively large, metal is as easy as rolling off a log there is phenomenon of getting rusty, and the raw metal got rusty or melter product affect the Forming Quality of product, waste raw material, in order to remove rusty stain in time, people commonly use sand paper and polish, or the electric grinding machine that service efficiency is higher.
Existing sander mostly is electric angle grinder, due to reasons in structure, this sanding machine needs inclination certain angle when using, thus little with Metal Contact face, also namely buffed surface is little, for the veined structure of surperficial tool, this sanding machine is difficult to deeply polish along texture, and is easily polished by texture when doing the polishing machine polishing of turnover motion.
When adopting sand paper to polish, buffed surface is comparatively large, and sand paper is different from bistrique, and bistrique contains metal handle, and bistrique making requires high, and cost is high, and sand paper manufacture is simple, and cost is lower.
In order to lower-cost sand paper can be utilized better, and play the advantage people such as sand papering area is large and need a kind of sand paper can being fixed up to carry out the clamping device of certain forms polishing, and easily wear and tear due to sand paper, require clamping device to have and change the easy feature of sand paper.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of swing arm hand-held sander sand paper folder rod.
The present invention solves its technical problem and realizes by the following technical solutions:
A swing arm hand-held sander sand paper folder rod, comprises and is positioned at the dovetail groove that sand paper presss from both sides the longitudinal direction of excellent upper surface.
Be provided with in described dovetail groove with dovetail groove with the use of trapezoidal bar; The lower end of described trapezoidal bar is each side provided with a positioning recess for being clamped by trapezoidal bar.
The rear end of described sand paper folder rod is provided with a shoulder hole, a spring is provided with in described shoulder hole, button is connected with in spring, described button upper end passes in dovetail groove, the button left and right sides is all connected with rotor by hinged mode, described rotor and button junction are equipped with a bar hole, the middle part of rotor is all connected on the inwall of dovetail groove rear end by hinged mode, the other end of rotor is equipped with No. two bar holes, described No. two bar holes are all connected with locating dowel by hinged mode, the top of described locating dowel is provided with the guide rail for locating dowel being restricted to upper and lower rectilinear motion, press the button and rotor can be driven to rotate, the pin joint of button and rotor slides in a bar hole, the pin joint of button and locating dowel slides in No. two bar holes, locating dowel does vertical translator movement in guide rail simultaneously.
The upper rear end of described dovetail groove is provided with and allows material mouth for what place trapezoidal bar end.
Described allowing expects that mouth is rectangular recess, and the rear end of described trapezoidal bar is provided with the step coordinated with rectangular recess, fully to be inserted in dovetail groove by trapezoidal bar, ensures that positioning recess has enough spaces to move to the position be positioned at directly over locating dowel.
The distance that described guide rail presss from both sides excellent upper surface to sand paper is topmost greater than the distance of positioning recess bottom surface to trapezoidal bar upper surface, the height of described step is greater than guide rail topmost to the distance of dovetail groove lower surface, ensures that trapezoidal bar step when inserting in dovetail groove can not occur interfering with guide rail.
The invention has the beneficial effects as follows: trapezoidal bar is stuck in dovetail groove by the present invention, the trapezoidal bar made can not move up and down in dovetail groove, and due to the top edge of dovetail groove be acute angle, the top edge two edges of sand paper being walked around dovetail groove is stuck in after in dovetail groove, frictional force in sand paper and dovetail groove is very big, can ensure that sand paper is not easily deviate from the dovetail groove clamped by trapezoidal bar, ensure that the clip stability to sand paper.
The positioning states of locating dowel in dovetail groove is controlled by button control rotor, simplify the positioning action of the trapezoidal bar of manipulation in dovetail groove, ensure that the positioning stablity of positioning strip in locating slot, by the frictional force effect between positioning recess and locating dowel, in conjunction with the resilient support of spring to button, locating dowel is difficult to deviate from positioning recess, dovetail groove and trapezoidal bar connective stability strong.
